Summary
Menopause does not significantly alter corneal curvature, though estrogen levels correlate with minor horizontal curvature changes in postmenopausal women. This study used computerized videokeratography to assess these effects.
Area of Science:
- Ophthalmology
- Endocrinology
- Women's Health
Background:
- Menopause is a significant physiological transition in women's lives.
- Hormonal changes during menopause may influence various bodily tissues, including the cornea.
- Corneal topography changes in relation to menopause are not well-established.
Purpose of the Study:
- To investigate the impact of menopause on corneal curvature.
- To compare corneal topography in premenopausal and postmenopausal women using computerized videokeratography (CVK).
Main Methods:
- A prospective study comparing 36 postmenopausal women with 26 healthy premenopausal controls.
- Hormonal levels (FSH, LH, Estradiol, Progesterone) were assessed to confirm menopausal status.
- Comprehensive ophthalmic examinations and CVK were performed on all participants.
Main Results:
- No statistically significant differences in mean horizontal or vertical corneal curvature were found between premenopausal and postmenopausal groups.
- Mean keratometric astigmatism was similar between the two groups.
- A significant negative correlation was observed between horizontal corneal curvature and estrogen levels in postmenopausal women.
Conclusions:
- Menopause, as a physiological process, may be associated with subtle corneal topographic alterations.
- Minimal corneal steeping was observed in postmenopausal women compared to premenopausal women.
- Estrogen level fluctuations during menopause appear to be linked to slight modifications in the horizontal corneal curvature.

Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
