Primary infantile glaucoma (congenital glaucoma)

Area of Science:

• Ophthalmology
• Genetics
• Pediatric Medicine

Background:

• Primary infantile glaucoma (congenital glaucoma/trabeculodysgenesis) is an inherited anomaly affecting the anterior chamber angle.
• It obstructs aqueous outflow, leading to elevated intraocular pressure and optic nerve damage.
• The exact pathogenesis remains debated, with initial theories on endothelial membranes not consistently supported by ultrastructural evidence.

Purpose of the Study:

• To review the understanding and management of primary infantile glaucoma.
• To highlight the role of surgical versus medical treatment.
• To discuss prognostic factors and monitoring parameters in neonates.

Main Methods:

• Literature review and synthesis of existing research on primary infantile glaucoma.
• Analysis of treatment outcomes for surgical interventions like goniotomy and trabeculotomy ab externo.
• Evaluation of prognostic indicators and monitoring techniques.

Main Results:

• Surgical treatment (goniotomy, trabeculotomy ab externo) is the primary definitive therapy for primary infantile glaucoma.
• Both surgical methods yield similar good results in most patients.
• Prognosis is influenced by presentation time, surgical intervention, optic nerve damage, corneal changes, refractive error, and amblyopia.

Conclusions:

• Medical therapy plays a supportive role, with surgery being essential.
• Early surgical intervention is crucial for favorable outcomes.
• Corneal diameter and intraocular pressure are vital for monitoring, though not exclusively relied upon for assessing treatment success.
