Laser Iridotomy
Laser Iridotomy is a minimally invasive laser procedure that creates a small opening in the peripheral iris, allowing aqueous fluid to flow freely between the anterior and posterior chambers.
It’s mainly performed to treat or prevent angle-closure glaucoma by relieving pressure buildup inside the eye.
Overview And Clinical Background
Laser-created iris opening for pressure relief
Laser Iridotomy equalizes fluid pressure and prevents iris blockage of the drainage angle.
It’s often done prophylactically in the fellow eye to avoid future closure.
- Mechanism: Creates a small channel for fluid circulation between eye chambers.
- Indication: Used in acute or chronic angle-closure glaucoma or narrow-angle risk.
- Laser type: Nd:YAG or argon laser under topical anesthesia.
Symptoms, Signs And Presentation
Patients may present with eye pain, headache, blurred vision, or halos due to increased pressure.
Some undergo the procedure preventively before symptoms occur.
- Acute attacks: Sudden pain and redness with blurred vision.
- Chronic cases: Gradual pressure rise detected during routine exam.
- Preventive use: In narrow-angle eyes to avoid future closure.
Diagnosis Methods And Investigations
Angle and pressure assessment
Accurate diagnosis ensures safe and effective treatment.
Gonioscopy and intraocular pressure measurement guide decision-making.
- Gonioscopy: Visualizes the angle to detect closure or crowding.
- Tonometry: Measures intraocular pressure before and after the procedure.
- Anterior segment OCT: Confirms iris configuration and angle depth.
Treatment Options And Surgical Techniques
The laser procedure is quick, typically completed in under 10 minutes.
A peripheral hole is created to restore aqueous flow and prevent pressure spikes.
- Pre-treatment drops: Constrict pupil and lower pressure before laser.
- Laser delivery: Short pulses directed at iris periphery create a drainage hole.
- Post-laser care: Anti-inflammatory drops and follow-up pressure checks.
Recovery, Risks And Prognosis
Mild irritation or light sensitivity may occur temporarily.
The opening remains permanent and prevents future angle closure.
Long-term prognosis is excellent with regular monitoring.
