NYSTAGMUS

TYPES

The two types of Nystagmus are the following:

Pendular Nystagmus is the waveform of involuntary movement in the eye. It is caused by either a lack of inhibition feedback control on a neuronal circuit or an increase in latency in a feedback circuit, which subsequently causes uncontrolled movements. 

Jerk Nystagmus is a rhythmic eye movement defined by a slow drift in one side that is regularly corrected by rapid movements in the opposite direction.

SYMPTOMS

The symptoms of Nystagmus are:

• Shaking, moving, or spinning sensations
• Problems with eyesight
• Light sensitivity
• Maintaining the head in a rotated or slanted manner

DIAGNOSIS

To diagnose if you have Nystagmus, the doctor will examine your eyesight. They will make you rotate in your chair for approximately 30 seconds, then stop and attempt to look at anything. After that, the doctor will conclude whether you have Nystagmus or not. There comes a time that you will notice the slow travelling of your eyes in a specific direction. 

Other procedures may be performed on you, such as:

• Ear Examination
• Neurological Examination
• Magnetic Resonance Imaging (MRI)
• CT Scan
• Eye Movement Recording

TREATMENT

The following are some medications that alleviate the symptoms in adults but not in youngsters:

• Baclofen (Lioresal)
• Onabotulinumtoxina (Botox)
• Gabapentin (Neurontin)
• Lasik (Visian), for nearsighted people

Aside from medications, you can use suitable eye lenses or glasses to enhance your eyesight. It can assist with other eye issues that may be worsened because of Nystagmus. Eye muscle surgery, on the other hand, may be an option to treat this kind of condition.
