Glaucoma update--what physicians and the public need to know.

With the aging population in Singapore, glaucoma will be more prevalent. The majority of glaucomas are silent and typically present late with advanced damage. A large proportion of glaucomas remain undetected. Screening for glaucoma is the only way to detect glaucoma early and high-risk groups should be screened. Early detection is important in preventing blindness as treatment is more difficult and less effective in the advanced stages of glaucoma. Greater awareness amongst physicians and the public is vital in the prevention of glaucoma blindness.

Glaucoma pattern amongst the elderly Chinese in Singapore.

Glaucoma is a major blinding condition and is more prevalent amongst the elderly. A population study of 479 elderly Chinese aged 60 years and older, and residing in Singapore was carried out to determine the prevalence of glaucoma. The overall glaucoma prevalence was 4.8% with normal tension glaucoma (61%) and primary angle closure glaucoma (26%) being the most prevalent forms of glaucoma. All cases were silent in presentation with 97% of cases previously undiagnosed. With the greying population in Singapore, the issue of screening the elderly for glaucoma should be considered.

Iris varix.

Varix of the iris as a solitary primary lesion is rare. We report a 31-year-old Indian man with an iris varix who developed recurrent haemorrhages into the anterior chamber which led to secondary glaucoma. An iridectomy was performed and the diagnosis was confirmed histologically. There has been no recurrence of the lesion 3 years after surgery.
