Detailed Description

Analyzing the difference in tear ferning structure between women pre and post-menopause with and without hormone replacement therapy (HRT). Tear and blood samples were collected for a menopause-related Enzyme-linked immunosorbent assay. Tear volume, tear osmolarity, intraocular pressure, and tear break-up time were also measured for comparison.
