Primary Outcome Measures
NameTimeMethod
Change in Levels of Biomarkers After Dosing With MaxidexBaseline to 2 weeks

Biomarkers are an indicatior of inflammation. In this study, the level of biomarkers before and after anti-inflammatory treatment (Maxidex) is measured for the treatment group. In the control group, the biomarker level is measured at baseline and 2 weeks later. ddCt (Delta-Delta-Ct) is the number of polymerase chain reaction (PCR) cycles required to generate a quantifiable number.

Secondary Outcome Measures
NameTimeMethod
Correlation Between Biomarker Expression and Ocular SymptomsBaseline to 2 weeks

Correlation factor: tumor necrosis factor (TNF) messenger RNA (mRNA) vs. OSDI (Ocular Surface Disease Index).

Correlation Between Biomarker Expression and Tear Film Break up TimeBaseline to 2 weeks

Correlation factor:

TNFmRNA vs. TFBUT (Tear Film Break-up Time)

Correlation Between Biomarker Expression and NaFl (Sodium Fluorescein) StainingBaseline to 2 weeks

Correlation factor:

TNFmRNA vs. NaFl staining

Correlation Between Biomarker Expression and the Schirmer TestBaseline to 2 weeks

Correlation factor: TNFmRNA vs. Schirmer
