11/15. Two sisters with telangiectases [corrected], spondyloepiphyseal dysplasia, hypothyroidism, neovascularization and tractional retinal detachments: a new entity?Two sisters had an unusual constellation of findings, including telangiectases [corrected] involving the face and limbs, unclassifiable spondyloepiphyseal dysplasia, hypothyroidism, and tractional retinal detachment preceded by retinal and iris neovascularization. To our knowledge, this combination of defects has not been previously documented in the literature.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
12/15. 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 = 0.2keywords = neovascularization (Clic here for more details about this article) |
13/15. Familial exudative vitreoretinopathy.Two sisters and a brother with the syndrome of familial exudative vitreoretinopathy are described (FEV). Findings associated with this condition include temporal neovascularization, vitreous hemorrhage, and retinal detachment. Familial exudative vitreoretinopathy is a genetic syndrome with nearly complete penetrance but widely variable expressivity. The differential diagnosis is fairly extensive. This condition is sometimes confused with retrolental fibroplasia, and FEV is probably a more frequently occurring disease than previously thought, because of confusion with RLF. The pathophysiologic mechanism, natural history, and optimal treatment of this disease are matters of debate. With active surgical management, three of the four eyes which presented to us for treatment have visual acuity of 20/30 or better.- - - - - - - - - - ranking = 0.2keywords = neovascularization (Clic here for more details about this article) |
14/15. Myelinated nerve fibers and retinal vascular abnormalities.BACKGROUND/PURPOSE. Abnormal retinal vessels may develop in a region of myelinated nerve fibers, and these vessels may cause vitreous hemorrhages. methods. The clinical histories of seven patients with retinovascular abnormalities in a patch of myelinated nerve fibers are presented. None of the reported patients had other evidence of systemic disease. The cases were traced by a multicentric retrospective study. RESULTS. Retinal vascular abnormalities ranged from mild telangiectasis to frank neovascularization, with or without obstruction of the capillary network and signs of branch artery and vein occlusion. Age at diagnosis ranged from 15 to 68 years. Vitreous hemorrhages occurred in the four youngest patients and occurred at 15, 27, 27, and 43 years of age. Laser photocoagulation was applied in three patients and vitrectomy was performed in one. CONCLUSION. The authors' findings suggest that the abnormal structure of the myelinated nerve fibers and the thickened nerve fiber layer of the affected portions of retina may play a role in the onset of retinal vascular abnormalities and eventually cause telangiectasis, branch artery and vein occlusion, neovascularization, and vitreous hemorrhages. This suggestion is based on the absence of other causes of neovascularization or vitreous hemorrhage in all seven patients, and on the relatively young age of four of the patients with this association.- - - - - - - - - - ranking = 0.6keywords = neovascularization (Clic here for more details about this article) |
15/15. Surgical removal of subfoveal neovascularization in idiopathic juxtafoveolar retinal telangiectasis.PURPOSE: To investigate the efficacy of the surgical removal of subfoveal choroidal neovascularization in patients with type 2A idiopathic juxtafoveolar retinal telangiectasis. methods: Two patients with bilateral acquired idiopathic juxtafoveolar retinal telangiectasis and a subfoveal choroidal neovascular membrane underwent surgical excision of the membrane using standard subretinal surgical techniques. RESULTS: In both cases, surgical removal of the neovascular membrane was complicated by an intimate adherence of the membrane with the overlying neurosensory retina in an area of retinochoroidal anastomosis. A retinal dehiscence occurred in both instances at the time of surgery. Postoperative visual outcome was poor. CONCLUSION: The retinochoroidal anastomoses often visualized in cases of subretinal neovascularization complicating bilateral acquired IJFRT could indicate that there is a fairly marked adherence of the neovascular membrane to the neurosensory retina. Attempts at surgical removal of subretinal membranes in this disease entity with current techniques may be contraindicated.- - - - - - - - - - ranking = 1.2keywords = neovascularization (Clic here for more details about this article) |
