After nearly drowning an 80 year old man suffers from severe hypoxia with severe brain edema. This edema leads to increased intracranial pressure. When pressure exceeds 200mmHg , the temporal lobe begins to be compressed against the tentorium cerebelli .
What is typically the first sign of such compression ?
1. Anisocoria contralateral to compression
2. anisocoria ipsilateral to compression
3. both pupils 5-6mm dilated and fixed
4. external ocular ophthalmoplegia
