Sex hormones impact ocular surface health and dry eye disease. Research explores the role of estrogen and androgens in dry eye, investigating hormonal therapies for improved eye function.

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Ocular Surface Disease

Background:

  • Sex steroids (estrogen and androgens) influence ocular surface homeostasis via receptors on corneal, conjunctival, and Meibomian gland tissues.
  • Ocular surface dysfunction leads to dry eye, a prevalent inflammatory condition exacerbated by aging and more common in females.
  • Post-menopausal endocrine shifts contribute to dry eye pathogenesis, but the specific roles of estrogen/androgen deficiency or imbalance remain debated.

Purpose of the Study:

  • To investigate the role of hormonal status, specifically sex steroids, in ocular surface homeostasis and dry eye.
  • To clarify the controversial effects of hormonal replacement therapy on dry eye symptoms and tear function.
  • To evaluate the potential of estrogen or androgen-based eye drops as an innovative dry eye treatment.

Main Methods:

  • Review of scientific literature on hormonal status and ocular surface function.
  • Analysis of the role of estrogenic and androgenic receptors in ocular tissues.
  • Examination of the impact of aging and menopausal endocrine changes on dry eye.

Main Results:

  • Sex steroids are integral to ocular surface maintenance throughout life.
  • Dry eye is more prevalent in females and increases with age, with hormonal changes playing a role in post-menopausal women.
  • The therapeutic versus promoting effect of hormone replacement therapy on dry eye remains controversial.

Conclusions:

  • Hormonal status significantly impacts ocular surface health and dry eye development.
  • Further research is needed to elucidate the precise mechanisms of sex steroid action and the efficacy of hormonal therapies.
  • Estrogen or androgen-based topical treatments show promise for managing dry eye disease.
