Retinitis occurs when viruses, bacteria, fungi, or parasites invade the retina. The infecting agent travels to the eye via the bloodstream. Rapid and sometimes severe loss of vision may occur. One or both eyes may be involved. Symptoms may also include pain and light sensitivity.
EvaluationA complete eye examination, including dilation, is necessary to visualize the retina and diagnose retinitis.
In addition, fluorescein angiography is useful to evaluate the severity of the infection and assess retinal, vascular, and optic nerve involvement.
