Abstract: PCOS & dry eye (or not)


This study seems to have found a much poorer correlation between PCOS and dry eye than one or two earlier ones.


Purpose:
To evaluate the tear osmolarity and ocular surface changes in patients with polycystic ovary syndrome (PCOS).
 Materials and Methods:
Forty-eight patients with recently diagnosed PCOS and thirty-three control volunteers were enrolled in this prospective, observational study. Ocular surface disease index (OSDI) score was calculated. Tear osmolarity was measured using the TearLab Osmolarity System (Tearlab, San Diego, CA, USA). All subjects also underwent the following ophthalmologic evaluation: Schirmer I test, tear-film breakup time (TBUT), ocular surface flourescein staining, and conjunctival impression cytology.
 Results:
Mean OSDI score was significantly higher in patients with PCOS than control subjects (P = 0.001). Tear osmolarity was similar in both groups (P = 0.404). There were no significant differences between groups in Schirmer I test results, TBUT, and ocular surface flourescein staining scores (P > 0.05). Compared to control group, a statistically significant squamous metaplasia was observed in temporal bulbar conjunctival impression cytology specimens in PCOS group (P = 0.032).
 Conclusions:
In patients with recently diagnosed PCOS, tear volume and osmolarity are not affected but, conjunctival morphology may be affected, though on a limited scale.
