Zapalenie nerwu wzrokowego
Etiologia i przyczyny
Zapalenie nerwu wzrokowego (optic neuritis) to stan zapalny nerwu wzrokowego, najczęściej o podłożu autoimmunologicznym, prowadzący do demielinizacji i uszkodzenia nerwu, co skutkuje zaburzeniami widzenia. Najczęstszą przyczyną jest stwardnienie rozsiane (SM), u którego około 50% pacjentów rozwinie zapalenie nerwu wzrokowego, a ryzyko rozwoju SM po epizodzie zapalenia nerwu wzrokowego wynosi 30-60% w ciągu 10 lat, zależnie od obecności zmian w MRI. Inne istotne etiologie to zaburzenia ze spektrum choroby Devica (NMOSD) z obecnością autoprzeciwciał AQP4-IgG oraz choroba związana z przeciwciałami przeciwko glikoproteinie oligodendrocytów mieliny (MOGAD). W patogenezie obserwuje się reakcję autoimmunologiczną z uszkodzeniem osłonki mielinowej, infiltracją limfocytarną i obecnością prążków oligoklonalnych w płynie mózgowo-rdzeniowym u 60-70% pacjentów z izolowanym zapaleniem nerwu wzrokowego.

Etiologia zapalenia nerwu wzrokowego
Zapalenie nerwu wzrokowego (optic neuritis) to stan zapalny nerwu wzrokowego, który prowadzi do obrzęku i uszkodzenia tego nerwu, co skutkuje zaburzeniami widzenia. Dokładna przyczyna zapalenia nerwu wzrokowego nie jest w pełni poznana, jednak większość badaczy uważa, że głównym mechanizmem patofizjologicznym jest reakcja autoimmunologiczna, w której układ odpornościowy błędnie atakuje osłonkę mielinową otaczającą nerw wzrokowy, powodując stan zapalny i uszkodzenie mieliny.123
Mechanizm patofizjologiczny
Uważa się, że w przebiegu typowego zapalenia nerwu wzrokowego dochodzi do reakcji autoimmunologicznej uszkadzającej osłonkę mielinową otaczającą nerw wzrokowy. Badania wykazały, że u pacjentów z udokumentowanymi chorobami autoimmunologicznymi występuje większa skłonność do rozwoju zapalenia nerwu wzrokowego. Zaobserwowano również związek przyczynowy między HLA DRB1, HLA-B27 a tym schorzeniem.4
W przypadkach zapalenia nerwu wzrokowego związanego ze stwardnieniem rozsianym (SM), badania patologiczne wykazały, że odmielnione zmiany w nerwie wzrokowym są podobne do plak SM widocznych w mózgu, z odpowiedzią zapalną charakteryzującą się mankietami okołonaczyniowymi, komórkami T i komórkami plazmatycznymi. Natomiast niewiele wiadomo o patologii izolowanego zapalenia nerwu wzrokowego.5
W jedynym opisanym przypadku przewlekłego, izolowanego zapalenia nerwu wzrokowego, próbka biopsji wykazała obecność okołonaczyniowej infiltracji limfocytarnej, wieloogniskowej demielinizacji i reaktywnej astrocytozy w części pozagałkowej nerwu wzrokowego. Nieprawidłowa wewnątrzoponowa synteza IgG, odzwierciedlona jako obecność prążków oligoklonalnych w płynie mózgowo-rdzeniowym, jest obserwowana u 60-70% pacjentów z izolowanym zapaleniem nerwu wzrokowego, co sugeruje etiologię immunologiczną podobną do stwardnienia rozsianego.6
Klasyfikacja zapalenia nerwu wzrokowego
W zależności od etiologii, zapalenie nerwu wzrokowego można sklasyfikować jako typowe lub atypowe:
- Typowe zapalenie nerwu wzrokowego – występuje, gdy demielinizacja jest główną przyczyną patofizjologiczną. Ta klasyfikacja przypisuje manifestację zapalenia nerwu wzrokowego głównie stwardnieniu rozsianemu lub samodzielnej chorobie idiopatycznej, z których stwardnienie rozsiane jest najczęstszą podstawową etiologią wszystkich podtypów zapalenia nerwu wzrokowego.7
- Atypowe zapalenie nerwu wzrokowego – najczęściej występuje jako wczesna manifestacja zaburzeń ze spektrum choroby Devica (NMOSD), dawniej znanej jako zapalenie nerwów wzrokowych i rdzenia (NMO).8
Choroby demielinizacyjne jako przyczyna zapalenia nerwu wzrokowego
Choroby demielinizacyjne są najczęstszą przyczyną zapalenia nerwu wzrokowego w częściach świata, gdzie stwardnienie rozsiane jest powszechne, takich jak kraje północnoeuropejskie.9
Stwardnienie rozsiane
Stwardnienie rozsiane (SM) jest najczęstszą znaną przyczyną zapalenia nerwu wzrokowego. Zapalenie nerwu wzrokowego często jest pierwszym objawem SM i uważa się, że około 50% osób z SM rozwinie zapalenie nerwu wzrokowego w pewnym momencie przebiegu choroby.1011
