摘要

This study aimed to compare the efficacy of topical N-acetyl-cysteine (NAC) with a topical steroid-antibiotic combination, betamethasone-sulfacetamide sodium therapy in patients with meibomian gland dysfunction (MGD).Twenty patients with MGD were prospectively randomized and assigned into 2 groups. The patients were instructed to use either NAC 5% or a topical steroid-antibiotic combination, betamethasone 0.1%-sulfacetamide sodium 10%, topically 4 times a day for a month. All patients were instructed to apply lid hygiene once daily.One month of topical therapy provided statistically significant improvements in fluorescein break-up time and Schirmer scores as compared with the initial study visit in both groups (P≤0.001). Significant improvements for the symptoms of ocular burning, itching, and intermittent filmy or blurred vision were noted in both groups at 1 month as compared with 1 day (P<0.05). Considering these rates, there was no significant difference between the groups (P>0.05). None of the patients developed an allergic reaction to the medications, and intraocular pressure measurements were within the normal limits in both groups.When used in conjunction with eyelid hygiene, topical administration of NAC appears to be as effective as a topical steroid-antibiotic combination, betamethasone-sulfacetamide sodium therapy in patients with MGD.
