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.
