3. What is amaurosis fugax?


Neuro-ophthalmology Question of the Week: Visual Aura of Migraine

1. Headache, scalp tenderness, jaw claudication, and diplopia suggest?
2. Eye or brow pain suggests?
3. Neck pain suggests?

Neuro-ophthalmology Question of the Week – Vision Loss

Question: Which of the following are correct?
1. If visual acuity can be improved by the patient looking through a pinhole, the problem is refractive or ocular, not neurologic in origin.
2. Reduction in the saturation or brightness of colors may be an early sign of optic nerve disease.
3. A relative afferent pupillary defect ipsilateral to visual loss indicates an optic neuropathy or severe retinal disease (in which case the retina looks abnormal on funduscopic examination).
4. If nonorganic visual loss is suspected, normal stereovision indicates 20/20 visual acuity in both eyes.
5. A positive response to the optokinetic nystagmus stimulus indicates a visual acuity of at least 20/400 in the eye tested.

Neuro-ophthalmology Question of the Week: Electroretinography

Which of the following statements are correct?
1. Full-field ERG is useful in detecting diffuse retinal disease in the setting of generalized or peripheral vision loss.
2. The ERG is invariably severely depressed by the time patients complain of visual loss.
3. In full-field ERG the responses cannot be substantially altered voluntarily.
4. The full-field ERG may be normal in minor or localized retinal disease, particularly maculopathies, even with severe visual acuity loss.
5. Multifocal ERG is extremely helpful in detecting occult focal retinal abnormalities within the macula.
6. Uncooperative patients can alter the responses on a multifocal ERG by not fixating accurately.
