Neuro-Ophthalmology

Neuro-ophthalmology

 

Neuro-ophthalmologists manage the condition which bridge the gap between brain and eye.

This includes pseudotumour cerebri (idiopathic intracranial hypertension), optic nerve diseases and conditions which affect the eye movements causing double vision.

    Patients with unexplained loss of vision are often referred to neuro-ophthalmologists.

Common conditions seen include

  • Optic neuritis

  • Homonymous hemianopia (stroke affecting the vision)

  • Psedotumour cerebri

  • Pituitary Adenoma

  • Meningiomas

  • Giant Cell Arteritis

  • Cranial nerve palsies

  • Nystagmus

  • Optic disc drusen

  • Pseudopapilloedema

  • Horners syndrome

  • Unequal pupils

  • Visual loss associated with dementia
     

Stroke affecting the vision

 

When a stroke affects the vision one side of the visual field may be lost in both eyes. Patients often report this as having lost vision from one eye. The brain tends to fill in the missing information so some patients aren't aware they have lost vision until it is formally tested. It can be very frustrating for this group of patients to find that they can't legally drive even though they feel they can see normally.

Reading can be a challenge for patients with homonymous hemianopia. It can be difficult to find the next line, or even the next word. Holding a ruler under the line you are reading can help. Some people prefer rotating the page by 90 degrees and reading from top to bottom.
