Abstract Details

Purpose:

To evaluate PRES Syndrome as an important cause of vision loss in patients with acute haemodynamic instability.

Setting:

A tertiary care multispeciality hospital in South India

Methods:

Patients with acute haemodynamic instability like acute pre-eclampsia/eclampsia/severe PIH/accelerated hypertension and presenting with sudden visual impairment were examined. Those in which the Anterior Segment was found to be normal, normal pupillary reactions and clear lens, with no major fundus anomalies, were selected. 5 patients selected were sent for MRI of brain.

Results:

MRI scanning showed T2 and FLAIR hyperintesities involving bilateral parieto-occipital regions in all the patients, suggestive of PRES Syndrome.

Conclusions:

Posterior reversible encephalopathy syndrome (PRES), is an important cause of sudden painless visual loss in patients with acute haemodynamic instability and should be kept as a differential diagnosis when examining these cases. It is caused by vasogenic oedema, commonly in the parieto-occipital region, due to hyperperfusion.
