Transient cataract and hypermetropization in diabetes mellitus: case report.

A 13-year-old male patient with a recent history of hyperglycemia developed an acute bilateral posterior subcapsular cataract, consisting of fine feathery streak-like opacities. On examination, his uncorrected visual acuity was 20/50 and J4 at near in both eyes. Under cycloplegia, a moderate hypermetropic refraction was noted in both eyes. He was diagnosed with acute posterior subcapsular cataract secondary to diabetes mellitus. Two weeks after resolution of the hyperglycemic state, the bilateral feathery streak-like posterior subcapsular opacities regressed completely, hypermetropic refraction decreased and uncorrected visual acuity improved to 20/20 and J1 in both eyes.
