Pupils & ocular motility
Colour vision
Colour vision
- Patients most commonly notice a desaturation of colours.
- Ask patient to look at a bright red object with each eye separately, and ask if the colour appears washed out in the affected eye. If so, then ask patient, "If this is 100% red (presenting object to unaffected eye), the how red is this (presenting object to affected eye)".
- Colour vision can be more formally assessed using ishihara colour plates, but that will usually be by referral to an ophthalmologist.
Visual fields - Perform confrontation field testing or refer for formal visual field tests by Ophthalmology department (Goldmann or Humphrey visual field tests)
