A careful check will exclude problems.
Sometimes the eye is impossible to examine (as
lids are shut). Refer/ask on-call eye SPR to assess.

Specific
symptoms
E.g. GCA, optic neuritis, central vision
Loss of sight on one side Differentiate eg right side of
BOTH eyes (CVA), or ONE
eye alone (eye disease)
Episodes of visual

Blurred vision with
flashes and floaters
retinal detachment/vitreous
haemorrhage
Neuro-ophthalmology
• Dilated pupil/ptosis/divergent eye
= 3rd n palsy = ?post.com.art.aneurysm
• Vertical diplopia = 4th nerve palsy
• One eye convergent = 6th nerve palsy
• Dilated pupil/normal sight = adies pupil
• Dim vision one eye = optic neuritis
(rarely tumour)
• 7th nerve palsy
3rd nerve palsy
