Ocular manifestations of systemic disease: ocular parasitosis

PURPOSE OF REVIEWTo highlight recent advances in basic research, diagnostic as well as therapeutic advances in ocular parasitosis and to evaluate their application in medical practice. RECENT FINDINGSKnowledge relating to immunoreactivity in ocular parasitology has grown impressively in past few years. The outcome of infection is the result of a set of interactions involving host and parasite genetic background, environmental and social factors. Immunopathogenesis of parasite-mediated host cell lysis is better understood. Studies on newer drugs with cophylogenetic techniques are in horizon. There are success stories on control of transmission in some countries. SUMMARYMuch has been achieved; however, much more effort is needed in the area of translational research from bench to bedside. There is a need to enhance the awareness of risk factors of parasitic diseases in the population. Newer molecular diagnostic techniques need to be standardized for field application. Steps needed to be taken by the ophthalmologist when a parasite is seen in ocular tissues including identification, search for systemic involvement, treatment for elimination and sequelae and public health notification. Lack of methodological uniformity in management emphasis the need for standardization including construction of management algorithm for ophthalmologists.
