Cyclocryotherapy in primary glaucoma: intraocular pressure reducing effects and complications

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Interventions

Background:

• Glaucoma, a leading cause of irreversible blindness, necessitates effective intraocular pressure (IOP) management.
• Chronic narrow angle glaucoma and chronic open angle glaucoma present distinct challenges for IOP control.
• Exploring alternative treatments is crucial for managing complex glaucoma cases.

Purpose of the Study:

• To evaluate the efficacy and safety of cyclocryotherapy as an alternative treatment for chronic glaucoma.
• To assess the long-term intraocular pressure control achieved with cyclocryotherapy.
• To document the complication profile associated with cyclocryotherapy in glaucoma patients.

Main Methods:

• A series of 27 eyes with chronic narrow angle and chronic open angle glaucoma underwent cyclocryotherapy.
• Intraocular pressure was monitored post-procedure.
• Follow-up duration averaged 38 months, with data on medication use and complications recorded.

Main Results:

• Successful intraocular pressure control was achieved in 91% of the treated eyes.
• A significant proportion (65%) of patients required topical anti-glaucoma medications post-treatment.
• Complications observed were predominantly minor and transient, with no serious adverse events reported.

Conclusions:

• Cyclocryotherapy demonstrates a high success rate in controlling intraocular pressure for chronic angle glaucoma.
• The procedure is associated with a favorable safety profile, characterized by minor and transient complications.
• Cyclocryotherapy represents a valuable alternative treatment option for managing chronic narrow and open angle glaucoma.
