Glaucoma is a group of eye diseases that can lead to damage of the optic nerve.The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated.
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 ...
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
Sometimes glaucoma may occur without increased intraocular pressure also. [6] Some glaucomas (e.g. open angle glaucoma) cause gradual loss of vision and some others (e.g. angle closure glaucoma) cause sudden loss of vision. [6] It is one of the leading cause of blindness worldwide. [2]
Glaucoma is the leading cause for irreversible blindness globally. [11] Glaucoma usually starts with no symptoms to start losing peripheral vision, and if untreated, it can leads to a complete loss of peripheral vision, which is tunnel vision, and eventually, central vision will be affected leading to complete blindness.
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]
Eye pain and angle-closure glaucoma. Of these side effects, more common ones include nausea, insomnia, tiredness and decreased libido. ... Symptoms like insomnia can be mediated by making a few ...
Posterior synechia also cause glaucoma, but with a different mechanism. In posterior synechia, the iris adheres to the lens, blocking the flow of aqueous humor from the posterior chamber to the anterior chamber. This blocked drainage raises the intraocular pressure.
