Atypical presentation of malignant hypertension

A woman in her 30s presented with complaints of sudden onset of defective vision in the right eye for 2 days, with history of headache for a month. On examination, best corrected visual acuity was 20/40 in the right eye and 20/20 in the left eye. Anterior segment examination was normal. Fundus examination of both the eyes showed generalised arteriolar attenuation with diffuse, hyperaemic disc oedema and serous retinal detachment at macula in the right eye. Her blood pressure (BP) was 230/140 mm Hg. Other systemic evaluation was unremarkable. In the review visit, patient’s BP reduced to 140/100 mm Hg, and visual acuity in the right eye improved to 20/20. Fundus in the right eye showed resolving disc oedema with macular star formation, and the left eye had developed soft exudates. This seemed to confirm the diagnosis of the disc oedema being caused by hypertension and a highly asymmetrical presentation of hypertensive retinopathy.
