<b><i>Purpose:</i></b> To compare tear film osmolarity (TFO) between patients with diabetes mellitus (DM) and normal healthy individuals. <b><i>Methods:</i></b> In this prospective case-controlled study, the TFO in 46 normal subjects (control group) and 55 patients with DM (study group) was evaluated. TFO in milliosmole (mOsm) was measured by using an auto-osmometer. The serum levels of glycosylated hemoglobin (HbA<sub>1</sub>c) and blood glucose in all participants were also measured. Mean outcome measures were TFO and its relationship with HbA1c level and duration of DM. <b><i>Results:</i></b> Mean TFO was 320.40 ± 21.80 mOsm/l in the study group and 308.22 ± 18.16 mOsm/l in the control group (p < 0.001). The TFO values were significantly associated with duration of DM (r = 0.476, p < 0.001), but no significant correlation was found with HbA<sub>1</sub>c level (r = 0.225, p = 0.114). <b><i>Conclusions: </i></b>The study shows a significantly higher TFO in patients with DM than in the healthy controls. TFO also correlates with the duration of DM.
