Glaucoma is a group of progressive optic neuropathy which is characterized by the degradation of ganglion cells present in the retina. The loss of the retinal ganglion is associated with intraocular pressure (IOP), an elevated IOP due to an imbalance in the production and drainage of aqueous humor that might lead to structural changes in the lamina cribrosa (a mesh-like structure at the optic nerve head that surrounds and supports the retinal ganglion cell axons as they form the optic nerve). This further causes impairment in the signal transmission by the axons through the optic nerve fibers leading to progressive damage in the visual field. Apart from increased IOP,...
