Abstract
PURPOSE: To compare the effects of cyclosporine 0.05% and 0.1% in dry eye with Sjögren's syndrome. METHODS: 120 eyes of 60 patients who have been diagnosed with Sjögren's syndrome were retrospectively enrolled. Thirty patients (group 1, 60 eyes) were treated with cyclosporine 0.1% and 30 patients (group 2, 60 eyes) with cyclosporine 0.05%. Ocular Surface Disease Index Questionnaire (OSDI), Schirmer I test, noninvasive tear break up time (NItBUT), corneal staining score, MMP 9, meibography, meibum quality and expressibility scores, tear meniscus height, and impression cytology were examined before treatment and at 1 and 3 months after treatment. RESULTS: All of dry eye signs and symptoms of both groups at 1 and 3 months were significantly improved compared with those before treatment, respectively (P < 0.05). OSDI, Schirmer I test, NItBUT, corneal and conunctival fluorescein score, MMP-9 grade, goblet cell density, and impression cytology grade of group1 were significantly improved compared with group 2 at 1 and 3 months after treatment (P < 0.05). The percentage of discontinued treatment in groups 1 and 2 was 26.7 and 3.3%, respectively. CONCLUSION: Cyclosporine 0.1% was more effective for relieving inflammatory dry eye signs and symptoms but less tolerable compared with cyclosporine 0.05% in dry eye with Sjögren's syndrome.
