Dr., Elazığ Eğitim ve Araştırma Hastanesi, Göz Hastalıkları, Elazığ, Türkiye We aimed to report a rare case with the occult choroidal macrovessel (CM) detected by enhanced depth imaging (EDI) mode of spectral domain optical coherence tomography (OCT). The case is 12 years old girl regularly ongoing follow-ups in the retina section of our clinic for atypical retinitis pigmentosa. Her visual acuities were 1/10 in the right eye and 8/10 in the left eye. Biomicroscopical examination revealed aphakia, diffuse corneal opacity, pupillary irregularity and mild phitisis bulbi in the right eye. Any pathology in the biomicroscopy of the left eye was not observed. Fundus examination revealed widespread retina pigment epithelium (RPE) alterations in posterior pole in both eyes. Fundus fl uorescein angiography of the left eye showed widespread RPE window defects around optic disc and in the whole macula at all phases without any retinal vascular fi lling defect. EDI-OCT and enface-OCT revealed a worm-like or tubular choroidal hyporefl ective lesion beneath the fovea. The occult CM was diagnosed based on OCT fi ndings. EDI-OCT and en face OCT might reveal an occult CM in the patients which fundus angiography and examination could not show it.
