Updates on the Surgical Management of Pediatric Glaucoma.

Childhood glaucoma is known to be one of the most challenging conditions to manage. Surgical management is more complicated than in adults because of differences in anatomy from adults along with variations in anatomy caused by congenital and developmental anomalies, wide-ranging pathogenetic mechanisms, a more aggressive healing response, and a less predictable postoperative course. Challenges in postoperative examination and management in less cooperative children and the longer life expectancies preempting the need for future surgeries and reinterventions are also contributing factors. Angle surgery is usually the first-line treatment in the surgical management of primary congenital glaucoma because it has a relatively good success rate with a low complication rate. After failed angle surgery or in cases of secondary pediatric glaucoma, options such as trabeculectomy, glaucoma drainage devices, or cyclodestructive procedures can be considered, depending on several factors such as the type of glaucoma, age of the patient, and the severity and prognosis of the disease. Various combinations of these techniques have also been studied, in particular combined trabeculotomy-trabeculectomy, which has been shown to be successful in patients with moderate-to-advanced disease. Newer nonpenetrating techniques, such as viscocanalostomy and deep sclerectomy, have been reported in some studies with variable results. Further studies are needed to evaluate these newer surgical techniques, including the use of modern minimally invasive glaucoma surgeries, in this special and diverse group of young patients.
