What is Primary Open-Angle Glaucoma (POAG)? - Glaucoma Glossary

Primary Open-Angle Glaucoma is the most common form of glaucoma, characterized by progressive optic nerve damage and visual field loss with a physically open anterior chamber angle.

What it means for the patient

This is often called the "sneak thief of sight" because it happens very slowly. The drainage angle of your eye looks open and normal to a doctor, but the microscopic fluid filter is chronically clogged, slowly raising eye pressure.

Clinical significance

POAG accounts for nearly 90% of all glaucoma cases. It requires lifelong trajectory monitoring to ensure the rate of retinal ganglion cell loss does not outpace the patient's life expectancy.

How it is tracked

Tracked via longitudinal charting of Visual Field Index (VFI), OCT RNFL thickness, and routine applanation tonometry on the Glaucoma One analytics platform.
