“…The parasite also enters the eye with some frequency. In a review of 484 cases of eosinophilic meningitis, Punyagupta and colleagues [131] noted that 47 (16%) of the cases had reported ocular involvement, and in 7 cases an actively motile worm (most probably A. cantonensis ) was visualized and removed from the anterior chamber of vitreous of the eye [132,133]. Human ocular infections by larval rat lungworm have been reported in several countries in Southeast Asia [134-143] and, they likely will continue to be reported wherever the parasite occurs, including in new geographical areas such as the Caribbean [144].…”

Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.Homines amplius oculis, quam auribus creduntSeneca Ep 6,5Men believe their eyes more than their ears

“…Common ocular parasites are Toxocara, Onchocerca, Wuchereria, Ankylostoma, Loa, Dirofilaria and Angiostrongylus 1. Ocular angiostrongyliasis has been reported from Vietnam, Sri Lanka, Japan, Thailand, Indonesia and Papua New Guinea 2. It has never been reported as a cause of hypertensive uveitis.…”

A middle-aged Asian gentleman presented with four weeks′ history of recurrent redness, pain and deterioration of vision in his right eye. He was diagnosed with chronic, unilateral, granulomatous hypertensive uveitis. During one of the serial examinations a single, off-white, extremely motile, thread-like worm about 15 mm long was noted in the anterior chamber. Surgical retrieval of the worm was unsuccessful. The worm disappeared in the eye and was never seen again. Patient suffered from chronic waxing and waning granulomatous inflammation with uncontrolled high intraocular pressure despite treatment. The vision dropped down to no perception of light. Therapeutic success in such patients depends upon early and complete surgical removal of the worm, which could be a real challenge as worms are highly motile and only visible sporadically, as in this case. Ocular parasitosis should be kept in mind as a differential diagnosis in treating non-responsive chronic hypertensive granulomatous inflammation, especially if the patient is of Southeast Asian origin or has recently visited the region.

Angiostrongylus cantonensis is also called the rodent lung worm. It was first discovered in 1935 by Chen in Rattus rattus, in Canton, China. The rodent is the definitive host while infected mollusks, snails and crabs act as the intermediate hosts. Humans are infected by the 3rd stage larvae, either by eating undercooked intermediate hosts or by consuming vegetables.(1) It is a delicate nematode reported in Asia Pacific region most commonly in South-east Asia and has been reported from Taiwan, Thailand, Indonesia, Vietnam and Sri Lanka.(2) Anterior chamber angiostrogyliasis is extremely rare, and no previous case of ocular angiostrogyliasis from India could be found on Medline search. We report a new technique in the removal of the actively motile thread-like worm by paralysing it with intracameral preservative free lidocaine, which aids in the easy removal of the intact worm.