Zapalenie nerwu wzrokowego jest objawem początkowym SM u 15-20% pacjentów i występuje u 50% w pewnym momencie przebiegu ich choroby.12 Badania wykazały, że zapalenie nerwu wzrokowego jest często pierwszym zdarzeniem, które sygnalizuje, że dana osoba ma SM, oraz że około 50% osób z typowym zapaleniem nerwu wzrokowego rozwinie SM w ciągu 15 lat.13
Szacuje się, że ryzyko rozwoju SM u osób, które miały zapalenie nerwu wzrokowego, w ciągu 10 lat wynosi 30-60%, w zależności od tego, czy w badaniu MRI widoczne są charakterystyczne zmiany.14
Choroba Devica (NMOSD)
Zaburzenie ze spektrum choroby Devica (NMOSD), dawniej znane jako zapalenie nerwów wzrokowych i rdzenia (NMO), to rzadka choroba zapalna demielinizacyjna charakteryzująca się zapaleniem nerwu wzrokowego w połączeniu z rozległym poprzecznym zapaleniem rdzenia kręgowego. NMOSD jest związane z obecnością specyficznego autoprzeciwciała w surowicy, NMO IgG, które atakuje kanał wodny akwaporynę-4.15
Około dwie trzecie lub więcej pacjentów z NMOSD ma przeciwciała IgG przeciwko akwaporynie-4 (AQP4-IgG), białku kanału wodnego, które występuje obficie na błonach astrocytów i w pobliżu bariery krew-mózg. Pacjentów seronegatywnych nie można klinicznie odróżnić od seropozytywnych. W chorobie seropozytywnej AQP4-IgG wiązanie AQP4-IgG z AQP4 na zakończeniach astrocytów inicjuje aktywację kaskady dopełniacza, infiltrację granulocytów do ośrodkowego układu nerwowego i cytotoksyczność komórkową zależną od przeciwciał.16
Choroba związana z przeciwciałami MOG
Choroba związana z przeciwciałami przeciwko glikoproteinie oligodendrocytów mieliny (MOG) może powodować zapalenie nerwu wzrokowego, rdzenia kręgowego lub mózgu.1718
Badania łączą atypowe zapalenie nerwu wzrokowego z chorobą zapalenia nerwów wzrokowych i rdzenia (NMO) oraz chorobą związaną z przeciwciałami przeciwko glikoproteinie oligodendrocytów mieliny (MOGAD).19
Choroby autoimmunologiczne jako przyczyna zapalenia nerwu wzrokowego
Badacze podejrzewają, że choroby autoimmunologiczne i zapalne są główną przyczyną lub czynnikiem przyczyniającym się do zapalenia nerwu wzrokowego. Podejrzewają również, że konkretne schorzenia autoimmunologiczne związane z tym stanem różnią się w zależności od typu zapalenia nerwu wzrokowego.2021
Osoby z chorobami autoimmunologicznymi, takimi jak toczeń rumieniowaty układowy, sarkoidoza i choroba Behçeta, mają większe ryzyko rozwoju zapalenia nerwu wzrokowego.22
Do chorób autoimmunologicznych, które mogą powodować zapalenie nerwu wzrokowego, należą:
- Toczeń rumieniowaty układowy (SLE)2324
- Sarkoidoza2526
- Choroba Behçeta2728
- Zespół Sjögrena2930
- Reumatoidalne zapalenie stawów31
- Astrocytopatia autoimmunologiczna związana z GFAP32
- Ostra rozsiana encefalomelitis (ADEM)33
- Przewlekła nawracająca zapalna neuropatia nerwu wzrokowego (CRION)34
Zakażenia jako przyczyna zapalenia nerwu wzrokowego
Zakażenia są często zdarzeniem wyzwalającym, które powoduje zapalenie nerwu wzrokowego, szczególnie w postaci dziecięcej.35 Niektóre badania sugerują, że choroby wirusowe, znane z wywoływania reakcji autoimmunologicznych, mogą indukować ataki zapalenia nerwu wzrokowego.36
Zapalenie nerwu wzrokowego może czasami wynikać z procesu zakaźnego obejmującego oczodół lub zatoki przynosowe, lub wystąpić w przebiegu ogólnoustrojowej infekcji wirusowej.37
Infekcje wirusowe
Infekcje wirusowe są częstą przyczyną zapalenia nerwu wzrokowego, szczególnie w postaci dziecięcej.38 Do wirusów, które mogą powodować zapalenie nerwu wzrokowego, należą:
- Herpes simplex3940
- Wirus ospy wietrznej i półpaśca4142
- Odra4344
- Świnka4546
- Różyczka47
- Cytomegalowirus48
- HIV49
- Wirus Zachodniego Nilu50
Infekcje bakteryjne
Do bakteryjnych zakażeń, które mogą powodować zapalenie nerwu wzrokowego, należą:
- Borelioza5152
- Kiła5354
- Choroba kociego pazura (Bartonella)5556
- Gruźlica5758
- Zapalenie opon mózgowo-rdzeniowych59
- Zapalenie zatok przynosowych60
Leki i toksyny jako przyczyna zapalenia nerwu wzrokowego
Niektóre leki i toksyny zostały powiązane z rozwojem zapalenia nerwu wzrokowego. Do substancji tych należą:
- Etambutol – stosowany w leczeniu gruźlicy6162
- Metanol – powszechny składnik płynów przeciw zamarzaniu, farb i rozpuszczalników6364
- Inhibitory TNF-alfa6566
- Inhibitory punktów kontrolnych układu immunologicznego6768
- Chinina6970
- Tetracyklina71
