Abstract
Aims
To determine the efficacy and safety of trabeculotomy in congenital glaucoma patients operated on within first 3 months of birth.
Methods
A total of 36 eyes of 24 patients with congenital glaucoma, who underwent primary trabeculotomy within first 3 months of birth were included. Preoperative and postoperative intraocular pressures (IOP), corneal clarity, diameter, axial length, success rates, and complications were evaluated in this study.
Results
The mean follow-up was 38.38
11.77 months (range 12–48 months). Mean IOP was 33.167.28 mmHg (range 23–50 mmHg) preoperatively. At the final follow-up visit, the mean IOP was 21.417.34 mmHg (range 8–38 mmHg). Pre-and postoperative IOP differences were statistically significant at all examination periods (P<0.001). A12-, 24-, and 36-month success rates were 92, 82, and 74%, respectively. Survival analysis regarding to gender, preoperative corneal diameter and consaguinity were not statistically significant. Only preoperative axial length was a statistically significant parameter (P=0.024) for success. Postoperatively normal corneal clarity was achieved in 29 eyes (80.5%). The main complications were shallow anterior chamber in one (4.2%) eye and detachment of Descement's membrane in two (8.4%) eyes.
Conclusions
Primary trabeculotomy is a safe and effective procedure for congenital glaucoma patients when operated within 3 months of birth. It has a favourable IOP control and a low rate of complications in three year period.
