Retinitis Pigmentosa and Retinal Neovascularization

Ophthalmology, 1986
Four patients with retinitis pigmentosa and either disc or peripheral retinal neovascularization with recurrent vitreous hemorrhage are described. One patient with peripheral retinal neovascularization also had rubeosis and neovascular glaucoma. The effects of relative hyperoxia on the retinal microcirculation in retinitis pigmentosa as well as ...

Peripheral Retinal Neovascularization in Sarcoidosis

Archives of Ophthalmology, 1975
Three black patients with peripheral retinal sea fan neovascularization were found to have sarcoidosis. The periphlebitic process may be the cause of stasis, hypoxia, and a secondary vasoproliferative stimulus. We noted the peculiar finding of a vessel passing through the neovascular tissue into the peripheral retina.

Retinal and choroidal neovascularization

Journal of Cellular Physiology, 2000
The unique vascular supply of the retina, the ability to visualize the vasculature in vivo, and the ability to selectively express genes in the retina make the retina an ideal model system to study molecular mechanisms of angiogenesis. In addition, this area of investigation has great clinical significance, because retinal and choroidal ...

Occlusive Retinal Arteriolitis with Neovascularization

American Journal of Ophthalmology, 1976
A 34-year-old white woman who had used oral contraceptives for six years showed an occlusive bilateral retinal arteriolitis that resulted in a branch arteriolar occlusion in the right eye and retinal neovascularization. Three years later, we observed active arteriolitis in the left eye with successive occlusion of several branch arterioles. The disease

Retinal Neovascularization and Ocular Toxoplasmosis

American Journal of Ophthalmology, 1984
Retinal neovascularization, a rare complication of ocular toxoplasmosis, is a source of vitreous hemorrhage. We examined three patients (all women, 70, 36, and 19 years old) with inactive toxoplasmosis scars associated with occlusion of a retinal arteriole or venule passing through the scar, capillary nonperfusion, and adjacent retinal ...

RETINAL NEOVASCULARIZATION ASSOCIATED WITH ACUTE RETINAL NECROSIS

Retina, 1983
Unilateral acute retinal necrosis (ARN), developed in a previously healthy 17-year-old boy. Neovascularization of the retina and optic disc was observed when the opaque vitreous was removed by pars plana vitrectomy. Following surgery there was a rapid resolution of neovascularization suggesting that intraocular inflammation, rather than retinal ...

Retinal Ischemia With Neovascularization in Cisplatin Related Retinal Toxicity

American Journal of Ophthalmology, 2006
To report a case of macular ischemia and retinal neovascularization in a patient who received cisplatin related chemotherapy.Interventional case report.A patient with germ cell testicular tumor received polychemotherapy (bleomycin, etoposide, and cisplatin or BEP) for a recurrence of his tumor. Ten weeks after completion of treatment, he presented with

Neovascularization Detection on Retinal Images

2017
Proliferative Diabetic Retinopathy (PDR) is characterized by the growth of new abnormal, thin blood vessels called neovascularzation that spread along the retinal surface. An automated computer aided diagnosis system needs to identify neovasculars for PDR screening. Retinal images are often noisy and poorly illuminated.
