Laser trabeculoplasty in open angle glaucoma.

Laser trabeculoplasty was performed in 72 patients (81 eyes) with open angle glaucoma. A positive correlation between pre-laser pressure level and pressure reduction was found. In 23 eyes with POAG and an average pre-treatment pressure of 26.4 mmHg, post-laser IOP 6 months later was 21.6 (18% reduction) and 1 year later 21.8 mmHg (17% reduction). In 24 eyes with CG and an average pre-treatment pressure of 32.9 mmHg, post-laser IOP 6 months later was 23.8 mmHg (28% reduction) and 1 year later 22.8 mmHg (31% reduction). All eyes needed additional medical therapy for glaucoma control, and 8 eyes had to be operated. Three eyes had complications. One eye had a pressure rise on the 2nd post-operative day, and two eyes had a haemorrhage from the chamber angle.
