The optic nerve is like a telephone cable that connects the eye and the brain. Light is focused in the through the clear cornea and lens onto the retina. This amazing living tissue changes the light energy into chemical and electrical signals that pass along the optic nerve to the brain. Any disease that causes damage to the optic nerve leads to loss of vision and complete blindness in some cases.
The problem with the muscle responsible for moving the eye out to the ear.
Causes double vision straight ahead, worse when trying to look to the side. Common in the elderly who have high blood pressure and diabetes and in younger patients with neurologic diseases such as multiple sclerosis. Usually, resolves without treatment in 6-8 weeks.
Related to but not caused by an autoimmune Thyroid disease called Graves disease. Patients with TED present with bulging of the eye, double vision, droopy lids, and dry eyes. It usually affects the eyes asymmetrically so one may notice one eye looks bigger than the other.
It is common to have intermittent unequal pupils such as during a headache or during stressful times. Pupils that return to normal are not an emergency.
Headache is usually not a sign of severe neurologic disease. If it is unremitting, progressive and associated with other neurologic signs such as weakness, numbness, difficulty walking or talking this could be a sign of a stroke, tumor, or of increased intracranial pressure.
Papilledema is a manifestation of increased intracranial pressure. The optic nerves become swollen due to the elevation of intracranial pressure. Diagnosed by a dilated eye examination and visual field and ocular coherence tomography (OCT). Moderate-to-severe cases are easily detected. Mild papilledema may be more difficult to detect due to a wide range of variability in the appearance of the optic nerve.
Variant 1, in which the patient presents with headache, fatigue, weight loss, pain on chewing and scalp tenderness. Diagnosed by elevated lab parameters; ESR, CRP, IL6. A biopsy of the superficial temporal artery is performed to confirm the diagnosis. This is a true neuro-ophthalmologic emergency with serious risks both visually and systemically as the major arteries of the body may be affected. Emergent treatment with oral or intravenous steroids is initiated and usually maintained for over one year.
