1/101. Histopathological findings in proliferative membrane from a patient with sarcoid uveitis.BACKGROUND: Sarcoid uveitis is occasionally accompanied by proliferative changes, such as retinal neovascularization and vitreous hemorrhage. Steroid administration, retinal photocoagulation, and vitrectomy may be indicated in such proliferative cases. CASE: A 19-year-old woman presented with proliferative sarcoid uveitis accompanied by recurrent vitreous hemorrhage. OBSERVATIONS: At the initial examination, bilateral vitreous opacity, retinal exudates, mild vitreous hemorrhage, retinal vasculitis, and neovascularization of the retina and optic disc were observed. Although prednisolone was administered and panretinal photocoagulation was performed several times, recurrent vitreous hemorrhage continued. Since the vitreous hemorrhage was not absorbed, pars plana vitrectomy and lensectomy were performed. After surgery, neovascularization and intraocular inflammation decreased, and the corrected visual acuity in the right eye improved to 20/50. Histopathologic analysis of the proliferative membrane removed during surgery revealed substantial neovascularization and numerous neutrophils in the vessels. CONCLUSIONS: Based on these findings, an inflammatory reaction as well as retinal ischemia were thought to be involved in the proliferative changes in this patient.- - - - - - - - - - ranking = 1keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
2/101. Focal retinal pigment epithelial dysplasia associated with fundus flavimaculatus.BACKGROUND: One or more focal dysplastic lesions of the retinal pigment epithelium (RPE) occurred in 15 eyes of 10 patients with fundus flavimaculatus. methods: review of patient records including an attempt to obtain follow-up information concerning a history of previous ocular trauma. RESULTS: Mild antecedent ocular trauma occurred to the eye with a dysplastic lesion in two patients. Dysplastic lesions were most frequently solitary and located temporal to the macula. Subretinal neovascularization accompanied two of the dysplastic lesions. The lesions were multifocal and present bilaterally in two patients. CONCLUSIONS: In fundus flavimaculatus, progressive lipofuscin storage is responsible for engorgement and hypertrophy of the RPE. Dysplastic lesions of the RPE probably result from reactive hyperplasia and fibrous metaplasia of RPE cells in response to acute disruption of fragile, hypertrophied RPE cells that may be enormously enlarged in the area of yellow flecks. This disruption may occur in response to trauma, focal inflammation, or other localized stimuli. patients with fundus flavimaculatus should be cautioned concerning the possible role of trauma in causing dysplastic changes in the RPE and visual loss.- - - - - - - - - - ranking = 0.55461484643837keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
3/101. Histopathologic study of presumed parafoveal telangiectasis.PURPOSE: To report the postmortem histopathologic features that closely resemble the clinical features of parafoveal telangiectasis. methods: light and electron microscopy. RESULTS: Histopathologic features included macular edema; telangiectatic vessels; retinal, subretinal, and superficial retinal neovascularization; retinal pigment epithelial hyperplasia around neovascular aggregates; retinal-choroidal vascular anastomosis; and superficial pigmented cells with lipofuscin. CONCLUSION: The postmortem histopathologic findings in a 36-year-old woman with down syndrome and other systemic conditions correlate with features noted in previous reports of presumed parafoveal telangiectasis.- - - - - - - - - - ranking = 0.55461484643837keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
4/101. radiation-associated choroidal neovasculopathy, exudative detachment and neovascular glaucoma. A case report.radiotherapy remains a controversial type of therapy for subfoveal neovascularization. Recently a peculiar pattern of neovascular growth of the irradiated choroidal neovascular membrane has been described. This evolution may be associated with extensive exudative reaction. In one of our patients with this complication, the disease progressed to a total exudative retinal detachment and neovascular glaucoma.- - - - - - - - - - ranking = 0.14846171785388keywords = neovascularization (Clic here for more details about this article) |
5/101. retinal vasculitis occurring with common variable immunodeficiency syndrome.PURPOSE: To report severe retinal vasculitis causing decreased vision in three patients with the common variable immunodeficiency syndrome. METHOD: Case report. Three patients with common variable immunodeficiency syndrome developed decreased vision secondary to retinal vasculitis. fluorescein angiography was performed in all three patients. Peribulbar injections were given in one patient, and two patients were treated with oral steroids and cyclosporin. RESULTS: All three patients were young and had classic common variable immunodeficiency syndrome. Bilateral retinal vasculitis and diffuse retinal edema were present in all three patients, and two patients had retinal neovascularization in the absence of ischemia. No evidence of intraocular infection was present, and none was detected systematically. visual acuity decreased in five of the six eyes and was responsive to treatment in only one patient (both eyes). CONCLUSION: retinal vasculitis may be another autoimmune manifestation of common variable immunodeficiency syndrome.- - - - - - - - - - ranking = 0.55461484643837keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
