The first case was documented by Gangadharam et al in 1978 and since then, a total of 49 cases were reported in the literature. One alarming fact is that more than 50% of cases were found in the Chinese population and mostly reported in recent years. The key to successful management of M. chelonei keratitis is early diagnosis by high index of suspicion. In order to alert ophthalmologists of this condition, we report a typical case of M. chelonei keratitis and review the literature of all the reported cases with special reference to its risk factors, treatments and outcome.Methods: The cases reported in the literature and a case of our own were reviewed and analyzed.Results: Our case was a 42-year-old gentleman who developed M. chlonei keratitis following pterygium surgery. He had typical clinical features of irregular infiltrates with radiating展开更多

Corneo-scleral graft is used in this study as an alternative material for its desirable properties of being transparent, higher in tensile strength, cheap and more readily available. Methods: Eighteen consecutive cases were implanted with the Ahmed glaucoma valve im-plant. The limbal portion of the silicone tube was covered by a comeo-scleral graft obtained from the corneo-scleral rim left over following corneal transplant operation. The effectiveness in protecting the tube from erosion or migration, the transparency of the patch graft and complications encountered after surgery were assessed.Results: At a mean follow-up of 6 months, all tubes were well protected and no complications related to the patch graft were encountered during intra and postoperative period. All comeo-scleral grafts remained transparent and展开更多
