  2. Comprehensive history to look for the most reliable etilogy and to characterize the diplopia. Specially look for notion of trauma, heat intolerance, symptoms of raised intracranial pressure (nausea and vomiting, constipation, headaches). The diplopia is a binocular one, hence resolvong when closing one eye. the direction,the intensity , the evolution of the diplopia should be precised.
    Past history should notice if previous history of diplopia or any neurological deficit (multiple sclerosis hypothesis).
    Physical examination.
    Should include refraction measurement looking to astigmatism and anisometropia specially , oculomtor exams to rule out oculomotor palsy. It is important to look for sign of grave ophtalmopathy especially if notion of intermittent diplopia or diplopia at the end of the day. Completing physical examination by slit lamp exam, IOP measurement and fundoscopy should be done.
    Paraclinical exams shoud envolve red lens test, Lancaster test to confirm an oculomotor muscle palsy or limitation. Brain imaging may be urgent if oculomotor nerd palsy suspected.

  3. Thank you for this case. I’ve learned a lot, as always.
    I’d suggest you please put in parentheses the whole term for any abbreviation that you use, so that the colleagues from other countries can fully understand.

  4. This case is impressive, would you tell if in your Center perform Lumbar Punction for every patient with VI nC paresis or in every young patient who has this problem or maybe you have the suspicion based on some other subtle sign to indicate the lumbar punction?

    • This was a very interesting case.. so what are some of the treatment options you offer to patients with diplopia whilst you wait for resolution (6th cranial nerve palsy in this case).
