Factors predisposing to central corneal ulceration in a developing population.

Over a 1-year period all patients presenting to St John's Eye Hospital with corneal ulceration were studied. The local and general factors predisposing to central (primarily infective) corneal ulceration are discussed. Episodes of corneal trauma and climatic droplet keratopathy were the major local factors and these occurred against the background of a generally poor nutritional status.
