Study: Factors influencing the outcome of goniotomy and trab
Researchers aimed to study the prognostic factors influencing intraocular pressure (IOP) reduction and success rates of paediatric goniotomy and trabeculotomy.

Data from patients aged less than 12 years who underwent goniotomy or trabeculotomy for primary congenital glaucoma were reviewed. The analysis included 452 eyes of which 120 eyes of patients with a median age (IQR) of 6 months underwent goniotomy, and 332 eyes of patients with a median age of 5.2 months underwent trabeculotomy.

--In the goniotomy group, the median IOP reduction was 19.4% and was positively correlated to a high initial IOP while in the trabeculotomy group, it was 36.8% and mostly influenced by preoperative IOP, corneal clarity, gender and consanguinity.

--The failure rate in the goniotomy group was 56% and was influenced by the preoperative cup-to-disc ratio, while in the trabeculotomy group it was 30% and strongly correlated to positive consanguinity, higher preoperative IOP, female gender and younger age at surgery.

Finally, several criteria can help determine the optimal surgical intervention in paediatric glaucoma by predicting the success of angle surgery. In primary congenital glaucoma, trabeculotomy appears to be preferable than goniotomy.
