Abstract
Oculomycosis is a severe problem in most developing countries. Specific antifungal agents are often unavailable, and are expensive. The use of antiseptic agents was therefore explored. Fungal isolates from patients in India and Ghana were tested against chlorhexidine, povidone iodine, propamidine, and polyhexamethylenebiguanide, and compared with econazole by placing the drugs in wells made in Sabouraud's agar plates seeded with the test organism. Fungal sensitivity testing is a contentious area but this method is simple and cheap. Chlorhexidine showed a good dose related response, povidone iodine showed a good response at all concentrations and econazole was the most effective in vitro. A small pilot study was conducted in India to assess clinical efficacy for fungal corneal ulcers. Both chlorhexidine and econazole proved effective but povidone iodine was ineffective. We suggest that chlorhexidine may be a useful first line agent for fungal keratitis when other antifungals are not available.
