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 ]
Ocular hypertension (OHT) is defined by intraocular pressure being higher than normal, in the absence of optic nerve damage or visual field loss. [13] [14] Ocular hypotension, hypotony, or ocular hypotony, is typically defined as intraocular pressure equal to or less than 5 mmHg.
Ocular hypertension (increased pressure within the eye) is an important risk factor for glaucoma, but only about 10-70% of people - depending on ethnic group - with primary open-angle glaucoma actually have elevated ocular pressure. [24]
PCV is an ocular disease characterised by abnormally shaped vessels in the choroid. [2] It is described as an exudative maculopathy, characterised by multiple recurrent serosanguineous retinal pigment epithelial detachments. [ 3 ]
Ocular hypertension (IOP 30 - 70 mmHg) with open angle of anterior chamber and unilateral mild granulomatous anterior uveitis are hallmark signs of Posner–Schlossman syndrome. [2] On slit-lamp examination, conjunctival injections, epithelial corneal edema, [ 3 ] small to medium-sized fine keratitic precipitates, aqueous cells and flare may ...
Brimonidine is an α 2 agonist medication used to treat open-angle glaucoma, ocular hypertension, and rosacea. [4] [5] In rosacea it improves the redness. [5] It is used as eye drops or applied to the skin. [4] [5] It is also available in the fixed-dose combination medication brimonidine/timolol along with timolol maleate. [6]
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 ...
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
