Iridotomy to slow progression of angle-closure glaucoma

The primary objective is to assess the role of iridotomy—compared with observation—in the prevention of visual field loss for individuals who have primary angle closure or primary angle-closure glaucoma in at least one eye. We will also examine the role of iridotomy in the prevention of elevated intraocular pressure (IOP) in individuals with narrow angles (primary angle-closure suspect) in at least one eye.

This is a protocol.
