Nystagmus Information, Symptoms, Treatment, Cure

Nystagmus refers to an involuntary wobbling, jittery or oscillatory movement of the eyes independent of the normal eye movement. The term nystagmus is derived from the Greek word, “nmstagmos”, which was used to describe the wobbly head movements of a sleepy or inebriated individual.
Nystagmus is usually detected in people with myopia, hyperopia or those with scars on the retina or optic nerve. Nystagmus, rarely, occurs as a result of brain tumor or neurological disorders.

Traditionally nystagmus has been divided into two groups. Sensory nystagmus, which  is related to vision loss and motor nystagmus, that is related to the control of muscle function.

Physiologic nystagmus is usually a type of involuntary eye movements that may be element in the vestibulo-ocular reflex (VOR). It really is characterized by alternating sleek pursuit in 1 path and saccadic motion inside the other area.
Horizontal optokinetic nystagmus.

Nystagmus might be brought on by subsequent foveation of moving objects, pathology, sustained rotation or substance use. For instance, if 1 fixates on the stripe of your rotating drum with alternating black and white, the gaze retreats to fixate on the new stripe because the drum moves. It is very first a rotation with a similar angular velocity, then returns in the saccade from the opposite route. The course of action proceeds indefinitely. That is optokinetic nystagmus, and is usually a resource for comprehending the fixation reflex.
