Suche oczy
Epidemiologia

Suchość oczu to złożona choroba charakteryzująca się niestabilnością filmu łzowego, hiperosmolarnością i stanem zapalnym powierzchni oka. Epidemiologia wskazuje na zmienną częstość występowania od 5% do 50%, z wyższą zapadalnością w populacjach azjatyckich, szczególnie w Chinach, Tybecie i Korei. Metaanalizy szacują, że 10-20% osób powyżej 40. roku życia doświadcza umiarkowanych do ciężkich objawów. W USA częstość występowania wynosi 6,8%, z wyższą zapadalnością u kobiet i wzrostem ryzyka o 25% na każdą dekadę życia. Czynniki ryzyka obejmują niemodyfikowalne aspekty demograficzne (wiek, płeć żeńska, pochodzenie azjatyckie) oraz modyfikowalne czynniki środowiskowe i stylu życia, takie jak niska wilgotność, długotrwałe korzystanie z ekranów (>6 godzin dziennie), palenie tytoniu i stosowanie kosmetyków do oczu. Schorzenia współistniejące, takie jak zespół Sjögrena (1-2% populacji, 90% kobiet), migrena, cukrzyca, niedobór androgenów i choroby tarczycy, również zwiększają ryzyko. Dysfunkcja gruczołów Meiboma (MGD) jest najczęstszym podtypem, występującym u ponad 86% pacjentów z suchym okiem.

Epidemiologia suchego oka

Suche oczy to wieloczynnikowa choroba charakteryzująca się niestabilnością filmu łzowego, hiperosmolarnością oraz stanem zapalnym powierzchni oka. Zrozumienie epidemiologii suchego oka oraz rozpoznanie czynników ryzyka, zarówno modyfikowalnych jak i niemodyfikowalnych, może pomóc lekarzom w ocenie, leczeniu i zarządzaniu pacjentami z tym schorzeniem123.

Występowanie suchego oka na świecie

Szacunki dotyczące występowania suchego oka różnią się znacznie w zależności od zastosowanych kryteriów diagnostycznych, a także ciężkości schorzenia i charakterystyki demograficznej badanej populacji12. Badania epidemiologiczne przeprowadzone na całym świecie wskazują, że częstość występowania suchego oka waha się od 5% do 50%, przy czym najwyższe wartości obserwuje się w krajach azjatyckich (głównie w Chinach, Tybecie i Korei)123.

Metaanaliza opublikowanych danych dotyczących występowania suchego oka szacuje, że ostrożne wskaźniki chorobowości wskazują, że 10-20% populacji powyżej 40. roku życia zgłasza umiarkowane do ciężkich objawów i/lub szuka leczenia z powodu suchego oka12. W Stanach Zjednoczonych, na podstawie danych z National Health and Wellness Survey z 2017 roku, 6,8% dorosłej populacji zostało zdiagnozowanych z suchym okiem, przy czym częstość występowania wzrasta wraz z wiekiem i jest większa u kobiet niż u mężczyzn1.

Występowanie objawów jest zwykle niższe i mniej zmienne niż występowanie klinicznych objawów suchego oka. Badania, w których diagnoza opierała się głównie na objawach przedmiotowych, generalnie wykazywały wyższe i bardziej zmienne wskaźniki choroby, sięgające nawet 75% w niektórych populacjach1.

Regionalne różnice w występowaniu

Bayesowska analiza 30 badań dotyczących częstości występowania opublikowanych między 1997 a 2021 rokiem wykazała globalną częstość występowania objawowej choroby na poziomie 9,12%. Występowanie było wyższe wśród kobiet (9,5%) niż wśród mężczyzn (6,8%). Pod względem geograficznym, najwyższą częstość występowania wykazała Afryka (47,9%), a następnie Azja Południowa (32,0%), Azja Zachodnia (29,0%), Azja Wschodnia (19,4%), Oceania (14,9%), Ameryka Południowa (14,7%), Europa (13,7%) i Ameryka Północna (4,6%)1.

Częstość występowania suchego oka wydaje się być nieco wyższa w Azji niż na innych kontynentach1. Na przykład w Tajwanie badanie populacyjne dotyczące chorób oczu wykazało, że 33,7% osób starszych miało objawy, zdefiniowane jako zgłaszanie jednego lub więcej objawów suchego oka1.

