Pigment sheet on lens surface
A 5-year-old boy was detected to have low vision in left eye during his school eye check up. On examination, best corrected visual acuity was 20/20 and 20/80 in right and left eye, respectively. The intraocular pressure was 18 mmHg. Slit lamp examination revealed iris brown color pigmentation on anterior lens surface in left eye. On higher magnification, a layer of brown pigmented cells (clinically suggestive of melanocytes) arranged in whorls like pattern were noted [Fig. 1]. Anterior chamber was quiet. Fundus was normal. Usually, this pattern of pigmentation is described as remnant of persistent pupillary membrane and may require surgical intervention to prevent amblyopia.