- Antybiotyki linezolidu72
- Amiodaron73
- Izoniazyd7475
- Ołów76
- Arsen77
Inne przyczyny zapalenia nerwu wzrokowego
Istnieje wiele innych potencjalnych przyczyn zapalenia nerwu wzrokowego, w tym:
Idiopatyczne zapalenie nerwu wzrokowego
Wiele przypadków zapalenia nerwu wzrokowego jest idiopatycznych, co oznacza, że nie mają znanej przyczyny.78 Szacuje się, że około połowa początkowych przypadków zapalenia nerwu wzrokowego ma niewykrywalną przyczynę i jest opisywana jako idiopatyczna.79
Niedobory witamin
Niedobór witaminy B12 został powiązany z zapaleniem nerwu wzrokowego. Ta forma zapalenia nerwu wzrokowego jest odwracalna i poddaje się leczeniu.80
Niedokrwienie
Brak przepływu krwi (niedokrwienie) do nerwu wzrokowego może powodować nieprawidłowe funkcjonowanie jego komórek, prowadząc do uszkodzenia nerwu wzrokowego.81
Po szczepieniach
Zapalenie nerwu wzrokowego może wystąpić w wyniku odpowiedzi immunologicznej po szczepieniach, na przykład przeciwko odrze i różyczce.8283
Ucisk i naciekanie
Inne etiologie związane z zapaleniem nerwu wzrokowego obejmują wady wrodzone, jaskrę, podwyższone ciśnienie wewnątrzczaszkowe (tj. obrzęk tarczy), ucisk, neuropatię toksyczną i odżywczą nerwu wzrokowego, uraz, dziedziczną neuropatię nerwu wzrokowego lub naciekanie (np. nowotworowe lub ziarniniakowe).84
Czynniki ryzyka zapalenia nerwu wzrokowego
Czynniki ryzyka typowego i atypowego zapalenia nerwu wzrokowego obejmują wiek, płeć, pochodzenie etniczne i czynniki genetyczne.85
Do znanych czynników ryzyka zapalenia nerwu wzrokowego należą:
- Wiek – Zapalenie nerwu wzrokowego występuje najczęściej u dorosłych poniżej 45 roku życia i częściej dotyka kobiety niż mężczyzn. Zapalenie nerwu wzrokowego jest bardziej prawdopodobne u osób w wieku od 20 do 40 lat.8687
- Płeć – Zapalenie nerwu wzrokowego jest około dwa razy bardziej prawdopodobne u kobiet niż u mężczyzn.88
- Pochodzenie etniczne – Osoby rasy kaukaskiej są bardziej narażone na rozwój zapalenia nerwu wzrokowego niż inne grupy etniczne.89
- Osobista lub rodzinna historia stwardnienia rozsianego lub innych chorób autoimmunologicznych90
- Wcześniejsza historia zapalenia nerwu wzrokowego91
- Wcześniejsza historia poprzecznego zapalenia rdzenia kręgowego (zapalenie rdzenia kręgowego)92
- Miejsce zamieszkania – Życie w regionie o dużej wysokości nad poziomem morza93
- Określone mutacje genetyczne94
Geopopulacyjne aspekty zapalenia nerwu wzrokowego
Częstość występowania zapalenia nerwu wzrokowego jest najwyższa w populacjach położonych na wyższych szerokościach geograficznych, w północnych Stanach Zjednoczonych i Europie Zachodniej, a najniższa w regionach bliższych równikowi. W Stanach Zjednoczonych badania oszacowały roczną zapadalność na zapalenie nerwu wzrokowego na poziomie 6,4 na 100 000. W Stanach Zjednoczonych zapalenie nerwu wzrokowego występuje częściej u osób rasy białej w porównaniu z Afroamerykanami. W Azji zapalenie nerwu wzrokowego jest proporcjonalnie częstsze w stosunku do częstości występowania stwardnienia rozsianego (SM) niż w Stanach Zjednoczonych czy Europie Zachodniej.95
Różnica w wynikach zapalenia nerwu wzrokowego między Zachodem a Wschodem wynika ze zwiększonej częstości występowania atypowego zapalenia nerwu wzrokowego i prawdopodobnie etnicznej różnicy w przebiegu choroby.96
Podsumowanie etiologii zapalenia nerwu wzrokowego
Zapalenie nerwu wzrokowego jest wieloczynnikowym stanem, z autoimmunologicznymi, zakaźnymi, toksycznymi i idiopatycznymi mechanizmami potencjalnie przyczyniającymi się do jego rozwoju.97
Chociaż dokładny przebieg zapalenia nerwu wzrokowego nie jest w pełni poznany, mechanizm autoimmunologiczny, w którym układ odpornościowy błędnie atakuje mielinę otaczającą nerw wzrokowy, jest uważany za główną przyczynę. Stwardnienie rozsiane pozostaje najczęstszą zidentyfikowaną przyczyną, ale szeroki zakres innych stanów – od chorób autoimmunologicznych przez zakażenia po toksyny i leki – może również prowadzić do rozwoju tego schorzenia.
Zrozumienie różnych etiologii zapalenia nerwu wzrokowego jest kluczowe dla właściwej diagnozy i leczenia, ponieważ różne przyczyny mogą wymagać różnych podejść terapeutycznych i mogą wiązać się z różnymi rokowaniami dla pacjenta.

