Severe hypertension with lone bilateral papilloedema: a variant of malignant hypertension.

Abstract：

:Patients with severe hypertension with retinoscopic bilateral papilloedema only are not classically regarded as having malignant hypertension (MHT). We have encountered 23 such patients between 1965-1993, whilst over a similar period we have seen 315 patients who fulfilled the conventional criteria for MHT with bilateral retinal haemorrhages, exudates with or without papilloedema. We hypothesised that patients with "lone" papilloedema and severe hypertension were suffering from a disease which was identical in aetiology and outcome to conventional MHT. There were no significant differences in age, mean blood pressure, proteinuria or renal function at presentation, ethnic composition, smoking status and followup blood pressure control between the papilloedema group and those presenting with conventional MHT. Clinical features at presentation in the papilloedema only group included strokes in 4, visual disturbance in 2, headaches in 3 and heart failure in 1 patient. Many patients however had no complications at presentation. After a mean followup of 59.8 months, of the "lone" papilloedema group, 7 patients (30.4%) were still alive, 1 patient was on renal dialysis therapy, 13 were dead (56.5%) and 2 (8.7%) were lost to followup. The commonest causes of death were stroke in 4 patients, renal failure in 4 and heart disease in 2. This was a similar pattern of mortality to those patients with "conventional" MHT. Lifetable analyses showed a median survival of 35.9 months for the papilloedema group which was significantly worse than the 108.7 months for the conventional MHT group (Lee-Desu statistic 4.04, p = 0.045). We suggest that patients with high blood pressure and lone bilateral papilloedema may comprise a hitherto unrecognised subgroup of patients with MHT. Once intracerebral pathology has been excluded, these patients need to be treated as aggressively as those with MHT.
