| Titre | Ocular Manifestations of West Nile Virus Infection |
| Abstract Nr. | P010 |
| But | To describe prospectively the ocular manifestations of West Nile virus (WNV) infection. |
| Méthodes | Twenty nine patients with serologically confirmed WNV infection underwent a detailed ophthalmic examination, and fluorescein angiography. |
| Résultats | A typical multifocal chorioretinitis was observed in 20 of 29 patients (69%) bilaterally at presentation and developed later during follow-up in 3 patients (10.3%). Other fundus findings included intraretinal hemorrhages (72.4%), white-centered retinal hemorrhages (24.1%), focal retinal vascular sheathing (10.4%), diffuse retinal arterial sheathing (3.4%), retinal vascular leakage (17.2%) optic disc swelling (6.9%), optic disc staining (20.7%), segmental zones of retinal pigment epithelium changes (3.4%), and nonproliferative diabetic retinopathy (24.1%). Other findings included anterior uveitis (13.8%), subconjunctival hemorrhage (6.9%), sixth nerve palsy (3.4%), and nystagmus (3.4%). Ocular findings related to WNV disease had a self-limited course in all cases. |
| Conclusion | Chorioretinal involvement is common in patients with acute WNV infection. The unique pattern of multifocal chorioretinitis in patients with systemic symptoms suggestive of WNV can help establish the diagnosis while serologic testing is pending. |
