Ophthalmomyiasis interna lentis.

An examination in 1981 of a 62-year-old white woman, who had had decreased vision in the right eye since she was 11 years old, revealed the typical retinal findings of ophthalmomyiasis. The larval exoskeleton was found imbedded temporally in the lens. On reexamination in 1989 no change was found.

Angioid streaks associated with hereditary spherocytosis.

We examined members of a family in whom hereditary spherocytosis had appeared in three generations. Angioid streaks were confirmed in the second generation and presumed to exist in the first generation. A woman in the third generation with hereditary spherocytosis did not have angioid streaks but these are age-related and may develop later. The one individual in the second generation without hereditary spherocytosis did not have angioid streaks. Angioid streaks associated with hereditary spherocytosis in this family did not appear to be coincidental. Patients with hereditary spherocytosis should be examined for angioid streaks because of the implications for their vision.

Diabetic vitrectomy.

Diabetic vitrectomy is usually performed to remove vitreous blood or to relieve traction of the macula. In addition to removing vitreous opacities and severing all anteroposterior connections of the posterior hyaloid face with a cutting and sucking probe, tangential traction in and around the macula is eliminated by sectioning preretinal membranes with intraocular scissors. Complications are significant in terms of both their incidence and their consequences. They include choroidal or subretinal infusion, peripheral and posterior retinal breaks, intraoperative bleeding, and neovascular glaucoma. Proper management can minimize the occurrence and adverse effects of these complications. If prognostic factors are favorable, visual improvement occurs in 78 to 59% of eyes postoperatively. Preoperative iris neovascularization, florid proliferative diabetic retinopathy, long-standing detachment of the macula, and iatrogenic retinal breaks are all correlated with significantly lower success rates. Three independent studies have shown that if visual improvement is present 6 months postoperatively, the results are usually long-standing [2, 8, 20].

Ocular manifestations of drug abuse.

Abuse of drugs, including some used clinically and others with no legal or clinical use, can cause ocular injury and disease. Ocular manifestations of drug abuse may be due to the substances themselves, to invasive methods of administration, or to injury suffered during states of altered consciousness. Grouping the drugs into five categories (opiates, marijuana, stimulants, depressants and hallucinogens), the authors describe the pharmacologic, congenital, toxic, infectious, embolic, and psychological ocular manifestations of their abuse.
