Congenital nystagmus has traditionally been viewed as non-treatable, but medications have been discovered in recent years that show promise in some patients. In 1980, researchers discovered that a drug called baclofen could effectively stop periodic alternating nystagmus. Subsequently, gabapentin, an anticonvulsant, was found to cause improvement in about half the patients who received it to relieve symptoms of nystagmus. Other drugs found to be effective against nystagmus in some patients include memantine, levetiracetam, 3,4-diaminopyridine (available in the US to eligible patients with downbeat nystagmus at no cost under an expanded access program), 4-aminopyridine, and acetazolamide. Several therapeutic approaches, such as contact lenses, drugs, surgery, and low vision rehabilitation have also been proposed. For example, it has been proposed that mini-telescopic eyeglasses suppress nystagmus.

Surgical treatment of Congenital Nystagmus is aimed at improving the abnormal head posture, simulating artificial divergence or weakening the horizontal recti muscles. Clinical trials of a surgery to treat nystagmus (known as tenotomy) concluded in 2001. Tenotomy is now being performed regularly at numerous centres around the world. The surgery developed by Louis F. Dell'Osso Ph.D. aims to reduce the eye shaking (oscillations), which in turn tends to improve visual acuity.

Acupuncture has conflicting evidence as to having beneficial effects on the symptoms of nystagmus. Benefits have been seen in treatments where acupuncture points of the neck were used, specifically points on the sternocleidomastoid muscle. Benefits of acupuncture for treatment of nystagmus include a reduction in frequency and decreased slow phase velocities which led to an increase in foveation duration periods both during and after treatment. By the standards of evidence-based medicine, the quality of these studies can be considered poor (for example, Ishikawa has a study sample size of just six, is unblinded and without proper control), and given high quality studies showing that acupuncture has no effect beyond placebo, the results of these studies have to be considered clinically irrelevant until higher quality studies are produced.

Physical therapy or Occupational therapy is also used to treat nystagmus. Treatment consist of learning compensatory strategies to take over for the impaired system.

Treatment is usually unnecessary. In severe cases, surgery with a bilateral levator excision and frontalis brow suspension may be used.

The usual treatment of a standardised Adie syndrome is to prescribe reading glasses to correct for impairment of the eye(s). Pilocarpine drops may be administered as a treatment as well as a diagnostic measure. Thoracic sympathectomy is the definitive treatment of diaphoresis, if the condition is not treatable by drug therapy.

There is no treatment of conjugate gaze palsy itself, so the disease or condition causing the gaze palsy must be treated, likely by surgery. As stated in the causes section, the gaze palsy may be due to a lesion caused by stroke or a condition. Some of the conditions such as Progressive supra nuclear palsy are not curable, and treatment only includes therapy to regain some tasks, not including gaze control. Other conditions such as Niemann-Pick disease type C have limited drug therapeutic options. Stroke victims with conjugate gaze palsies may be treated with intravenous therapy if the patent presents early enough, or with a surgical procedure for other cases.

Although treatment may be unnecessary, there may be social implications, especially in young children when venturing from a supportive home environment to a public environment (e.g., starting school). Continued support, including monitoring behavior and educating the child about his or her appearance as seen by others, is encouraged. Gradual or sudden withdrawal from interaction with others is a sign that may or may not be related to such behavior. Studies are being conducted to elucidate these implications.

Treatment and prognosis depend on the underlying condition. For example, in thiamine deficiency, treatment would be the immediate administration of vitamin B1.

The majority of patients remain symptom free and able to maintain binocularity with only a slight face turn. Amblyopia is uncommon and, where present, rarely dense. This can be treated with occlusion, and any refractive error can also be corrected.

Duane syndrome cannot be cured, as the "missing" cranial nerve cannot be replaced, and traditionally there has been no expectation that surgery will result in any increase in the range of eye movement. Surgical intervention, therefore, has only been recommended where the patient is unable to maintain binocularity, where they are experiencing symptoms, or where they are forced to adopt a cosmetically unsightly or uncomfortable head posture in order to maintain binocularity. The aims of surgery are to place the eye in a more central position and, thus, place the field of binocularity more centrally also, and to overcome or reduce the need for the adoption of an abnormal head posture. Occasionally, surgery is not needed during childhood, but becomes appropriate later in life, as head position changes (presumably due to progressive muscle contracture).

