[Long-term effect of extra-trabeculectomy in treatment of congenital glaucoma].

OBJECTIVE

To assess the long-term effect of extra-trabeculectomy in treatment of congenital glaucoma.

METHODS

29 patients (47 eyes) with congenital glaucoma having undergone extra-trabeculectomy were followed up for over 5 years.

RESULTS

Success rates after single surgery were 70.2% at 6 months, 63.8% at 12 months, 57.5% at 18 months and 55.3% at 24 months. Re-elevation of intraocular pressure (IOP) all happened within 2 years after surgery. 14 eyes underwent second trabeculectomy, and 7 eyes (50.0%) were successful the total success rate was 70.2%. The naked visual acuity of 12 eyes (36.0%) among successful eyes was >or= 0.5. All the diseased eyes were myopic (-0.50 to -25.00 D).

CONCLUSION

Follow-up of trabeculectomy should be emphasized within 2 years after surgery. Ametropic and anisometropic amblyopia should be corrected promptly after surgery.
