Glaucoma Shunt Surgery

glaucoma shunt surgery

Glaucoma shunt surgery is an operation that places a small device in the eye to help drain extra fluid and lower pressure. High pressure inside the eye can damage the optic nerve and lead to vision loss, and this surgery is used when medicines or less invasive treatments are not enough. The device usually has a tiny tube connected to a flat plate that sits under the outer covering of the eye, creating a new path for fluid to leave. The surgeon places the tube inside the front part of the eye and secures the plate on the white part of the eye so fluid can collect and be absorbed. The procedure is often done with local or general anesthesia and can take an hour or more depending on the case. After surgery, patients typically use antibiotic and anti-inflammatory eye drops and have regular follow-up visits to check healing and pressure. Like any surgery, it carries risks such as infection, bleeding, low eye pressure, tube exposure, or changes in vision, but many people benefit with better pressure control. Recovery time varies but most people notice gradual improvement over weeks to months while the eye adjusts. Successful pressure control from the shunt can slow or prevent further optic nerve damage and preserve remaining vision. Choosing this surgery involves weighing risks and benefits with an eye specialist to decide if it offers the best chance to protect sight.
