Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. Elevated intraocular pressure is an important risk factor and symptom of glaucoma.
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
The changes in hypertensive retinopathy result from damage and adaptive changes in the arterial and arteriolar circulation in response to the high blood pressure. Diagnosis. Fundoscopy and patients history. Differential Diagnoses. Several other diseases can result in retinopathy that can be confused with hypertensive retinopathy.
The high blood pressure eventually leads to heart failure, strokes, heart attacks, blindness, kidney failure, loss of libido and poor circulation of blood in the legs. When the blood supply to the feet is compromised, the chances of infections and amputations also increases. All diabetics should know that even mild elevations in blood pressure ...
Hypertension; Pre-eclampsia (toxemia of pregnancy) Occlusive vascular disease (sudden) Emboli and thrombi; Central retinal artery occlusion; Cardiac myxoma; Cranial arteritis; Sickle cell attack; Occlusive vascular disease (slow, progressive) Carotid artery disease; Arterial spasm (TIA) Diabetes mellitus; Collagen diseases; Venous occlusive ...
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 ...
Hypertension and the brain. Hypertension is a condition characterized by an elevated blood pressure in which the long term consequences include cardiovascular disease, kidney disease, adrenal gland tumors, vision impairment, memory loss, metabolic syndrome, stroke and dementia. [1] It affects nearly 1 in 2 Americans and remains as a ...
Other symptoms may include increased irritability, vomiting, diplopia, seizures, twitching and myoclonus of the limbs. Alterations in vision (vision blurring, hemivisual field defects, color blindness, cortical blindness) are common. They occur in 4 out of 11 cases (Jellinek et al. 1964).
Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication .
Specialty. Cardiology. A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys).
