title: Late hyphema due to wound vascularization.
abstract: In 1972 I reported that focal deep vascularization of the stromal wound may lead to hyphema months or years after cataract surgery. It results from ingrowth of episcleral vessels which terminate in capillaries at the inner edge of the incision site. Blurred vision occurring spontaneously or following minimal trauma, or physical strain is the primary symptom. Minimal episodes of bleeding are easily overlooked or mistaken for iridocyclitis. Gonioscopy usually reveals a small clump of vessels or the actual bleeding site. The trauma of the gonioscopy may precipitate bleeding.
