1/103. bartonella henselae infection associated with peripapillary angioma, branch retinal artery occlusion, and severe vision loss.PURPOSE: To report atypical clinical features of bartonella henselae neuroretinitis treated with combination antibiotics. METHOD: Case report. RESULTS: A 20-year-old man with a positive B. henselae titer developed a unilateral neuroretinitis, a large peripapillary angiomatous lesion, branch artery occlusion with ischemic maculopathy, and vision loss that failed to improve with clindamycin. Treatment with doxycycline and rifampin led to rapid clinical improvement. The severe vision loss in this case is atypical. CONCLUSIONS: Ocular findings associated with B. henselae infection may include retinal angiomatous lesion and branch retinal artery occlusion. doxycycline and rifampin were successful in treating the infection.- - - - - - - - - - ranking = 1keywords = vision (Clic here for more details about this article) |
2/103. Pachymeningitis and optic neuritis in rheumatoid arthritis: MRI findings.Rheumatoid arthritis is a systemic disease in which cerebral and eye involvement is neither common nor fully understood. Although it is rarely the cause of pachymeningitis and optic neuritis, rheumatoid arthritis should always be kept in mind in these two conditions. We present a 52-year-old male with an 8 month history of rheumatoid arthritis who was referred to the neurology department with headache and decreasing vision and was diagnosed as having rheumatoid pachymeningitis and optic neuritis on the basis of MRI findings.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
3/103. Adrenal cortical carcinoma metastatic to the brain in a child.A 9-year-old girl presented with profoundly decreased vision in both eyes and bilateral optic disc swelling. magnetic resonance imaging showed a large intraventricular mass. Excisional biopsy diagnosed metastatic adrenal cortical carcinoma (ACC). This is, to the best of our knowledge, the first reported case of ACC metastatic to the brain in a child. It also illustrates the importance of differentiating optic neuritis from papilledema in children.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
4/103. cysticercosis of the optic nerve.cysticercosis of the optic nerve has been reported only twice in the literature. A case of optic nerve cysticercosis in a 50-year-old woman with atypical optic neuritis is reported. Computerized tomography showed a thickened left optic nerve with a ring-enhancing lesion containing an eccentric nodule. An enzyme-linked immunosorbent assay test for cysticercosis further established the diagnosis. The patient was treated with oral prednisolone and albendazole, with no improvement in vision.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
5/103. prevalence of serologic evidence of cat scratch disease in patients with neuroretinitis.OBJECTIVE: To determine the prevalence of bartonella henselae seropositivity in patients with a clinical diagnosis of neuroretinitis. DESIGN: Retrospective, clinic-based, cross-sectional study. PARTICIPANTS: Eighteen consecutive patients seeking treatment at the Casey eye Institute from November 1993 through November 1998 who had neuroretinitis. methods: The billing and photographic records of the Casey eye Institute were searched for patients with a primary or secondary diagnosis of neuroretinitis or Leber's idiopathic stellate neuroretinitis. charts were then reviewed to determine the results of B. henselae antibody titers and other pertinent clinical information. MAIN OUTCOME MEASURES: Results of B. henselae serologic testing. RESULTS: Fourteen of 18 patients with neuroretinitis had serologic studies. Nine of the 14 tested patients (64.3%) were found to have elevated IgM or IgG for B. henselae, suggesting current or past infection. patients with positive serologic analysis results tended to have worse vision at presentation. There were no other obvious differences between seropositive and seronegative groups in this study, including duration or quality of recovery. CONCLUSIONS: At our tertiary care ophthalmology institution, most tested patients with neuroretinitis had evidence of past or present cat-scratch disease based on positive serologic analysis for B. henselae, a much greater prevalence than is expected to be found in the general population or in patients with idiopathic uveitis. Further study is indicated to clarify the prevalence of cat-scratch disease in neuroretinitis and the role and efficacy of antibiotics in treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
6/103. optic neuritis after bee sting.The purpose of this report is to document an unusual case of fully recovered vision after optic neuritis caused by bee sting. A 46-year-old man presented with sudden visual loss after being stung by a bee on the left conjunctiva. He developed optic disc swelling and there was a delay in the P100 wave of the pattern visual evoked potential (VEP). The patient received acute treatment, with intravenous methylprednisolone followed by oral prednisolone. Two days later, visual acuity in the left eye was recovered to 20/20 and P100 latency in pattern VEP was also normalized. Furthermore, visual field and color vision tests revealed no remaining abnormalities. This case suggests that early corticosteroid treatment is effective in optic neuritis caused by bee sting.- - - - - - - - - - ranking = 0.33333333333333keywords = vision (Clic here for more details about this article) |
