Glaucoma Drainage Surgery In A Scarred Eye

Michigan rates for HCPCS 66172

Creates a new drainage route through the white of the eye so fluid can escape and the pressure inside falls. This version is for an eye already scarred by earlier surgery or injury, where healing tends to seal the new channel shut, so extra measures are taken to keep it open. Pressure is checked frequently in the weeks afterwards.
