1/8. Neovascularization of the optic disc after highly active antiretroviral therapy in an AIDS patient with cytomegalovirus retinitis--A new immune recovery-related ocular disorder?A patient with AIDS and cytomegalovirus (CMV) retinitis developed a massive bilateral peripheral occlusive vasculopathy with a bilateral neovascularization of the optic disc five weeks after the introduction of highly active antiretroviral therapy (HAART). No associate cause of occlusive vasculopathy was found. Occlusive vasculopathy and optic disc neovascularization may be an immune recovery-related ocular disorder.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
2/8. optic disk neovascularization in a patient with cytomegalovirus retinitis associated with renal transplantation.PURPOSE: To report the development of optic nerve head neovascularization during the recovery phase of cytomegalovirus (CMV) retinitis in a renal allograft recipient. CASE REPORT: A 46-year-old male renal allograft recipient developed CMV retinitis seven months after transplantation. At the time of the diagnosis, the patient was being immunosuppressed with prednisone, cyclosporine, and azathioprine, and was treated with repeated intravitreal and intravenous ganciclovir. Six weeks after the initiation of therapy, optic disk neovascularization developed. This was confirmed by fluorescein angiography, which showed no areas of retinal capillary nonperfusion. At this stage, active retinal lesions were partially resolved. Apart from intraocular inflammation, no other cause of neovascularization was detected. Over the following six months, optic disk neovascularization regressed spontaneously without causing vitreous hemorrhage or visual loss. There was no recurrence of CMV retinitis during follow-up. CONCLUSION: optic disk neovascularization may develop in the healing phase of CMV retinitis in renal transplant recipients.- - - - - - - - - - ranking = 4.5keywords = neovascularization (Clic here for more details about this article) |
3/8. Photodynamic therapy with verteporfin for subfoveal choroidal neovascularization secondary to toxoplasmic chorioretinal scar.BACKGROUND: To assess the effect of photodynamic therapy in the treatment of subfoveal choroidal neovascularization consecutive to a toxoplasmic chorioretinal scar. history AND SIGNS: Three patients with a previous history of toxoplasmic chorioretinal scar noticed a decrease in visual acuity and metamorphopsia. Fundus examination and fluorescein angiography revealed the presence of subfoveal choroidal neovascularization at the edge of the toxoplasmic chorioretinal scar. THERAPY AND OUTCOME: The first patient, aged 78, was treated by photodynamic therapy followed by three subsequent treatments of feeder vessel by laser photocoagulation. visual acuity decreased during follow-up in the presence of recurrence of choroidal neovascularization and subretinal fibrosis. The second patient, a 20-year-old lady, was treated with three sessions of photodynamic therapy for a subfoveal choroidal neovascularization related to a toxoplasmic scar. visual acuity was stabilized on the last follow-up visit at 0.3. The third patient, aged 53, received four treatments with photodynamic therapy at an interval of 3 - 4 months. choroidal neovascularization was stabilized and the last visual acuity was 0.2. CONCLUSIONS: This preliminary report suggests that photodynamic therapy with verteporfine may be an effective therapeutic modality for subfoveal choroidal neovascularization related to a toxoplasmic chorioretinal scar. Further assessment is needed in order to confirm this preliminary findings.- - - - - - - - - - ranking = 5keywords = neovascularization (Clic here for more details about this article) |
4/8. Disc neovascularization in patients with AIDS and cytomegalovirus retinitis.The authors report two patients with AIDS and cytomegalovirus retinitis who developed disc neovascularization. The disc neovascularization regressed spontaneously over several months and did not cause vitreous hemorrhage or visual loss.- - - - - - - - - - ranking = 3keywords = neovascularization (Clic here for more details about this article) |
5/8. Regression of disc neovascularization by photocoagulation in the acute retinal necrosis syndrome.Disc neovascularization developed in one eye of a 40-year-old white woman with the acute retinal necrosis syndrome. krypton laser scatter photocoagulation was placed in areas of nonnecrotic and segmentally nonperfused retina that were demonstrated by fluorescein angiography. Marked reduction in disc neovascularization was noted clinically 16 days after laser treatment and was confirmed angiographically 4 weeks after treatment. Neovascularization was completely regressed at 9 weeks after treatment. The authors postulate that the retinal vasculitis and nonperfusion produced retinal ischemia which stimulated neovascular proliferation, and that photocoagulation caused regression of the neovascularization.- - - - - - - - - - ranking = 3.5keywords = neovascularization (Clic here for more details about this article) |
6/8. Pseudoinflammatory macular dystrophy.A family with pseudoinflammatory macular dystrophy (PMD) is presented. This dominantly inherited macular dystrophy has its onset in the 3rd to 5th decades with the earliest manifestation being a macular subretinal neovascular network. Visual function tests (ERG, EOG, visual fields, retinal sensitivity) in the early and late stages indicates this is local or geographic disease. This dystrophy should be differentiated from other hereditary causes for subretinal neovascularization (angioid streaks, vitelliform dystrophy, dominant drusen of Bruch's membrane, optic nerve drusen and myopia). It is suggested that treatment be directed at early obliteration of the subretinal neovascularization with intense photocoagulation since the outcome in virtually all cases of untreated PMD is legal blindness.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
7/8. 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 = 0.5keywords = neovascularization (Clic here for more details about this article) |
8/8. retinal neovascularization associated with acute retinal necrosis.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 ischemia, was the cause of new vessel formation. Analysis of vitreous mononuclear cells with monoclonal antibodies and the fluorescence-activated cell sorter (FACS) revealed mostly T cells; a pattern consistent with intraocular infection as the cause of ARN. The pathogenesis of intraocular infection is complex and some patients with ARN may be helped by systemic immunosuppression (ie, corticosteroids).- - - - - - - - - - ranking = 2.5keywords = neovascularization (Clic here for more details about this article) |
