[Prognosis in juvenile glaucoma after trabeculectomy].

PURPOSE

To evaluate the efficacy of trabeculectomy in the patients with juvenile glaucoma in the long-term follow-up.

MATERIAL AND METHODS

In 22 of 37 patients--41 trabeculectomies with basal iridectomy were performed. The age of children ranged from 6 to 18 years, mean 12.4 years. In one eye of 15-year-old boy we used Mitomycin C during reoperation. The follow-up period ranged from 2 to 14 years, mean 8 years. Patients were divided into 2 groups depending on the follow-up: I group (19 eyes) was observed 2-6 years, mean 5.1 years, II group (18 eyes) 7-14 years, mean 11.1 years. In the I group 57.9% and in the II group 61% of children were myopic.

RESULTS

Intraocular pressure lower or equal to 21 mmHg with no glaucoma medication was obtained in 79% of eyes in the I group and 66.7% of eyes in the II group. The difference was not statistically significant. In other eye local application of B-blockers and dorzolamid decreased intraocular pressure to values safe for the optic nerve, what was monitored by visual acuity and laser scanning tomography.

CONCLUSION

Prognosis of juvenile glaucoma patients treated with trabeculectomy is satisfactory but the effectiveness of this procedure decreases together with the elongation of the follow-up period.
