ABSTRACT
Ocular trauma accounts for a significant proportion of cases in any emergency eye outpatient department. There are very few cases reporting ocular injuries after leech exposure. Leeches are annelids belonging to the subclass Hirudinea; they dwell in fresh water and the sea and can be terrestrial. An oral sucker present anteriorly helps to attach to the host by releasing an anesthetic that prevents its recognition as a foreign body. Although many methods of leech removal have been proposed, its removal with forceps after instillation of local anesthetic remains a safe and effective method.

PURPOSE: To report keratouveitis arising from corneal penetration by a bristle worm seta (bristle). METHODS: We report on a 64-year-old woman presenting with uniocular pain, redness, reduced vision, discharge, and pustular rash of the hands after cleaning out her marine aquarium containing bristle worms and rubbing her eye. RESULTS: Slit-lamp biomicroscopy showed pseudomembranous conjunctivitis, corneal punctate erosions, stromal infiltrate, and edema, but no visible foreign body. The anterior chamber developed 3+ cells with hypopyon within 24 hours. Laboratory testing of corneal and hand samples was negative. In vivo confocal microscopy revealed a hair-like seta in the anterior corneal stroma, 25 to 105 µm wide, with surrounding inflammatory cells. Anterior chamber washout was performed. Topical prednisolone 0.5% was commenced, and corneal edema gradually resolved over 3 months. CONCLUSIONS: Bristle worms thrive as detritivores in marine aquarium sediment. Aquarium owners risk touching their setae during tank cleaning. Ophthalmia nodosa describes ocular reaction to caterpillar, vegetable, and spider hairs: features include posterior migration of hairs, granulomatous inflammation, and uncertain prognosis. Eye specialists should be alerted to the possibility of bristle worm-induced ophthalmia nodosa. Confocal microscopy may be useful in identifying microscopic setae.

PURPOSE: To describe the clinical presentation of migratory nematodes and to outline a simple strategy to ensure capture. METHODS: Retrospective case series. RESULTS: Two consecutive patients with suspected migratory nematodes were treated promptly by strategic placement of a pharmacological barrier in the forniceal conjunctiva using 1% lidocaine with epinephrine to block the routes of retreat and to immobilize the worms for controlled retrieval. Two live nematode worms, one subcutaneous dirofilaria and one subconjunctival Loa loa, were successfully removed. CONCLUSIONS: A sense of urgency is conveyed to isolate the migratory worm while it is still visible and residing in a location for easy surgical removal. The retreat of the worm to the deeper, inaccessible orbit is prevented by strategic placement of a perimeter of anesthetic.

PURPOSE: to present the case of a 4-year-old girl with leech infestation of the ocular surface. DESIGN: observational case report. RESULTS: a 4-year-old girl presented with a two-day history of bleeding from the left eye. Examination under anesthesia revealed a leech adhering to the cornea and bulbar conjunctiva. Irrigation with normal saline released the leech from the conjunctiva. Detaching from the cornea was successful after injection of suxamethonium 50 mg/ml into the worm. CONCLUSIONS: The possibility of leech infestation need to be considered in the differential diagnosis of open-globe injury with prolapse of uveal tissue. The use of a muscle relaxant for leech removal was not previously documented.

PURPOSE: We report a case of ocular worm treated surgically and confirmed by microbiological identification. METHODS: A 33-year-old Swiss woman presented to the ophthalmic unit, complaining of pain and foreign body sensation in the left eye. Slit-lamp examination disclosed a subconjunctival amber -colored cord in the conjunctival fornix. Presentation, clinical and histopathologic evaluation, and treatment are described. RESULTS: At the time of surgery, an alive and still intact worm was extracted through conjunctival incision. Histopathology confirmed the presence of filariasis. CONCLUSIONS: As the flow of immigrants from endemic areas of Europe increases, ocular manifestation of loiasis is becoming more frequent and ophthalmologists need to be aware of this diagnosis.

A 37 year old male was referred to our centre for management of episcleritis with peripheral keratitis in the right eye. He had a history of ocular discomfort in the right eye of 1 week duration. Slitlamp examination revealed marginal keratitis between 12'o clock to 2'o clock positions in the right eye. Lid eversion revealed an insect wing on the tarsal conjunctiva along with an adjacent conjunctival granuloma. The area of the marginal keratitis corresponded to the area of the foreign body and the conjunctival granuloma. The probable mechanism of the development of marginal keratitis and the conjunctiva granuloma is speculated in this case report.

PURPOSE: To describe a patient with manifestations of ocular leech infestation. METHOD: Case report. RESULTS: The ocular foreign body was identified as a leech, Limnatis nilotica, by parasitologic examination. The leech was extracted, and the patient began using topical antibiotic and cycloplegic agents. By the third day after extraction, the patient had no obvious symptoms or signs, except for a limited subconjunctival hemorrhage, and no epithelial defect on the cornea was observed. CONCLUSIONS: Ocular leech infestation should be considered in patients with a history of swimming in streams and lakes. Attention should also be given to ocular leech infestation in the differential diagnosis of ocular trauma with iris prolapse.

A cat had sudden onset of unilateral corneal edema, fibrin in the anterior chamber, uveal inflammation, and retinal dysfunction. A dead dipteran fly larva was removed surgically from the anterior chamber and was identified as an early instar of a Cuterebra sp.

A 16-year-old White girl presented with a foreign-body sensation in her right eye. Seven Oestrus ovis maggots were removed with the aid of a cotton wool-tipped probe. The subsequent history has been quite uneventful. This appears to be the fifth reported case of ophthalmomyiasis externa in southern Africa.
