Diskromatopsi, Akromatopsi ve Mavi Kon Monokromatizmi; Patofizyoloji, Klinik Bulgular, Tanı ve Tedavi

Renkli görme, retinadaki koni fotoreseptörlerinin uyarılması ve bu uyarının beyinde algılanması ile oluşan karmaşık bir algıdır. Kalıtsal renkli görme kusurları koni hücrelerinin fonksiyonlarındaki bozukluk sonucu oluşur. Renkli görme bozuklukları konilerin içerdiği üç farklı pigment tipine göre adlandırılır. Dünya genelinde yüksek prevalansta görülen bu bozukluklar, erkeklerde daha sık saptanmaktadır. Düşünülenin aksine renkli görme kusurları günlük hayatı sıklıkla etkiler. Tanı renkli görme testleri ve elektrofizyolojik testler ile kolaylıkla konabilmekle beraber günümüzde tedavi seçenekleri sınırlı ve başarı oranı düşüktür.

Dyschromatopsy, Achromatopsia and Blue Cone Monochromatism; Pathophysiology, Clinical Findings, Diagnosis and Treatmentand Treatment

Color vision is a complex perception caused by the stimulation of cone photoreceptors in the retina and the perception of this stimulation in the brain. Hereditary color vision deficiencies are caused by a defect in the functions of cone cells. Color vision deficiencies are named according to three different types of pigments contained in cones. These disorders, which are seen in high prevalence in worldwide, are found more frequently in male. Contrary to thought, colored vision defects often affect daily life. Although it can be easily diagnosed with color vision tests and electrophysiological tests, current treatment options are limited and its success rate is low.
