1/104. Presumed ocular bartonellosis.BACKGROUND: The spectrum of diseases caused by bartonella henselae continues to expand and ocular involvement during this infection is being diagnosed with increasing frequency. methods: The clinical features and visual prognosis for 13 patients with intraocular inflammatory disease and laboratory evidence of bartonellosis were investigated. There were nine patients with neuroretinitis and four with panuveitis with positive antibody titres against B henselae determined by an enzyme immunoassay (IgG exceeding 1:900 and/or IgM exceeding 1:250). RESULTS: Positive IgG levels were found for eight patients and positive IgM levels for five. Despite animal exposure of 10 patients, only two (IgG positive) cases had systemic symptoms consistent with the diagnosis of cat scratch disease. Pathological fluorescein leakage of the optic disc was observed in all affected eyes. At 6 months' follow up, 3/18 (17%) affected eyes had a visual acuity of less than 20/100, owing to optic disc atrophy and cystoid macular oedema. 12 patients (17 eyes) were treated with antibiotics; visual acuity improved two or more Snellen lines for 9/17 (53%) eyes. CONCLUSIONS: The possibility of B henselae infection should be considered in patients with neuroretinitis and panuveitis (especially in cases with associated optic nerve involvement) even in the absence of systemic symptoms typical for cat scratch disease.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/104. Asymptomatic unilateral microembolic retinopathy secondary to percutaneous transluminal coronary angioplasty.BACKGROUND: Percutaneous transluminal coronary angioplasty (PTCA) for the treatment of coronary artery disease has increased in frequency as technological advances have made the procedure more effective and cost-efficient. In spite of the number of procedures that have been performed, ocular complications have rarely been reported. CASE REPORT: A case of asymptomatic unilateral microembolic retinopathy one month after PTCA is presented. Embolic events to the retinal circulation and their relationship to invasive cardiac procedures is discussed. CONCLUSIONS: The embolic ocular complications of PTCA is probably underestimated due to the lack of symptoms from the partial occlusion of the larger retinal arteries and the total occlusion of the remote smaller vessels.- - - - - - - - - - ranking = 0.33333333333333keywords = ocular (Clic here for more details about this article) |
3/104. Demonstration of Bartonella grahamii dna in ocular fluids of a patient with neuroretinitis.We describe the clinical and laboratory features of a 55-year-old human immunodeficiency virus-negative female patient who presented with bilateral intraocular inflammatory disease (neuroretinitis type) and behavioral changes caused by a Bartonella grahamii infection. diagnosis was based on the PCR analysis of dna extracted from the intraocular fluids. dna analysis of the PCR product revealed a 100% identity with the 16S rRNA gene sequence of B. grahamii. The patient was successfully treated with doxycycline (200 mg/day) and rifampin (600 mg/day) for 4 weeks. This is the first report that demonstrates the presence of a Bartonella species in the intraocular fluids of a nonimmunocompromised patient and that indicates that B. grahamii is pathogenic for humans.- - - - - - - - - - ranking = 1.1666666666667keywords = ocular (Clic here for more details about this article) |
4/104. 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 = 0.83333333333333keywords = ocular (Clic here for more details about this article) |
5/104. 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 = 0.16666666666667keywords = ocular (Clic here for more details about this article) |
6/104. Diffuse toxoplasmic retinochoroiditis as the initial manifestation of acquired immunodeficiency syndrome.Toxoplasmic retinochoroiditis is an important opportunistic retinal infection in human immunodeficiency virus (hiv)-infected patients. It may present as diffuse necrotizing retinochoroiditis instead of a focal lesion and may be the initial manifestation of hiv infection. A 50-year-old heterosexual man presented with blurred vision in his left eye of 3 months' duration. Fundus examination revealed diffuse necrotizing retinochoroiditis, mainly at the posterior pole, with marked vitritis in the left eye. Serologic studies and aqueous fluid antibody titers indicated recent toxoplasmic infection. Positive enzyme immunoassays (EIA) and Western blot tests proved hiv infection. The retinochoroiditis and vitritis improved after an antitoxoplasmic regimen with trimethoprim-sulfamethoxazole (TMP-SMX). Nonetheless, toxoplasmic encephalitis developed 6 months after the onset of ocular toxoplasmosis and responded well to TMP-SMX. This is the first case of toxoplasmic retinochoroiditis as the initial manifestation of AIDS reported in taiwan. We suggest that toxoplasma infection should be included in the differential diagnosis of diffuse necrotizing retinochoroiditis and vitritis. We also recommend that adults with newly diagnosed ocular toxoplasmosis be screened for hiv infection.