Effects of systemic anti-androgen drugs on the ocular surface.

To investigate the effect of systemic anti-androgen drugs on tear function tests and the ocular surface. Sixty-four male subjects were included in this study. Subjects who were on anti-androgen treatment for prostate cancer (Group A, n: 31) and those who had received only surgical treatment for prostate cancer (Group B, n: 17) were recruited from the department of urology. Age-matched subjects who had never received anti-androgen treatment (Group C, n: 16) constituted the control group. Group A was divided into two subgroups according to the number of anti-androgen drugs used (Group A1: one drug, Group A2: two drugs). All cases underwent a complete ocular examination, including tear film break up time (TBUT), corneal and conjunctival staining, Schirmer 1 test, conjunctival impression cytology, and ocular surface disease index (OSDI) questionnaire. The mean Schirmer's values were 6.87mm, 11.41mm, and 13.03mm in Groups A, B, and C, respectively (P=0.001). TBUT was 5.45±2.01, 9.85±2.52 and 9.81±1.96seconds in Groups A, B, and C, respectively (P=0.001). Schirmer and TBUT were significantly lower, and corneal staining and OSDI questionnaire scores were higher in Group A compared to groups B and C (P<0.01). Conjunctival impression cytology results according to the Nelson grading system revealed no statistically significant difference between the groups (P=0.422). Anti-androgen drugs alter tear function tests, cause increased corneal and conjunctival staining scores and worsen complaints of dry eye in patients with prostate cancer.
