Outcome Measures

Primary Outcomes (1)

  • Tear cytokines levels

    Comparision the tear cytokines (EGF, IL-17A, IL-1β, IL-8 and TNF-α)levels in different groups using using a Milliplex Map Kit (Human Th17 Magnetic Bead Panel, Millipore, Billerica, MA).

    through study completion,an average of two weeks

Secondary Outcomes (1)

  • Clinical correlations of the tear cytokines

    through study completion,an average of two weeks

Study Arms (4)

control

subjects without dry eye and diabetes

patients with diabetes and dry eye

diabetic patients with dry eye

diabetics without dry eye syndrome

diabetic patients without dry eye

dry eye syndrome patients without diabetes

non-diabetic patients with dry eye
