Fig. 30. A case of expulsive choroidal hemorrhage. A. Expulsive choroidal hemorrhage occurred 3 weeks after cataract surgery at the time when a limbal suture was removed. The intraocular pressure was reduced enough to allow shearing forces in the superficial choroid to tear an arteriole resulting in a high-pressure hemorrhage. B. In another case enucleated shortly after cataract extraction because of expulsive hemorrhage, accumulated blood can be identified in the suprachoroidal space. Because of the loose attachment of the choroid to the sclera, all intraocular contents were displaced toward the cataract wound. (Hematoxylin-eosin stain; × 3.) |
