Abstract

Acute and permanent loss of vision has resulted from foveal photocoagulation during argon laser iridotomy. This complication can occur when the laser beam passes through the iridotomy nearly parallel to the visual axis. This is most likely to happen during enlargement of the iridotomy. A retinal burn of the macular region through a peripheral iridotomy was produced experimentally, and the mechanism of this complication is explained.

    Citation Excerpt :

    When the iridotomy is done correctly, both intraoperative and long-term complications are very rare. There are reports in the literature of isolated cases with complications, including some that are serious: retinal detachment, cataract, lens luxation, and rupture of Descemet's membrane (Mastropasqua et al., 1984; Zadok and Chayet, 1999; Liu et al., 2002). The most common complications are less severe.
