OBJECTIVE: To elucidate long-term surgical outcome of trabeculotomy ab
externo in the treatment of developmental glaucoma. PATIENTS: 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. RESULTS: 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).
CONCLUSIONS: 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.