Optic neuritis occurs when swelling (inflammation) damages the optic nerve a bundle of nerve fibers that transmits visual information from your eye to your brain. […] The exact cause of optic neuritis is unknown. It’s believed to develop when the immune system mistakenly targets the substance covering your optic nerve, resulting in inflammation and damage to the myelin. […] Besides MS, optic nerve inflammation can occur with other conditions, including infections or immune diseases, such as lupus. Rarely, another disease called neuromyelitis optica causes inflammation of the optic nerve and spinal cord. […] The following autoimmune conditions often are associated with optic neuritis: Multiple sclerosis. Multiple sclerosis is a disease in which your autoimmune system attacks the myelin sheath covering nerve fibers in your brain.
- #2 Optic Neuritis – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK557853/
The mechanism responsible for acute optic neuritis has not been definitively identified. However, an autoimmune reaction damaging the myelin sheath surrounding neurons within the optic nerve is considered a primary factor. Patients with documented autoimmune diseases have a greater propensity to develop optic neuritis, and a causal relationship between HLA DRB1, HLA-B27, and this condition has been observed. […] Some studies suggest that viral illnesses, known to precipitate autoimmune reactions, may induce optic neuritis attacks. Optic neuritis may manifest as a demyelinating disease affecting several central nervous system areas. Optic neuritis is often the first clinical manifestation of demyelination. […] The condition is multifactorial, with autoimmune, infectious, toxic, and idiopathic mechanisms potentially contributing to its development.

