The study of parasites that transmit disease to humans and cause ophthalmic abnormalities is known as ocular parasitology. Parasitology began as a tropical step-sister to medicine, but in these days of global awareness, it has evolved into a well-known scientific discipline in its own right. Parasitology has witnessed tremendous change in the last decade.

The pathogenic organisms of parasitic disorders rely on reproduction as their primary mode of life in the ultimate host. Many progenies are required to overcome mortality during organism transmission and pass on the reproductive character to the following generation. The host is denied of vital resources and nutrients that the parasites need for reproduction. The result of these alterations is small or significant damage to host tissue, and if they grow more severe, there is apparent deterioration of the host, which is then referred to as having systemic parasitism involvement.

Pathological changes caused by parasite infections may also result in a variety of defects in the homeostatic regulating mechanisms, which primary function is to protect the host against infections. Many distinct parasite species have diverse impacts on the host response; hence, pathology, immunology, and biology are intertwined and upset the host's homeostasis.

Under background illumination, the complete interior anatomy, including the gut, spine, and striations, may be promptly detected, and the rapid diagnosis can be given to the surgeons. The complete diagnostic process might take 5–10 minutes from the moment the material is received. Because the care protocols of various worms vary, an immediate diagnosis can aid in the overall management of the patient. These were compared to the parasites' wet-mount preparation. To confirm the diagnosis, a parasitologist's opinion was sometimes required. A parasitic organism's connection with its host's immune system is exceedingly complicated. With recent progress, many diseases of ocular parasites producing infections in the eye and adnexa have been identified.

Parasitic worms are responsible for some of the world's most deadly and chronic infectious diseases affecting both humans and animals. Ocular damage can be produced directly by an infectious pathogen or indirectly by toxic byproducts, an immune response triggered by infection, or ectopic parasitism in preadult or adult stages. Severe panuveitis with no known aetiology that is frequently unilateral. The condition manifested itself acutely, with red eyes and a white pupillary reaction, as well as occasional discomfort. The anterior chamber has fibrinous uveitis with hypopyon. Histopathology indicated a significant inflammatory response with a predominance of lymphocytes and plasma cells. A retrolenticular mass was formed by drawing up the retina. The specimens' of the SEM revealed Russell bodies and plasma cells. Varicella zoster virus was discovered in the intraocular fluid of a patient with seasonal hyperacute panuveitis.


Parasitic diseases are common in many regions of the world, and parasitologists, microbiologists, and pathologists must isolate these organisms specifically. Ocular parasites are significant because they inflict serious damage to the eye's exterior and interior tissues. The removal of the live worm is critical in certain parasitic invasions since killing these parasites with antimicrobial drugs can induce severe intraocular inflammation and infection, such as endophthalmitis. Several researches have proven a novel way for identifying living parasites under compound microscope objectives and digitally photographing them. Under background illumination, qualified ocular pathologists and microbiologists may observe the complete interior anatomy and give a fast diagnosis to the surgeons.
