Abstract

Introduction Oestrogen has a protective effect against neurodegenerative conditions, including glaucoma and dementia. Animal models suggest that oestrogen has a vasodilatory effect, which is a possible mechanism for this. However, the full influence of oestrogen on specific cerebrovascular functions is unclear. Aims This study aims to investigate the influence of hormonal fluctuations across a healthy menstrual cycle on measures of retinal and cortical vascular functioning. Methods 27 menstruating participants (age mean[SD]=22.94[3.52] years) completed a testing session during the early-follicular, late-follicular, and mid-luteal phase of their menstrual cycle. Bloods were taken to measure circulating hormones.
