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 ...
Flammer syndrome. Flammer syndrome is a described clinical entity comprising a complex of clinical features caused mainly by dysregulation of the blood supply. It was previously known as vascular dysregulation. [ 1] It can manifest in many symptoms, such as cold hands and feet, and is often associated with low blood pressure.
946163-60-6. KEGG. D10840. Bimatoprost/timolol, sold under the brand name Ganfort, is a medication for the treatment of certain conditions involving high pressure in the eyes, specifically open angle glaucoma and ocular hypertension. [ 1][ 3] It is available as eye drops. [ 1][ 3] It was approved for medical use in the European Union in May 2006.
Orthostatic hypotension, also known as postural hypotension, [ 2] is a medical condition wherein a person's blood pressure drops when standing up or sitting down. Primary orthostatic hypotension is also often referred to as neurogenic orthostatic hypotension. [ 3] The drop in blood pressure may be sudden ( vasovagal orthostatic hypotension ...
Blood squirt. Blood squirt ( blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
Strongly modulated blood flow pulse in central and branch arteries can result from hypertension. Microangiography by laser Doppler imaging [3] may reveal altered hemodynamics non-invasively. Mild signs of hypertensive retinopathy can be seen quite frequently in normal people (3–14% of adult individuals aged ≥40 years), even without ...
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.
Ophthalmic artery labeled at upper right. The ophthalmic artery ( OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the cavernous sinus. Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges.
