Purpose:
To evaluate the ocular surface alterations and tear film functions in patients with ocular Behçet disease (BD).
Methods:
This study included 48 eyes of 48 patients with inactive BD and a control group of 33 age- and sex-matched subjects. Schirmer I and tear break-up time (TBUT) tests were used to evaluate the tear film of the subjects. Impression cytology was used to evaluate morphological changes of the conjunctival surface epithelial cells.
Results:
The mean Schirmer I test result was 11.6 ± 5.9 mm/5 minutes and 16.1 ± 4.6 mm/5 minutes in the Behçet and control groups, respectively. The mean TBUT test result was 9.8 ± 5.6 seconds and 13.2 ± 5.7 seconds in the study and control groups, respectively. The Schirmer and TBUT test results were significantly lower in the study group than in the controls (P = 0.001 and P = 0.011, respectively). The mean impression cytology score was 1.3 ± 0.9 in the study group and significantly higher than the control group value of 0.4 ± 0.6 (P = 0.001).
Conclusions:
Tear film functions and conjunctival surface epithelial morphology were significantly altered in patients with ocular BD.
