Oscillopsia is an incapacitating condition experienced by many patients with neurological disorders. [ 2] It may be the result of ocular instability occurring after the oculomotor system is affected, no longer holding images steady on the retina.

Neurology. A demyelinating disease refers to any disease affecting the nervous system where the myelin sheath surrounding neurons is damaged. [ 1] This damage disrupts the transmission of signals through the affected nerves, resulting in a decrease in their conduction ability. Consequently, this reduction in conduction can lead to deficiencies ...
