This new opening allows the intraocular fluid to bypass the clogged drainage canals and flow out of this new, artificial drainage canal. When laser surgery does not successfully lower eye pressure, or the pressure begins to rise again, the doctor may recommend incisional surgery.
Occasionally, glaucoma surgery may have to be repeated especially if excessive scarring cannot be prevented or after long periods of time. Read more about incisional surgery ». Was this helpful? Yes No. Currently, all therapy for glaucoma is directed at lowering eye pressure, but the fundamental problem in glaucoma is the degeneration of the optic nerve fibers necessary for vision.

This is where a high-energy beam of light is carefully aimed at part of your eye to stop fluid building up inside it. Laser treatment is usually carried out while you're awake. Local anaesthetic drops are used to numb your eyes — you may just feel a brief twinge of pain or heat during the procedure.
Surgery may be recommended in rare cases where treatment with eyedrops or laser haven't been effective. The most common type of surgery for glaucoma is called trabeculectomy. It involves removing part of the eye-drainage tubes to allow fluid to drain more easily. Glaucoma surgery may be carried out under local anaesthetic while you're awake or general anaesthetic while you're asleep. Most people won't need to take eyedrops any more after trabeculectomy, and you shouldn't be in a lot of pain after surgery.
Your doctor should discuss which type of surgery they recommend, as well as any risks and benefits, before you decide whether to go ahead. These infections can occur weeks, months, or even years after the surgery. Therefore, even if it is years after the surgery, if you have early signs of infection such as redness, pain, or excessive tearing, you should call and see your ophthalmologist immediately in order to treat infection before it becomes serious.
Caught early, most infections can be adequately treated with antibiotic drops. Sometimes, the surgery can lead to eye pressures that are too low, also called hypotony. This is more common soon after the surgery. With hypotony, fluid may collect behind the retina choroidal detachment , which can cause a shadow in your peripheral or side vision.
Usually this is temporary as the pressure returns to the levels that were intended. Sometimes, however, hypotony persists and surgery must be performed in order to fix this problem. More common than eye pressure that is too low, these glaucoma surgeries may fail over time due to the natural healing or scarring tendencies of the eye, resulting in eye pressures that are higher than intended.
Sometimes, the scarring is so intense that the operation may fail to achieve a lowered pressure and you may need to restart your glaucoma medications or undergo revisions in the clinic or repeat surgery in the operating room.
Cataract formation most likely will be accelerated by glaucoma surgery, but luckily cataracts are fairly easy to fix surgically. Sometimes glaucoma surgeries are combined with cataract surgery if your ophthalmologist feels that the cataracts are having a moderate to significant impact on your vision.
However, for some glaucoma surgeries it is better to perform the glaucoma surgery alone and address the cataract later in a second operation. MIGS minimally invasive glaucoma surgery are a group of newer procedures that are usually combined with cataract surgery to lower eye pressure to the mid-teens range. In most instances, the safety profile of these procedures is higher than the more traditional glaucoma surgeries described above. However, this enhanced safety profile is counterbalanced by a more modest eye pressure reduction.
Therefore, these procedures are usually combined with cataract surgery for patients with early- to moderate-stage glaucoma. I was 34 when first diagnosed with glaucoma. Subscribe to our FREE monthly e-newsletter for the latest news, research and lifestyle articles about glaucoma.
Glaucoma Treatments. Breadcrumb Home What Is Glaucoma? It is important to be educated, informed and feel involved in your glaucoma treatment, particularly concerning eye drops; the mainstay of glaucoma treatment. Patients who are educated on the importance and goals of their treatment tend to more successfully adhere to their treatment. How is glaucoma treated?
