What is Laser Iridotomy?
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.Laser iridotomy is a surgical procedure primarily used to treat angle-closure glaucoma and certain other conditions affecting intraocular pressure. This minimally invasive technique plays a crucial role in preventing acute glaucoma attacks and preserving vision.
Angle-closure glaucoma occurs when the drainage angle of the eye becomes blocked, leading to a rapid increase in intraocular pressure. This can result in severe eye pain, headaches, nausea, vomiting, and, if untreated, can lead to permanent vision loss. Laser iridotomy helps to create an alternative pathway for aqueous humor (the fluid in the eye), alleviating pressure and reducing the risk of complications.
The Procedure
Preparation
- Prior to the procedure, patients undergo a comprehensive eye examination. This includes measuring intraocular pressure, assessing the drainage angle, and evaluating overall eye health.
- Patients may receive specific instructions regarding eating and drinking before the procedure.
Anesthesia
Laser iridotomy typically involves the use of local anesthesia to numb the eye. This ensures that patients remain comfortable during the procedure.
Procedure Steps
- The ophthalmologist uses a specialized laser to create a small hole in the peripheral part of the iris. This hole acts as a new drainage pathway for the aqueous humor.
- The procedure usually lasts about 15 to 30 minutes and is often performed on an outpatient basis. Patients may experience a brief sensation of pressure but minimal discomfort.
Post-Procedure Monitoring
- After the procedure, patients are monitored for a short period to ensure there are no immediate complications.
- In some cases, patients may need to stay in the clinic for a brief observation period.
Indications for Laser Iridotomy
Laser iridotomy is primarily indicated for:
- Angle-Closure Glaucoma: To prevent acute attacks by creating an alternate drainage route.
- Pupillary Block: A condition where the iris obstructs the drainage of fluid, potentially leading to increased pressure.
- High-Risk Conditions: Patients with anatomical features that predispose them to angle-closure glaucoma may benefit from preventive iridotomy, even in the absence of elevated pressure.
Risks and Complications
While laser iridotomy is generally safe, there are potential risks associated with the procedure:
- Intraocular Pressure Fluctuations: Some patients may experience temporary increases in intraocular pressure after the procedure.
- Vision Changes: There may be transient visual disturbances, such as halos around lights, particularly at night.
- Incomplete Procedure: In some cases, the iridotomy may not adequately relieve pressure, necessitating further treatment.
- Infection: Although rare, infection at the site of the procedure is a possibility.
Recovery and Follow-Up
- Immediate Recovery: Most patients can return to their normal activities shortly after the procedure, but they should avoid strenuous activities for a few days.
- Follow-Up Appointments: Regular follow-up visits are essential to monitor intraocular pressure and ensure the effectiveness of the procedure. During these visits, the ophthalmologist will assess the healing process and the overall health of the eye.