Surgical approaches include:

- Medial rectus recession in the involved eye or both eyes. By weakening the medial rectus muscles this procedure improves the crossed-eye appearance but does not improve outward eye movements (abductions).

- Morad et al. showed improved abduction after modest unilateral medial rectus recession and lateral rectus resection in a subgroup of patients with mild eye retraction and good adduction before surgery.

- Lateral transposition of the vertical muscles described by Rosenbaum has been shown to improve range of movement of the eye. The surgical procedure produces 40-65 degrees of binocular field. Orbital wall fixation of the lateral rectus muscle (muscle is disinserted and reattached to lateral orbital wall) is recommended an effective method to inactivate a lateral rectus muscle in cases of marked anomalous innervation and severe cocontraction.

The first aims of management should be to identify and treat the cause of the condition, where this is possible, and to relieve the patient's symptoms, where present. In children, who rarely appreciate diplopia, the aim will be to maintain binocular vision and, thus, promote proper visual development.

Thereafter, a period of observation of around 9 to 12 months is appropriate before any further intervention, as some palsies will recover without the need for surgery.

This is most commonly achieved through the use of fresnel prisms. These slim flexible plastic prisms can be attached to the patient's glasses, or to plano glasses if the patient has no refractive error, and serve to compensate for the inward misalignment of the affected eye. Unfortunately, the prism only correct for a fixed degree of misalignment and, because the affected individual's degree of misalignment will vary depending upon their direction of gaze, they may still experience diplopia when looking to the affected side. The prisms are available in different strengths and the most appropriate one can be selected for each patient. However, in patients with large deviations, the thickness of the prism required may reduce vision so much that binocularity is not achievable. In such cases it may be more appropriate simply to occlude one eye temporarily. Occlusion would never be used in infants though both because of the risk of inducing stimulus deprivation amblyopia and because they do not experience diplopia.

Other management options at this initial stage include the use of botulinum toxin, which is injected into the ipsilateral medial rectus (botulinum toxin therapy of strabismus). The use of BT serves a number of purposes. Firstly, it helps to prevent the contracture of the medial rectus which might result from its acting unopposed for a long period. Secondly, by reducing the size of the deviation temporarily it might allow prismatic correction to be used where this was not previously possible, and, thirdly, by removing the pull of the medial rectus it may serve to reveal whether the palsy is partial or complete by allowing any residual movement capability of the lateral rectus to operate. Thus, the toxin works both therapeutically, by helping to reduce symptoms and enhancing the prospects for fuller ocular movements post-operatively, and diagnostically, by helping to determine the type of operation most appropriate for each patient.

Since this condition is usually coupled with other neurological disorders or deficits, there is no known cure for cerebral polyopia. However, measures can be taken to reduce the effects of associated disorders, which have proven to reduce the effects of polyopia. In a case of occipital lobe epilepsy, the patient experienced polyopia. Following administration of valproate sodium to reduce headaches, the patient’s polyopia was reduced to palinopsia. Further, after administering the anticonvulsant drug Gabapentin in addition to valproate sodium, the effects of palinopsia were decreased, as visual perseveration is suppressed by this anticonvulsant drug. Thus, in cases of epilepsy, anticonvulsant drugs may prove to reduce the effects of polyopia and palinopsia, a topic of which should be further studied.

In other cases of polyopia, it is necessary to determine all other present visual disturbances before attempting treatment. Neurological imaging can be performed to determine if there are present occipital or temporal lobe infarctions that may be causing the polyopia. CT scans are relatively insensitive to the presence of cerebral lesions, so other neurological imaging such as PET and MRI may be performed. The presence of seizures and epilepsy may also be assessed through EEG. In addition, motor visual function should be assessed through examination of pupillary reactions, ocular motility, optokinetic nystagmus, slit-lamp examination, visual field examination, visual acuity, stereo vision, bimicroscopic examination, and funduscopic examination. Once the performance of such functions have been assessed, a plan for treatment can follow accordingly. Further research should be conducted to determine if the treatment of associated neurological disturbances can reduce the effects of polyopia.

