Abstract

The introduction of a microsurgical technique in the trabeculotomy abexterno led to further improvement in the control of intraocular pressure of congenital glaucoma. We assessed the long-term efficacy of trabeculotomy and visual outcomes of congenital glaucoma patients who underwent trabeculotomy. The mean follow-up period was 5.5 years(ranging from 4.5 to 8.0 years). The operation was successful in 15 eyes after a single procedure; all the 4 failed eyes underwent the same operation again and the second operation was successful in all cases. Final success was 14 eyes. Average reduction of the intraocular pressure achieved by trabeculotomy was 13.6+/-9.0mmHg. The associated ocular disorder of congenital glaucoma included Haabs striae in 11 eyes(61.1%) and amblyopia in 3 eyes and astigmatism in 1 eye, optic atrophy in 1 eye, anisometropia in 1 case and strabismus 1 case. In long-term follow-up, the visual acuities were more than 0.4 in 12 eyes and less than 0.4 in 6 eyes. In conclusion, Amblyopia should be appropriately treated, as well as increased intraocular pressure in congenital glaucoma patients.
