Ślepota barw (zaburzenia widzenia barw)
Rokowania, prognozy i postęp choroby
Ślepota barw, czyli zaburzenia widzenia barw (colour vision deficiency), wynikają z nieprawidłowego funkcjonowania lub braku czopków w siatkówce, najczęściej dotyczą defektów widzenia czerwono-zielonego. Zaburzenia te są przeważnie dziedziczne i nie podlegają obecnie leczeniu, choć rokowanie jest dobre, gdyż pacjenci adaptują się do schorzenia. Łagodne formy mają minimalny wpływ na codzienne funkcjonowanie, natomiast cięższe mogą wymagać wsparcia edukacyjnego u dzieci oraz ograniczać wybór zawodów u dorosłych, zwłaszcza tych wymagających precyzyjnego rozróżniania kolorów, takich jak pilot, maszynista czy grafik. Monochromatyzm czopków niebieskich, związany z mutacjami genów OPN1LW i OPN1MW, prowadzi do poważnego ograniczenia widzenia barw i ostrości wzroku.

Ślepota barw (zaburzenia widzenia barw) – definicja
Ślepota barw, określana również jako zaburzenia widzenia barw (ang. colour vision deficiency), to stan, w którym osoba dotknięta tym schorzeniem postrzega kolory inaczej niż większość ludzi i ma trudności z rozróżnianiem kolorów.1 Zaburzenie to występuje, gdy czopki (rodzaj komórek nerwowych w siatkówce oka) nie funkcjonują prawidłowo lub są nieobecne.2 Ślepota barw może objawiać się w różnym stopniu nasilenia – od łagodnego do ciężkiego, gdzie najczęstszą formą są defekty widzenia czerwono-zielonego.3
Rokowanie dla pacjentów z wrodzonymi zaburzeniami widzenia barw
Większość osób cierpiących na zaburzenia widzenia barw rodzi się z tą przypadłością, ponieważ najczęstsze typy są dziedziczne – przekazywane przez rodziców.4 Obecnie nie istnieje leczenie ani kuracja dla osób z dziedziczną ślepotą barw.56 Pomimo braku leczenia, rokowanie dla pacjentów z wrodzonymi zaburzeniami widzenia barw jest generalnie dobre, ponieważ większość osób dobrze adaptuje się do życia z tym schorzeniem.7
Adaptacja do życia z zaburzeniami widzenia barw
Osoby cierpiące na dziedziczne zaburzenia percepcji kolorów często zauważają je dopiero po wielu latach życia z tym stanem.8 Łagodna forma zaburzeń widzenia barw może mieć bardzo niewielki wpływ na życie lub nie mieć go wcale.9 Większość osób z czasem przystosowuje się do innego widzenia kolorów.10
Wpływ na dzieci w wieku szkolnym
Dzieci z zaburzeniami widzenia barw mogą potrzebować pomocy przy niektórych aktywnościach szkolnych.11 Zaburzenia widzenia barw mogą wpływać na wyniki szkolne dziecka.12 Ważne jest, aby rozmawiać ze specjalistą okulistycznym (optometrystą lub okulistą) o charakterze schorzenia i jego potencjalnym wpływie na edukację.13
Ograniczenia zawodowe i wpływ na życie dorosłych
Dorośli z zaburzeniami widzenia barw mogą potrzebować dostosowań do wykonywania zawodów, które opierają się na rozróżnianiu kolorów, takich jak grafik.14 Posiadanie zaburzeń widzenia barw może oznaczać, że niektóre kariery są niedostępne ze względów bezpieczeństwa.15
Zawody wymagające prawidłowego widzenia barw
Wiele zawodów wymaga doskonałego widzenia barw i nie akceptuje osób niewidzących kolorów lub z deficytami percepcji kolorów.16 Do zawodów, które mogą być zbyt wymagające lub niebezpieczne do wykonywania przy zaburzeniach widzenia barw, należą:
- Pilot
- Maszynista
- Elektryk
- Projektant mody
- Grafik
Osoby z zaburzeniami widzenia barw mogą jednak realizować się w innych karierach, gdzie widzenie kolorów nie odgrywa głównej roli.19
Wpływ psychologiczny
Jeśli zaburzenia widzenia barw zakłócają zdolność do realizacji celów życiowych, pacjenci mogą odczuwać smutek lub rozczarowanie.20 Bardziej nasilone formy mogą ingerować w życie zawodowe, edukacyjne lub osobiste.21
Rokowanie dla różnych typów zaburzeń widzenia barw
Zaburzenia czerwono-zielone
Defekty widzenia czerwono-zielonego są najczęstszą formą zaburzeń widzenia barw. Dotknięte osoby mają problemy z rozróżnianiem niektórych odcieni czerwieni, żółci i zieleni.22 Obecnie nie ma leczenia dla żadnej formy deficytu czerwono-zielonego.23
Monochromatyzm czopków niebieskich
Rzadszą i bardziej poważną formą zaburzeń widzenia barw jest monochromatyzm czopków niebieskich, który powoduje bardzo słabą ostrość wzroku i poważnie ograniczone widzenie kolorów.24 Monochromatyzm czopków niebieskich występuje, gdy zmiany genetyczne wpływające na geny OPN1LW i OPN1MW uniemożliwiają prawidłowe funkcjonowanie zarówno czopków L, jak i M. U osób z tym schorzeniem funkcjonują tylko czopki S, co prowadzi do zmniejszonej ostrości wzroku i słabego widzenia kolorów.25
Całkowita ślepota barw
Całkowita ślepota barw jest zwykle dziedziczna, ale może również wynikać z cerebralnej achromatopsji po udarze, traumatycznym urazie mózgu lub innych formach uszkodzenia mózgu.26 Przy całkowitej ślepocie barw rokowanie zależy od przyczyny – w przypadkach dziedzicznych stan pozostaje stabilny, natomiast w przypadkach nabytych na skutek uszkodzenia mózgu rokowanie zależy od możliwości regeneracji tkanki nerwowej.
Nabyte zaburzenia widzenia barw
Nie wszystkie problemy z widzeniem kolorów są spowodowane mutacjami genów. Te niedziedziczne stany są opisywane jako nabyte zaburzenia widzenia barw.27 Jeśli masz nabyty deficyt widzenia barw, twój lekarz będzie leczyć chorobę podstawową lub dostosuje leki według potrzeby. Może to pomóc w poprawie widzenia kolorów.28
Perspektywy terapeutyczne w przyszłości
Badania naukowe sugerują, że terapie genowe (leczenie zmieniające geny w docelowej lokalizacji) są obiecujące dla ciężkiego typu zaburzeń widzenia barw.29 Choć obecnie nie ma kuracji dla dziedzicznych zaburzeń widzenia barw, postęp w dziedzinie terapii genowej może w przyszłości przynieść nowe możliwości leczenia.
Podsumowanie rokowania
Ślepota barw to powszechny stan, który występuje w różnym nasileniu od łagodnego do ciężkiego.30 Mimo braku leczenia dla dziedzicznych form zaburzeń widzenia barw, większość osób dobrze adaptuje się do życia z tym schorzeniem. Łagodna forma może mieć bardzo niewielki wpływ na życie lub nie mieć go wcale, podczas gdy cięższe formy mogą wymagać dostosowań w edukacji i ograniczać wybór kariery zawodowej. Nabyte zaburzenia widzenia barw mogą poprawić się po leczeniu choroby podstawowej. Postęp w terapii genowej daje nadzieję na potencjalne leczenie w przyszłości dla niektórych form tego schorzenia.

