[Unilateral hemiarcus lipoides corneae inferior].

We document a case of unilateral hemiarcus lipoides, which developed de novo 10 months after trabeculectomy in the left eye of a 54-year-old woman. The involved eye showed heterochromia complicata Fuchs and had undergone intracapsular cataract extraction 11 years and trabeculectomy one year earlier. Except for intermittent hypercholesterolemia, the patient did not present any signs of systemic disease. The possible roles of relative ocular hypotony and modified aqueous circulation after trabeculectomy in the development of unilateral hemiarcus lipoides are discussed.
