PURPOSE: To evaluate whether a tear substitute can improve corneal subepithelial nerve plexus and corneal sensitivity in glaucomatous patients.
METHODS: This study was prospective, longitudinal, and single arm. Twenty glaucomatous patients were recruited. All the patients were treated with a prostaglandin analog with preservative for at least 1 year. Preservative-free artificial tears (0.5% tamarind seed polysaccharide 0.5(®) eye drops single-dose preservative free [Oftagen]) were prescribed thrice per day. The participants were subjected to clinical and instrumental evaluation at baseline (T0), after 1 month (T1) and after 3 months (T3) of treatment. All patients were examined with a digital corneal confocal laser-scanning microscope (HRT II Rostock Cornea Module; Heidelberg Engineering GmbH) and Cochet-Bonnet corneal esthesiometer.
RESULTS: After the artificial substitute, corneal and conjunctival sensitivity significantly (P < 0.001) improved at T1 and T3 compared to the baseline. A significant correlation was found between break-up time and both central corneal sensitivity and the number of fibers.
CONCLUSION: The use of a preservative-free artificial substitute in association with a topical therapy with chronic preservative could increase the compliance of patients.
