Tear Interleukin Biomarkers After Glaucoma Treatment

NCT07592988 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 24

No results posted yet for this study

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.

Conditions

Interventions

PROCEDURE

MicroPulse Transscleral Cyclophotocoagulation

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.

PROCEDURE

Conventional Transscleral Cyclophotocoagulation

Conventional 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.

PROCEDURE

Antiglaucoma Surgery

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.
