Summary

Introduction: Glaucoma is the second leading cause of blindness globally. Most anti-hypertensive drops contain preservatives harmful to the corneal epithelium, with up to 78% of treated patients reporting dry eye symptoms. Autologous serum eye drops (ASED), contains essential growth factors and nutrients which may promote corneal and conjunctival integrity, offering benefits over traditional treatments. This study investigates the efficacy of 20% ASED over placebo in the treatment of corneal epitheliopathies in patients with glaucoma treated with antihypertensive drops.

Methods: The present study is a triple-blinded, randomized controlled trial that anticipates to enroll 25 patients (50 eyes) with bilateral corneal epitheliopathy secondary to antihypertensive glaucoma treatments. Patients will receive autologous serum eye drops in one eye and placebo in the contralateral eye for two months, in addition to standard artificial tears treatment.

The primary outcome is the comparison of National Eye Institute (NEI) scores between autologous serum drops and placebo-treated eyes at two months. Secondary outcomes include Schirmer's test scores, visual acuity, tear break-up time (TBUT), Ocular Surface Disease Index (OSDI) scores, intraocular pressure, and complication rates.

The study aims to analyze the effectiveness of autologous serum eye drops in treating corneal epitheliopathies in glaucoma patients, potentially offering a new therapeutic avenue.
