# What is endocyclophotocoagulation (ECP)?

Endocyclophotocoagulation ECP is a laser procedure that targets the ciliary body inside the eye to reduce fluid production and lower pressure in glaucoma.

## How ECP works

Using an endoscopic probe inserted through a small incision, the surgeon applies laser energy directly to the ciliary processes. This decreases aqueous humour production.

- Often combined with cataract surgery in open-angle glaucoma
- Performed under local or general anaesthetic
- Laser treatment is titrated to avoid excessive tissue damage
- Can be repeated or combined with other glaucoma procedures

## Expected outcomes and risks

ECP offers a way to lower pressure without creating a drainage bleb. It may be suitable for patients where additional outflow surgery is not ideal.

- Pressure reduction is typically moderate
- Inflammation and temporary pressure spikes can occur after surgery
- Long-term follow-up is needed to assess effectiveness
- Some patients continue glaucoma drops despite improvement
