Cyclophotocoagulation is a laser procedure that reduces aqueous humour production by partially destroying the ciliary body, the tissue that makes fluid inside the eye. It is used to lower intraocular pressure in difficult or advanced glaucoma.
Methods
Transscleral cyclophotocoagulation applies laser through the white of the eye, while endoscopic cyclophotocoagulation (ECP) treats the ciliary processes from inside during intraocular surgery. Both aim to decrease pressure by limiting fluid production.
- Typically reserved for glaucoma not controlled by drops, laser, or conventional surgery
- Can be combined with cataract surgery in ECP
- Newer micropulse transscleral techniques try to reduce collateral damage
- Pain relief and anti-inflammatory medication are important post-operatively
Risks and Expectations
Because it intentionally damages ciliary tissue, cyclophotocoagulation carries risks of inflammation, pressure becoming too low, or, rarely, vision loss. It is generally considered when potential benefits outweigh these risks.
- Multiple sessions may be needed to achieve target pressure
- Patients often continue some glaucoma medication afterwards
- Follow-up monitors pressure, inflammation, and visual function
- Suitability is carefully assessed for each individual eye