W innych regionach świata również przeprowadzono badania:

  • W Dubaju częstość występowania suchego oka szacuje się na 62,6%, przy czym ciężka postać suchego oka jest najbardziej rozpowszechniona (42% przypadków)12
  • W Arabii Saudyjskiej częstość występowania wynosi od 32,1% do 62,4%1
  • W Argentynie ogólna częstość występowania suchego oka wyniosła 42,1%, częstość u kobiet wynosiła 45,1%, a u mężczyzn 30,8%1
  • W Palestynie częstość występowania suchego oka wyniosła 64%12
  • W São Paulo w Brazylii ogólna częstość występowania suchego oka wyniosła 24,4%12

Czynniki demograficzne wpływające na występowanie suchego oka

Osoby z określonymi niemodyfikowalnymi czynnikami demograficznymi mogą być bardziej narażone na rozwój suchego oka1. Kluczowymi niemodyfikowalnymi cechami demograficznymi predysponującymi do suchego oka są:

Wiek

Częstość występowania suchego oka wzrasta liniowo z wiekiem1. Wzrost częstości występowania wraz z każdą dekadą życia jest większy w przypadku klinicznych objawów suchego oka w porównaniu z objawami zgłaszanymi przez pacjentów12. Średnio, każda dekada życia wiązała się z 25% zwiększonym ryzykiem rozwoju choroby suchego oka1.

Co ciekawe, wykryto przejściowe opóźnienie między pojawieniem się klinicznych objawów dysfunkcji gruczołów Meiboma (MGD) a innymi markerami suchego oka, w tym niestabilnością filmu łzowego, hiperosmolarnością, epiteliopatią wycieraczki powiekowej i objawami suchego oka, które pojawiają się głównie w czwartej dekadzie życia, między 33 a 38 rokiem życia1.

Płeć

Suche oko występuje częściej u kobiet niż u mężczyzn12. Badania wykazały, że płeć żeńska jest czynnikiem ryzyka w rozwoju suchego oka, z częstością występowania wahającą się od 12% do 22%1. Różnice stają się istotne dopiero wraz z wiekiem1.

W Stanach Zjednoczonych, retrospektywna analiza danych od 9,7 miliona beneficjentów Department of Defense Military Health System (DOD MHS) wykazała ogólną częstość występowania suchego oka na poziomie 5,28%, z wyższą częstością wśród kobiet będących beneficjentkami MHS (7,78%) w porównaniu do mężczyzn będących beneficjentami MHS (2,96%)1.

Pochodzenie etniczne

Pochodzenie azjatyckie jest głównie spójnym czynnikiem ryzyka1. Suche oko jest bardziej powszechne u osób czarnoskórych i populacji azjatyckich w porównaniu z osobami białymi, chociaż różnice geograficzne, klimatyczne i środowiskowe mogą również być istotnymi czynnikami1.

Dane na temat rasy i pochodzenia etnicznego w chorobie suchego oka są ograniczone, ale częstość i diagnoza kliniczna suchego oka wydają się być większe w populacjach latynoskich i azjatyckich niż u białych1.

Czynniki ryzyka suchego oka

Czynniki ryzyka suchego oka można podzielić na modyfikowalne i niemodyfikowalne1.

Czynniki systemowe

Schorzenia systemowe, które zostały powiązane ze zwiększonym ryzykiem suchego oka, obejmują:

  • Migrenę123
  • Zespół Sjögrena – suche oko związane z zespołem Sjögrena dotyczy według szacunków 1-2% populacji, a 90% chorych to kobiety123
  • Zaburzenia tkanki łącznej12
  • Zaburzenia zdrowia psychicznego12
  • Cukrzycę123
  • Niedobór androgenów12
  • Choroby tarczycy12
  • Nadciśnienie – było istotnie związane z objawami suchego oka (OR=1,98; 95% CI 1,14-3,43, p=0,015) i rozpoznaniami (OR=3,54; 95% CI 1,92-6,53, p=0,0001) u kobiet1
Czynniki oczne i jatrogenne

Znaczący wpływ na rozwój suchego oka mają:

