Outcome Measures

Primary Outcomes (5)

  • Schirmer's test

    To assess tear secretion volume

    5 minutes

  • Tear film breakup time

    To assess tear quality

    20 seconds

  • Ocular surface status

    To assess ocular surface health status with lissamine green stain, health or corneal abrasion.

    3 minutes

  • Tear ferning

    crystal structure formed from tear drops on a slide be scored.

    30 minutes

  • Menopause related hormone Enzyme-linked immunosorbent assay (ELISA)

    To assess FSH/LH/E2/Progesterone/Mc5AC/Lactoferrin concentration between pre- and post-manopause women.

    3 hours

Secondary Outcomes (2)

  • Ocular surface disease index

    20 minutes

  • Intraocular pressure

    2 minutes

Study Arms (2)

Pre-manepausal women

NO INTERVENTION

Collect clinical information, tear and blood samples from women pre-menopause with dry eye syndrome.

Post-manepausal women

OTHER

Collect clinical information, tear and blood samples from women post-menopause with dry eye syndrome.

Other: Pre-manepausal women

Interventions

Compare tear ferning structure between pre-menopause and post-menopause women.

Also known as: Post-manepausal women
Post-manepausal women