While preventive measures, such as taking breaks from activities that cause eye strain are suggested, there are certain treatments which a person suffering from the condition can take to ease the pain or discomfort that the affliction causes. Perhaps the most effective of these is to remove all light sources from a room and allow the eyes to relax in darkness. Free of needing to focus, the eyes will naturally relax over time, and relieve the discomfort that comes with the strain. Cool compresses also help to some degree, though care should be taken to not use anything cold enough to damage the eyes themselves (such as ice). A number of companies have released "computer glasses" which, through the use of specially tinted lenses, help alleviate many of the factors which cause eye strain, though they do not completely prevent it. Rather, they just make it harder to strain the eye.

The prognosis of a lesion in the visual neural pathways that causes a conjugate gaze palsy varies greatly. Depending on the nature of the lesion, recovery may happen rapidly or recovery may never progress. For example, optic neuritis, which is caused by inflammation, may heal in just weeks, while patients with an ischemic optic neuropathy may never recover.

Currently there is no cure for dysmetria itself as it is actually a symptom of an underlying disorder. However, isoniazid and clonazepam have been used to treat dysmetria. Frenkel exercises treat dysmetria. There have also been numerous reported cases of chiropractic neurology as an effective holistic treatment for dysmetria. Cannabis has been used in trials in the U.K. and displayed some success, though it is not legal to use in some U.S. states.

Adie's syndrome is not life-threatening or disabling. As such, there is no mortality rate relating to the condition; however, loss of deep tendon reflexes is permanent and may progress over time.

Medication is often not necessary in children as symptoms usually alleviate spontaneously as the child ages. However, because the disorder may affect wakeful behavior, many adults who continue to suffer from RMD may seek treatment. Benzodiazepines or tricyclic antidepressants have been considered as therapeutic options in managing the disorder. Infantile and adolescent RMD respond well to low doses of clonazepam. Prescription medications such as ropinirole or pramipexole given to restless legs syndrome patients do not show any clinical improvement in many patients with RMD.

There is no consistently effective medication for SMD, and there is little evidence for any effective treatment. In non-autistic or "typically developing children", habit reversal training may be useful. No treatment is an option when movements are not interfering with daily life.

Before prescribing medication for these conditions which often resolve spontaneously, recommendations have pointed to improved skin hygiene, good hydration via fluids, good nutrition, and installation of padded bed rails with use of proper mattresses. Pharmacological treatments include the typical neuroleptic agents such as fluphenazine, pimozide, haloperidol and perphenazine which block dopamine receptors; these are the first line of treatment for hemiballismus. Quetiapine, sulpiride and olanzapine, the atypical neuroleptic agents, are less likely to yield drug-induced parkinsonism and tardive dyskinesia. Tetrabenazine works by depleting presynaptic dopamine and blocking postsynaptic dopamine receptors, while reserpine depletes the presynaptic catecholamine and serotonin stores; both of these drugs treat hemiballismus successfully but may cause depression, hypotension and parkinsonism. Sodium valproate and clonazepam have been successful in a limited number of cases. Stereotactic ventral intermediate thalamotomy and use of a thalamic stimulator have been shown to be effective in treating these conditions.

Treatment of sleep apnea via a continuous positive airway pressure (CPAP) device has shown dramatic improvement in apnea and nearly complete resolution of RMD symptoms. Behavioral interventions may alleviate some RMD symptoms and movements. In such a therapy, sufferers are asked to perform RMD-like motions during the day in a slow and methodic manner. In such, patients come short of full rhythmic movements that they experience in sleep. Such behavioral training has been shown to carry over into sleep, and the forcefulness of the RMD movements is reduced or eliminated. Hypnosis and sleep restriction have been used in some cases to good effect.

The cause for pathological nystagmus may be congenital, idiopathic, or secondary to a pre-existing neurological disorder. It also may be induced temporarily by disorientation (such as on roller coaster rides) or by certain drugs (alcohol and other central nervous system depressants, inhalant drugs, stimulants, psychedelic drugs, and dissociative drugs).

Botox (botulinum toxin) is a new and versatile tool for the treatment of synkinesis. Initially used for reducing hyperkinesis after facial palsy, Botox was later attempted on patients with post-facial palsy synkinesis to reduce unwanted movements. The effects of Botox have shown to be remarkable, with synkinetic symptoms disappearing within 2 or 3 days. The most common treatment targets are the orbicularis oculi, depressor anguli oris (DAO), mentalis, platysma and the contralateral depressor labii inferioris muscles. Due to the short span of Botox effects though, patients must come back to the doctor for re-injection approximately every 3 months. More notable is that in a majority of patients, various synkinetic movements completely disappeared after 2-3 sessions of trimonthly Botox injections.

