Abstract

Delayed suprachoroidal hemorrhage (DSCH) is a rare but devastating complication of trabeculectomy, usually resulting in a poor visual prognosis. The typical presentation of DSCH includes acute visual loss, high intraocular pressure, a shallow anterior chamber, and choroidal elevation. We report a patient with hypertension who had DSCH following trabeculectomy, with an unusual presenting picture of a large blood clot hanging in a deep anterior chamber. Anterior chamber irrigation and choroidal taps were performed immediately. The intraocular pressure was soon controlled, and the visual acuity returned to 20/25 in 6 months.
