Abstract

Retina is the neuronal layer in which images of the objects focus on and reach the visual center of the brain, occipital cortex, via neurons emanating from photoreceptor layer of retina. Retina is consisting of neurosensory retina and retina pigment epithelium(RPE). Having most important duties for the retina functions, RPE is settle on Bruch membran that lye above the choriocapillaris and has weak regenerative capability. Each retinal layer may present a different importance for the pathological situations like glaucoma and retinal diseases or electrophysiological tests. Important retinal anatomic structures have been aimed to be given briefly in this review article

Retina Anatomisi

Abstract

Retina objelerin görüntülerinin odaklandığı sinir tabakası olup buradan kalkan nöronlar beynin görme tabakası olan oksipital kortekse kadar giderler. Retina nörosensöriyel tabaka ve retina pigment epitelinden oluşur. Retina pigment epiteli koryokapillaris tabakasının üstünde bulunan Bruch membranı üzerinde yerleşik olup, rejenere olma kapasitesi zayıftır ve retinanın fonksiyonel işleyişi için çok önemli görevleri vardır. Glokom, retinal hastalıklar ve elektrofizyolojik testler açısından her tabakanın önemi bulunmaktadır. Makalede retinanın önemli anatomik yapıları ile ilgili bilgilerin öz olarak verilmesi amaçlanmıştır
