Ocular parasitoses and their immunology.

Parasitic infections of the eye are a major cause of ocular diseases in many parts of the globe. The causative agents of ocular parasitoses include several species of unicellular protozoan and metazoan helminth parasites, which have a natural predilection for and utilize the eye as their habitat. At times ocular invasion by accidental or uncommon parasites may result in infections of unusual nature. In this review the authors discuss the various parasitic causal agents of eye diseases and the current status of immunology against ocular parasitoses.
