Retinal Pigment Epithelial Tears after Ex-PRESS Filtration Surgery in a Glaucoma Patient with a History of Ischemic Optic Neuropathy

Figure 1

Findings at the initial presentation of the patient. Color fundus photograph showed slightly paled optic disc and large cupping of optic disc (a). Vertical scan of optical coherence tomography (OCT) showed normal findings without any pigment epithelial detachment (PED) and choroidal neovascularization (b). OCT imaging of the circumpapillary retinal nerve fiber layer (cpRNFL) deviation map in the right eye showing thinning of the cpRNFL on both the superior and inferior sides (c). Fluorescein angiography showed partial delayed filling in the optic disc at superior and nasal side (arrowhead) (d) and delayed filling of the choroidal perfusion around the nasal-inferior region, including near the optic disc (arrow) (e). A Humphrey visual field test performed at our hospital one month after the initial visit revealed a severe visual field defect (g) that was much worse than the result observed at the previous hospital nine months earlier (f).
