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]
Aqueous cells without the signs of uveitis, elevated intraocular pressure and rhegmatogenous retinal detachment with tears around the ora serrata are the main signs of Schwartz–Matsuo syndrome. [1] Intra ocular pressure can be as high as 60–70 mm Hg and is responsive to aqueous suppressants. [ 3 ]
Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication. Intraocular pressure laws follow fundamentally from physics. Any kinds of intraocular surgery should be done by considering the intraocular pressure fluctuation.
A study with 1636 persons aged 40-80 who had an intraocular pressure above 24 mmHg in at least one eye but no indications of eye damages showed that after five years 9.5% of the untreated participants and 4.4% of the treated participants had developed glaucomatous symptoms, meaning that only about one in ten untreated people with elevated ...
Phacomorphic glaucoma is an eye disease that can occur due to a neglected advanced cataract.In this, the mature cataractous lens cause secondary angle closure glaucoma.The presence of an asymmetric mature cataractous lens, shallow or closed anterior chamber angle, raised intraocular pressure (IOP) and other typical signs and symptoms of angle-closure glaucoma in the eye may lead to a diagnosis ...
Posner–Schlossman syndrome (PSS) also known as glaucomatocyclitic crisis (GCC) is a rare acute ocular condition with unilateral attacks of mild granulomatous anterior uveitis and elevated intraocular pressure. It is sometimes considered as a secondary inflammatory glaucoma.
Uveitis–glaucoma–hyphaema (UGH) syndrome, also known as Ellingson syndrome, is a complication of cataract surgery, caused by intraocular lens subluxation or dislocation. The chafing of mispositioned intraocular lens over iris , ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema .
If glaucomatous damage occurs despite normal eye pressure or if glaucomatous damage is progressive despite normalized intraocular pressure, frequently Flammer syndrome is the cause. In these eyes, an elevated pressure in the retinal veins has been observed. [10]
