Abstract in English, FrenchPurpose: To report the outcome of combined trabeculotomy-trabeculectomy among children with primary congenital glaucoma at a child eye health tertiary facility in southwest Nigeria.
Methods: A retrospective review of children who underwent combined trabeculotomy-trabeculectomy (CTT) surgery on account of primary congenital glaucoma between 2016 and 2020 at the University College Hospital, Ibadan, Nigeria. All surgeries were performed by paediatric ophthalmologists. The main outcome measures were postoperative intraocular pressure, corneal clarity, and complications.
Results: A total of 21 eyes of 13 patients were included. Ten (76.9%) of the patients were males and 8 (61.5%) had bilateral disease. The mean age at presentation was 4.8 (± 3.6) months, while the mean age at surgery was 8.1 (± 5.9) months. The average waiting time between noticing symptoms and presenting to the clinic was 3.2 (±4.9) months. The mean horizontal corneal diameter was 13.2 (± 1.4) mm, while the mean pre-operative intraocular pressure (IOP) was 25.7 (± 8.6) mmHg. The surgical success (IOP<21 mmHg) rates at 3, 6, and 12 months were 86.7%, 64.3%, and 92.9% respectively. The Kaplan-Meier estimates of the probability that IOP remained below 21 mmHg up till 3, 6, and 12 months were 74%, 53%, and 53% respectively. Postoperatively, 85.7% of the eyes had complete resolution of corneal oedema. One eye had an intraoperative complication of vitreous loss. The post-operative clinic follow-up rate reduced to 52.4% by 1 year.
Conclusion: Combined trabeculotomy-trabeculectomy is a relatively safe procedure that is associated with favorable success in Nigerian children with primary congenital glaucoma.
