Full-Thickness Macular Hole Surgery: A Comparison of Ten Techniques

This study compares ten modern vitreoretinal surgical techniques for full-thickness macular hole repair. Participants will be randomly assigned to one of the surgical approaches during pars plana vitrectomy, using stratified randomization based on macular hole size to ensure balanced groups. The main goal is to determine which technique provides the highest anatomical closure rate on optical coherence tomography (OCT) and the best visual outcomes. Follow-up visits are scheduled at Day 7, Month 1, and Year 1 after surgery to assess OCT findings, visual acuity, safety outcomes, and the need for reoperation.

Tear Interleukin Biomarkers After Glaucoma Treatment

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.

Morphometric Markers of the Effectiveness of Micropulse Cyclophotocoagulation

This prospective study aims to evaluate morphometric markers of treatment response following micropulse transscleral cyclophotocoagulation (MP-CPC) in patients with glaucoma. The study will assess changes in choroidal thickness and the choroidal vascularity index (CVI) measured by optical coherence tomography (OCT) before treatment, 3-7 days after the procedure, and 1 month postoperatively. Intraocular pressure (IOP) will be measured at the same time points. The correlation between changes in choroidal thickness, the choroidal vascularity index (CVI) and IOP reduction will be analyzed. Additionally, the study seeks to determine the minimal baseline choroidal thickness associated with a clinically significant hypotensive effect after MP-CPC.
