    A 47-year-old Hispanic patient presented with painless vision loss in his left eye over a period of two months. His visual acuity and intraocular pressure were normal, slit-lamp examination revealed a curvilinear dark lens opacity at the infero-nasal quadrant of the left eye (Figure 1), along with angle recession and dense pigment deposits (Figure 2). Dilated fundus examination showed rim thinning and sectoral nerve fiber layer loss superiorly, consistent with results from optical coherence tomography and visual field testing with VFI of 73%. Ultrasound biomicroscopy ruled out ciliary body mass in both eyes.
