Summary
Contact diode cycloablation effectively reduced intraocular pressure in refractory glaucoma patients post-keratoplasty. While many achieved target IOP, repeat treatments were often necessary for sustained control.
Area of Science:
- Ophthalmology
- Glaucoma Management
- Corneal Surgery
Background:
- Refractory glaucoma post-penetrating keratoplasty presents a significant management challenge.
- Patients often have limited surgical options due to previous interventions.
Purpose of the Study:
- To evaluate the efficacy of contact diode cycloablation for intraocular pressure reduction.
- To assess outcomes in patients with refractory glaucoma following penetrating keratoplasty.
Main Methods:
- Retrospective, interventional case series of 28 patients.
- Contact diode cycloablation applied to 270-300 degrees.
- Postoperative outcomes including IOP, graft status, and visual acuity were monitored.
Main Results:
- Median IOP reduced from 33 mmHg to 15 mmHg (P < 0.0001).
- 79% achieved IOP between 6-21 mmHg; 57% required multiple treatments.
- Visual acuity was maintained in 61% of patients; graft opacification occurred in 16%.
Conclusions:
- Contact diode cycloablation is an effective treatment for refractory glaucoma after penetrating keratoplasty.
- The procedure offers a good safety profile and can maintain visual acuity.
- Multiple treatment sessions may be required for optimal intraocular pressure control.
