Name of the Procedure:

Destruction of Localized Lesion of Choroid (e.g., Choroidal Neovascularization); Photocoagulation (e.g., Laser), 1 or More Sessions

Summary

This procedure involves using laser technology to treat abnormal blood vessel growth in the choroid layer of the eye. It is commonly used to manage conditions like choroidal neovascularization.

Purpose

The primary purpose is to address abnormal blood vessel growth in the eye, which can lead to vision loss. The goal is to destroy these vessels, reduce leakage, and prevent further vision deterioration.

Indications

This procedure is indicated for patients experiencing:

• Abnormal blood vessel growth under the retina (choroidal neovascularization)
• Symptoms such as blurred vision, dark spots, or vision distortion
• Conditions leading to fluid leakage and retinal damage

Preparation

• Patients should follow fasting guidelines if instructed.
• Stop certain medications like blood thinners as advised.
• Undergo diagnostic tests like an Optical Coherence Tomography (OCT) scan or fluorescein angiography.
• Arrange for transportation, as vision may be impaired after the procedure.

Procedure Description

1. The patient is positioned comfortably in a reclining chair.
2. Eye drops are administered to dilate the pupil and provide local anesthesia.
3. A specialized lens is placed on the eye to focus the laser.
4. The ophthalmologist uses the laser to target and destroy abnormal blood vessels.
5. The procedure involves multiple laser bursts, which may be repeated over several sessions as needed.

Duration

The procedure typically takes 20-30 minutes per session.

Setting

Performed in an outpatient clinic, specialized eye center, or hospital.

Personnel

• Ophthalmologist (eye specialist)
• Ophthalmic nurse or assistant
• Optometrist may assist in pre and post-procedure assessments

Risks and Complications

• Common risks: Temporary discomfort, slight vision blur, or light sensitivity.
• Rare but serious complications: Retinal damage, infection, bleeding, or permanent vision changes.

Benefits

• Stabilizes or improves vision by preventing further damage.
• Reduction in symptoms such as vision distortion and dark spots.
• Benefits may be realized within a few weeks post-procedure.

Recovery

• Follow-up appointments to monitor eye health.
• Use prescribed eye drops to manage inflammation and prevent infection.
• Avoid strenuous activities and protect the eye from bright light.
• Recovery time ranges from a few days to a week with possible restrictions on activities like driving.

Alternatives

• Anti-VEGF (vascular endothelial growth factor) injections.
• Observation for minor cases.
• Pros: Injections can be effective for wet age-related macular degeneration.
• Cons: Regular injections may be needed; the laser treatment provides a direct approach.

Patient Experience

• Patients might feel slight discomfort from the light during the procedure.
• Post-procedure: Mild soreness, light sensitivity, and blurred vision.
• Pain is usually minimal and managed with over-the-counter pain relievers.
