Babies suffering from PTU may exhibit normal or slightly jerky side-to-side eye movement, nausea, irritability, frequent sleep, developmental and language delays, vertigo and loss of muscle tone. [citation needed] The condition is generally regarded as having a benign outcome, in the sense that it improves, rather than worsens over time.
The symptoms of vestibulocerebellar syndrome vary among patients but are typically a unique combination of ocular abnormalities including nystagmus, poor or absent smooth pursuit (ability of the eyes to follow a moving object), strabismus (misalignment of the eyes), diplopia (double vision), oscillopsia (the sensation that stationary objects in the visual field are oscillating) and abnormal ...
Joubert syndrome is a rare autosomal recessive genetic disorder that affects the cerebellum, an area of the brain that controls balance and coordination.. Joubert syndrome is one of the many genetic syndromes associated with syndromic retinitis pigmentosa. [4]
Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth while swallowing, chewing, resting, or speaking. Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites.
Parinaud's syndrome is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by: Paralysis of upwards gaze: Downward gaze is usually preserved. This vertical palsy is supranuclear, so doll's head maneuver should elevate the eyes, but eventually all upward gaze mechanisms fail. In the extreme form, conjugate down gaze ...
Nystagmus as seen in a case of ocular albinism. The cause of 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 when a person has been spinning in circles) or by some drugs (alcohol, lidocaine, and other central nervous system depressants, inhalant ...
Two images of the same child. The top image shows the left eye slightly cross-eyed. This is fixed in the bottom picture by stretching the extra skin around the eye. A deviated gaze is an abnormal movement of the eyes. It is often found as a symptom for subdural hematoma or some people may have it from birth.
A lesion, which is an abnormality in tissue due to injury or disease, can disrupt the transmission of signals from the brain to the eye. Almost all conjugate gaze palsies originate from a lesion somewhere in the brain stem, usually the midbrain, or pons.
