Abstract

Purpose: To evaluate the photoreceptor layer status after antivascular endothelial growth factor (VEGF) therapy in choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) using spectral&#8211;domain optical coherence tomography (SD-OCT). Materials and Methods: Sixteen eyes of 16 patients with CNV secondary to AMD with foveal thickness less than 250 &#956; after treatment with anti-VEGF therapy and with no obvious leakage on SD-OCT, along with 10 healthy subjects as controls, were imaged with SD-OCT. The inner and outer segment (IS/OS) photoreceptor layers were graded, and correlated with various characteristics including visual acuity. Result: The IS/OS layer was detected in 6 (37%) eyes of patients with AMD and all eyes of the healthy control subjects (p<0.001). Eyes in patients with AMD with preserved IS/ OS had a significantly better BCVA and mean change in BCVA compared with eyes with absent IS/OS (p<0.01). Conclusions: SD-OCT is a useful tool to visualize IS/OS status. The IS/OS status after anti-VEGF therapy in AMD patients with CNV correlates with BCVA and mean change in BCVA.

Özet

Amaç: Bu çalışmanın amacı, yaşa bağlı maküla dejenerasyonuna (YBMD) sekonder koroid neovaskularizasyonu (KNV) nedeniyle intravitreal anti-vasküler endotelial büyüme faktörü (anti-VEGF) injeksiyon tedavisi uygulanan hastalardaki fotoreseptör tabakasının spektral domain optik koherens tomografi (SD-OKT) ile değerlendirilmesidir. Gereç ve Yöntem: Anti-VEGF tedavisini takiben son muayenelerinde SD-OKT incelemesinde retina içi ya da retina altı sıvıya rastlanmayan ve fovea kalınlıkları 250 mikronun altında olan 16 YBMD hastasının 16 gözü ile kontrol grubu olarak sağlıklı 10 birey SD-OKT ile görüntülendi. Fotoreseptör iç segment-dış segment tabakası derecelendirildi ve görme keskinliği ve diğer özellikleri açısından ilişkisi incelendi. Bulgular: Fotoreseptör bandı sağlıklı kontrol bireylerin gözlerinin tümünde, YBMD olgularının 6’sında (%37) fotoreseptör bandı izlendi p<0.001). Fotoreseptör bandı izlenen YBMD olgularının, izlenmeyen olgulara göre anlamlı seviyede daha iyi sonuç görme keskinliğine ve görme keskinliği artışına sahip olduğu tespit edildi (p<0.01). Sonuç: Spektal domain-OKT fotoreseptör iç segment dış segment bandını görüntülemede kullanılabilecek faydalı bir yöntemdir. Fotoreseptör iç segment dış segment durumu YBMD’na sekonder KNV nedeniyle intravitreal anti-VEGF injeksiyon tedavisi uygulananlarda tedavi sonrası görme keskinliği ve görmedeki ortalama değişim ile anlamlı düzeyde ilişkilidir.
