Glaucoma Blinding Disorders and Optic Neuropathy Biology Essay
Any intrinsic or extrinsic compression anywhere along the optic nerve can cause compressive optic neuropathy CON. In addition to damage from compression, damage to the optic nerve can occur as a result of a condition. There is some evidence that high myopia is associated with the development of glaucoma or glaucoma-like optic neuropathy, and that both share many features. These similarities often pose a diagnostic challenge that will impact the future management of glaucoma suspects with high myopia. In this review, we summarize that glaucoma is a progressive, neurodegenerative optic neuropathy in which currently available therapies cannot always prevent or reverse vision loss. Stem cell transplantation may offer a promising new avenue for treating many currently incurable degenerative diseases, including glaucoma. This article takes a closer look at Glaucoma, an eye condition in which the optic nerve is damaged. This affects the field of vision, leading to 'blind spots'. Glaucoma is often caused by increased intraocular pressure in the eye, which can be treated with eye drops. The most common form is called open-angle glaucoma. Glaucoma, a leading cause of blindness in the world, can be challenging to diagnose because symptoms often appear late in the disease, and challenging to treat because of the irreversible loss of retinal neurons. The term covers a heterogeneous group of diseases characterized by altered biomechanics. It happens gradually, with the eye not draining fluid as well as it should as a blocked drain. As a result, eye pressure builds up and the optic nerve begins to damage. This type of glaucoma is painless. Optic atrophy is the term used when optic nerve pallor occurs and is considered an end-stage marker of non-glaucoma optic nerve disease. It takes weeks for optic atrophy to develop after the initial injury. 1. Furthermore, it can be divided into primary or secondary optic atrophy. Due to the increasing prevalence of high myopia throughout the world, structural and functional damage to the optic nerve in high myopia has recently attracted much attention. There is evidence that high myopia is associated with the development of glaucoma-like or glaucoma-like optic neuropathy, and that both common glaucoma, a leading cause of irreversible blindness worldwide, is a spectrum of neurodegenerative diseases characterized by the gradual deterioration of retinal blindness. ganglion cell RGCs and optic neuropathy. With the complex etiology, the main risk factors for glaucoma include increased intraocular pressure (IOP), advanced age, ethnicity. Optic neuropathies are characterized by the degeneration of the optic nerves and represent a significant individual and societal burden. In particular, Leber's hereditary optic neuropathy LHON is a devastating eye disease caused by mitochondrial gene mutations that impair oxidative phosphorylation and increase oxidative stress, leading to: Our preliminary diagnosis was ischemic optic neuropathy, and the reasons are as follows: in typical glaucoma in a moderate stage, the RNFL defect was relatively large in the affected eye, b the visual field showed an arcuate defect, without sparing the temporal side of the physiological blind spot, c the central, 1. The optic nerve will be edematous in cases of optic neuritis . Most likely, over the years you have been in your...,
