1/536. Pars plana vitrectomy and subretinal surgery for ocular toxocariasis.The clinical course of ocular toxocariasis and the chronological development of peripheral retinal and macular granulomas are reported. Removing the epiretinal as well as subretinal component of the granuloma via pars plana vitrectomy and retinotomy techniques yielded an excellent clinical result. Clinicopathologic correlation of the specimen confirmed the diagnosis with histological evidence of degenerated larval structures in granulomatous inflammation.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/536. Retinal findings in Takayasu's arteritis.PURPOSE: To describe unusual as well as typical ocular findings in eight patients with Takayasu's disease. methods: The ophthalmic manifestations and clinical courses of eight patients with Takayasu's disease were evaluated. RESULTS: All patients had clinical and angiographic evidence of pulseless disease. Typical findings included retinal venous congestion, fluorescein staining, capillary drop-out, microaneurysms and arteriovenous shunting. Unusual findings included cotton wool spots, anterior ischemic neuropathy and retinal emboli. In one case microaneurysms disappeared after carotid bypass surgery. Several patients had profound, transient, visual loss with changes in head posture. CONCLUSION: Takayasu's disease can cause a variety of retinal manifestations. Less common findings include cotton wool spots, anterior ischemic optic neuropathy and retinal emboli.- - - - - - - - - - ranking = 0.2keywords = ocular (Clic here for more details about this article) |
3/536. argon laser photocoagulation in ocular histoplasmosis syndrome.argon laser photocoagulation was performed on 30 patients with ocular histoplasmosis syndrome involving the macula. Selection of patients for photocoagulation was dependent upon locating the sub-retinal neovascularization (SRNV) at least one vein-width removed from the capillary-free zone of the fovea on fluorescein angiography. Of the 30 treated patients, 27 maintained or improved visual acuity an average of 1 1/2 years following photocoagulation.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
4/536. Dark spots in late-phase indocyanine green angiographic studies in a patient with presumed ocular histoplasmosis syndrome.PURPOSE: We analyzed indocyanine green (ICG) angiograms in a patient with presumed ocular histoplasmosis syndrome (POHS) complaining about "seeing spots" and decreased visual acuity in order to identify the pathologic process. patients AND methods: A 30-year-old caucasian man with clinical signs of POHS who had previously undergone laser photocoagulation for secondary choroidal neovascularization developed visual disturbances primarily in his temporal visual field. We performed fundus photography, fluorescein angiography and ICG angiography before, during and after the episode of visual disturbance. ICG angiographic findings were correlated to fundus photographs and fluorescein angiograms. RESULTS: Fundus examination, fluorescein angiograms and early-phase ICG angiograms were unremarkable at all time points. However, during the phase of visual disturbance, late-phase ICG angiographic study revealed hypofluorescent lesions in the area representing the visual disturbances. At 1 week follow-up, these hypofluorescent lesions were reduced in size and number; at 6 months follow-up they had completely resolved. CONCLUSIONS: Late-phase ICG angiographic study can provide additional information in inflammatory retinal disease by virtue of identifying areas of choroidal alterations while standard diagnostic examination remain unremarkable.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
5/536. diplopia secondary to aniseikonia associated with macular disease.OBJECTIVE: To provide an explanation for diplopia and the inability to fuse in some patients with macular disease. methods: We identified 7 patients from our practices who had binocular diplopia concurrent with epiretinal membranes or vitreomacular traction. A review of the medical records of all patients was performed. In addition to complete ophthalmologic and orthoptic examinations, evaluation of aniseikonia using the Awaya New aniseikonia Tests (Handaya Co Ltd, tokyo, japan) was performed on all patients. RESULTS: All patients were referred for troublesome diplopia. Six of the patients had epiretinal membranes and 1 had vitreomacular traction. All 7 patients had aniseikonia, ranging from 5% to 18%. In 5 of the patients the image in the involved eye was larger, and in the other 2 patients it was smaller than in the fellow eye. All patients had concomitant small-angle strabismus and at least initially did not fuse when the deviation was offset with a prism. Response to optical management and retinal surgery was variable. CONCLUSIONS: aniseikonia caused by separation or compression of photoreceptors can be a contributing factor to the existence of diplopia and the inability to fuse in patients with macular disease. Concomitant small-angle strabismus and the inability to fuse with prisms may lead the clinician to the incorrect diagnosis of central disruption of fusion. Surgical intervention does not necessarily improve the aniseikonia.- - - - - - - - - - ranking = 0.2keywords = ocular (Clic here for more details about this article) |
