|The retina is the innermost layer of the three layers that make up the eye and is responsible for transforming light stimuli into electrical stimulation to be carried by the optic nerve to different parts of the brain. This is how the images we see are formed. Unlike what occurs with other structures of the eye such as the cornea or lens, so far science has not found a way to replace the retina tissue.Therefore, damage at this level can result in irreversible loss of vision.|
The most common causes of injury in the retina are diabetes mellitus and the not controlled hypertension. It is one type of ocular trauma and requires immediate attention by muscle degeneration that particularly affects people over 65 years of age. The vitreous is a gelatinous and transparent tissue under normal conditions, which fills the center of the eyeball.
It’s the vascular tunic of the eye and is responsible among other functions, for its nutrition. It’s comprised of three structures: the iris, ciliary body and choroid.