  • Dysfunkcja gruczołów Meiboma (MGD) – jest uważana za najczęstszy podtyp suchego oka1. Ponad 86% osób z suchym okiem wykazuje objawy MGD1. W badaniu pacjentów przed operacją zaćmy, MGD był czynnikiem ryzyka najsilniej związanym z suchym okiem (test chi-kwadrat Pearsona = 88,542, p 0,001, = 0,58; stosunkowo silna siła)1
  • Przewlekłe zapalenie powiek1
  • Skrzydlik1
  • Alergiczne zapalenie spojówek1
  • Noszenie soczewek kontaktowych12
  • Przeszczep krwiotwórczych komórek macierzystych12
  • Poprzednia operacja zaćmy1
  • Operacja refrakcyjna (np. LASIK)1
  • Stosowanie leków wpływających na produkcję łez lub stabilność filmu łzowego1
  • Stosowanie kropli do oczu z konserwantami1
Czynniki stylu życia

Zidentyfikowano szereg modyfikowalnych czynników stylu życia, które mogą zwiększać ryzyko suchego oka, w tym:

  • Środowiska o niskiej wilgotności12
  • Korzystanie z cyfrowych ekranów – Wykazano związek między suchym okiem a liczbą godzin korzystania z ekranu, większą niż 6 godzin dziennie1234
  • Jakość snu12
  • Dieta12
  • Noszenie kosmetyków do oczu12
  • Palenie tytoniu1

Suche oko w różnych grupach populacyjnych

Zmiany demograficzne w populacji z suchym okiem

Dawniej suche oko było kojarzone głównie z kobietami w okresie okołomenopauzalnym, ale obecnie obraz demograficzny tej choroby ulega zmianie1. Częstość występowania suchego oka zwiększa się wśród młodych dorosłych w wieku 18-34 lat, głównie z powodu zwiększonego używania miękkich soczewek kontaktowych oraz częstego korzystania ze smartfonów i komputerów1.

„Twarz suchego oka zmienia się wraz z używaniem urządzeń cyfrowych, a normalna częstotliwość mrugania 20 razy na minutę spada do 3 razy na minutę. […] Suche oko kiedyś dotyczyło 60-, 70-letniej kobiety, teraz dotyczy 15- i 25-latków”1.

Suche oko u dzieci

Szacowana częstość występowania suchego oka wśród dzieci wynosi 23,7% (95% CI 18,5% do 28,9%). Co istotne, częstość występowania suchego oka po wybuchu pandemii COVID-19 wyniosła 44,1% (95% CI 25,5% do 62,7%; 8 badań; 9163 dzieci), co było znacznie wyższe niż 18,7% (95% CI 15,6% do 21,9%; 34 badania, 39 316 dzieci; p=0,01) przed wybuchem COVID-191.

Co interesujące, wydaje się, że istnieje wysoka częstość występowania suchego oka (60,5-90%) wśród młodych populacji i dzieci szkolnych1.

Suche oko w kontekście pandemii COVID-19

Podczas globalnej pandemii COVID-19 wiele krajów wprowadziło ograniczenia lub inne restrykcje, aby zapobiec rozprzestrzenianiu się wirusa1. Badanie przeprowadzone wśród studentów uniwersyteckich w Chile podczas pandemii COVID-19 wykazało, że 77,5% studentów doświadczało objawów suchego oka1.

Badanie ankietowe przeprowadzone online wśród studentów medycyny w Tajlandii podczas trzeciej fali pandemii COVID-19 w 2022 roku wykazało częstość występowania objawów suchego oka na poziomie 60,4%1. Podczas pandemii, poziom stresu i zaburzenia snu zostały zidentyfikowane jako czynniki zaostrzające objawy suchego oka1.

Obciążenie ekonomiczne i wpływ na jakość życia

Obciążenie ekonomiczne związane z suchym okiem można przypisać bezpośrednim wydatkom na opiekę medyczną, wpływowi utraty produktywności oraz wpływowi na jakość życia1.

Analiza ekonomiczna ujawnia, że średni roczny koszt leczenia pacjenta z suchym okiem wynosi 783 dolary w Stanach Zjednoczonych. Po uwzględnieniu częstości występowania suchego oka w skali kraju, ogólne obciążenie suchego oka dla systemu opieki zdrowotnej w USA wyniosłoby około 3,84 miliarda dolarów12.

