Glaucoma is a chronic, progressive deterioration of the optic nerve fibers at the back of the eye that carry visual messages from the retina to the brain. Glaucoma is usually caused by or worsened by intraocular pressure inside the eye that is too high for the continued health of the nerve.
Most types of glaucoma are typically painless and produce no symptoms until noticeable vision loss occurs. With acute angle-closure glaucoma, symptoms like blurry vision, intense eye pain, nausea and vomiting may be experienced.
Glaucoma treatment can involve surgery, laser treatment or medication, depending on the severity. First line glaucoma treatment involves using eye drops with medication aimed at lowering intraocular pressure.
The only proven glaucoma treatment is lowering eye pressure in order to prevent or to slow down the damage to the optic nerve. It’s commonly done through glaucoma surgery that includes delicate and microscopic equipment. There are also newer procedures for glaucoma treatment called minimally invasive glaucoma surgery that have a higher safety profile.
Each type of glaucoma surgery has its unique advantages and disadvantages. These surgeries have a very high success rate in slowing down the progression of glaucoma. The benefits typically outweigh the rare risks associated with this surgery.
Vision Loss - Glaucoma surgery may temporarily disrupt your vision soon after the operation.
Bleeding - Uncommon or rare complications include bleeding inside the eye, infection, and fluid pockets behind the retina due to very low eye pressures and should be treated urgently.
Infection - On very rare occasions, despite antibiotics, infection inside the eye may occur, which can be very serious and may threaten vision for weeks, months, or even years after the surgery.
Low Eye Pressure - Sometimes, the surgery can lead to temporary eye pressures that are too low, also called hypotony. This is more common soon after the surgery causing a shadow in your peripheral or side vision.
Scarring- Some surgeries may fail over time due to the natural scarring tendencies of the eye, resulting in higher eye pressures.
Cataract- Cataract formation most likely will be accelerated by glaucoma surgery, but luckily cataracts are fairly easy to fix surgically.
It is also important to recognize that the vast majority of glaucoma surgeries are a successful glaucoma treatment slowing its progression and achieving the intended eye pressure. Post-surgery care for a glaucoma patient is essential as it may take a while before the patient can resume the activities of daily living.
