Laser Peripheral Iridotomy for Glaucoma
Understanding Laser Peripheral Iridotomy
This section explains why the procedure is performed and who may benefit from it.
The laser creates a small hole in the iris so aqueous humor can move more freely, easing pressure that might otherwise damage the optic nerve.
If the spot where the iris meets the cornea narrows or closes, fluid builds up and pressure can rise quickly, placing the optic nerve at risk.
The angles look tight but no damage has occurred. A preventive iridotomy gives fluid a new exit before pressure spikes.
The narrow angle has already harmed the optic nerve. Laser iridotomy can be part of a plan to stop further damage and stabilize pressure.
A sudden blockage causes a dramatic pressure rise with pain, blurred vision, and nausea. An urgent iridotomy restores fluid flow and protects the nerve.
Inflammation or a dislocated lens can also narrow the angle. The laser may be used to improve fluid movement and lower the chance of future problems.
Comparing Treatment Options
Not every type of glaucoma is treated the same way, so choosing the right option matters.
Iridotomy is ideal for narrow or closed angles, but open-angle glaucoma often needs other approaches that focus on the eye’s natural drainage system.
For open-angle disease our ophthalmologists may recommend options such as:
- iStent
- Durysta intracameral implant
- OMNI surgical system
- iDose TR
- XEN Gel Stent
Key Benefits of Laser Iridotomy
The procedure offers several important advantages for patients with narrow angles.
Lowering eye pressure helps prevent optic nerve damage that can lead to permanent vision loss.
The new channel acts like a safety valve, reducing the risk of painful angle-closure attacks.
Iridotomy is an outpatient laser treatment with no incisions, stitches, or lengthy recovery.
Better movement of aqueous humor keeps pressure more stable and lowers the chance of progressing to full glaucoma.
While not a cure, the procedure often stops disease progression and helps preserve sight for years.
Procedure Details
Knowing what to expect makes the experience smoother and less stressful.
A laser removes a pinpoint spot of iris tissue, creating a passageway that balances pressure and keeps the iris from blocking the drainage angle.
Before treatment you may receive drops and medicine that:
- Constrict the pupil to thin the iris
- Lower eye pressure
- Numb the surface of the eye
You sit at a slit lamp while a special contact lens steadies the eye. The laser delivers brief pulses to form the opening, and the process usually takes less than ten minutes per eye.
Pressure is checked within two hours. Mild irritation or blurry vision can occur, and anti-inflammatory drops are often prescribed. Most patients resume normal activity in a day or two, with follow-up visits to be sure the opening stays clear.
Expected Recovery Experience
Most side effects are mild and improve quickly.
A scratchy feeling is common as the eye heals.
Temporary blurriness usually clears within hours or days.
Bright lights may bother the eye, so sunglasses can help until sensitivity fades.
Minor redness often improves with prescribed drops and time.
Potential Risks and When to Contact Us
Although uncommon, these issues can occur and should be monitored.
A short-term pressure rise is possible, and extra drops may be given to lower it.
Small amounts of bleeding can happen during the laser treatment but usually resolve on their own.
Glare, halos, or light streaks may appear for a short period as the eye adjusts.
In rare cases the procedure may speed up cataract development, so the lens is checked during routine visits.
The tiny hole can close over time. If it does, a repeat laser session may be needed.
