Abstract

Purpose: To study the changing indications for penetrating keratoplasty in Singapore and compare local indications with developed countries with established corneal graft programs. Methods: A descriptive study of all penetrating keratoplasty cases performed in the Singapore National Eye Center over a 5 year period, from 1 January 1991 to 31 December 1995 using records of the Singapore Eye Bank registry. Results: A total of 327 penetrating keratoplasties were performed. Bullous keratopathy was the indication in more than a quarter of all cases (26.3%). Aphakic bullous keratopathy (11.6%) and pseudophakic bullous keratopathy (11.3%) accounted for the majority of the bullous keratopathy cases. The other leading indications were: regrafts (11.9%), corneal dystrophies (10.4%), traumatic scarring (10.1%) and keratoconus (9.8%). A higher proportion of aphakic and pseudophakic bullous keratopathy as well as regrafts was noted in this series, compared to a previous report on corneal transplantation in the 1980s. A rising indication rate of pseudophakic bullous keratopathy, in conjunction with a declining indication rate of herpetic keratitis was observed over the 5 year study period. Conclusions: The indications for penetrating keratoplasty in Singapore appear to follow the trend seen in developed Western countries over the past few decades. [ABSTRACT FROM AUTHOR]
