Glaucoma Surgery
Glaucoma is a progressive optic neuropathy resulting from increased eye pressure, which causes visual field loss and can even lead to blindness.
Surgical intervention is considered when the patient is intolerant to medical treatment or when it is insufficient to prevent the progression of glaucoma.
There are various techniques to surgically treat this eye condition, and it is up to the ophthalmologist to recommend the most appropriate one for each case.
The most commonly used procedure is called trabeculectomy, which can be perforating or non-perforating. This operation involves finding a new outlet for aqueous humor from the eye to the outside.
With the techniques currently used, complications are rare and can be resolved within the first few days after surgery.
The most serious consequence is the loss of the effect of trabeculectomy, which involves maintaining intraocular pressure at high levels.
To achieve a less traumatic postoperative process, anti-scarring agents are sometimes administered. These are intended to limit the eye's ability to seal the fistula opened during surgery.
For a couple of years now, a series of techniques called MIGS have been under study. These techniques perform the same aqueous humor filtration procedure, but in a less aggressive manner and therefore generate fewer postoperative complications.
