Gonioscopy of the right eye showing occludable angles with bumpy appearance of the peripheral iris (arrows). Note that the goniopictures shown have been taken under bright light to demonstrate the bumpy appearance of the iris, and does not refect the extent of closure seen with a narrow slit-lamp beam (center). UBM picture showing iridociliary cyst

The peripheral iris had a 'bumpy' appearance suggesting iridociliary cysts or plateau iris configuration (Fig. 1). Iridociliary cysts in the right eye were confirmed by ultrasound biomicroscopy (UBM) (Fig. 1).
(A) Deeply excavated optic disk, superotemporal retinal detachment (white arrows) and ILM folds (black arrows). (B) Normal left eye. (C and D) FFA showing persistent staining of the temporal disk area suggestive of a pit

Posterior segment evaluation of the right eye revealed cup-disk ratio 0.9 with a deeply excavated cup (Fig. 2A). The left eye was normal (Fig. 2B). Fundus fluorescein angiography of the right eye showed persistent staining of the optic disk in the late phase localized to one area (Figs 2C and D), suggestive of an optic disk pit, but it was not evident clinically.
(A) advanced visual field defect in the right eye. (B) Normal visual fields in the left eye. (C) Stratus and (D) Cirrus OCT scan through the suspected area showing excavation in the lamina cribrosa and serous macular detachment

Visual fields showed advanced glaucomatous damage in the right eye and were normal in the left (Figs 3A and B). Time-domain optical coherence tomography (Stratus OCT) (Fig. 3C) showed an excavation in the lamina cribrosa suggestive of an optic disk pit. Findings on the spectral-domain OCT (Cirrus OCT) (Fig. 3D) were similar and no conduit could be detected.