6/536. Nonsurgical management of binocular diplopia induced by macular pathology.OBJECTIVE: To treat binocular diplopia secondary to macular pathology. methods: Seven patients underwent evaluation and treatment. All had constant vertical diplopia caused by various maculopathies, including subretinal neovascularization, epiretinal membrane, and central serous retinopathy. visual acuity ranged from 20/20 to 20/30 in the affected eye. All except 1 patient had a small-angle, comitant hyperdeviation with no muscle paresis. Sensory evaluation demonstrated peripheral fusion and reduced stereoacuity. Neither prism correction nor manipulation of the refractive errors corrected the diplopia. A partially occlusive foil (Bangerter) of density ranging from 0.4 to 1.0 was placed in front of the affected eye to restore stable, single vision. RESULTS: The Bangerter foil eliminated the diplopia in all patients. Two patients elected not to wear the foil; 1 patient was afraid of becoming dependent, and the other was bothered by the visual blur. visual acuity in the affected eye was reduced on average by 3 lines. All patients maintained the same level of sensory fusion, with only 2 having reduced stereoacuity. Symptoms returned when the foil was removed or its density was reduced. CONCLUSION: Low-density Bangerter foils provide an effective, inexpensive, and aesthetically acceptable management for refractory binocular diplopia induced by macular pathology, allowing peripheral fusion to be maintained.- - - - - - - - - - ranking = 1.2keywords = ocular (Clic here for more details about this article) |
7/536. Retinal hamartoma in oral-facial-digital syndrome.Only recently have intraocular findings been described in oral-facial-digital syndrome (OFDS), including 5 cases of chorioretinal colobomas and 1 case of optic nerve coloboma. We report a case of a new ocular anomaly associated with this syndrome: a retinal hamartoma in a male infant with OFDS. The patient had bilateral retinal masses that were suspicious for retinoblastoma because of a family history of retinoblastoma. physical examination and imaging studies of the retinal masses could not differentiate between retinoblastoma, hamartoma, or persistent hyperplastic primary vitreous. Subsequent pathologic study of an enucleated globe was diagnostic of a retinal hamartoma. This case further illustrates the heterogeneity of ocular anomalies in OFDS and underscores the importance of a complete ophthalmologic evaluation in patients with this syndrome.- - - - - - - - - - ranking = 0.6keywords = ocular (Clic here for more details about this article) |
8/536. Punctate outer retinal toxoplasmosis in an hiv-positive child.PURPOSE: To discover whether the outer layer of the retina can be the site for toxoplasmosis in AIDS patients. methods: An hiv-positive child, who previously had a normal ocular examination, was reexamined three months later. This examination showed outer retinal lesions compatible with toxoplasmosis and positive IgM and IgG titers specific for that organism, despite the small drop in the CD4 count. RESULTS: During the first examination, the antibodies for toxoplasmosis were negative. At the three-months follow-up, the anti-toxoplasmosis antibodies were positive and the rest of the workup was negative, suggesting a strong correlation with the patient's fundus pattern. CONCLUSION: We describe a case of punctate outer retinal toxoplasmosis uveitis, which has been previously associated with immunocompetent hosts. We, however, believe that it can be seen in immunocompromised patients as well.- - - - - - - - - - ranking = 0.2keywords = ocular (Clic here for more details about this article) |
9/536. Demyelination of retinal myelinated nerve fibers in Behcet's disease.A 39 year-old Behcet's patient had demyelination of retinal myelinated nerve fibers after recurrent papillitis and vitritis. Oral prednisolone, cyclosporine, and later periocular corticosteroids and oral colchicine were used but demyelination continued over a 5 year-period. A pseudobulbar palsy with urinary incontinence and pyramidal tract signs developed and azathioprine and corticosteroids were used. Demyelination of retinal nerve fibers stopped and while treatment was underway, the central nervous system (CNS) signs were stable. While the ocular pathology of Behcet's can mirror the CNS signs, indeed optic nerve ischemic demyelination may signal the potential for CNS involvement; azathioprine with prednisone may be more effective in the long-term for optic nerve and CNS involvement than cyclosporine with prednisone.- - - - - - - - - - ranking = 0.4keywords = ocular (Clic here for more details about this article) |
10/536. central serous chorioretinopathy and hiv.BACKGROUND: patients with central serous chorioretinopathy (CSC) have sudden-onset, painless, uniocular blur that is typically diagnosed via fundus and fluorescein angiographic appearance. The etiology and pathophysiology are not fully understood; however, there may be an association with an infectious etiology. This article presents two cases of hiv-positive patients in whom central serous chorioretinopathy developed and discusses the possible relationship between the two cases. The differential diagnosis, clinical features, angiographic appearance, management options, and proposed etiologies of CSC will be presented. case reports: A 34-year-old black man hiv reported to the eye clinic with decreased vision in his right eye. A diagnosis of central serous chorioretinopathy (CSC) was made on the basis of the clinical and fluorescein appearance. He is currently being monitored for resolution. A 44-year-old black man with profoundly compromised immunity also came to the eye clinic with CSC and hiv retinopathy. He later progressed to CMV retinitis and subsequently died. CONCLUSION: Although considered in many cases to be idiopathic, central serous chorioretinopathy has been associated with infectious etiologies, one of which could be hiv.- - - - - - - - - - ranking = 0.2keywords = ocular (Clic here for more details about this article) |
