OBJECTIVES: To describe a rare case of bilateral stromal keratitis and demonstrate the effectiveness of penetrating keratoplasty in the management of toxocara keratitis. METHOD: This is a case report. RESULTS: A 53-year-old male farmer had a 10-month history of bilateral corneal opacity, photophobia, redness, foreign body sensation, and eye pain. The diagnosis was central microbial keratitis with the following etiologies considered: Epstein-Barr virus, herpes simplex, fungal, syphilis, tuberculosis (TB), myobacteria other than TB, and acanthamoeba. Despite treatment with topical steroids and antibiotics, both eyes worsened. Penetrating keratoplasty markedly improved the patient's visual acuity. Histopathology of the left corneal button revealed toxocara keratitis. CONCLUSION: Good history taking, complete systemic and ocular examinations, and a histopathology of the corneal tissues are vital to the diagnosis of toxocara keratitis. Penetrating keratoplasty was shown to be effective in its management. Emphasis is given on prevention to decrease the incidence of the disease.

This study is proposed as an alternative method of sterilization in developing countries Purpose: To determine the efficacy of using a commercially available convection broiler in sterilization of ophthalmic surgical instruments Methods: Surgical ophthalmic instruments were contaminated artificially with Staphylococcus epidermidis, Pseudomonas aeruginosa, and Aspergillus. The instruments were subjected to heat sterilization using the convection broiler at different temperature settings. After which, the instruments were cultured with appropriate media to determine contamination Results: 15 minutes heat sterilization at 260 degrees centigrade was enough to sterilize the contaminated ophthalmic surgical instruments Conclusion: Heat sterilization using a convection broiler provide a cheaper yet effective method of sterilization.
