Acute transient bilateral diabetic posterior subcapsular cataracts

A 62-year-old man in whom diabetes was recently detected presented with Vis ually significant, bilateral posterior subcapsular cataracts within days of initiating antihyperglycemic therapy. With efficient control and a stable serum glucose level, the cataracts started regressing. Except for a few sca ttered opacities, the patient was left with essentially clear lenses. Visua l acuity of counting fingers at 2 ft in the right eye and 20/63 in the left eye improved to 20/20 in both eyes within 5 weeks.
