11/39. Late development of chorioretinal lesions in birdshot retinochoroidopathy.The clinical manifestations of diffuse retinochoroidopathy after recurrent episodes of vitriitis led to the diagnosis of birdshot retinochoroidopathy in two patients in whom the initial lesions were cystoid macular edema and papillophlebitis. Although the onset and clinical characteristics of the early lesions varied, both patients had manifestations of chronic retinal vasculitis. We observed the late appearance and evolution of the characteristic cream-colored depigmented spots which were not present in the early stages of the disease. In addition the second case also developed choroidal neovascularization. Serial electroretinographic examinations showed that this disorder has a progressive course from focal lesions to widespread diffuse changes.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
12/39. vitrectomy when asteroid hyalosis prevents laser photocoagulation.Asteroid hyalosis is a relatively common disorder of the vitreous that rarely causes visual impairment. However, funduscopic examination and laser photocoagulation can be difficult because of reflections off the asteroid bodies. Although vitrectomy is rarely indicated for impaired visual acuity, we report three cases in which pars plana vitrectomy was necessary to permit required retinal laser photocoagulation. In two patients with proliferative diabetic retinopathy and a third patient with subretinal neovascularization marked asteroid hyalosis precluded photocoagulation by standard techniques.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
13/39. Ocular rosacea in blacks.In three black men (57, 64, and 61 years old) with the ocular manifestations of rosacea, the diagnosis was not initially suspected because the pathognomonic skin changes of rosacea were obscured by the skin hyperpigmentation. Ocular involvement ranged from blepharitis and conjunctival hyperemia to sight-threatening problems such as corneal neovascularization, thinning, ulceration, and perforation. Treatment with oral tetracycline and topical corticosteroids appeared to be as effective in these patients as in previously described white patients.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
14/39. Presumed chronic ocular histoplasmosis syndrome: a clinical-pathologic case report.An eye of a patient with clinically typical presumed ocular histoplasmosis was studied by light microscopy, electron microscopy and immuno-fluorescence techniques. There was clinical and pathological evidence of anterior segment involvement. The posterior segment showed granulomatous and nongranulomatous chorioretinal lesions with and without subretinal neovascularization. Immunohistopathological staining for histoplasma antigens revealed positive staining at sites of lymphoid inflammation. Organisms were not identified.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
15/39. Photocoagulation treatment of radiation retinopathy.We studied the visual and anatomic effects of focal photocoagulation for clinically significant radiation macular edema in five eyes of four patients and panretinal photocoagulation for proliferative radiation retinopathy in six eyes of three patients. Focal and limited scatter photocoagulation was successful in preventing further vision loss in all five eyes treated for macular edema. Three eyes treated with panretinal photocoagulation had regression of neovascularization. The other three eyes treated for proliferative retinopathy subsequently had dense vitreous hemorrhages that required vitrectomy for restoration of useful vision.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
16/39. Atypical retinitis proliferans, retinal telangiectasis, and vitreous hemorrhage in a patient with tuberous sclerosis.This report describes an unusual case of recurrent vitreous hemorrhage and atypical retinal neovascularization in a patient with tuberous sclerosis. During three years of observation, the patient also developed retinal telangiectasis with macular edema and lipid exudation. Although the patient did not have an obvious astrocytic hamartoma, a diffuse, flat retinal hamartoma within the nerve fiber layer was suspected.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
17/39. Congenital pupillary-iris-lens membrane with goniodysgenesis (a new entity).We encountered two clinically similar but genetically unrelated cases of a disorder characterized by an unusual white pupillary-iris-lens membrane with extension to a prominent Schwalbe's line, the membranes were vascularized and their appearance changed over time. In both cases the abnormality was unilateral. Anomalous chamber angles were seen on gonioscopy. The clinical appearance is similar to a combination of iridogoniodysgenesis and pupillary membrane. However, our two cases are unique and fit into neither category. We postulate that this is a new entity consisting of an anomalous chamber angle and iris-lens membrane resulting from a localized iris (pupillary membrane), infarct with secondary neovascularization, during formation of the chamber angle.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
18/39. Regression of iris neovascularization following panretinal photocoagulation.A 57-year-old woman with proliferative diabetic retinopathy in both eyes also had iris surface neovascularization with early angle neovascularization in her right eye, which regressed completely following treatment with panretinal photocoagulation. Histopathologic examination confirmed the complete absence of abnormal vessels on the iris surface or in the iridocorneal angle of the right eye; an avascular fibrous membrane persisted on a segment of the posterior iris pigment epithelium near the pupil. There was advanced rubeosis in the untreated left eye.- - - - - - - - - - ranking = 6keywords = neovascularization (Clic here for more details about this article) |
19/39. argon laser treatment of retinal neovascularization associated with sarcoidosis.A 22-year-old Japanese woman with systemic sarcoidosis had retinal neovascularizations at seven loci with repeated vitreous hemorrhage in her right eye. Oral administration of prednisone was not effective. However, argon laser photocoagulation to the neovascularizations obliterated the neovascular fronds except at the optic nerve head; three months from the treatment, the neovascularization at the optic nerve head regressed spontaneously. No serious complications have occurred, and the vitreous hemorrhage has not recurred for the past two years. From these results, argon laser photocoagulation was thought to be effective for the treatment of retinal neovascularization in sarcoidosis.- - - - - - - - - - ranking = 8keywords = neovascularization (Clic here for more details about this article) |
20/39. Macular lesions in blacks with the presumed ocular histoplasmosis syndrome.Six black patients had fundus lesions diagnostic of the presumed ocular histoplasmosis syndrome. All patients had peripapillary changes or peripheral punched-out chorioretinal lesions, or both. Five of the six had macular subretinal neovascularization, disciform scarring, or an atrophic macular lesion, and one patient had a macular hole; four of five patients tested had a positive histoplasmin skin test. The macular involvement was bilateral in three of the six cases. HLA B-7 was present in one of four patients who had HLA typing. Macular involvement can occur in blacks with the presumed ocular histoplasmosis syndrome.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