Most cases of optic neuritis (ON) are associated with multiple sclerosis (MS), even though ON can occur in isolation. In MS-associated and isolated monosymptomatic ON, the cause is presumed to be an autoimmune reaction that results in a demyelinating inflammation of the nerve. Pathologic studies in patients with ON associated with MS have shown that the demyelinated lesions in the optic nerve are similar to the MS plaques seen in the brain, with an inflammatory response marked by perivascular cuffing, T cells, and plasma cells. However, little is known about the pathology of isolated ON. […] In a single case of chronic, isolated ON, a biopsy specimen showed the presence of perivascular lymphocytic infiltration, multifocal demyelination, and reactive astrocytosis in the retrobulbar portion of the optic nerve. Abnormal intrathecal IgG synthesis, reflected as the presence of oligoclonal bands in the cerebrospinal fluid (CSF), is found in 60-70% of patients with isolated ON, suggesting an immunologic etiology similar to that of MS.

- #7 Optic neuritis – Wikipediahttps://en.wikipedia.org/wiki/Optic_neuritis
Optic neuritis may be a result of standalone idiopathic disease, but is often a manifestation that occurs secondary to an underlying disease. […] The most commonly considered etiologies are multiple sclerosis (MS), neuromyelitis optica (NMO) / neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein-antibody-associated disease (MOGAD). […] Other etiologies include idiopathic ON, infections (eg, syphilis, Lyme disease, and viral infections such as herpes simplex and varicella-zoster), and systemic autoimmune diseases (eg, systemic lupus erythematosus and sarcoidosis). […] ON is classified as typical optic neuritis when demyelination is the causative pathophysiologic aberrancy. […] This classification attributes the manifestation of ON primarily to multiple sclerosis or standalone idiopathic disease, of which multiple sclerosis is the most common underlying etiology of all subtypes of optic neuritis.
- #8 Optic neuritis – Wikipediahttps://en.wikipedia.org/wiki/Optic_neuritis
Atypical ON is most frequently seen as an early manifestation of neuromyelitis optica spectrum disorder (NMOSD), formerly known as neuromyelitis optica (NMO). […] Other causes of atypical ON include myelin oligodendrocyte glycoprotein-antibody-associated disease (MOGAD), other autoimmune disorders (eg, Sarcoidosis, Sjogren syndrome, rheumatoid arthritis, systemic lupus erythematosus), and infections (Bacterial [Tuberculosis, syphillis, meningitis, Lymes disease, Bartonella] or Viral [measles, mumps, rubella, chicken pox, herpes]). […] A wide range of attributable infectious etiologies have been found to cause optic neuritis and can arise from varying pathophysiologic mechanisms. […] Other etiologies associated with optic neuritis include congenital anomalies, glaucoma, elevated intracranial pressure (i.e. papilledema), compression, nutritional and toxic optic neuropathy, trauma, inherited optic neuropathy, or infiltration (eg, neoplastic or granulomatous).

