NCT06824844

Brief Summary

The objective of this study is to observe the effects of 0.05% cyclosporine eye drops combined with artificial tears on patients with diabetes-associated dry eye, and to monitor changes in ocular surface characteristics and inflammatory cytokines in tears before and after treatment.

Outcome Measures

Primary Outcomes (5)

  • ocular surface disease index (OSDI)

    OSDI is one of the most frequently used questionnaires for evaluation of dry eye disease (DED). This includes 12 questions which measure the frequency of symptoms over the recent week, and the scores range from 0 to 100.

    from baseline to 3 months after treatment

  • Tear break-up time (TBUT)(s)

    BUT is the time from normal blinking to the first appearance of a break in the tear film.

    from baseline to 3 months after treatment

  • Corneal fluorescein staining (CFS)

    The degree of fluorescein staining of the cornea was evaluated using the National Eye Institute (NEI) scale of five corneal regions (central, superior, temporal, nasal, and inferior). The scores range from 0 to 15.

    from baseline to 3 months after treatment

  • Schirmer I test (SIt) (mm/5 minutes)

    The Schirmer I test is performed using sterile strips without anesthesia. The strips are placed in the lateral part of the inferior fornix of the eye for 5min and the extent of tear flow down was measured in millimeters.

    from baseline to 3 months after treatment

  • Lissamine green staining

    To grade the temporal zone, the subject looks nasally; to grade the nasal zone the subject looks temporally. The upper and lower conjunctiva can also be graded.

    from baseline to 3 months after treatment

Secondary Outcomes (5)

  • corneal sensitivity (range, 60-0 mm)

    from baseline to 3 months after treatment

  • the concentration of Interleukin-1β (IL-1β) (pg/ml)

    from baseline to 3 months after treatment

  • the concentration of Interleukin-6 (IL-6) (pg/ml)

    from baseline to 3 months after treatment

  • the concentration of Interleukin-10 (IL-10) (pg/ml)

    from baseline to 3 months after treatment

  • the concentration of Interleukin-17A (IL-17A) (pg/ml)

    from baseline to 3 months after treatment
