Treatment of Ocular Surface Inflammations

The goal of this clinical trial is to learn if topical Cyclosporine 1% works to treat severe allergic ocular surface inflammation in pediatric population. The study will evaluate the efficacy and safety of topical Cyclosporine 1%. The main questions it aims to answer are: Does topical Cyclosporine 1% lower the number of times participants need to use a rescue steroid? What medical problems do participants have when taking topical Cyclosporine 1%? Participants will: Take topical Cyclosporine 1% every day for months. Visit the clinic once every 2-6 weeks for checkups and tests. Keep a diary of their symptoms and the number of times they use a rescue medication. spelling errors/typos and update as appropriate.

OJO-miR: microRNA Expression in Allergic Conjunctivitis.

Allergic conjunctivitis (AC) causes inflammation of the conjunctiva in response to environmental allergens, affecting a significant percentage of the world population and reducing quality of life. The pathophysiology is poorly understood, lacking effective treatments. MicroRNAs have potential for diagnosing and characterizing inflammatory diseases. This study aims to compare the expression profiles of inflammation-regulating microRNAs (miR-19, miR-23, miR-125b, miR-146a, and miR-155) in serum and tear samples from subjects with AC and healthy subjects to identify biomarkers and therapeutic targets.

Treg Effector Function and Th2/Treg Ratio in Allergic Conjunctivitis: Effect of Desensitization Therapy

This study aims to evaluate the effector function and expression of TIGIT and PD-1 on Tregs, as well as the Th2/Treg ratio, in patients with allergic conjunctivitis with and without desensitization therapy, compared to healthy controls. Peripheral blood and tear samples will be collected once at enrollment. Treg and Th2 populations will be immunophenotyped, TIGIT and PD-1 expression assessed, and functional assays performed. Cytokine and antibody (IgE, IgG4) concentrations will be measured in serum and tears. Results will be analyzed using descriptive statistics, Shapiro-Wilk test for distribution, t-tests or ANOVA for group comparisons, and correlation analyses for associations, with p\<0.05 considered significant. This study seeks to identify immunological markers associated with disease severity and treatment response, potentially informing future therapeutic strategies.
