1/8. Vitritis and chorioretinitis in a patient with west nile virus infection.OBJECTIVE: To describe the visual outcome, fundus appearance, and fluorescein angiographic findings of a patient diagnosed as having acute west nile virus infection. methods: We conducted comprehensive eye examinations, including visual acuity testing and slitlamp and fundus examinations, along with fluorescein angiography at the initial and follow-up visits. RESULTS: A 62-year-old white woman had a 2-week history of floaters in her left eye along with symptoms of fatigue, a left-sided frontal headache, and a low-grade fever. She was found to have anterior uveitis, vitritis, and nonnecrotizing chorioretinitis in her left eye with similar but milder findings in the right eye. The anterior uveitis responded to topical steroids. Because of continued fevers and fatigue, a serologic test for west nile virus immunoglobulin m was performed, and the results were found to be positive for this disease. CONCLUSION: These unique eye findings, along with associated systemic signs and symptoms, can potentially indicate infection with the west nile virus.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
2/8. west nile virus-associated optic neuritis and chorioretinitis.PURPOSE: To report the new ocular and neurologic features of west nile virus (WNV) meningoencephalitis. DESIGN: Observational case report. methods: A 55-year-old woman presented with headache, stiff neck, visual loss, and fever 10 days after a weekend camping trip. Examination revealed vitritis, creamy yellow circular chorioretinal lesions, and peripheral visual field loss. RESULTS: Laboratory investigation indicated the patient was suffering from WNV meningoencephalitis with neuro-ocular involvement. CONCLUSION: Ophthalmologists and infectious disease specialists should recognize that the WNV infection spectrum may include ophthalmic findings, specifically optic neuritis and multifocal chorioretinitis.- - - - - - - - - - ranking = 0.5keywords = fever (Clic here for more details about this article) |
3/8. Ocular manifestations of dengue fever.PURPOSE: To evaluate ocular manifestations associated with dengue fever. DESIGN: Retrospective case series and literature review. methods: Clinical records of patients with dengue fever who subsequently had ocular symptoms and signs develop were reviewed. The clinical presentation and ocular complications were evaluated. RESULTS: Six patients, 5 females and 1 male, were seen with a sudden decrease in vision 6 to 7 days after the initial manifestations of dengue fever were identified. The diagnosis was confirmed by detection of dengue-specific IgM antibodies (IgM enzyme-linked immunoassay). The presenting best-corrected visual acuity ranged from 20/30 to counting fingers, and ocular involvement was bilateral but asymmetric in 5 cases and unilateral in 1 case. Fundus findings included small, intraretinal, whitish lesions, with localized retinal and retinal pigment epithelium (RPE) disturbance, small dot hemorrhages, and vascular sheathing around the macula and the papillomacular bundle. fluorescein angiography showed arteriolar focal knobby hyperfluorescence at the macula with mild staining of the vascular walls and leakage at the level of the RPE. All 5 cases that had indocyanine green angiography done showed early diffuse choroidal hyperfluorescence with late silhouetting of the larger choroidal vessels. Five patients received steroid therapy: 1 topical, 2 periocular, and 2 oral. Over 2 to 4 months, RPE discoloration was observed over the affected areas. After the acute episode, 3 patients showed partial recovery of vision, and in the remaining patients, the visual acuity remained stable. CONCLUSIONS: Ocular complications associated with dengue fever are rare but may result in permanent visual impairment.- - - - - - - - - - ranking = 24341.057202663keywords = dengue fever, dengue, fever (Clic here for more details about this article) |
4/8. Ocular manifestations in Dengue fever.PURPOSE: To report a case of Dengue fever resulting in permanent visual loss in both eyes due to retinal capillary occlusion. methods: Case report. RESULTS: Severe permanent visual loss occurred in a patient with Dengue fever. Dilated fundus exam showed vascular sheathing with associated retinal hemorrhages at the equator and cotton wool spots in the maculae of both eyes. fluorescein angiography revealed areas of capillary nonperfusion at the equator and in the macula. The diagnosis of Dengue fever was confirmed by serology detecting IgM antibodies to the dengue virus. CONCLUSION: Ocular abnormalities may be seen in patients with Dengue fever, therefore ophthalmoscopy should be performed in patients presenting with severe forms of the disease.- - - - - - - - - - ranking = 4keywords = fever (Clic here for more details about this article) |
5/8. Electrophysiological findings in patients with dengue-related maculopathy.OBJECTIVE: To assess visual function in patients with dengue maculopathy using electrophysiological tests. methods: Fifteen consecutive patients with dengue fever who experienced vision loss between July 2004 and July 2005 were included in this review. Full-field electroretinograms (ERG), pattern ERGs, and multifocal ERGs were performed. RESULTS: The most common electrophysiological finding (60%, 9/15) was a normal or mildly abnormal full-field ERG with reduced pattern ERG P50 amplitude and abnormal mfERG. Typically, multifocal ERG demonstrated a focal area of decreased macular response (especially between the fovea and optic nerve). Pattern ERG suggested normal optic nerve function in all but 1 case. Four patients had more severely reduced full-field ERG responses with reduced a-wave amplitude (suggestive of photoreceptor dysfunction), 3 of whom had an electronegative maximal response (suggestive of additional postreceptor dysfunction). Repeat multifocal ERG showed little change in 7 patients and incomplete resolution in 2 patients over 3 to 10 months. CONCLUSION: Retinal dysfunction associated with dengue maculopathy was localized mainly around the foveal region. It appeared to affect the outer and middle retina more severely with relative sparing of the inner retina. Retinal dysfunction may persist for several months. Longer follow-up is required to determine whether these changes are permanent.- - - - - - - - - - ranking = 4094.687903814keywords = dengue fever, dengue, fever (Clic here for more details about this article) |
6/8. Coxsackievirus B3-associated panuveitis.A 29-year-old woman suffered from headaches, diarrhoea, and high grade fever followed by a unilateral retinal vasculitis, papillitis, and chorioretinitis. Abnormal electrocardiographic findings and antibody titre dynamics strongly suggested a coxsackievirus B3 infection. With respect to prior observations on coxsackievirus B group associated uveitis this viral infection may be considered in patients with well defined extraocular manifestations and uveitis.- - - - - - - - - - ranking = 0.5keywords = fever (Clic here for more details about this article) |

8/8. Hemorrhagic fever (puumala virus infection) with ocular involvement.BACKGROUND: puumala virus infection (nephropathia epidemica) is a disease in the group of hemorrhagic fevers with renal syndrome causing ocular manifestations, e.g. transient myopia and changes in intraocular pressure. PATIENT AND methods: Comprehensive and repeated ophthalmic examinations of a previously healthy 35-year-old woman with acute puumala virus infection were performed. Special attention was paid to ophthalmic A-scan ultrasound measurements and simultaneous blood chemistry tests. RESULTS: The ocular manifestations of this patient's illness included transient myopia, low intraocular pressure, conjunctival hemorrhages and changes of intraocular dimensions. There was forward movement of the anterior diaphragm and thickening of the crystalline lens, which occurred simultaneously with prominent fluctuations in the electrolyte balance, especially potassium. CONCLUSIONS: The observed changes in intraocular dimensions may have been caused by simultaneous fluctuations in electrolyte and osmotic balance, which could explain the myopic shift. The symmetry of the ocular measurements implied a systemic infection as the underlying reason for the ophthalmic symptoms and signs.- - - - - - - - - - ranking = 2.5keywords = fever (Clic here for more details about this article) |
