Information about the causes of endogenous uveal tract infection has been derived from a variety of sources. Microscopic examination and/or culture of infected uveal tissue obtained from enucleated eyes has revealed that potentially pathogenic organisms may be demonstrated in the lesions. The following have been so demonstrated, each in at least one case in which it was presumed to be the cause of the uveitis.
Cytomegalic inclusion disease17
Fly larvae 16
In rare instances, pathogenic organisms have been isolated from fluid aspirated from the infected eye. Leptospira,18Toxoplasma,20 herpes simplex virus,21 and cytomegalic inclusion virus19 have been cultured from anterior chamber fluid, and Toxoplasma from subretinal fluid20 obtained from patients with uveitis.
