Objective: To report the 5‐year progression to primary angle closure glaucoma (PACG) in a
population‐based cohort of primary angle closure (PAC) subjects. Methods: A total of 37
patients diagnosed as PAC during a population‐based study in 1995 were invited for re‐
examination in 2000. Patients underwent a complete ophthalmic examination including
ocular biometry. Progression to PACG was based on optic disc damage and field defects on
automated perimetry. Results: In all, 28 of 32 PAC subjects who could be contacted …

Aim: To report progression of primary angle closure suspects (PACS) to primary angle
closure (PAC) at the 5 year follow up of a population based sample. Methods: 82 of 118
PACS who could be contacted and 110 randomly selected normals from a population based
survey in 1995 were invited for a follow up examination in 2000. Progression to PAC was
based on the development of raised IOP or synechiae in a PACS. Results: 50 of the 82
PACS contacted were examined. 11 (22%; 95% CI 9.8 to 34.2) developed PAC (seven …