Optic neuritis, or inflammation of the optic nerves, is a frequent cause of acute optic nerve injury in children and adults. Although optic neuritis is frequently associated with multiple sclerosis, there are many other causes of optic neuritis. […] Demyelinating disorders are a common cause of ON in parts of the world where multiple sclerosis (MS) is common such as northern European countries. Multiple sclerosis associated optic neuritis as the first presentation of a clinical isolated syndrome with MRI or CSF findings compatible with multiple sclerosis. It can also occur as a multiple sclerosis relapse. Isolated MS-ON is an atypical or attenuated manifestation of multiple sclerosis. There are many other possible causes of optic neuritis which must not be overlooked, as they may require different and urgent management.

- #12 Optic neuritis: Pathophysiology, clinical features, and diagnosis – UpToDatehttps://www.uptodate.com/contents/optic-neuritis-pathophysiology-clinical-features-and-diagnosis
Optic neuritis is an inflammatory, demyelinating condition that causes acute, usually monocular, visual loss. It is highly associated with multiple sclerosis (MS). Optic neuritis is the presenting feature of MS in 15 to 20 percent of patients and occurs in 50 percent at some time during the course of their illness. […] The term „optic neuritis” is sometimes applied to other inflammatory and infectious conditions affecting the optic nerve. These and other causes of optic neuropathy are discussed separately. […] The incidence of optic neuritis is highest in populations located at higher latitudes, in the northern United States and western Europe, and is lowest in regions closer to the equator. In the United States, studies have estimated the annual incidence of optic neuritis to be as high as 6.4 per 100,000. In the United States, optic neuritis occurs more frequently in White compared with Black Americans. In Asia, optic neuritis is proportionately more common relative to the incidence of multiple sclerosis (MS) than in the United States or Western Europe.

Neuromyelitis optica (NMO) has been recognized as a distinct inflammatory demyelinating disease consisting of ON in combination with longitudinally extensive transverse myelitis. Neuromyelitis optica is associated with the presence of a specific serum, NMO IgG autoantibody, which targets the water channel aquaporin-4. […] Approximately two thirds or more of patients with neuromyelitis optica spectrum disorder (NMOSD) have IgG antibodies to aquaporin-4 (AQP4-IgG), a water channel protein that is abundant on astrocytic membranes and proximate to the blood-brain barrier. Patients who are seronegative cannot be distinguished clinically from those who are seropositive. In AQP4-IgG-seropositive disease, binding of AQP4-IgG to AQP4 on astrocytic end-feet initiates the activation of the complement cascade, the infiltration of granulocytes into the central nervous system, and antibody-dependent cell-mediated cytotoxicity. […] As previously stated, ON can occasionally result from an infectious process involving the orbits or paranasal sinuses or occur in the course of a systemic viral infection.

ON is mainly idiopathic in nature; though, it could be related to demyelinating lesions (e.g. MS [4,8-10] neuromyelitis optica (NMO) [4,8,9]) or other less common etiologies such as autoimmune disease (e.g. sarcoidosis [1,4,9], systemic lupus erythematosus (SLE) [4,9]), infectious and para-infectious causes (e.g. syphilis [1,4,9,11], tuberculosis [4,9,11]), inflammatory and post vaccination immunological responses [4] (e.g. sinusitis [1], and vaccinations against measles and rubella [12]). […] The pathogenesis of optic neuritis is not well understood. It is likely due to some inflammatory process which leads to delayed type IV hypersensitivity reaction induced by released cytokines and other inflammatory mediators from activated peripheral T-cells which can cross the blood brain barrier and cause destruction of myelin, neural cell death and axonal degeneration. […] The presence of demyelinating white matter lesions in brain MRI scans, 3 mm or larger in diameter, ovoid, located in periventricular areas of the white matter and radiating toward the ventricular spaces has been identified as the strongest predictor for the development of MS.

Optic neuritis is a condition with close links to multiple sclerosis (MS), an illness that causes inflammation and damage to nerves in the brain and spinal cord. It is often one of the first symptoms of MS. […] Scientists do not know the exact cause of optic neuritis. One theory is that it develops when the immune system which usually fights infection by attacking bacteria, viruses, and other foreign proteins targets the myelin sheath instead. […] People with autoimmune diseases, particularly MS, are more likely to get optic neuritis. According to a 2023 article, optic neuritis is an early symptom in around 15-20% of people with MS. […] Some evidence also suggests that viral illnesses can cause bouts of optic neuritis, as viral infections can sometimes cause an autoimmune response. […] Some risk factors for optic neuritis include: Age: Optic neuritis is more likely to happen in those ages 20 to 40 years.

