To investigate the relation between pulse amplitude (PA), pulsatile ocular blood flow (POBF), and sex and hormonal status.
Measurements of POBF and PA were obtained by ocular blood flow tonography in 76 healthy subjects: 32 males and 44 females (age range 17-77 years). Females were divided into two age groups: group 1 (premenopausal) 17-42 years, and group 2 (post-menopausal) 55 years old and over. Two groups of age matched males served as controls.
Premenopausal females demonstrated a significantly higher rate of POBF and PA than age matched males and post-menopausal females.
Sex and hormonal status were shown to influence choroidal circulation.
