Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [ 1][ 2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [ 3][ 4] Elevated intraocular pressure is an important risk ...
Hypertensive encephalopathy ( HE) is general brain dysfunction due to significantly high blood pressure. [ 3] Symptoms may include headache, vomiting, trouble with balance, and confusion. [ 1] Onset is generally sudden. [ 1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye ...
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.
Those who remained diabetes-free for at least 4 years had a 26% lower risk of all-cause mortality and a 40% lower risk of vascular problems. Participants who remained free of diabetes for at least ...
Sulphonamide therapy can cause ciliary body edema, resulting in anterior displacement of the lens, pushing the eye out of focus. [71] Elevation of blood-glucose levels can also cause edema (swelling) of the crystalline lens as a result of sorbitol accumulating in the lens. This edema often causes temporary myopia.
The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
Under some conditions, children and young adults can see ultraviolet down to wavelengths around 310 nm. [ 7 ] [ 8 ] Near-UV radiation is visible to insects, some mammals, and some birds . Birds have a fourth color receptor for ultraviolet rays; this, coupled with eye structures that transmit more UV gives smaller birds "true" UV vision.
Growth hormone therapy refers to the use of growth hormone (GH) as a prescription medication —it is one form of hormone therapy. Growth hormone is a peptide hormone secreted by the pituitary gland that stimulates growth and cell reproduction. In the past, growth hormone was extracted from human pituitary glands.
