Özet

Bu vaka serisinde, vitreoretinal cerrahi sonrasında subfoveal perflorokarbon saptanan altı vakanın, klinik ve optik ko- horens tomografi (OKT) bulgularını sunmayı amaçladık. Görme azlığı şikayeti ile Retina birimine başvuran hastalarda regmatojen retina dekolmanı saptandı. Tüm olgulara, perflorokarbon kullanılarak vitreoretinal cerrahi uygulandı. Cerrahi sonrası dönemde tüm olgulara, oftalmik muayeneye ilaveten OKT, bazı olgulara ise fundus otofloresans (FAF) görüntüle- meleri yapıldı. Cerrahi sonrasında olguların hepsinde, subfoveal perflorokarbon klinik olarak tespit edildi. Aynı zamanda OKT ile hiporeflektif uniform, yuvarlak kabarcıklar, FAF ile ise kendisi hipo, etrafı hiperotofloresans kabarcıklar izlendi. Sonuç olarak, OKT ve fundus otofloresans, retina pigment epiteli atrofisine yol açabilen subfoveal perflorokarbon teşhisinde klinik incelemelere yardımcı yöntemlerdir.

Abstract

Our aim in this case series was to report and discuss the clinical and optical coherence tomography (OCT) findings of six eyes of six cases with retained subfoveal perfluorocarbon (PFC) bubbles after vitreoretinal surgery. The six cases were referred to the retina department of our hospital for decreased visual acuity related to rhegmatogenous retinal detachment and underwent vitreoretinal surgery with PFC. In addition to the ophthalmological examinations, OCT in all and fundus autofluorescence (FAF) findings in some cases were also evaluated in the postoperative period. Retained subfoveal PFC bubbles were detected clinically in all eyes. OCT showed hyporeflective, homogenous round bubbles while FAF showed hypofluorescent bubbles with a hyperfluorescent surrounding area. It was concluded that OCT and fundus autofluorescence could support clinical observations for the diagnosis of retained subfoveal PFC bubbles that may cause retinal pigment epithelium (RPE) atrophy.
