Disk and peripheral retinal neovascularization secondary to talc and cornstarch emboli.

A 30-year-old man was examined because of blurred vision. The symptoms had occurred immediately after the patient had injected himself intravenously with crushed, unfiltered, methylphenidate HCl (Ritalin) tablets. Fine yellow-white crystals were scattered throughout the retin of both eyes. The crystals were presumed to be talc emboli. Disk and peripheral retinal neovascularization were present. Fluorescein angiography revealed widespread retinal capillary nonperfusion. This is the first reported case, to the best of my knowledge, of disk neovascularization occurring after intravenously injected, crushed, unfiltered, methylphenidate HCl tablets.

Pars plana vitrectomy in the management of blood-induced glaucoma with vitreous hemorrhage.

Four consecutive cases are reported in which pars plana vitrectomy was used to treat eyes with blood-induced glaucoma complicating vitreous hemorrhage after cataract surgery. Vitrectomy resulted in removal of the posterior reservior of cells and cellular debris and cured the elevated intraocular pressure in 3 eyes. One eye required a second glaucoma procedure and long-term acetazolamide therapy. The excised vitreous was examined microscopically with several techniques, including use of a millipore filter to concentrate the cellular elements combined with a modified Papanicolaou staining technique, routine staining of sections of millipore filters, and routine staining of vitreous processed in a celloidin bag. These techniques showed variable proportions of erythrocytes, erythrocytic debris, free hemoglobin, ghost erythrocytes and macrophages containing erythrocytic debris and hemosiderin.

Congenital retinal arterial loops and vitreous hemorrhage.

In two adolescents, mild vitreous hemorrhage occurred from the area of retinal arterial loops near the optic nerve. In both cases the hemorrhage cleared without further complications. This vascular malformation may be associated with secondary complications more frequently than has previously been reported.

The unexpected guest: problem of iris reposition.

A 31-year-old male presented with a corneal laceration and iris prolapse in the left eye. The surgical repair was complicated by epithelial ingrowth on the lens capsule. The appropriate management of both the initial trauma and subsequent complication is discussed.

Vitreous hemorrhage secondary to juxtapapillary vascular hamartoma of the retina.

The authors report an unusual case with vitreous hemorrhage due to a vascular hamartoma of the optic nerve-head and treated by pars plana vitrectomy. Systemic abnormalities included a seizure disorder, periungual fibroma, and intracranial calcifications suggesting systemic tuberous sclerosis. However, the ocular lesion resembled a juxtapapillary pigment epithelial and retinal hamartoma or a capillary hemangioma rather than an astrocytic hamartoma. Vitreous hemorrhage has been reported previously in eyes with capillary hemangiomas and astrocytic hamartomas, but not in eyes with juxtapapillary pigment epithelial and retinal hamartomas. In young patients with vitreous hemorrhage of unknown cause, juxtapapillary hamartomas should be considered in the differential diagnosis.
