NCT07592988

Brief Summary

This prospective study aims to evaluate inflammatory biomarkers in tear fluid in patients with glaucoma undergoing micropulse transscleral cyclophotocoagulation (MP-CPC), continuous-wave cyclophotocoagulation (CPC), and antiglaucoma surgeries. The study will assess the concentrations of pro- and anti-inflammatory interleukins in tear samples collected before treatment, 5-7 days after the procedure, and 1 month postoperatively. Intraocular pressure (IOP) will be measured at the same time points. The correlation between changes in interleukin levels and IOP reduction will be analyzed. Additionally, the study aims to compare inflammatory response patterns among the MP-CPC, CPC, and surgical treatment groups and to identify interleukin profiles associated with a clinically significant hypotensive effect.

Outcome Measures

Primary Outcomes (1)

  • Association Between Changes in Tear Fluid Interleukin Levels and Intraocular Pressure Reduction

    This outcome will assess the association between changes in tear fluid interleukin concentrations and the reduction in intraocular pressure after glaucoma treatment. Tear fluid levels of selected interleukins, including IL-4 and IL-6, will be measured before treatment, 5-7 days after treatment, and 1 month postoperatively. Intraocular pressure will be measured at the same time points. Correlation and regression analyses will be performed to evaluate whether changes in interleukin levels are associated with the magnitude of intraocular pressure reduction.

    Baseline, 5-7 days after treatment, and 1 month after treatment

Secondary Outcomes (3)

  • Change in Tear Fluid Interleukin Concentrations After Glaucoma Treatment

    Baseline, 5-7 days after treatment, and 1 month after treatment

  • Comparison of Inflammatory Response Patterns Between Treatment Groups

    Baseline, 5-7 days after treatment, and 1 month after treatment

  • Rate of Postoperative Complications

    Up to 1 month after treatment

Study Arms (3)

MicroPulse Transscleral Cyclophotocoagulation Group

EXPERIMENTAL

Participants in this group will undergo MicroPulse transscleral cyclophotocoagulation for the treatment of glaucoma. Tear samples and intraocular pressure measurements will be collected before treatment, 5-7 days after the procedure, and 1 month postoperatively to evaluate inflammatory biomarker changes and treatment response.

Procedure: MicroPulse Transscleral Cyclophotocoagulation

Conventional Transscleral Cyclophotocoagulation Group

ACTIVE COMPARATOR

Participants in this group will undergo conventional continuous-wave transscleral cyclophotocoagulation for the treatment of glaucoma. Tear samples and intraocular pressure measurements will be collected before treatment, 5-7 days after the procedure, and 1 month postoperatively to evaluate inflammatory biomarker changes and treatment response.

Procedure: Conventional Transscleral Cyclophotocoagulation

Antiglaucoma Surgery Group

ACTIVE COMPARATOR

Participants in this group will undergo incisional antiglaucoma surgery for the treatment of glaucoma. Tear samples and intraocular pressure measurements will be collected before surgery, 5-7 days after surgery, and 1 month postoperatively to evaluate inflammatory biomarker changes and treatment response.

Procedure: Antiglaucoma Surgery

Interventions

MicroPulse transscleral cyclophotocoagulation will be performed as a laser procedure for the treatment of glaucoma. The procedure will be applied transsclerally over the ciliary body using micropulse laser energy. Tear fluid samples will be collected before treatment, 5-7 days after the procedure, and 1 month postoperatively for assessment of interleukin levels. Intraocular pressure will be measured at the same time points.

Intraocular pressure will be measured at the same time points.

Conventional Transscleral Cyclophotocoagulation Group

Incisional antiglaucoma surgery will be performed for the treatment of glaucoma according to the clinical indication and standard surgical protocol. Tear fluid samples will be collected before surgery, 5-7 days after surgery, and 1 month postoperatively for assessment of interleukin levels. Intraocular pressure will be measured at the same time points.
