Subscleral Trabeculectomy With Inverted T-Shaped Deep Sclerectomy for Primary Congenital Glaucoma
Sponsor: Benha University
Summary
Primary congenital glaucoma (PCG) is a vision-threatening disorder of childhood characterized by elevated intraocular pressure (IOP) resulting from developmental abnormalities of the anterior chamber angle. Early surgical intervention is the standard treatment to preserve visual function and prevent progressive optic nerve damage. This retrospective interventional case series evaluated the safety and efficacy of subscleral trabeculectomy combined with an inverted T-shaped deep sclerectomy (El-Habbak modification) in children with PCG. Medical records of patients who underwent surgery between January 2022 and June 2025 at Benha University Hospital were reviewed. The primary outcome was reduction in intraocular pressure. Secondary outcomes included surgical success rates, reduction in antiglaucoma medication use, changes in corneal clarity and optic nerve status, postoperative complications, and the need for additional glaucoma surgery following a minimum follow-up of 12 months.

Interventions
Subscleral Trabeculectomy Combined With Inverted T-Shaped Deep Sclerectomy
Subscleral trabeculectomy was performed beneath a superficial scleral flap, followed by creation of an inverted T-shaped deep sclerectomy (El-Habbak modification). The modification consisted of a vertical deep scleral channel extending toward the limbus and a posterior horizontal extension to create an enlarged intrascleral filtration reservoir. Peripheral iridectomy was then performed, and the scleral flap and conjunctiva were closed in the standard fashion. The procedure was intended to enhance aqueous humor outflow while maintaining controlled filtration and reducing postoperative fibrosis.
