Corneal blindness in Singapore and its prevention

The pattern of corneal disorders in Singapore is different from that seen in the western countries, and in the developing countries. Dendritic corneal ulceration, keratoconus and corneal dystrophy are relatively uncommon. Bullous Keratopathy, however, is on the increase, due mainly to the increasing number of cataract operations done and to the use of intraocular implants. Other major corneal disorders in Singapore are Exposure Keratitis and Neurotrophic Keratitis. The management of the various corneal disorders are discussed. Prevention is possible especially in those disorders due to iatrogenic factors. Constant vigilance and care are called for to prevent unnecessary surgical trauma and corneal blindness.
