PURPOSE: To report a patient with retinal and choroidal vascular occlusion as a presenting sign of sickle cell trait following the development of aqueous misdirection syndrome. METHODS: Retrospective chart review. RESULTS: A patient treated for bilateral chronic angle-closure glaucoma with sequential EX-PRESS glaucoma filtration device surgery developed sequential bilateral aqueous misdirection syndrome. The left eye developed retinal arterial and localized choroidal vascular occlusions subsequent to an acute elevation in intraocular pressure and possibly the use of oral acetazolamide. The patient was subsequently found to have sickle cell trait. The right eye developed aqueous misdirection with acute elevation of intraocular pressure as well, but the patient was not treated with oral acetazolamide and did not develop vascular occlusion. CONCLUSION: Retinal and choroidal vascular occlusions can be the presenting sign of a patient with sickle cell trait. Sickle cell screening may be beneficial in African American or Middle Eastern patients after an acute rise in intraocular pressure, particularly before initiation of treatment with oral carbonic anhydrase inhibitors.