Suche oko negatywnie wpływa na jakość życia związaną ze zdrowiem i wzrokiem, upośledzając zdolność ludzi do pełnego zaangażowania w działania zawodowe i rekreacyjne oraz wykonywania normalnych codziennych czynności1. Ponieważ choroba dotyka miliony osób pracujących, może nakładać znaczne obciążenie ekonomiczne na system opieki zdrowotnej w USA i społeczeństwo, głównie w postaci zmniejszonej produktywności1.

Wpływ suchego oka na jakość życia i samopoczucie psychiczne jest znaczący1. Jakość życia może być znacznie upośledzona u pacjentów z suchym okiem1. Panel ekspertów zgodził się, że wpływ suchego oka na jakość życia pacjentów powinien być brany pod uwagę przy zarządzaniu chorobą1.

Prognozy i kierunki przyszłych badań

Częstość występowania suchego oka prawdopodobnie będzie nadal rosła1. Ogólnie rzecz biorąc, częstość występowania suchego oka prawdopodobnie wzrośnie wraz ze starzeniem się populacji w Stanach Zjednoczonych i na całym świecie1.

W epidemiologii potrzeba więcej badań dotyczących suchego oka w populacjach poniżej 40 roku życia, naturalnej historii suchego oka z leczeniem i bez, czynników ryzyka, pośrednich kosztów wynikających z utraconej produktywności oraz oszczędności kosztów wynikających z leczenia1.

Z obecnej bazy dowodów wynika jasna potrzeba dalszych prospektywnych badań podłużnych w celu ustalenia, czy rozwój i progresja współistniejących chorób ocznych i ogólnoustrojowych poprzedzają suche oko, czy też występują jako konsekwencja tego stanu. Większa spójność w metodologii badań i definicjach choroby w badaniach epidemiologicznych jest potrzebna, aby umożliwić lepsze porównania między badaniami i ocenić siłę związku między suchym okiem a czynnikami etiologicznymi1.

Istnieje również znaczna potrzeba badań epidemiologicznych opartych na populacji dotyczących suchego oka w regionie Bliskiego Wschodu i Północnej Afryki1. Standaryzacja diagnostyki suchego oka u dzieci i dalsze badania innych czynników ryzyka są potrzebne, aby w pełni wyjaśnić epidemiologię suchego oka u dzieci1.

    Dry eye disease is a multifactorial condition characterised by tear film instability, hyperosmolarity and ocular surface inflammation. Understanding the epidemiology of dry eye disease and recognising both modifiable and non-modifiable risk factors can assist eye care practitioners in assessing, treating, and managing patients with the condition. This review considers current knowledge surrounding its incidence and prevalence, as well as associated demographic, systemic, ocular, and iatrogenic, and lifestyle-related modifiable risk factors. […] Population-based prevalence estimates vary according to the diagnostic criteria used to define dry eye disease, as well as severity and demographic characteristics of the population. Considering recent data and variable population demographics, conservative prevalence estimates suggest that 10-20% of the population over 40 years of age report moderate to severe symptoms and/or seek treatment for dry eye disease.

    Dry eye disease (DED) is a multifactorial disease of the ocular surface with loss of homeostasis of the tear film and ocular symptoms. DED is also known as keratoconjunctivitis sicca, dry eye syndrome, and dysfunctional tear syndrome. […] The epidemiology, pathophysiology, clinical presentation, diagnosis, and treatment options for DED will be reviewed here. Various conditions associated with DED are discussed separately. […] In epidemiologic studies performed globally, the prevalence of DED ranges from 5 to 50 percent, with persons living in Asia (principally China, Tibet, Korea) having a higher prevalence. The wide range in prevalence is due to different definitions of DED being used, as well as variation in study populations. […] Based on data from the 2017 National Health and Wellness Survey, 6.8 percent of the United States adult population has been diagnosed with DED, with an increasing prevalence with older age and greater prevalence in women than men. In a 2022 meta-analysis of three United States studies, the prevalence ranged from 5.3 to 14.5 percent with an estimated pooled prevalence of 8.1 percent. […] Risk factors for DED include.

