The research aimed to improve surgical techniques and long-term outcomes by utilizing this advanced imaging technology to illuminate the structural abnormalities of the anterior segment in eyes with primary congenital glaucoma.

Primary congenital glaucoma (PCG) is a rare disease, but it is responsible for 2.5%-15% of all documented cases of pediatric blindness.

The main target of the treatment of pediatric glaucoma is to control the IOP surgically. However, medical treatment could be instituted as a temporary and/or adjunctive option to maximize Intraocular pressure (IOP) control. Initial goniotomy or trabeculotomy have been detected to have high success rates. Trabeculotomy has a comparable long-term success rate in most patients of PCG. The success rate of trabeculotomy is lower in advanced or late-presenting patients.

Inclusion Criteria:

• Age from 1 to 72 weeks.
• Both sexes.
• Infants with primary congenital glaucoma.

Exclusion Criteria:

• Eyes in which the angle could not be visualized by the handheld anterior segment optical coherence tomography (HH AS-OCT).
• Eyes with previous intraocular surgery.
