Pre-eclampsia may have an impact on women’s health beyond their
pregnancies and has been associated with increased risks for future hypertension
and cardiovascular disease. We report a case of a patient with history of preeclampsia and emergency caesarean section at 31 weeks of gestation due to
impending eclampsia who defaulted follow up and presented with malignant
hypertension and acute loss of vision 10 years later. A 34-year-old Malay female,
presented with generalized painless reduced vision of 5 days duration which was
preceded by an intermittent headache for 1 months duration. She had a history of
pre-eclampsia during her last childbirth 10 years ago and was not started on any
antihypertensive medication as her blood pressure normalized 2 weeks post-delivery.
Subsequently, she defaulted on her follow up. Visual acuity was counting finger at 1
meter in both eyes with no relative afferent pupillary defect. Funduscopy revealed
bilateral grade IV hypertensive retinopathy with the presence of optic disc swelling
and macular star. Optical coherence tomography showed bilateral sub-retinal fluid at
the macula. Her blood pressure was 255/168 mmHg with other systemic
examinations being normal. Ultrasonography of the kidneys showed the presence of
bilateral renal parenchymal disease with elevation of serum urea and creatinine
levels. Her blood pressure was controlled with triple oral antihypertensive agents. Her
vision improved to 6/36 and 6/6 with a pinhole in both eyes and resolution of
papilloedema and sub-retinal fluid at three months follow-up. Patients with a history
of pre-eclampsia must be closely monitored during the postpartum period. Even
though her blood pressure was normalized, careful monitoring and long-term medical
follow up plan must be clearly explained to the patient as she might develop chronic
or essential hypertension afterward. Our patient most likely had essential
hypertension superimposed with pre-eclampsia during her last pregnancy and
currently presented with malignant hypertension due to undiagnosed chronic
hypertension as she defaulted her medical follow up.
