Online published on 5 November, 2018. Abstract Eight horses were presented with history of impaired vision, corneal opacity, epiphorea, blepharospasm, ocular discomfort and lacrimation of affected eyes since last 7–10 days. Examination of affected eyes revealed vigorous wavy movement of white thread like worm in aqueous humour of anterior chamber in all horses. Diagnosis was based on correlation with history, clinical signs and worm activity in aqueous humour and confirmed by removal of worm from affected eye. The worm was identified as Setaria species based on microscopic examination. All horses were restrained in lateral recumbency followed by auriculo palpebral nerve block. The affected eye was irrigated with normal saline solution followed by 4–5 drops of 2% Lignocaine hydrochloride were instilled as topical anesthesia. A 16 guage neddle was inserted in anterior chamber of eye through 4 o'clock position of cornea/corneo scelaral junction approximately 1 mm away from the limbus as the worm appeared near the site. The eye worm was escaped through needle hub due to aqueous humour pressure. After removal of worm, Flunixin meglumine @ 1.1 mg/kg b. wt. intravenous on first day and topical application of Gentamicin and Dexamethasone eye drop 4q 6 h for 20–30 days was undertaken to avoid concurrent infection and inflammatory changes in eyes. All eight equines showed successful management of removal of Setaria species from anterior chamber of eye with paracentesis of 16 guage needle without any post-operative complications.