7/103. optic nerve sheath fenestration for a reversible optic neuropathy in radiation oncology.To the authors' knowledge, there is a paucity of published accounts of management of radiation-induced optic neuropathy (RION) by optic nerve sheath fenestration (ONSF) in the conventional medical literature. With higher doses of radiation being given by using conformal techniques, more radiation-induced optic neuritis and neuropathy will be identified. We report here the successful use of ONSF to restore vision to three consecutive patients with pending anterior RION, and the importance of early identification and intervention in these potentially reversible cases.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
8/103. optic neuritis in children.PURPOSE: To describe the clinical characteristics of optic neuritis in children, including final visual acuity and development of multiple sclerosis (MS). methods: charts were reviewed of all patients < 15 years of age who presented with optic neuritis to the Bascom Palmer eye Institute or the Miami Children's Hospital between 1986 and 1998. RESULTS: Fifteen patients were identified. There was a slight female predilection in the study group (60%), with a mean age of 9.8 years at presentation. A preceding febrile illness within 2 weeks of visual symptoms was reported in 66% of patients. Initial visual acuity ranged from 20/15 to no light perception. Involvement was bilateral in 66% of patients, and disc swelling was present in 64% of involved eyes. Of the patients who underwent magnetic resonance imaging, 33% had focal demyelinating lesions in the brain, and 63% of affected nerves were enlarged or enhanced with gadolinium. Eleven patients were treated with intravenous steroids. Final visual acuity was > or = 20/40 in 58.3% of eyes. Thirty percent of the patients had vision of finger counting or worse. Four (26%) patients developed MS. The mean age of patients with MS was 12 years, compared with 9 years in children who did not develop MS. patients with unilateral involvement had an excellent visual prognosis (100% > 20/40), but a higher rate of development of MS (75%). Two patients had positive serology for lyme disease. CONCLUSIONS: optic neuritis presents differently in children than in adults. Children typically have bilateral involvement with papillitis following an antecedent viral illness. Although visual prognosis is poorer in children than adults, the development of MS is less common in children. Children who present with unilateral involvement have a better visual prognosis; however, they also develop MS at a greater frequency than children with bilateral involvement. patients who developed MS were, on average, older at presentation with optic neuritis than those who did not develop MS.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
9/103. optic neuritis in herpes zoster ophthalmicus.BACKGROUND: optic neuritis in herpes zoster ophthalmicus (HZO) has been reported rarely. We report two cases of HZO optic neuritis with detailed magnetic resonance imaging study and treatment responses. CASES: One patient presented with anterior optic nerve involvement, and the second presented with retrobulbar optic neuritis. Contrast enhanced T(1)-weighted images were obtained in these 2 patients. Intravenous acyclovir and oral prednisolone were given simultaneously. OBSERVATIONS: magnetic resonance imaging revealed peripheral enhancement of the optic nerve sheath complex on T(1)-weighted scan. Both patients recovered their vision within 3 months following the start of treatment. CONCLUSIONS: magnetic resonance imaging is helpful for the diagnosis of HZO optic neuritis. Systemic acyclovir and steroid are effective in the treatment of HZO optic neuritis.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
10/103. Reversible blindness resulting from optic chiasmitis secondary to systemic lupus erythematosus.OBJECTIVE: To report the diagnosis, radiologic findings, and therapy of a 51-year-old female with systemic lupus erythematosus (SLE) who, while on hydroxychloroquine maintenance therapy, presented with a junctional scotoma indicative of chiasmal disease. This visual loss developed after she had been tapered off corticosteroids. MATERIALS AND methods: An interventional case report of a female that was given acute therapy with 1-gram daily of intravenous methylprednisolone sodium succinate for 5 days, followed by maintenance methotrexate and a slow taper of oral prednisone. magnetic resonance imaging (MRI) scans, visual acuity, color vision, and threshold visual fields were performed. RESULTS: The MRI scan showed chiasmal involvement, which may occur in SLE in absence of any other evidence of systemic activity. Therapy led to visual function returning to 20/20 OD and 20/20 OS, with normal Ishihara plates OU and only minimal paracentral depressions OU. She has been able to be weaned off prednisone while on methotrexate maintenance. CONCLUSIONS: Chiasmal involvement may occur in SLE in absence of any other evidence of systemic activity. maintenance with hydroxychloroquine may not be adequate to prevent this rare cause of visual loss in SLE. Aggressive therapy of chiasmal involvement in SLE, even when the visual loss is profound, may lead to visual restoration, which was virtually complete in this case. methotrexate may be an alternate agent for patients who break through with optic neuropathy while on hydroxychloroquine.- - - - - - - - - - ranking = 0.16666666666667keywords = vision (Clic here for more details about this article) |
