A 62-year-old lady presented to the clinic in September 2009 complaining of a 1-month history of decreased vision in the left eye with no associated pain or redness. On examination, the logMAR best-corrected visual acuity (BCVA) was −0.1 in the right eye (RE) and +0.5 in the left eye (LE). Slit-lamp examination of the LE revealed a subepithelial whitish flat lesion, 4 mm by 1.5 mm. This was surrounded by multiple well-defined translucent spots (figure 1). The corneal periphery showed a faint grey ring. The intraocular pressure was 16 mm Hg. Fundus examination was normal. The RE examination was unremarkable except for a faint grey ring at the corneal periphery.
