Your eyes see when the brain processes images from the retina, carried through the optic nerve. If this nerve is damaged at the point where it leaves the eye, the condition is referred to as glaucoma.
Glaucoma is a serious disease which can make you lose vision. The condition is caused when the pressure inside your eye increases because the fluid doesn’t drain properly. Even if this isn’t the case, your optical nerve may get damaged due to other reasons.
The biggest benefit of glaucoma surgery is to prevent the optical nerve from further damage. Alternatives do exist such as eye drops and laser treatment, but the eye surgeons at personaleyes.com.au recommend surgery because it is more effective.
Why is glaucoma surgery performed, and what benefits do you enjoy?
The most common surgical process for treating glaucoma is trabeculectomy, usually performed when both medicines and laser treatments don’t show any results. The primary benefit is that surgery reduces the pressure, preventing damage to your eyesight.
During the process, an opening is created, allowing fluid to accumulate under the eyeball tissues. The fluid is then taken up by the blood stream, reducing the pressure on the eye. In some cases, surgery may have to be performed two times for better results.
Here are the benefits for glaucoma surgery.
- Surgical treatment is more effective than other alternatives.
- If no scarring occurs, the treatment prevents glaucoma from worsening.
- Surgery decreases the pressure inside the eye because fluid begins to drain properly due to the constructed opening.
- The conjunctival tissue is used for creating a bag which collects eye fluid. Referred to as the filtering bleb, this bag passes the fluid from the eye into the blood stream. This lowers pressure.
- Contact lenses can be worn after surgery, but not immediately. Your eye surgeon can advise better, but generally, you can start using them after two weeks.
When glaucoma surgery does not help?
Trabeculectomy does have its benefits, but it’s not preferable in the following cases.
- Children who suffer from congenital glaucoma
- Diabetic patients
- Individuals who have previously undergone eye surgeries
- Patients suffering from neovascular glaucoma
Are there any risks involved?
Every surgery or treatment does have risks, but these can be mitigated through several means. Here are some of the most common risks associated with glaucoma.
The most common issue after surgery is that the opening may be scarred, preventing the fluid from draining, also interfering with bleb function. Usually, another surgery is needed to treat the issue. Scaring can be prevented by certain medicines, which your eye surgeon would prescribe.
Other common risks are bleeding, blurred vision, eye infection and increased pressure.
So should you choose surgery for glaucoma?
Talk to your eye doctor, and act on their advice. Even if they recommend surgery, it’s nothing to worry about because surgery is helpful and stops future vision loss.
