Summary

This study looks at children with a rare, severe eye disease called primary congenital glaucoma. It compares three different amounts of a surgery called goniotomy (120°, 240°, or 360°) to see which works best and is safest. The goal is to lower eye pressure and protect vision, but children may still need eye drops or more treatment later.