    Prevalence of disease for studies involving symptoms with or without signs ranged from approximately 5% to 50%. Studies where the diagnosis was based primarily on signs generally reported higher and more variable rates of disease, up to 75% in certain populations. […] The prevalence of DED increases linearly with age. The increase in prevalence by decade is greater with clinical signs of dry eye compared with symptoms report and with self-report of a clinical diagnosis. Similarly, the rate of MGD increases linearly with age. […] The weight of evidence from large epidemiologic studies confirms that female sex and older age increase the risk for DED. Other substantiated risk factors include MGD, hematopoietic stem cell transplantation, computer use, Asian race, contact lens wear, Sjgren syndrome, environmental hazardous conditions such as pollution, low humidity, systemic connective diseases, and certain classes of medications including antihistamines, antidepressants, anxiolytics and isotretinoin.

    Dry eye is extremely common, especially in older individuals. It is the most commonly reported reason for seeking ophthalmologic medical care. Various epidemiological studies have found a prevalence range of 5-50%, depending on the geographic region and age of the studied population. […] A Bayesian analysis of 30 prevalence studies published between 1997 and 2021 found a global prevalence for symptomatic disease of 9.12%. Prevalence was higher among women (9.5%) than among men (6.8%). Geographically, Africa showed the highest prevalence (47.9%), followed by Southern Asia (32.0%), Western Asia (29.0%), Eastern Asia (19.4%), Oceania (14.9%), South America (14.7%), Europe (13.7%) and North America (4.6%). […] In the United States (US), a retrospective analysis of data from 9.7 million beneficiaries of the Department of Defense Military Health System (DOD MHS) revealed an overall DES prevalence of 5.28%, with a higher prevalence among female MHS beneficiaries (7.78%) compared to male MHS beneficiaries (2.96%).

    The prevalence of dry eye appears slightly higher in Asia than other continents. […] The economic burden of DED can be attributed to direct medical care spending, the impact of loss of productivity, and impact on quality of life. […] The prevalence mapping described here could also be used to examine overlap with the human development index (a composite statistic of life expectancy, education, and income per capita) and the distributions of different dry eye interventions.

    Dry eye disease (DED) has become common on a global scale in recent years. There is a wide prevalence of DED in different countries based on various ethnicities and environment. DED is a multifactorial ocular disorder. […] We report the DED epidemiology in Taiwan firstly in this article. According to a cohort study through the National Health Insurance Research Database (NHIRD) from 2000 to 2008 in Taiwan, the incidence rates of developing Sjogren’s syndrome were 4.8% for the group of dry eye disease and 1.5% for the comparison group. In addition, patients with DED presented for Sjogren’s syndrome were diagnosed 3.88 years earlier than the patients in the comparison group. […] The prevalence of dry eye disease varies globally in different places, ranging from 7% in the United States to over 30% in Taiwan, Japan and Korea. It is believed that this difference in the prevalence of DED between Asian and Western populations is based on ethnic variability. In Taiwan, a population-based survey of eye disease showed that 33.7% of the elderly were symptomatic, defined as reporting one or more dry-eye symptoms.

    Individuals with specific non-modifiable demographic risk factors may be at increased risk of developing dry eye disease. […] Advanced age, female sex and East Asian ethnicity have been identified as key non-modifiable demographic features predisposing individuals to dry eye disease. […] Systemic conditions that have been associated with an increased risk of dry eye disease include migraine, Sjögren syndrome, connective tissue disorders, mental health disorders, diabetes mellitus and androgen deficiency. […] A range of modifiable lifestyle factors that can increase the risk of dry eye disease have also been identified, including low humidity environments, digital screen use, quality of sleep, diet, and eye cosmetic wear.

    On average, each decade of life was associated with 25% increased odds of developing dry eye disease. […] Interestingly, a transient delay was detected between the appearance of clinical signs of MGD and other markers of DED, including tear film instability, hyperosmolarity, lid wiper epitheliopathy and dry eye symptoms, which predominantly emerged during the fourth decade of life, between the ages of 33 and 38 years. […] Finally, and of importance to clinicians relying on ocular surface staining in dry eye diagnosis, corneal and conjunctival staining were among the last clinical signs of DED to emerge in the natural history of progression. Such signs of ocular surface damage typically arose between the ages of 46 and 52 years and were more likely to represent moderate-to-severe dry eye disease.

