1/8. Favorable outcome using a black diaphragm intraocular lens for traumatic aniridia with total iridectomy.A 25-year-old man had a penetrating injury to the left eye. Ocular examination revealed a full-thickness corneal laceration, total aniridia, anterior capsule rupture, and microscopic hyphema. Ten days after the immediate primary-repair surgery, aspiration of the lens secondary to traumatic cataract was performed. Four months later, a black diaphragm intraocular lens was implanted. Postoperatively, the best corrected visual acuity was 20/20 in both eyes. Multifocal spectacles were prescribed to provide the near and far vision required for the patient's job. Normal intraocular pressure and acceptable photophobia were noted during the 18-month follow-up.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
2/8. Medical and surgical management of spontaneous hyphaema secondary to immune thrombocytopenia.The medical and surgical management of an unusual case of spontaneous 'black ball' hyphaema complicated by secondary haemorrhage, raised intraocular pressure and corneal blood staining, and secondary to immune thrombocytopenia is presented. The literature is reviewed with particular reference to the aetiology and treatment of spontaneous hyphaema and the role of intravenous immunoglobulins in the preoperative management of patients with thrombocytopenia who present for routine or emergency ocular surgery.- - - - - - - - - - ranking = 0.2keywords = black (Clic here for more details about this article) |
3/8. Sickle cell hyphema with secondary glaucoma in a non-black patient.A 5-year-old Mexican-American boy developed marked elevation of intraocular pressure in association with a small traumatic hyphema. Laboratory studies prompted by this clinical presentation revealed that the child had sickle trait. Pressure returned to normal after surgical evacuation of blood from the anterior chamber. Sickle cell hemoglobinopathy should be considered in the differential diagnosis of secondary glaucoma following blunt ocular trauma even in non-black patients.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
4/8. Transient open-angle glaucoma associated with sickle cell trait: report of 4 cases.Four black patients, all with sickle trait (SA), developed transient open-angle glaucoma with blood in Schlemm's canal. In 3 patients the condition followed blunt trauma, while in the fourth no antecedent trauma was described. The intraocular pressure became normal in all 4 cases with the resolution of the haemorrhage from the trabecular meshwork and Schlemm's canal.- - - - - - - - - - ranking = 0.2keywords = black (Clic here for more details about this article) |
5/8. The histopathology of black ball hyphema: a report of two cases.Two black ball clots manually expressed through limbal incisions four and seven days after total traumatic hyphema were examined histologically. The surface of both clots consists of a fibrin "pseudocapsule" with no attachments to intraocular structures. There is a cohesive internal structure formed by concentric fibrin layers. No fibroblastic or neovascular activity was present. Intracameral clots evolve differently than intravascular clots. True organization of the black ball hyphema clot does not appear to take place within the first seven days after black ball hyphema secondary to contusion trauma.- - - - - - - - - - ranking = 1.4keywords = black (Clic here for more details about this article) |
6/8. Delayed hyphema after argon laser iridectomy.A 77-year-old black woman without neovascularization developed spontaneous hyphema two days after laser iridectomy. Bleeding originated at the site of iridectomy. This complication has not been previously reported.- - - - - - - - - - ranking = 0.2keywords = black (Clic here for more details about this article) |
7/8. Reversal of retinal and optic disc ischemia in a patient with sickle cell trait and glaucoma secondary to traumatic hyphema.A 14-year-old black boy with sickle cell trait, who sustained a traumatic hyphema, developed moderately elevated intraocular pressure that failed to respond to carbonic anhydrase inhibitors and osmotic agents. On the tenth postinjury day, a sudden increased cupping of the optic disc and partial central retinal artery obstruction caused painless loss of vision. Reversal of the cupping, the retinal ischemia, and the intraocular pressure was documented following anterior chamber paracentesis, and visual acuity returned to 6/6. Pathophysiology of the posterior ischemia is discussed. This case documents the potentially debilitating course of traumatic hyphema in "benign" sickle cell trait and its avoidance with proper management. The authors endorse recent suggestions for careful observation of any sickle cell patient with traumatic hyphema, and recommend anterior chamber paracentesis, supplemental oxygen, and avoidance of osmotic agents, if secondary glaucoma develops following the initial trauma.- - - - - - - - - - ranking = 0.2keywords = black (Clic here for more details about this article) |
8/8. Surgical management of black ball hyphema with sodium hyaluronate.A surgical technique for removing black ball hyphema in a pseudophakic patient is described. Three days after a total postoperative hyphema developed, a solution of sodium hyaluronate, Healon, was injected into the anterior chamber through a 160 degrees limbal cataract incision. Healon dissected the clotted blood off the underlying iris and intraocular lens, maintained the anterior chamber, and expressed the clot in toto out of the eye. Postoperatively the patient had no further bleeding, the intraocular pressure remained normal, the pseudophakos remained clear and well positioned, and the cornea remained clear.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
