Navigating Primary Congenital Glaucoma (PCG): A Caregiver's Guide

At a Glance

Primary Congenital Glaucoma (PCG) is a rare eye condition in infants that requires immediate surgical intervention to protect long-term vision. The diagnostic gold standard is an Exam Under Anesthesia (EUA), and lifelong monitoring is essential to prevent complications like amblyopia.

A diagnosis of Primary Congenital Glaucoma (PCG) is a sudden detour in your parenting journey. It is a rare developmental condition affecting your infant’s eyes, and it requires specialized, immediate attention [1]. While the medical terminology, frequent appointments, and surgical plans may feel overwhelming, you do not have to navigate this alone.

This guide was built to help you understand your child’s condition, evaluate their care, and prepare for the long-term journey. It is designed to take you from a place of panic to a place of empowered advocacy.

We have broken down the most critical information into five key sections:

01

Understanding Your Infant's Diagnosis: Primary Congenital Glaucoma

Understand your infant's Primary Congenital Glaucoma (PCG) diagnosis. Learn about genetic causes, eye drainage issues, and why surgery is the primary treatment.

02

Identifying the Signs: More Than Just "Big Eyes"

Learn the early signs of Primary Congenital Glaucoma (PCG) in infants. Understand the classic triad, enlarged eyes, and when to see an eye specialist.

03

The Diagnostic Gold Standard: The Exam Under Anesthesia (EUA)

Learn what to expect during an Exam Under Anesthesia (EUA) for primary congenital glaucoma. Understand IOP, corneal measurements, and optic nerve cupping.

04

Repairing the Drain: Why Surgery is the Path Forward

Learn why surgery is the standard of care for primary congenital glaucoma (PCG). Understand infant procedures like goniotomy, trabeculotomy, and GATT options.

05

The Marathon of Care: Long-term Vision and Monitoring

Learn about long-term vision care for primary congenital glaucoma. Understand monitoring schedules, amblyopia treatment, and protecting your child's sight.

Take this one step at a time. Armed with the right information, you can help ensure your child receives the excellent, precise care they need to protect their vision.

Common questions in this guide

What is primary congenital glaucoma (PCG)?
Primary congenital glaucoma is a rare developmental eye condition affecting infants. Because it impacts the eye's drainage system and pressure, it requires immediate, specialized medical attention to prevent vision loss.
What are the early warning signs of congenital glaucoma in a baby?
Signs include unusually large eyes, excessive tearing, and light sensitivity, which are known as the classic triad. These symptoms are sometimes mistakenly diagnosed as a routine blocked tear duct, so evaluation by a specialist is crucial.
How do doctors formally diagnose PCG in infants?
The gold standard for diagnosing infant glaucoma is an Exam Under Anesthesia (EUA). This allows the surgical team to safely and accurately take measurements of the eye's pressure and physical structure while the baby is completely asleep.
Can primary congenital glaucoma be treated with just eye drops?
While eye drops may be used to help manage the condition temporarily, surgical intervention is the absolute standard of care. Surgery is necessary to physically repair the eye's drainage system and protect the child's long-term vision.
Where can parents find support for a child's PCG diagnosis?
It is highly recommended to ask your pediatric ophthalmologist or surgical team for specialized support groups. Connecting with other parents who have navigated infant glaucoma can provide essential emotional support and practical advice.