    Dry eye is more common in women than men (due to female hormonal effects on the lacrimal and Meibomian glands and ocular surface) and has an increased prevalence with age. Studies have shown that female gender is a risk factor in developing dry eye, with a prevalence that ranges from 12% to 22%. The prevalence of DED worldwide varies depending on the diagnostic criteria employed, which ranges from approximately 5% to 50% in population-based studies. […] DES has been shown to be as high as 70% in visual terminal users. In general, it is more common in Black individuals and Asian populations when compared with White individuals, although geographic, climatic, and environmental variations may also be significant factors. […] Evaporative dry eye is considered the most common subtype of DED. There may be discordance between dry eye signs and symptoms, with signs being more prevalent and variable than symptoms.

    The subcommittee reviewed the prevalence, incidence, risk factors, natural history, morbidity and questionnaires reported in epidemiological studies of dry eye disease (DED). A meta-analysis of published prevalence data estimated the impact of age and sex. Global mapping of prevalence was undertaken. The prevalence of DED ranged from 5 to 50%. The prevalence of signs was higher and more variable than symptoms. There were limited prevalence studies in youth and in populations south of the equator. The meta-analysis confirmed that prevalence increases with age, however signs showed a greater increase per decade than symptoms. Women have a higher prevalence of DED than men, although differences become significant only with age. Risk factors were categorized as modifiable/non-modifiable, and as consistent, probable or inconclusive. Asian ethnicity was a mostly consistent risk factor. The economic burden and impact of DED on vision, quality of life, work productivity, psychological and physical impact of pain, are considerable, particularly costs due to reduced work productivity.

    Influencing factors remain constant despite diagnostic criteria used, and include sex, age and geographic location. Prevalence increases linearly with age, and females are more affected according to the report. Prevalence appears higher in Asian than in Caucasian populations, though studies have not been conducted in all major geographic regions. Peri- and postmenopausal females seem to be particularly at a higher risk. In addition, hormonal studies demonstrate that sex hormones influence ocular surface conditions through their effects on aqueous tear secretion, meibomian gland function and conjunctival goblet cell density. […] Diabetes and other systemic conditions, such as connective tissue diseases, Sjögren’s syndrome (SS) and thyroid disease have also been associated with DED prevalence.

    The prevalence of dry eyes reported by our study (62.6%) was similar to that found in the population of the Eastern Province of Saudi Arabia (65.4%) and to the Jordanian population (59%). […] The present study also found an association between using contact lenses and the OSDI score. […] The high prevalence of dry eyes indicates the need for early diagnosis and treatment before complications occur. […] This study was the first cross-sectional study conducted in Dubai to determine the prevalence of dry eyes, which was found to be 62.6% in Dubai in 2019. […] We identified an association between female sex, a high amount of average daily screen time, the use of contact lenses, and dry eyes. […] However, age, a history of eye injury, and exposure to smoking/shisha were not found to be associated with dry eyes.

