Brief Summary

Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of the ocular surface can be achieved independent from lacrimal glands function. This prospective, open label pilot study will include 140 eyes of 70 diabetic patients diagnosed with DED and will be consecutively assigned to DQS (n=140 eyes). Participants in the DQS group will receive 3% Diquafosol ophthalmic solution. The dosage of 3% Diquafosol will be one drop, six times per day for 4 weeks. Tear film lipid layer (TFLL), non-invasive breakup time (NITBUT), corneoconjunctival staining score (CS), meibum gland (MG), conjunctival hyperemia (RS score), ocular surface disease index (OSDI) will be assessed and compared at baseline, day-14, and day-28.

Outcome Measures

Primary Outcomes (1)

  • Non-invasive tear break-up time

    Non-invasive initial tear film breaking time will be assessed using the Keratograph 5M (Oculus, Germany) topographer. Three sequentially readings will be captured, and the median value will be included in the final analysis. The median value will be recorded.

    Day-0 (baseline), 4-weeks and 8-weeks

Secondary Outcomes (9)

  • Fluorescein and lissamine conjunctival and cornea staining

    Day-0 (baseline), 4-weeks and 8-weeks
