AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for women who have just given birth. One group had high blood pressure in pregnancy. The other group had a normal-blood-pressure pregnancy.
- Age
- 18 years or older
- Sex
- Women only
- Disease stage
- Exposed group: a hypertensive disorder of pregnancy (ISSHP 2018 criteria), such as pre-eclampsia, gestational hypertension, chronic hypertension, eclampsia or HELLP syndrome, or new high blood pressure or pre-eclampsia within 48 hours of delivery. Comparison group: a pregnancy without high blood pressure problems.
Main reasons for not taking part
- Eye disease affecting the orbital circulation (glaucoma, proliferative retinopathy, previous orbital surgery or eye injury)
- Known carotid artery narrowing or a previous stroke or other cerebrovascular event
- Significant structural heart disease
- Known chronic kidney disease stage 3 or above
- Diabetes with organ damage

Hypertensive disorders of pregnancy frequently fail to resolve at delivery. A substantial proportion of women remain hypertensive at the six-week postnatal review, postpartum eclampsia occurs days to weeks after birth, and a minority show persisting renal dysfunction.

Ophthalmic Artery Doppler in the Puerperium and Maternal Outcomes After Hypertensive Disorders of Pregnancy: a Prospective Cohort Study
Hypertensive disorders of pregnancy frequently fail to resolve at delivery. A substantial proportion of women remain hypertensive at the six-week postnatal review, postpartum eclampsia occurs days to weeks after birth, and a minority show persisting renal dysfunction. Attendance at postnatal follow-up is nonetheless poor and specialist resources are limited, so a simple bedside test that identified the women whose cardiovascular recovery is incomplete would allow surveillance to be targeted.
Ophthalmic artery Doppler is non-invasive, takes about five minutes and requires only a linear transducer already present in obstetric units. Its antenatal performance is well characterised, but a systematic review by this group (PROSPERO CRD420261488689) identified only three studies in thirty years addressing the postpartum period, two of which included a normotensive comparator, totalling 131 women. None reported a threshold or any measure of diagnostic accuracy, and none recorded antihypertensive treatment at the time of scanning.
This prospective cohort study will measure ophthalmic artery Doppler indices at four timepoints between delivery and three months in women with hypertensive disorders of pregnancy and in normotensive controls, and will determine whether the peak systolic velocity ratio measured 24 to 48 hours after delivery predicts persistent hypertension at the six-week postnatal review.
Inclusion: Exposed Cohort; Age 18 years or older; Hypertensive disorder of pregnancy diagnosed by ISSHP 2018 criteria: pre-eclampsia, gestational hypertension, chronic hypertension, chronic hypertension with superimposed pre-eclampsia, eclampsia or HELLP syndrome; Or de novo postpartum hypertension or pre-eclampsia arising within 48 hours of delivery after a normotensive pregnancy; Delivery at a participating centre, at any gestational age and by any mode of delivery; Written informed consent; Comparison cohort:; Age 18 years or older; Normotensive pregnancy without hypertensive complications; Delivery at a participating centre; Written informed consent; Enrolled concurrently at a 1:2 ratio relative to the exposed cohort, matched by age band and parity.
Exclusion: Known ocular disease affecting the orbital circulation: glaucoma, proliferative retinopathy, previous orbital surgery or ocular trauma; Known carotid artery stenosis or previous cerebrovascular event; Significant structural heart disease; Known chronic kidney disease stage 3 or above; Diabetes mellitus with end-organ damage; Inability to undergo the examination because of clinical instability or refusal; Foreseeable inability to complete follow-up; Inability to give informed consent.
