AST/SS: AST Combined With 0.05% Cyclosporin Eye Drop Improve Corneal Nerve Density in Patients With SS Dry Eye
Study Details
Study Description
Brief Summary
The objective of the present study was to evaluate the efficacy of autologous serum tears combined with 0.05% cyclosporin eye drop in treating Sjögren's syndrome dry eye and their effect on corneal nerves. We assessed the impact of 12-week AST combined with 0.05% cyclosporin eye drop treatment on signs, symptoms, and sub-basal nerve density (SND) in patients with dry eyes related to Sjogren's syndrome.

Detailed Description
Objective: To describe the clinical efficacy and safety of the treatment of Sjögren's syndrome dry eye using autologous serum tears combined with 0.05% cyclosporin eye drop and to evaluate their effect on corneal nerves.
Design: Singal-center, prospective, observational study. Patients and methods: Thirty eyes of fifteen patients with dry eye related to Sjögren syndrome were enrolled in this study. Following a 4-week washout period, the treatment was inverted for each patient for the same duration and treatment. Ocular Surface Disease Index (OSDI), tear film, break-up time, corneal staining with the use of fluorescein, Schirmer's test and corneal confocal microscopy were investigated.

Outcome Measures
Primary Outcome Measures
- cornea nerves [12 weeks]
cornea sub-basal nerve density
- cornea staining score [4 weeks]
to evaluate corneal epithelial repair(0= no staining; 1= less than 5 staining points; 2= more than 5 and less than 30 staining points within the range of two quadrants; and 3= staining exceeding two quadrants or staining points more than 30)
Secondary Outcome Measures
- Ocular Surface Disease Index (OSDI) [4 weeks]
to assess the quality of life and clinical symptom;The survey generated a score ranging 0-100 (0 indicated absence of eye discomfort and 100 represented maximum eye discomfort)
- Schirmer's test [4 weeks]
to assess tear flow
- tear film breakup time (TBUT) [4 weeks]
to assess tear film stability
