Index: Age related changes in refractive index (cortical sclerosis) can cause hypermetropia. Another cause of index hypermetropia is diabetes. [2] Occasionally, mild hypermetropic shift may be seen in association with cortical or subcapsular cataract also. [12] Positional: Positional hypermetropia occur due to posterior dislocation of Lens or ...
This astronaut had the most pronounced optic-disc edema of all astronauts reported to date, but had no choroidal folds, globe flattening or hyperopic shift. At 10 days post landing, an MRI of the brain and eyes was normal, but there appeared to be a mild increase in CSF signal around the right optic nerve. [5]

These drugs increase the permeability of the blood–brain barrier temporarily by increasing the osmotic pressure in the blood which loosens the tight junctions between the endothelial cells. By loosening the tight junctions normal injection of drugs through an [IV] can take place and be effective to enter the brain. [8]
“In addition, we know these vessels change in response to a variety of systemic vasculopathic conditions including hyperlipidemia, hypertension, diabetes, and inflammatory disorders that can all ...
Subtle changes in brain activity in the presence of both amyloid-beta and tau proteins may point to Alzheimer's disease, long before symptoms appear, a new study indicates.
Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
