Summary

Diode laser cyclophotocoagulation effectively reduces intraocular pressure (IOP) in refractory glaucoma. This repeatable protocol offers a safe and effective treatment option for managing complex glaucoma cases.

Background:

Refractory glaucoma presents significant challenges in intraocular pressure (IOP) management.
Diode laser cyclophotocoagulation is an established treatment modality for advanced glaucoma.

Purpose of the Study:

To evaluate the efficacy and safety of a standardized diode laser cyclophotocoagulation protocol for IOP reduction in refractory glaucoma.
To assess the impact on medication usage and visual outcomes.

Main Methods:

A retrospective analysis of 58 eyes from 53 patients with refractory glaucoma.
Patients underwent diode laser cyclophotocoagulation with a repeatable standard protocol.
Follow-up ranged from 6 to 37 months (mean 19 months).

Main Results:

Mean IOP decreased from 33.0 mm Hg to 16.7 mm Hg (p < 0.0001).
Antiglaucoma medication score reduced significantly, with 91% discontinuing oral acetazolamide.
45% required repeat treatments; visual acuity decline occurred in 32% of eyes with initially good vision, associated with diabetic retinopathy.

Conclusions:

A simple, repeatable diode laser cyclophotocoagulation protocol is relatively safe and effective for IOP reduction in refractory glaucoma.
The treatment can significantly decrease medication burden.
Careful patient selection is advised due to potential visual acuity risks in specific populations.
