Abstract

Exfoliation syndrome(XFS)has rarely been reported in Korea even though its worldwide distribution. The purpose of this study is to report clinical manifestations of XFS in Korea and to determine its relationship to the development of glaucoma in patients with XFS. We retrospectively reviewed the medical records of 31 patients with XFS presenting over a 6-year period at Yeungnam university hospital. Patients were considered to have XFS if characteristic fibrillar exfoliative materials were visualized on the anterior lens capsule. We investigated clinical features such as gender, age, combined systemic disease, laterality, presence of cataract or glaucoma, methods of treatment and complications. We could identify 24 males and 7 females with XFS. All the cases were aged 60 years or more except one case, with the peak in the eighth decade(mean 71.5, range from 37 to 92 years). In 11 patients(35%), XFS was bilateral. Cataract was associated in 28 eyes(67%)out of the total 42 eyes and cataract extractions were performed in 8 eyes. Glaucoma developed in 17(55%)out of the total 31 patients, with the predilection toward the case with bilateral involvement(73%)of XFS, and 44%of glaucomatous eyes required trabeculectomy. The clinical features of XFS in Korea were similar to previous reports from other parts of the world, but interestingly male predominance was a unique finding in this study. Our study suggests that XFS occurs not uncommonly among the Korean population.
