| Summary: | Background: Early surgical intervention is required for the primary congenital glaucoma (PCG). There are currently few reports on the surgical outcomes in infants with PCG. This study aimed to evaluate the efficacy and safety of trabeculotomy and the postoperative visual outcomes in Chinese newborns with PCG within 4 weeks of birth.
Methods: A total of 21 eyes of 12 patients with PCG who underwent primary trabeculotomy within 4 weeks of birth were retrospectively studied. Preoperative and postoperative intraocular pressure (IOP), corneal clarity and diameter, axial length and optic disc cupping, visual acuity and postoperative refractive error, success rates, and complications were evaluated. Kaplan-Meier survival analysis was applied to evaluate the success rates.
Results: The mean follow-up time was 46.9 ± 34.4 months (range: 12–122 months). The postoperative IOP was significantly lower than the preoperative IOP at all of the follow-up visits (P < 0.001). The complete success rates for all eyes at 1, 2, 3, and 5 years postoperatively were 90.5%, 85.7%, 85.7%, and 85.7%, respectively. The IOPs of the three patients who needed antiglaucomatous medications postoperatively were also well controlled. At the last visit, the cornea became clear, and the cup-to-disc ratio decreased significantly (P = 0.01) although the horizontal corneal diameter did not change significantly (P = 0.11). Visual acuities were able to be recorded in eight eyes at the last visit, among which six eyes had a best-corrected visual acuity of 20/40 or better. There were no severe intraoperative or postoperative complications.
Conclusions: Trabeculotomy proves to be a safe and effective treatment in reducing IOP in this group of Chinese newborns with PCG. The outcomes of vision function were satisfactory in most of the patients.
