Nd:YAG laser iridotomy in uveitic glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Uveitis Management

Background:

• Angle closure glaucoma with iris bombé presents complex management challenges.
• Uveitis can lead to significant ocular complications, including secondary glaucoma.
• Peripheral iridotomy is a common procedure for angle closure glaucoma.

Purpose of the Study:

• To evaluate the long-term survival and efficacy of Nd:YAG laser peripheral iridotomy.
• To compare iridotomy survival rates in patients with uveitis versus those without.
• To assess the impact of uveitis on the success of Nd:YAG laser peripheral iridotomy in angle closure glaucoma.

Main Methods:

• Retrospective review of 11 patients with uveitis, iris bombé, and angle closure glaucoma.
• Comparison with a control group of 65 patients with acute angle closure glaucoma without uveitis.
• Kaplan-Meier survival analysis and log rank test to compare iridotomy survival rates.

Main Results:

• In the study group, 17 out of 28 iridotomies (on 15 eyes) failed, with a median survival of 85 days.
• No failures were observed in the 66 iridotomies performed on 66 eyes in the control group.
• A statistically significant difference (P = 0.00015) in iridotomy survival was found between the groups.

Conclusions:

• Nd:YAG laser peripheral iridotomy demonstrates a high early failure rate in patients with angle closure glaucoma and iris bombé associated with uveitis.
• The presence of uveitis significantly compromises the long-term effectiveness of peripheral iridotomy in this context.
• Alternative or adjunctive treatment strategies may be necessary for managing angle closure glaucoma in patients with uveitis.
