Abstract
Retina gözün ışığın zararlı etkilerine maruz kalan hassas bir tabakasıdır. Retinayı saran koroid dokusu ise retinanın dış ta- bakalarının beslenmesi dışında skleranın büyümesi, emetropizasyon ve vazomotor kontrol ile göziçi basıncın düzenlenmesi gibi görevler üstlenmiştir. Koroidin çoğu zaman gözardı edilen hayati görevlerinden biri de retina hasarlarını önlemedeki fonksiyonudur. Bu makale koroid tabakasının retinada oluşacak hasarı engelleme mekanizmalarını, retina üzerindeki ter- moregülatör görevini ve bu dokuda meydana gelen aksamalarla yaşa bağlı maküla dejeneresansı gibi başlıca hastalıkların gelişimi arasındaki ilişkiyi konu almıştır.
The retina is a sensitive layer of the eye that is exposed to harmful effects of light. Besides nourishing the outer layers of the retina, the choroid tissue has additional functions such as scleral growth, emmetropisation and the vasomotor control of intraocular pressure. One of the vital but mostly disregarded functions of the choroid is the prevention of retinal damage. This article discusses the retinal damage prevention mechanisms and the retinal thermoregulatory function of the choroid as well as the development of main pathologies such as age-related macular degeneration with choroidal dysfunction.