    A systematic review and meta-analysis of prevalence (reported by 10 studies) and incidence (reported by 2 studies) of DES in the US estimated an overall prevalence of 8.1% (range 5.3-14.5%) and a 5-year incidence of 3.5% among adults 18 years of age and 7.8% among adults 68 years of age. […] These include older age, female sex (and, relatedly, estrogen therapy in postmenopausal women or androgen deficiency), use of systemic antihistamines, LASIK and refractive surgery, radiation therapy, vitamin A deficiency, hepatitis C (HCV) infection and haematopoietic stem cell transplantation (HSCT).
  • #2 Middle East Preferred Practice Patterns for Dry Eye Disease: A Modified Delphi Consensus
    https://openophthalmologyjournal.com/VOLUME/15/PAGE/34/FULLTEXT/
    Dry Eye Disease (DED) is a common ophthalmic condition resulting from dysfunction in the ocular surface, main lacrimal gland, meibomian glands, or connecting nerves. […] In the Middle East, epidemiological data on the prevalence of DED are scarce, but prevalence rates have been reported to be 8.7% in Iran and 59% in Jordan. In Saudi Arabia, dry eye symptoms were reported in 32.1% of an adult population. […] Quality of life can be significantly impaired in patients with DED. […] The economic burden of DED is high, with an estimated direct cost of $3.84 billion per year in the United States of America. […] Local challenges relating to DED in the Middle East include poor patient education concerning DED, lack of a proper general practitioner system, irregular follow-up, high rates of refractive eye surgery, high rates of contact lens wear, and environmental factors.
  • #3 Epidemiology and Risk Factors of Dry Eye Disease: Considerations for Clinical Management
    https://ouci.dntb.gov.ua/en/works/lebP1jE9/
    Dry eye disease is a multifactorial condition characterised by tear film instability, hyperosmolarity and ocular surface inflammation. […] Understanding the epidemiology of dry eye disease and recognising both modifiable and non-modifiable risk factors can assist eye care practitioners in assessing, treating, and managing patients with the condition. […] This review considers current knowledge surrounding its incidence and prevalence, as well as associated demographic, systemic, ocular, and iatrogenic, and lifestyle-related modifiable risk factors. […] Population-based prevalence estimates vary according to the diagnostic criteria used to define dry eye disease, as well as severity and demographic characteristics of the population. […] Considering recent data and variable population demographics, conservative prevalence estimates suggest that 10–20% of the population over 40 years of age report moderate to severe symptoms and/or seek treatment for dry eye disease.

    Prevalence of disease for studies involving symptoms with or without signs ranged from approximately 5% to 50%. Studies where the diagnosis was based primarily on signs generally reported higher and more variable rates of disease, up to 75% in certain populations. […] The prevalence of DED increases linearly with age. The increase in prevalence by decade is greater with clinical signs of dry eye compared with symptoms report and with self-report of a clinical diagnosis. Similarly, the rate of MGD increases linearly with age. […] The weight of evidence from large epidemiologic studies confirms that female sex and older age increase the risk for DED. Other substantiated risk factors include MGD, hematopoietic stem cell transplantation, computer use, Asian race, contact lens wear, Sjgren syndrome, environmental hazardous conditions such as pollution, low humidity, systemic connective diseases, and certain classes of medications including antihistamines, antidepressants, anxiolytics and isotretinoin.
  • #3 The epidemiology of dry eye disease
    https://www.nzoptics.co.nz/live-articles/the-epidemiology-of-dry-eye-disease/
    The epidemiology of dry eye disease as a highly prevalent and often debilitating condition has recognised impacts on ocular comfort, visual function, work productivity, psychological well-being and quality of life-. The 2017 TFOS DEWS II Epidemiology report highlighted the paucity of studies in the literature investigating the risk factors and natural history of DED. […] Multivariate regression analysis showed that systemic rheumatological disease and antidepressant medication use were associated with increased odds of aqueous tear deficiency. Independent risk factors for meibomian gland dysfunction (MGD), the primary cause of evaporative dry eye disease, included advancing age, East Asian ethnicity, migraine headaches, thyroid disease and use of oral contraceptive therapy. […] Our associated, second study evaluated the impacts of ageing on the natural history of DED in a cohort of 1331 community residents.

    Individuals with specific non-modifiable demographic risk factors may be at increased risk of developing dry eye disease. […] Advanced age, female sex and East Asian ethnicity have been identified as key non-modifiable demographic features predisposing individuals to dry eye disease. […] Systemic conditions that have been associated with an increased risk of dry eye disease include migraine, Sjögren syndrome, connective tissue disorders, mental health disorders, diabetes mellitus and androgen deficiency. […] A range of modifiable lifestyle factors that can increase the risk of dry eye disease have also been identified, including low humidity environments, digital screen use, quality of sleep, diet, and eye cosmetic wear.

    The statistical analysis carried out allows us to highlight the significant risk factors that were identified, mainly the female sex and age over 60 years. […] The prevalence of DED increased with age in both sexes, but age is not a risk factor in the men’s group. […] The current study showed a higher prevalence of the symptoms or diagnosis of dry eye and the number of hours of screen use, greater than 6 h a day, according to what has been published, it would seem to have a potential proportional correlation. […] This is the first large population study performed in Argentina to evaluate DED and it is able to provide essential information regarding the epidemiological aspects.