Optic neuritis is a condition with close links to multiple sclerosis (MS), an illness that causes inflammation and damage to nerves in the brain and spinal cord. It is often one of the first symptoms of MS. […] Scientists do not know the exact cause of optic neuritis. One theory is that it develops when the immune system which usually fights infection by attacking bacteria, viruses, and other foreign proteins targets the myelin sheath instead. […] People with autoimmune diseases, particularly MS, are more likely to get optic neuritis. According to a 2023 article, optic neuritis is an early symptom in around 15-20% of people with MS. […] Some evidence also suggests that viral illnesses can cause bouts of optic neuritis, as viral infections can sometimes cause an autoimmune response. […] Some risk factors for optic neuritis include: Age: Optic neuritis is more likely to happen in those ages 20 to 40 years. […] Optic neuritis is around twice as likely to happen in females than in males. […] Caucasian people are more likely to develop optic neuritis than other ethnicities.

Optic neuritis (ON) occurs when the optic nerve becomes inflamed. […] In most cases, the exact cause of ON isn’t fully understood. However, several factors can lead to inflammation. […] For example, your own immune system can attack itself through an autoimmune disease, like MS. This causes your body to mistakenly attack the protective coating of the optic nerve. […] It can also be caused by viral infections such as measles, mumps, or herpes. These conditions can trigger an immune response, which can damage the optic nerve. Meanwhile, bacterial infections such as Lyme disease, syphilis, and tuberculosis have also been associated with optic neuritis. […] Other risks include: Aged between 20 to 40 years, Have multiple sclerosis, Live in a high-altitude area, Have certain genetic mutations.

Optic neuritis is an inflammatory, demyelinating condition that causes acute, usually monocular, visual loss. It is highly associated with multiple sclerosis (MS). Optic neuritis is the presenting feature of MS in 15 to 20 percent of patients and occurs in 50 percent at some time during the course of their illness. […] The term „optic neuritis” is sometimes applied to other inflammatory and infectious conditions affecting the optic nerve. These and other causes of optic neuropathy are discussed separately. […] The incidence of optic neuritis is highest in populations located at higher latitudes, in the northern United States and western Europe, and is lowest in regions closer to the equator. In the United States, studies have estimated the annual incidence of optic neuritis to be as high as 6.4 per 100,000. In the United States, optic neuritis occurs more frequently in White compared with Black Americans. In Asia, optic neuritis is proportionately more common relative to the incidence of multiple sclerosis (MS) than in the United States or Western Europe.

The disparity in optic neuritis outcome between the West and the East was due to the increased prevalence of atypical optic neuritis and likely an ethnic variation in the course of the disease. […] The discovery of NMO-IgG and AQP4 as its targeted antigen unequivocally confirmed neuromyelitis optica as a disease distinct from MS, and allowed its early laboratory recognition. […] AQP4 is a water-channel protein expressed in the brain, spinal cord, and optic nerves that are affected by NMO. […] In NMOSD, optic neuritis is characterized by more severe onset visual loss, bilateral optic nerve or optic chiasma involvement, relapse, poor response to IV corticosteroid pulses, poor recovery with permanent visual deficits, and association with normal brain MRI, or unspecific brain MRI lesions. […] The etiology of atypical ON varies widely and calls out for different treatment options.

The mechanism responsible for acute optic neuritis has not been definitively identified. However, an autoimmune reaction damaging the myelin sheath surrounding neurons within the optic nerve is considered a primary factor. Patients with documented autoimmune diseases have a greater propensity to develop optic neuritis, and a causal relationship between HLA DRB1, HLA-B27, and this condition has been observed. […] Some studies suggest that viral illnesses, known to precipitate autoimmune reactions, may induce optic neuritis attacks. Optic neuritis may manifest as a demyelinating disease affecting several central nervous system areas. Optic neuritis is often the first clinical manifestation of demyelination. […] The condition is multifactorial, with autoimmune, infectious, toxic, and idiopathic mechanisms potentially contributing to its development.
