Human ocular thelaziasis: A case report from Manipur, India

This is a case report of asymptomatic human ocular thelaziasis that was discovered accidentally just before a planned cataract surgery. A 69-year-old farmer from a rural area presented to the outpatient department of Ophthalmology with diminished vision in both the eyes, which was diagnosed as bilateral cataract. On the day of operation of the right eye, after instillation of 4% lignocaine hydrochloride eyedrops, a small, motile, chalky white, translucent worm was removed from the conjunctiva. It was morphologically identified as a female Thelazia callipaeda (T. callipaeda).
