Summary
Cyclocryotherapy for glaucoma can lead to severe anterior segment necrosis, a rare complication. This case highlights the risk of necrosis and subsequent expulsive choroidal hemorrhage following the procedure.
Area of Science:
- Ophthalmology
- Surgical Complications
- Glaucoma Treatment
Background:
- Cyclocryotherapy is a treatment for refractory glaucoma.
- Anterior segment ischemia is a known, though uncommon, complication.
- Previous reports have not detailed anterior segment necrosis post-procedure.
Observation:
- A 74-year-old woman with secondary glaucoma received cyclocryotherapy.
- Ten weeks post-procedure, she developed anterior segment necrosis and dehiscence at the cryotherapy sites.
Findings:
- The anterior segment necrosis led to an expulsive choroidal hemorrhage.
- This represents the first reported instance of anterior segment necrosis as a direct complication of cyclocryotherapy.
Implications:
- Clinicians should be aware of the risk of anterior segment necrosis after cyclocryotherapy.
- This complication can lead to severe outcomes, including expulsive choroidal hemorrhage.
- Further research may be needed to understand and mitigate this rare complication.
