Glaucoma surgery: preserving the optic nerve and vision
What is glaucoma?
Glaucoma is a chronic, often silent, eye disease caused by abnormally elevated intraocular pressure (IOP), which can irreversibly damage the optic nerve. If left untreated, this can lead to progressive vision loss and even blindness.
Why glaucoma surgery?
- Failure of eye drops or laser to control IOP
- Intolerance to drug treatments
- Disease progression despite medical monitoring
The goal of surgery is to permanently reduce intraocular pressure and thus slow damage to the optic nerve.
Available surgical techniques
1. Trabeculectomy
Creation of a filtering orifice allowing the evacuation of aqueous humor and formation of a subconjunctival bubble.
2. Non-perforating deep sclerectomy
Less invasive, without completely opening the eye, reducing post-operative risks.
3. Drainage implants
Valves (Ahmed, Baerveldt, Ex-Press) for complex glaucoma or glaucoma with failed surgery.
4. Minimally invasive microsurgery (MIGS)
Micro-implants (iStent, Hydrus) for early to moderate glaucoma, via a small incision.
Procedure Details
- Local anesthesia (eye drops or injection)
- Outpatient or 1 night in hospital
- Duration: 30 to 60 minutes
- Post-operative monitoring with eye drops and IOP checks
Benefits of surgery
- Sustained reduction in intraocular pressure
- Preservation of the visual field
- Reducing or stopping eye drops
- Improving quality of life
Prognosis
Surgery cannot restore lost vision, but it can prevent future deterioration. Careful ophthalmological monitoring is essential.
