Purpose:
This study aims to describe the technique, feasibility, efficacy, and safety of 360° trabeculotomy ab externo with double access for the treatment of congenital glaucoma.
Methods:
This paper provides a detailed description of the 360° trabeculotomy ab externo with double access used to treat pediatric glaucoma. The postoperative outcomes of six eyes from six patients who underwent this procedure for primary and secondary congenital glaucoma are also reported.
Results:
Six eyes from six patients were included in this study. The median age of the patients at the time of surgery was 1.25 yr (range: 0.27-5.41 yr). The mean preoperative intraocular pressure was 25 ± 5.87 mmHg (range: 18-35 mmHg). At baseline, the mean number of hypotensive eye drop medications used was 2 ± 0.63. Postoperatively, the mean intraocular pressure decreased to 10 ± 2.20 mmHg (range: 9-14 mmHg), and none of the patients required hypotensive eye drops. The most common postoperative complication was hyphema, observed in one case on the first postoperative day; however, it resolved within 7 days.
Conclusions:
The 360° trabeculotomy ab externo with double access is a valuable addition to the surgical options for pediatric glaucoma. This technique facilitates a complete 360° ab externo opening of the trabecular meshwork while enhancing surgical safety.