6/101. Idiopathic polypoidal choroidal vasculopathy and sickle cell retinopathy.PURPOSE: To report a patient who had concomitant idiopathic polypoidal choroidal vasculopathy and sickle cell retinopathy. METHOD: Case report. A 46-year-old black woman presented with sudden onset of "blurring" in the left eye. Her ocular history was unremarkable, and her medical history was relevant for sickle cell disease with yearly episodes of sickle cell crises. RESULTS: Both eyes had evidence of idiopathic polypoidal choroidal vasculopathy and peripheral retinal neovascularization secondary to sickle cell disease. The left eye had hemorrhagic retinal pigment epithelial detachments secondary to idiopathic polypoidal choroidal vasculopathy. CONCLUSION: We present this case as an example of concomitant sickle cell retinopathy and idiopathic polypoidal choroidal vasculopathy. We are unaware of previous reports with these findings.- - - - - - - - - - ranking = 0.55461484643837keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
7/101. Familial spastic paraplegia and maculopathy with juxtafoveolar retinal telangiectasis and subretinal neovascularization.PURPOSE: To describe a previously unreported condition involving familial spastic paraplegia and a peculiar type of maculopathy. methods: Two pairs of siblings were studied. All four cases underwent serial clinical examinations, fundus photography, and fluorescein angiography. Two siblings had extensive investigations. RESULTS: Characteristics of the four cases include spastic paraplegia diagnosed in the first decade of life and visual loss at about age 9 due to a maculopathy with an abnormal vascular complex. In the early stages, parafoveal dilatation of the capillary network was noted. The later stages were characterized by cystic macular degeneration, and seven of eight eyes developed fibrovascular scars with retinochoroidal anastomoses, pigment migration, and atrophic changes. In two siblings, electro-oculographic findings were subnormal, whereas results of electroretinography, magnetic resonance imaging of the brain and spinal cord, and metabolic and karyotype studies were normal. These siblings were an Indonesian girl and boy; the other siblings were white males. There was no consanguinity of the parents and family history was unremarkable. CONCLUSIONS: This study suggests that the two pairs of siblings have an identical familial and probably recessive disorder with neurodegenerative changes that have caused paraplegia and a peculiar maculopathy associated with anomalous retinal vascular complexes, retinochoroidal anastomoses, and subretinal neovascularization.- - - - - - - - - - ranking = 2.7730742321918keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
8/101. Posterior segment neovascularization associated with acute ophthalmic artery obstruction.PURPOSE: To report previously unrecorded ocular neovascularization associated with acute ophthalmic artery obstruction (AOAO) that presents clinical manifestations of acute concomitant obstruction of the retinal and posterior ciliary circulations. methods: This report documents the clinical, fluorescein angiographic, and histopathologic findings in two patients with AOAO followed by posterior segment neovascularization. RESULTS: Ophthalmoscopic findings showed whitening of the posterior pole, arterial attenuation, and a pale optic disk. Serial fluorescein angiograms showed a nearly total shutdown of choroidal and retinal perfusion, degeneration of the retinal pigment epithelium and choriocapillaris, and eventual development of a huge neovascular frond at the posterior pole. Histopathologic examination of the enucleated eyeball showed inner retinal necrosis caused by central retinal artery obstruction, degeneration of the outer retina with choriocapillaris obstruction caused by impairment of choroidal circulation, and a thick preretinal neovascular frond at the posterior pole. CONCLUSIONS: These results suggest that AOAO can induce ocular neovascularization, which to the authors' knowledge has not yet been reported.- - - - - - - - - - ranking = 1.0392320249771keywords = neovascularization (Clic here for more details about this article) |
9/101. retinitis pigmentosa associated with peripheral sea fan neovascularization.PURPOSE: To describe a case with retinitis pigmentosa associated with sea fan type retinal neovascularization. methods: Complete ocular examination including fluorescein angiography was performed in a 9-year-old girl. RESULTS: Ophthalmoscopically, in addition to arteriolar narrowing and bone corpuscular pigmentation of both retinae, a vascular lesion with surrounding intraretinal exudation was noted in the upper equatorial region of the right eye. On fluorescein angiography, the lesion stained in the form of a sea fan neovascularization. CONCLUSION: Sea fan type of neovascularization can be seen in association with retinitis pigmentosa. fluorescein angiography is important in identifying the exact nature of such a lesion.- - - - - - - - - - ranking = 1.4453851535616keywords = retinal neovascularization, neovascularization (Clic here for more details about this article) |
10/101. Central retinal vein occlusion due to herpes zoster as the initial presenting sign in a patient with acquired immunodeficiency syndrome (AIDS).Central retinal vein occlusion (CRVO) due to herpes zoster has rarely been reported. Varicella zoster virus is a common opportunistic infection in patients with AIDS. This case report is about a 40-year-old man with herpes zoster ophthalmicus and central retinal vein occlusion of the right eye who is hiv-positive. Although the lesion resolved following treatment with intravenous acyclovir and oral steroid, the patient subsequently developed florid disc neovascularization and vitreous hemorrhage. The paper highlights CRVO as the initial presentation in an AIDS patient with herpes zoster ophthalmicus.- - - - - - - - - - ranking = 0.14846171785388keywords = neovascularization (Clic here for more details about this article) |