- - - - - - - - - - ranking = 89.021920702235keywords = ocular toxoplasmosis, toxoplasmosis, ocular (Clic here for more details about this article) |
7/104. Ischemic retinitis as a result of acute episodic blood loss.Acute episodic blood loss leads to a sudden change in the haemodynamics leading to a number of ocular and systemic effects. Occurrence of ischemic retinitis secondary to acute blood loss is of a very rare occurrence. This communication presents a case of infarction of the nerve fibre layer secondary to acute blood loss in a 55-year-old male.- - - - - - - - - - ranking = 0.16666666666667keywords = ocular (Clic here for more details about this article) |
8/104. Hypopyon in a patient with presumptive diffuse unilateral subacute neuroretinitis.PURPOSE: To report a case of diffuse unilateral subacute neuroretinitis (DUSN) that developed an acute iridocyclitis with hypopyon. methods: Case report. We describe a 21-year-old male with clinical diagnosis of DUSN who developed a sudden and severe acute iridocyclitis with hypopyon after one year of follow-up that resolved after treatment with systemic corticosteroids. RESULTS: anterior chamber paracentesis was performed and cultures were negative. Cytologic studies disclosed the presence of eosinophils. CONCLUSIONS: This unusual ocular finding may be related to the death of the nematode in the course of the disease.- - - - - - - - - - ranking = 0.16666666666667keywords = ocular (Clic here for more details about this article) |
9/104. An ocular cat-scratch disease patient positive for cytoplasmic anti-neutrophil cytoplasmic antibody.BACKGROUND: We report a case of ocular cat-scratch disease with permanent vision reduction in a patient who was cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA) positive. methods: Case report and review of the literature. RESULTS: While taking steroids and antibiotics, a 52-year-old man with uveitis associated with cat-scratch disease developed retinal vein occlusion and a macular exudate. His final visual acuity was poor because of residual macular degeneration and optic atrophy. serum C-ANCA increased and decreased in parallel with ocular inflammatory activity. CONCLUSION: C-ANCA is an indicator of vasculitis and may be useful as an indicator of severe cat-scratch disease.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
10/104. Identifying live nematodes in diffuse unilateral subacute neuroretinitis by using the scanning laser ophthalmoscope.OBJECTIVE: To describe use of the scanning laser ophthalmoscope (SLO) to identify live nematodes in patients with diffuse unilateral subacute neuroretinitis. methods: Infrared, red, and blue illumination (780, 633, and 488 nm, respectively) in an SLO were used to image and evaluate functional retinal status in patients with late-stage diffuse unilateral subacute neuroretinitis. An examination to identify live nematodes was performed in the affected eyes. RESULTS: Using blue illumination, the ocular fundus appeared dark and provided a high-contrast background for the white image of the worm. The red laser was used to perform red-on-red perimetry. We also used perimetry stimulus to stimulate the worm's movement and pinpoint its location. We precisely defined the relation between the fixation point and the worm to plan accurate laser treatment. The infrared laser is safe and comfortable for prolonged examination. Using the SLO, several physicians simultaneously visualized the ocular fundus. Video output from the SLO provided temporal information, excellent for enhancing detection of worms, which was displayed dynamically on video. CONCLUSIONS: Although examination with a fundus contact lens by skilled ophthalmologists is the method of choice, the SLO provides a new examination modality with distinct advantages for identifying live worms in young patients with diffuse unilateral subacute neuroretinitis.- - - - - - - - - - ranking = 0.33333333333333keywords = ocular (Clic here for more details about this article) |
