[Factors influencing the effectiveness of argon laser trabeculoplasty]

The effectiveness of argon laser trabeculoplasty in managing the primary open-angle glaucoma was observed in 103 patients (202 eyes) in period of 3 years. The authors are confirming its good effects, the maximum of it in three months after the trabeculoplasty. The best response was achieved in patients with the preoperative intraocular pressure lower than 25 mmHg and in the age group above 60 years. To obtain the good results after the operation in 87.12% of patients the local medical treatment was necessary, although in 51.98% the medication was reduced. The effectiveness of operation was decreasing with time, in 2 years was just 56.93% and in three years 23.27%. The significant improvement of outflow facility was observed in 85% of cases by electrotonography.
