Popis: To evaluate the efficacy of topical cyclosporin A (CsA) in obstructive meibomian gland dysfunction (MGD).Prospective, randomized, single-blinded, controlled clinical study.Fifty-one patients with obstructive MGD were randomly assigned to one of two groups. The CsA group received 0.05% CsA topical nanoemulsion (Cyporin N®; Taejoon Pharm) twice daily, 0.15% hyaluronic acid eye drops four times daily, and 10 min of warm compress placement on the eyelids twice daily. In the control group, 0.15% hyaluronic acid eye drops were administered six times daily and warm compress was conducted twice daily for 10 min. The ocular surface disease index (OSDI), Schirmer 1 test, tear film break-up time (TBUT), corneal and conjunctival surface staining using fluorescein, eyelid debris and eyelid redness/swelling, upper and lower meibomian gland (MG) secretion scores, and upper and lower MG loss were assessed at the three-month visits.There were no significant differences in observed parameters between the two groups at baseline. At the three-month evaluation, the CsA group showed significantly better improvements in the TBUT, eyelid debris, eyelid redness/swelling, and lower MG secretion score (P 0.001, P 0.001, P 0.001, and P 0.001, respectively). There was no improvement in upper or lower MG loss in either group.Treatment with 0.05% CsA nanoemulsion in combination with warm compress twice daily alleviated signs of dry eyes with obstructive MGD. However, although MG secretion was improved, glandular loss could not be restored with three months of CsA nanoemulsion treatment.
