.
● Peripheral anterior synechiae may occur when the posterior
portion of the trabecular meshwork or other structures
posterior to the meshwork are treated. These are best
avoided by meticulous delivery of a well-focused laser beam.
Transient corneal epithelial burns have reportedly resolved within 1 week
without scarring. Endothelial burns are rarely encountered when careful
focusing is employed.
A “snuff out” of the central visual acuity has been reported as a
complication of an intraocular pressure spike. Patients with advanced field
loss should be carefully treated and monitored. Progressive field loss
following laser trabeculoplasty is possible, even in the presence of
seemingly adequately controlled intraocular pressure

.
Rarely, severe iritis may occur, related to either an unusual patient
response or improper spot location.
