Abstract
Patients [14] with hereditary angioneurotic edema (Quincke edema) treated for an average period of 6 yr (ranging from 15 mo. to 8 yr) with tranexamic acid were given an ophthalmological examination to reveal any possible toxic damages due to treatment. As large doses of tranexamic acid given to animals cause retinal degeneration, the examination was focused on checking the retinal function. A complete ophthalmic examination revealed no toxic effects in the eyes of any of the patients. No retinal damages were found that could have been caused by the tranexamic acid. The central corneal thickness was normal.
