Glaucoma is a cluster of eye conditions generally sharing prevalent characteristics like high IOP or intraocular pressure or eye pressure that has a damaging effect on the optic nerve and leads to eventual vision failure. However, glaucoma could develop even in the absence of any rise in eye pressure due to a condition called as Normal pressure or low pressure glaucoma or at times called as low-tension glaucoma. Several specialists are of the viewpoint that individuals who develop low pressure glaucoma possess unusual sensitiveness in their optic nerves. However, there are several unidentified factors that could be major contributors to this eye condition. Low pressure glaucoma also known as normal tension glaucoma (NTG) is a type of glaucoma wherein harm to the optic nerve arises even when  [...] 

Chronic glaucoma or POAG or primary open angle glaucoma is mostly known as the ‘the sly robber of eyesight’ as one has no caveat signs, no pains or clues about something not right. Nearly half the U.S. populace having chronic glaucoma are unaware of its presence. An imbalanced production and draining of aqueous humor (clear fluid) which packs the anterior chamber of the eye causes open angle glaucoma. This could develop due to ciliary body manufacturing excessive aqueous or due to blockage in the drainage channels or trabecular meshwork present in the eye’s anterior chamber leading to elevation in IOP (internal eye pressure). Due to IOP increasing, resultant pressure would push further against the optic nerve’s fibres that convey images to the brain. A surge in pressure decreases blood  [...]
