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]
Hypertensive crisis; Other names: Malignant hypertension, accelerated hypertension: A systolic hypertensive crisis as measured on a home automated arm blood pressure monitor, showing an extremely elevated systolic blood pressure of 227, a mildly elevated diastolic blood pressure of 93 and a very fast tachycardic heart rate of 162 beats per minute.
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. [1] [3]
Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.

This can mean that systolic pressure is abnormally high, but diastolic pressure may be normal or low, a condition termed isolated systolic hypertension. [80] The high pulse pressure in elderly people with hypertension or isolated systolic hypertension is explained by increased arterial stiffness , which typically accompanies aging and may be ...
A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. [2] If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. [3] The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.
Sometimes you can have systolic or diastolic hypertension, where one number is normal, and the other is really high, and in that situation it’s called isolated systolic hypertension or isolated diastolic hypertension. Having high blood pressure is a serious problem for the blood vessels because it causes wear and tear on the endothelial cells ...
Prehypertension, also known as high normal blood pressure and borderline hypertensive (BH), [1] is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension (high blood pressure).
