hello!

my boyfriend has had 2 episodes of bilateral visual disturbances 2 months apart. He discribes them as the dark spots you get when you stand up too quickly (a scomtoma...?), which get increasingly worse over the course of half an hour or so, so much so that he finds it difficult crossing roads, and can't see his feet. He has to go to bed and gets a dull headache during and afterwards. I can't think for the life of me what it could be! Compression of optic chiasm from a space occupying lesion (please let not be this!!)?? Aura without migraine (migraine equivelent?)??. Or vascular insufficiency to the optic tract somewhere...? He personally doesn't have a history of headaches or migraine but his father and sister do.

He's a bit of a doctorphobe so any help would be muchly appreciated )

Many thanks,

Steph x
