Thelazia is a nematode (Spirurida) that can parasitize the mammalian conjunctival sac. This is the first reported case of ocular. Thelazia callipaeda infestation in Taiwan. A 41-year-old woman experienced swelling, itching sensation and occasional blurred vision of the right eye 2 weeks after a small group of flies swarmed her eye while she was hiking. Her symptoms were first misdiagnosed as allergic conjunctivitis at a local medical clinic. During her first visit to our outpatient department, five white thread-like living worms were discovered on the superior and inferior fornices. The worms were cream-colored, slender and approximately 1 cm in length. Follicular and papillary conjunctivitis was noted in her right eye. After removing the worms, the symptoms resolved and no other worms were found in the following 2 months. This case is a remainder to physicians that parasitic infestation should be included in the differential diagnoses of ocular itching, conjunctivities, and blurred vision after insect contact.

Two male patients presented with unilateral blurred vision. A small motile worm was found in the vitreous cavity in both cases. In one case, another dead, disintegrated worm was noted in the inferior portion of the vitreous cavity. On each eye, vitreous surgery was performed and the worm was removed by an aspirator. Both worms were identified as Angiostrongylus cantonensis. Since both patients had no signs of meningitis, lumbar puncture was not done. Long-term follow-up confirmed the benefit and safety of the vitreous surgery. Fluorescein angiography revealed severe pigmentary alteration, probably from inflammation of the choroid and retina due to subretinal migration of the worm prior to access into the vitreous cavity.
