Abstract
Parasites are a group of eukaryotic organisms that may be free‑living or form a symbiotic or parasitic
relationship with the hosts. Consisting of over 800,000 recognized species, parasites may be unicellular
(Protozoa) or multicellular (helminths and arthropods). The association of parasites with human population
started long before the emergence of civilization. Parasitic zoonotic diseases are prevalent worldwide
including India. Appropriate epidemiological data are lacking on existing zoonotic parasitic diseases,
and newer diseases are emerging in our scenario. Systemic diseases such as cysticercosis, paragonimiasis,
hydatidosis, and toxoplasmosis are fairly common. Acquired Toxoplasma infections are rising in
immune‑deficient individuals. Amongst the ocular parasitic diseases, various protozoas such as Cystoidea,
trematodes, tissue flagellates, sporozoas etc. affect humans in general and eyes in particular, in different
parts of the world. These zoonoses seem to be a real health related problem globally. Recent intensification
of research throughout the world has led to specialization in biological fields, creating a conducive situation
for researchers interested in this subject. The basics of parasitology lie in morphology, pathology, and with
recent updates in molecular parasitology, the scope has extended further. The current review is to address
the recent update in ophthalmic parasites with special reference to pathology and give a glimpse of further
research in this field.
