Abstract

A 37- year-old man applied to our outpatient clinic. The right eye showed nearly one disc diameter (DD) of round pale area inferior to the optic disc and bifurcated vessels arising from this area. B-scan ultrasonography, visual field analysis, fundus fluorescein angiography, and MRI were performed in order to confirm whether this formation is a true doubling of optic nerve or not. It is concluded that lesion is an isolated choroidal coloboma. Isolated choroidal coloboma is rare clinical entity. It may be confused true optic nerve duplication.

Özet

Otuz yedi yaşında erkek olgu rutin göz muayenesi için polikliniğimize baş vurdu. Sağ göz fundus muayenesinde, optik sinirin alt tarafında yaklaşık bir optik sinir büyüklüğünde yuvarlak, soluk retinal alan ve bu alanın merkezinde damar dallanmaları dikkati çekmekteydi. Bu oluşumun gerçek bir optik sinir çiftleşmesi olup olmadığını belirlemek için olgumuza B-scan ultrasonografi, bilgisayarlı görme alanı muayenesi, Manyetik rezonans görüntüleme (MRG) ve fundus floresein anjiografi (FFA) uygulandı. Olgumuz isole koroidal kolobom olarak değerlendirildi. İsole koroidal kolobomlar nadir görülen anomalilerdir. Görünümleri nedeni ile optik sinirin gerçek çiftleşmesi ile karıştırılabilirler.
