Seek professional care if you experience any of the following symptoms
Generally, Disorders of eye movement can be related to:
Tolosa-Hunt Syndrome is a rare condition characterized by severe headaches behind the eyes, decreased and painful eye movements typically in just one eye. The exact cause is unknown, but it may be related to inflammation in certain areas behind the eye.
MELAS is a rare genetic disorder that starts in childhood and mainly affects the nervous system and muscles. The disorder is transmitted through the affected person's mother. Typical MELAS symptoms include weak muscles, sudden ("stroke-like") neurological symptoms such as paralysis of the right or left side of the body, blindness, or numbness, in addition to seizures and migraine-like headaches. People who have MELAS are also typically short in size, and have difficulty hearing.
Sometimes, Disorders of eye movement may be related to these serious diseases:
An injury where the bones around the eye are fractured, usually caused by a severe impact to the front of the eye, such as a golf ball.

Q.
One Pupil Larger Than the Other? When This Is a Medical Emergency
A.
Unequal pupils can be benign, but a sudden change is an emergency if it comes with severe headache, head injury, confusion, vision loss or double vision, drooping eyelid, weakness or numbness, slurred speech, seizures, or neck stiffness; these can signal stroke, aneurysm, brain bleeding, high intracranial pressure, or acute angle-closure glaucoma and need immediate ER care. There are several factors to consider, including long-standing harmless anisocoria, medication effects, migraine, and nerve problems like third nerve palsy or Horner’s syndrome, which change the next steps for care; see below for specific red flags, what to do right now, and when monitoring is reasonable.

Q.
Is Your Eye Drifting? Why Your Lazy Eye is Failing & Medically Approved Next Steps
A.
There are several factors to consider; a drifting or worsening lazy eye is most often related to muscle imbalance, uncorrected vision differences, or untreated childhood amblyopia, and fatigue can make it more noticeable, while a sudden new drift or double vision in adults can point to nerve or neurologic issues that need urgent care. Medically approved next steps include a comprehensive eye exam, updated glasses or prisms, vision therapy or selective patching, possible strabismus surgery, and treating underlying conditions, with important nuances that could change your plan explained below.
