چکیده
A 20-year-old white female, who is an avid tanning-bed user, was referred for the evaluation of a pigmented lesion in her left eye. She reported occasional lid swelling, pain, tearing and light sensitivity for two years, which she attributed to wearing contact lenses. The patient received a diagnosis of ocular melanosis 6 months prior to her current presentation. On examination, the best-corrected visual acuity (BCVA) of the left eye was 20/20, whose intraocular pressure (IOP) was 13 mmHg. Color vision, pupillary reaction, confrontational visual fields and extraocular muscle movement tests were within normal limits. Slit-lamp examination showed a deeply-pigmented velvety lesion covering the iris between 1 and 5 o'clock positions, suggesting diffuse iris nevus (Fig. 1A and B). The sclera showed a bluish hue consistent with ocular melanocytosis (Fig. 1C). Gonioscopy revealed an increased pigmentation of the angle. However, B-scan ultrasonography excluded the involvement of the posterior uvea or ciliary body. Examination of the right eye