A more specific synkinesis, crocodile tears syndrome (hyperlacrimation upon eating), has been shown to respond exceedingly well to Botox injection. Botox is injected directly into the lacrimal gland and has shown to reduce hyperlacrimation within 24–48 hours. The procedure was shown to be simple and safe with very little chance of side-effects (although on rare occasions ptosis can occur due to botulinum toxin diffusion). Furthermore, reduction in hyper-lacrimation was shown to last longer than the expected 3 months (about 12 months).

Since Botox can mimic facial paralysis, an optimized dose has been determined that reduces involuntary synkinesis of the muscle while not affecting muscle tone.

Researchers now are testing different possibilities for treating dysmetria and ataxia. One opportunity for treatment is called rehearsal by eye movement. It is believed that visually guided movements require both lower- and higher-order visual functioning by first identifying a target location and then moving to acquire what is sought after. In one study, researchers used visually guided stepping which is parallel to visually guided arm movements to test this treatment. The patients suffered from saccadic dysmetria which in turn caused them to overshoot their movements 3. The patients first walked normally and were then told to twice review the area that was to be walked through 3. After rehearsal with eye movements, the patients improved their motor performance. Researchers believe that prior rehearsal with the eyes might be enough for a patient who suffers from motor dysmetria as a result of saccadic dysmetria to complete a motor task with enhanced spatial awareness.

Research has also been done for those patients who suffer from MS. Deep brain stimulation (DBS) remains a viable possibility for some MS patients though the long-term effects of this treatment are currently under review. The subjects who have undergone this treatment had no major relapse for six months and disabling motor function problems. Most subjects benefited from the implantation of the electrodes and some reported that their movement disorder was gone after surgery. However, these results are limiting at this time because of the small range of subjects who were used for the experiment and it is unknown whether this is a viable option for all MS patients who suffer from motor control problems.

Practical surgical procedures used for treating synkinesis are neurolysis and selective myectomy. Neurolysis has been shown to be effective in relieving synkinesis but only temporarily and unfortunately symptoms return much worse than originally. Selective myectomy, in which a synkinetic muscle is selectively resected, is a much more effective technique that can provide permanent relief and results in a low recurrence rate; unfortunately, it also has many post-operative complications that can accompany including edema, hematoma, and ecchymosis. Therefore, surgical procedures are very minimally used by doctors and are used only as last-resort options for patients who do not respond well to non-invasive treatments.

Initially, the condition is treated with physical therapies, such as stretching to release tightness, strengthening exercises to improve muscular balance, and handling to stimulate symmetry. A TOT collar is sometimes applied. Early initiation of treatment is very important for full recovery and to decrease chance of relapse.

Surgical release involves the two heads of the sternocleidomastoid muscle being dissected free. This surgery can be minimally invasive and done laparoscopically. Usually surgery is performed on those who are over 12 months old. The surgery is for those who do not respond to physical therapy or botulinum toxin injection or have a very fibrotic sternocleidomastoid muscle. After surgery the child will be required to wear a soft neck collar (also called as Callot's cast). There will be an intense physiotherapy program for 3–4 months as well as strengthening exercises for the neck muscles.

Other treatments include:

- Rest and analgesics for acute cases

- Diazepam or other muscle relaxants

- Botulinum toxin

- Encouraging active movements for children 6–8 months of age

- Ultrasound diathermy

If an optokinetic drum is available, rotate the drum in front of the patient. Ask the patient to look at the drum as you rotate it slowly. If an optokinetic drum is not available, move a strip of paper with alternating 2-inch black and white strips across the patient's visual field. Pass it in front of the patient's eye at reading distance while instructing the patient to look at it as it rapidly moves by. With normal vision, a nystagmus develops in both adults and infants. The nystagmus consists of initial slow phases in the direction of the stimulus (smooth pursuits), followed by fast, corrective phases (saccade). Presence of nystagmus indicates an intact visual pathway.

Another effective method is to hold a mirror in front of the patient and slowly rotate the mirror to either side of the patient. The patient with an intact visual pathway will maintain eye contact with herself or himself. This compelling optokinetic stimulus forces reflex slow eye movements.

OKN can be used as a crude assessment of the visual system, particularly in infants. When factitious blindness or malingering is suspected, check for optokinetic nystagmus to determine whether there is an intact visual pathway.
