Ocular complications of Rift Valley fever outbreak in Saudi Arabia

Rift Valley fever was associated with major ocular morbidity. Ocular manifestations of RVF occurred with a relatively higher frequency than reported up to now and were not limited to severe infections. Rift Valley fever affects the uvea and posterior chorioretinal area and is associated with permanent visual loss resulting from macular and paramacular scarring, vascular occlusion, and optic atrophy. The study demonstrated for the first time that transient nongranulomatous anterior uveitis is associated with RVF.
