10 Optic Neuritis Symptoms
Reviewed: Dr. Mera
Symptom #8: Pulfrich Phenomenon
The Pulfrich effect is the situation where objects moving in a straight line appear to have a curved trajectory because of the different signal timings (conduction) between the two optic nerves. It can occur in cataract, multiple sclerosis, and optic neuritis.
This causes the patient to have difficulties during driving as they are unable to judge the paths of oncoming cars. Monocularly tinted spectacles in the daytime have been shown to reduce the symptoms of Pulfrich phenomenon.
