VitalCare Nutrition Keto Gummies glaucoma is when the retina and optic nerve are damaged by an increase in the intraocular (within the eye) pressure. This pressure increases because the vitreous humour (the fluid in the eyeball) builds up. Often glaucoma is secondary to other eye problems, such as uveitis. Uveitis is the inflammation of the uvea, which consists of the iris, the ciliary body and the choroid. Uveitis can be a sequel to a wound to the eye, an extension of a corneal ulcer or is a genetic propensity.
