Fig. 72. Traumatic cataract. A. Rosette traumatic cataract may in the anterior or posterior cortex or both. B. The slit lamp localized traumatic opacity in both the anterior and posterior cortex in this case. C. One of the most reliable signs of traumatic cataract is alteration of retinoscopy. D. Histologically cortical degeneration and bladder cell formation is responsible for the opacity seen clinically. The nucleated cells (arrows) have a superficial resemblance to the urothelium of the bladder. (Hematoxylin-eosin stain; × 101.)
