INTRODUCTION: Optic nerve enlargement and increased velocity in superior ophthalmic vein (SOV) have been described as signs of intracranial hypertension. However, have been not so studied in patients with intracerebral haemorrhage (ICH). Our aim was to evaluate optic nerve sheath diameter (ONSD) and SOV flow by ocular duplex ultrasound (ODU) in patients with ICH and their correlation with haemorrhage volume. METHODS: Prospective study of patients with supratentorial ICH evaluated within 24 hours of onset. All patient underwent CT scan and ODU on admission. Hematoma volume was determined using the formula (longitudinalXsagittalXcoronal)/2. ONSD was measured at 5 mm of the papilla in both eyes and diameter up to 5.0 mm was considered normal. SOV was assessed over optic nerve and velocity up to 4.0 cm/sec was considered normal. Association of ONSD and SOV with ICH volume was evaluated. RESULTS: Thirty-two patients were included. Mean age was 63.7 (SD 15.6) year-old and 14 (43.8%) were male. Admission mean ICH volume was 25.9 cc (SD 28.3). All ONSD were thicker than normal. Mean Ipsilateral ONSD was 6.8 (SD 0.9) mm and contralateral 6.6 (SD 0.7) mm (p=0.506). Mean ipsilateral SOV flow was 5.6 (SD 2.7) cm/sec and contralateral was 6.4 (SD 2.5) cm/sec (p=0.155). ICH volume was linear correlated in ipsilateral (r=0.349; p=0.025) and contralateral ONSD (r=0.344; p=0.027). VSP flow did not correlate with ICH volume. CONCLUSION: ONSD measured by ODU is higher than normal in any ICH volume showing correlation with ICH volume on admission.
