We examined 61 affected members of eight families with an inherited corneal dystrophy. The corneal abnormalities varied greatly from one member of a family to another. Some patients had only a few isolated endothelial vesicles, while others in the same family had severe secondary stromal and epithelial edema. In some patients edema was present at birth or(More)
The pathogenesis of Best's macular dystrophy (BMD) is poorly understood. Previous histopathologic descriptions of BMD have been published in the literature; however, all were from elderly persons who clinically exhibited late manifestations of the disease. In this article, light and electron microscopic observations of an earlier stage of BMD are reported.(More)
Transient central retinal artery occlusion (CRAO) was produced in 63 eyes of rhesus monkeys by lateral orbitotomy and temporary clamping of the central retinal artery (CRA) for between 15 and 270 minutes. Thirty-three eyes were examined at regular intervals for 12 to 22 weeks. Color fundus photography, fluorescein fundus angiography, electroretinography(More)
Photoradiation therapy (PRT) is a new technique that is currently under investigation for the treatment of a variety of solid malignant tumors. The technique involves systemic administration of hematoporphyrin derivative (HpD), a photosensitizing compound that is preferentially retained by malignant cells and photoactivation of the neoplasm with red light(More)
BACKGROUND AND OBJECTIVE We identified a large family affected with a macular dystrophy whose main clinical features are similar to those of Stargardt's disease. Unlike true Stargardt's disease, the disorder in this family is inherited in an autosomal dominant fashion. We sought to identify the chromosomal location of the disease-causing gene and to(More)
Ophthalmoscopic, fluorescein angiographic, electrophysiological, and morphological studies on 63 eyes of rhesus monkeys with acute transient experimental occlusion of the central artery of the retina (OCAR) showed that the retina suffered irreparable damage after ischaemia of 105 minutes but recovered well after ischaemia of 97-98 minutes. The tolerance(More)
The presentation and long-term visual outcome in 30 eyes with Terson syndrome is evaluated. In 25 of 30 eyes (83%), visual acuity of 20/50 or better was attained. This occurred in 12 of 16 eyes (75%) managed by observation alone and 12 of 14 eyes (86%) treated by pars plana vitrectomy. The most common long-term sequelae in all eyes studied was the formation(More)
Combined hamartomas of the retina and retinal pigment epithelium are rare fundus lesions. By combining cases seen by members of The Macula Society, clinical data was collected on 60 patients with combined hamartomas. We reviewed the clinical presentations, ophthalmoscopic, and fluorescein angiographic features and differential diagnosis of this tumor. Of 41(More)
The chief aim of this study has been to develop a clearer understanding of the developing and adult ciliary complex in order to correlate its structure with the normal formation of aqueous humor. The eyes of prenatal, neonatal and adult albino and pigmented rabbits were studied by light and electron miscroscopy. Since studies by earlier investigators(More)
Visual outcome was analysed in 16 consecutive eyes with symptomatic retinal arteriolar macroaneurysms treated by direct laser photocoagulation and 26 consecutive symptomatic eyes followed with no treatment. No difference existed between groups in presenting visual acuity, macular involvement, presence of macular subretinal fluid, or presence or location of(More)
