Ocular dysmetria
Ocular Dysmetria
Ocular dysmetria (/ɒˈkjʊlər dɪsˈmiːtrɪə/; from Greek dys- meaning "bad", and metria meaning "measure") is a condition characterized by the inability of the eyes to stop their movement at the desired point, leading to overshooting or undershooting of the target. This condition is often associated with cerebellar dysfunction and is commonly seen in diseases such as Multiple Sclerosis and Friedreich's Ataxia.
Symptoms
The primary symptom of ocular dysmetria is the inability to control the movement of the eyes accurately. This can result in the eyes overshooting or undershooting their intended target. Other symptoms may include nystagmus, a condition characterized by involuntary eye movement, and diplopia, or double vision.
Causes
Ocular dysmetria is often caused by damage to the cerebellum, the part of the brain that controls fine motor skills, including eye movements. This damage can be due to a variety of conditions, including Multiple Sclerosis, Friedreich's Ataxia, stroke, or brain tumor.
Diagnosis
Diagnosis of ocular dysmetria is typically made through a neurological examination. The doctor may ask the patient to follow a target with their eyes without moving their head. If the eyes overshoot or undershoot the target, this may indicate ocular dysmetria. Further tests, such as MRI or CT scan, may be used to identify any damage to the cerebellum.
Treatment
Treatment for ocular dysmetria primarily involves addressing the underlying cause. This may involve medication, surgery, or physical therapy, depending on the cause. In some cases, vision therapy may be recommended to help improve eye coordination and control.
