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. It is ...
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 ...
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 ]
People with such condition begin to rapidly lose their eyesight. Sometimes, the disease appears very rapidly, especially after cataract surgery procedures. Toxic glaucoma is open-angle glaucoma with an unexplained significant rise of intraocular pressure following unknown pathogenesis. Intraocular pressure can sometimes reach 80 mmHg (11 kPa).
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 of phacomorphic glaucoma. Cataract surgery after initial IOP control with medication is the only treatment.
Risk factors for secondary glaucoma include uveitis, [1] cataract surgery [5] and also intraocular tumours. [5] Common treatments are designed according to the type (open-angle or angle-closure) and the underlying causative condition, in addition to the consequent rise in IOP. These include drug therapy, the use of miotics, surgery or laser ...
Intraocular pressure laws follow fundamentally from physics. Any kinds of intraocular surgery should be done by considering the intraocular pressure fluctuation. Sudden increase of intraocular pressure can lead to intraocular micro barotrauma and cause ischemic effects and mechanical stress to retinal nerve fiber layer. Sudden intraocular ...
The blockage leads to greater-than-normal elevated intraocular pressure [2] which, in turn, can damage the optic nerve. [7] The eye produces a clear fluid called the aqueous humor which subsequently drains such that there is a constant level of safe pressure within the eye, but glaucoma can result if this normal outflow of fluid is blocked.
