The prevalence of pseudoexfoliation syndrome in older Chinese patients is low, well under 1%, according to a study.
A.L. Young, MD, and colleagues at the Price of Wales Hospital in Hong Kong recruited 500 patients aged 60 years or more with a presumed diagnosis of cataract into a prospective study to determine the incidence of pseudoexfoliation syndrome.
The patients ranged in age from 60 to 91 years old; 40% suffered from hypertension and 24% were known to have diabetes. Two cases (0.4%) were found to have pseudoexfoliation syndrome. Nuclear sclerosis was the single most common type of lens opacity.
The study is published in the February issue of British Journal of Ophthalmology.
