Assessment of Tear Functions in Patients with Acne Rosacea without Meibomian Gland Dysfunction

Purpose: To evaluate the results of tear functions in acne rosacea. Methods: This prospective study includes 64 eyes of 32 acne rosacea patients without blepharitis and meibomian gland dysfunction and 90 eyes of 45 patients as control group. Tear functions of all were evaluated with ocular surface disease index (OSDI) questionnaire, and measurements of tear osmolarity were performed by using TearLab, Schirmer I tests without anesthesia and fluorescein tear break-up time (TBUT). Results: The mean Schirmer test result was 12.53 +/- 6.54 in study group and 16.21 + 7.52 mm/5 min in control group (p = 0.28). The mean TBUT in study group was 8.21 +/- 4.01 and in control group was 18.03 +/- 6.45 s (p = 0.02). Mean tear osmolarity in study group was 304.77 +/- 15.59and in control group was 275.23 + 28.52 mOsms/L (p = 0.03). Mean OSDI score in study group was 27.51 +/- 16.73 and was 18.15 +/- 7.05 in control group (p = 0.38). Conclusions: Our study demonstrated lower dry eye tests before the appearance of clinical signs of meibomian gland disease in acne rosacea.
