To elucidate long-term surgical outcome of trabeculotomy ab externo in the treatment of developmental glaucoma.
Included in this retrospective study are 116 eyes of 71 patients with developmental glaucoma. We classified patients into three groups based on their age: congenital (33 eyes), existing before age 2 months; infantile (31 eyes), occurring from ages 2 months to 2 years; and juvenile (52 eyes), age 2 years or older.
A life-table analysis showed that the total success probabilities at 5 and 10 years with one or more trabeculotomy ab externo operations were, respectively, 92.5%±2.7% and 76.5%±6.2%. The success probability of patients with congenital glaucoma (60.3%±15.9%) was significantly lower than it was for those with infantile (96.3%±3.6%) or juvenile (76.4%±7.5) glaucoma (P<.01 for both).
Surgical results of trabeculotomy ab externo remain effective for a long time. Congenital glaucoma has the worst prognosis, and infantile glaucoma has a better prognosis than does juvenile glaucoma.
