Efficacy and Safety of Gonioscopy-Assisted Transluminal Trabeculotomy for Primary Congenital Glaucoma
(Lippincott Williams & Wilkins, 2023) Aktas, Zeynep; Ozmen, Mehmet C.; Ozdemir Zeydanli, Ece; Oral, Merve; Eskalen, Oguzcan
Precis:Gonioscopy-assisted transluminal trabeculotomy (GATT) provided effective intraocular pressure (IOP) control in primary congenital glaucoma (PCG). Also, approximately two third of patients did not need antiglaucoma medication at an average follow-up of 1 year after surgery. Purpose:The purpose of this study was to assess the safety and efficacy of GATT surgery in eyes with PCG. Materials and Methods:This study is a retrospective review of patients who underwent GATT surgery for PCG. Outcome measures were changes in IOP and number of medications at all time points (1, 3, 6, 9, 12, 18, 24, and 36 mo after surgery), and success rates. Success was defined as IOP<21 mm Hg with at least a 30% reduction from the baseline, complete if without medications, or qualified if with or without medications. Cumulative success probabilities were analyzed using the Kaplan-Meier survival analyses. Results:Twenty-two eyes of 14 patients diagnosed with PCG were enrolled in this study. The mean IOP reduction was 13.1 mm Hg (57.7%) with a mean decrease of 2 glaucoma medications at the final follow-up. All mean IOP readings during postoperative follow-up were significantly lower than baseline (P<0.05 for all). Cumulative probability of qualified success was 95.5% and the cumulative probability of complete success was 66.7%. Conclusion:GATT was safe and successfully lowered IOP in patients with PCG with the advantage of avoiding conjunctival and scleral incisions.

Risk Factors for Trabeculotomy Failure in Primary Congenital Glaucoma
(Lippincott Williams & Wilkins, 2022) Aktas, Zeynep; Ucgul, Ahmet Y.; Boluk, Ceyda E.; Atalay, Hatice T.
Precis:This study demonstrates that a baseline corneal diameter >12.25, initial age <4 months at diagnosis, higher baseline IOP than 24 mm Hg, bilaterality, or inability to perform circumferential trabeculotomy, increases the risk of surgical failure of trabeculotomy in patients with primary congenital glaucoma (PCG). Purpose:The aim of this study was to identify clinical predictive factors for surgical failure and to evaluate potential prognostic factors affecting surgical success in patients with PCG who underwent trabeculotomy. Patients and Methods:The medical charts of 123 eyes of 75 patients who underwent trabeculotomy surgery for the treatment of PCG were retrospectively reviewed. At baseline and each visit, intraocular pressure (IOP), corneal diameter, cup to disc ratio, axial length, number of medications, and need for further glaucoma surgery were noted. Surgical success was defined as an IOP <= 18 mm Hg and 20% IOP reduction from baseline with (qualified) or without (complete) medication and without any further IOP-lowering surgery. Results:The mean age at surgery was 4.2 +/- 6.6 months and the mean follow-up time was 60.0 +/- 37.6 months. The receiver operating characteristic curve showed 4 following best cutoff values to predict surgical failure: the first for age at surgery was 4.5 months; the second baseline IOP was 24.0 mm Hg; the third for baseline cup to disc ratio was 0.4; and the fourth for baseline corneal diameter was 12.25 mm. Multivariate logistic regression analysis revealed that baseline IOP more than 24 mm Hg increased the risk of surgical failure by 2 times, baseline mean corneal diameter >12.25 mm did by 4.2 times, younger age than 4 months did by 2.5 times, bilaterality did by 1.5 times. Conclusions:A higher baseline IOP, younger age, larger corneal diameter, and bilaterality were identified as risk factors for trabeculotomy failure in congenital glaucoma. The presence of one or more of these should be considered in the decision-making process when considering surgical options to manage glaucoma in these patients.
