Summary
Diode laser transscleral cyclophotocoagulation can rarely cause neurotrophic keratitis by damaging corneal nerves. Pre-existing risk factors like high myopia may increase this risk, necessitating adherence to treatment parameters.
Area of Science:
- Ophthalmology
- Corneal Science
- Surgical Complications
Background:
- Diode laser transscleral cyclophotocoagulation is used to treat certain eye conditions.
- Damage to corneal innervation can lead to serious complications.
- Neurotrophic keratitis is a debilitating condition affecting corneal health.
Purpose of the Study:
- To investigate the link between diode laser transscleral cyclophotocoagulation and the development of neurotrophic keratitis.
- To identify risk factors associated with this rare complication.
Main Methods:
- A case series involving 5 patients who developed neurotrophic ulcers post-diode laser transscleral cyclophotocoagulation.
- Analysis of patient characteristics, refractive status, corneal hypoesthesia risk factors, and laser treatment parameters.
Main Results:
- All 5 patients had pre-existing risk factors for corneal hypoesthesia.
- Neurotrophic keratitis developed 10-35 days after diode laser transscleral cyclophotocoagulation.
- Four patients were highly myopic and received high laser energy settings.
Conclusions:
- Neurotrophic keratitis is a rare but possible complication of diode laser transscleral cyclophotocoagulation, stemming from ciliary nerve damage.
- Pre-existing conditions like high myopia can predispose patients to this complication.
- Adhering to recommended laser treatment parameters is crucial to minimize the risk of neurotrophic keratitis.