Color blindness is when you dont see colors in the traditional way because some cones (nerve cells) in your eyes are missing or dont work correctly. Color blindness (color vision deficiency) is a fairly common condition in which you dont see colors in the traditional way. This happens when cones (a type of nerve cell in your eye retina) arent working correctly. For most people, color blindness is inherited. That means its passed down from your biological parents from the mother in the most common red-green forms of color blindness. If you or your child has color blindness, its important to learn the type and severity. Talk to an eye care provider (optometrist or ophthalmologist) about the nature of the condition and how it may affect you. Currently, theres no medical treatment or cure for people with inherited color blindness. If you have acquired color blindness, your healthcare provider will treat the underlying condition or adjust your medications as needed. This may help improve your color vision. Color blindness might not affect your life much, especially if your condition is mild. More severe forms may interfere with your job, education or personal life. Its important to talk to your eye care provider about your condition and what you can expect going forward. Certain careers may be too challenging or unsafe to pursue with color deficiency. These include careers as an electrician, pilot, fashion designer or graphic artist. But you can encourage your child to pursue other careers where color vision wont play a major role. Color blindness is a common condition that ranges from mild to severe. A mild form may impact your life very little, or not at all. But if color blindness interferes with your ability to pursue your goals, you may feel upset or disappointed.

