About this trial
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.

Treatments tested in this trial
MicroPulse Transscleral Cyclophotocoagulation
Procedure/SurgeryMicroPulse 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.
Conventional Transscleral Cyclophotocoagulation
Procedure/SurgeryConventional continuous-wave 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 continuous-wave 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.
Antiglaucoma Surgery
Procedure/SurgeryIncisional 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.

Trial outcomes
Primary outcomes
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.
Secondary outcomes
Change in Tear Fluid Interleukin Concentrations After Glaucoma Treatment
This outcome will evaluate temporal changes in tear fluid interleukin concentrations after different glaucoma treatment modalities, including MicroPulse transscleral cyclophotocoagulation, conventional transscleral cyclophotocoagulation, and incisional antiglaucoma surgery. Tear fluid samples will be collected at baseline, 5-7 days after treatment, and 1 month postoperatively.
Comparison of Inflammatory Response Patterns Between Treatment Groups
This outcome will compare postoperative inflammatory biomarker patterns between the MicroPulse transscleral cyclophotocoagulation group, conventional transscleral cyclophotocoagulation group, and incisional antiglaucoma surgery group. Differences in tear fluid interleukin levels and their postoperative dynamics will be analyzed between the groups.
Rate of Postoperative Complications
This outcome will assess the rate of postoperative complications after glaucoma treatment, including hypotony, corneal edema, hyphema, iritis, vitreous hemorrhage, cystoid macular edema, ocular surface inflammation, and other procedure-related adverse events.
