Following on from my Horner’s Syndrome post here’s something much more useful and educational on the same subject
LITFL have a great run through of anisocoria here:
UPDATE – even since I wrote this one, LITFL has published a pretty definitive review of Horner’s. Just go read that now and stop reading this!
Particularly these videos from Sam Tapsell (the relevant Horner’s part is at 3:35)

Things I learnt:
– there is a pharmacological means of confirming a Horners (though with the apraclonidine test you need to wait an hour which is probably of no use to us)
– a transient Horner’s with cluster headaches is common
– and i finally think I know what a Homes-Adie pupil is
