Purpose: To evaluate frequency of surgery and post-treatment outcomes in glaucoma following cataract surgery (GFCS).
Methods: The medical records of patients with GFCS were reviewed retrospectively. Lensectomy and glaucoma surgery details and final examination findings were collected. Inclusion criteria included history of lensectomy at <1 year of age, diagnosis of glaucoma, and at least 1 year of follow-up.
Results: Of 169 eyes of 127 GFCS patients (66 male, 58 bilateral cases), 88 eyes (52%) of 73 (57%) patients underwent glaucoma surgery (median, 3.5 years of age at first glaucoma surgery; median of two glaucoma surgeries). At final follow-up (mean, 13.6 ± 7.0 years), eyes requiring glaucoma surgery had worse visual acuity (P = 0.01) and greater cup:disk ratio (P < 0.01). GFCS patients with history of bilateral congenital cataracts had better visual acuity in affected eyes than those with history of unilateral congenital cataract (P < 0.01). Angle surgery (n = 56), Baerveldt devices (n = 38), Ahmed valves (n = 19), and cycloablation (n = 21) showed 1-year survival rates between 64% and 75%. Baerveldt implants showed the highest 5- and 10-year survival rates, at 65% and 43%, respectively.
Conclusions: More than 50% of eyes with GFCS in our study cohort required at least one glaucoma surgery. Glaucoma surgery and history of unilateral cataract were associated with worse visual acuity outcomes.