Color vision deficiency (sometimes called color blindness) represents a group of conditions that affect the perception of color. Red-green color vision defects are the most common form of color vision deficiency. Affected individuals have trouble distinguishing between some shades of red, yellow, and green. […] A less common and more severe form of color vision deficiency called blue cone monochromacy causes very poor visual acuity and severely reduced color vision. […] Blue cone monochromacy occurs when genetic changes affecting the OPN1LW and OPN1MW genes prevent both L and M cones from functioning normally. In people with this condition, only S cones are functional, which leads to reduced visual acuity and poor color vision. […] Some problems with color vision are not caused by gene mutations. These nonhereditary conditions are described as acquired color vision deficiencies. […] Blue-yellow color vision defects are inherited in an autosomal dominant pattern, which means one copy of the altered OPN1SW gene in each cell is sufficient to cause the condition.

Color vision deficiency (sometimes called color blindness) represents a group of conditions that affect the perception of color. Red-green color vision defects are the most common form of color vision deficiency. Affected individuals have trouble distinguishing between some shades of red, yellow, and green. […] A less common and more severe form of color vision deficiency called blue cone monochromacy causes very poor visual acuity and severely reduced color vision. […] Blue cone monochromacy occurs when genetic changes affecting the OPN1LW and OPN1MW genes prevent both L and M cones from functioning normally. In people with this condition, only S cones are functional, which leads to reduced visual acuity and poor color vision. […] Some problems with color vision are not caused by gene mutations. These nonhereditary conditions are described as acquired color vision deficiencies. […] Blue-yellow color vision defects are inherited in an autosomal dominant pattern, which means one copy of the altered OPN1SW gene in each cell is sufficient to cause the condition.

Life is filled with a vast array of colors but not everyone perceives colors to the same degree: color blindness and red-green color deficiency are widespread visual impairments. And often those affected don’t even notice. […] People suffering from hereditary color perception difficulties often only notice after many years of living with this condition. […] Many professions require perfect color vision and do not accept color blind people or those with color perception deficiencies. […] There is no treatment for either form of red-green deficiency. […] Currently, there is no treatment for color blindness or a color deficiency. […] There is no treatment for partial color blindness. […] Complete color blindness is usually hereditary, but it can also result from cerebral achromatopsia following a stroke, a traumatic brain injury or other forms of brain damage.

Color blindness is when you dont see colors in the traditional way because some cones (nerve cells) in your eyes are missing or dont work correctly. Color blindness (color vision deficiency) is a fairly common condition in which you dont see colors in the traditional way. This happens when cones (a type of nerve cell in your eye retina) arent working correctly. For most people, color blindness is inherited. That means its passed down from your biological parents from the mother in the most common red-green forms of color blindness. If you or your child has color blindness, its important to learn the type and severity. Talk to an eye care provider (optometrist or ophthalmologist) about the nature of the condition and how it may affect you. Currently, theres no medical treatment or cure for people with inherited color blindness. If you have acquired color blindness, your healthcare provider will treat the underlying condition or adjust your medications as needed. This may help improve your color vision. Color blindness might not affect your life much, especially if your condition is mild. More severe forms may interfere with your job, education or personal life. Its important to talk to your eye care provider about your condition and what you can expect going forward. Certain careers may be too challenging or unsafe to pursue with color deficiency. These include careers as an electrician, pilot, fashion designer or graphic artist. But you can encourage your child to pursue other careers where color vision wont play a major role. Color blindness is a common condition that ranges from mild to severe. A mild form may impact your life very little, or not at all. But if color blindness interferes with your ability to pursue your goals, you may feel upset or disappointed.

If you have color blindness (color vision deficiency), it means you see colors differently than most people. […] Most people who have color vision deficiency are born with it. This is because the most common types of color vision deficiency are genetic, meaning theyâre passed down from parents. […] Thereâs no cure for color vision deficiency thatâs passed down in families (inherited), but most people adjust to it. Children with color vision deficiency may need help with some classroom activities, and adults with color vision deficiency may need accommodations to do jobs that rely on telling the difference between colors, like being a graphic designer. […] Research studies suggest that gene therapies (treatments that change genes in a target location) are promising for a severe type of color vision deficiency.
