Abstract

Objective: To compare macular and retinal nerve fiber layer thicknesses of the normal fellow eye to that of the amblyopic eye using optical coherence tomography in patients with anisometropic amblyopia.Methods and Material: 18 patients with anisometropic amblyopia were included. Patients were divided into two groups: nine hyperopic and nine myopic. Best corrected visual acuity, refraction, retinal nerve fiber layer and macular thicknesses were measured.Results: The mean macular thickness of all anisometropic patients was 195 (±20.8) µm and (171±45.8) µm, and the mean retinal nerve fiber layer thickness was 101.50 (±15.23) and 102.61 (±11.48), in the amblyopic eye and the normal eye, respectively. There was no significant difference between eyes in either macular or retinal nerve fiber layer thickness. Also there was no significant difference in two parameters in myopic and hyperopic group.Conclusions: No difference between the macular and retinal nerve fiber layer thicknesses was established in anisometropic amblyopia. Further evaluation is needed.

Abstract

AMAÇ: Anizometropik ambliyopi hastalarının makula kalınlıklarının ve retina sinir lifi tabaka kalınlıklarının optik koherens tomografi ile ölçülen değerlerinin sağlam gözleri ile ambliyop gözleri arasında değerlendirilmesiGereç ve Yöntemler: Çalışmaya 18 anizometropik ambliyopi hastası dahil edildi ve hastalar 9 hiperopik ve 9 miyopik olmak üzere iki gruba ayrıldı. Hastaların tamamında en iyi düzeltilmiş görme keskinliği, refraktometrik değerleri,retina sinir lifi tabaka kalınlığı ve makula kalınlığı optik koherens tomografi cihazı ile ölçüldü. Çalışma türü prospektif olup istatistiksel analiz için SPSS 11.0 software programı kullanıldı.Bulgular: Ortalama makula kalınlığı ambliyop gözlerde 195 (±20.8) µm ve sağlam gözlerde 171(±45.8) µm ölçülmüş olup ortalama retina sinir lifi tabaka kalınlığı ambliyop gözlerde 101.50 (±15.23) ve sağlam gözlerde 101.50 (±15.23) ölçüldü. Sağlam gözler ve ambliyop gözlerin makula kalınlığı ve retina sinir lifi tabaka kalınlığı arasında istatistiksel olarak anlamlı bir fark bulunmadı. Ayrıca hiperopik grup ile miyopik grup arasında da istatsitiksel olarak anlamlı bir fark tespit edilmedi. Sonuç: Ambliyopi göz küresinde herhangi bir organik patoloji olmadan görme keskinliğinin yeteri kadar gelişmemesi durumudur.Biz çalışmamızda 18 anizometropik ambliyop hastasının makula kalınlıkları ve retina sinir lifi tabaka kalınlıklarını ambliyop ve sağlam gözlerde karşılaştırdık. Hastaların sağlam gözleri ile ambliyop gözleri arasında istatistiksel olarak anlamlı bir fark bulamadık ama bu konuda daha fazla bilimsel çalışmaların yapılması gerektiğini düşünüyoruz.
