The eye is a very complex functional and anatomic organ. The retina is a thin, delicate and transparent sheet of tissue that lines the inside of the back of the eye. Directly in front of the retina is also a cavity that contains a gel called vitreous. The structure responsible for the bulk and shape of our eye is Vitreous part. It is a jelly-like body that fills the posterior chamber of the eye, giving the eyeball its round shape and keeping the retina in place against the back of the eye. It is made up of millions of tiny collagen fibrils along with ground substance mucopolysaccharides such as hyaluronic acid, which form a gel. The vitreous is mostly water, which makes up 98% of it. The collagen strands connect to the superficial layers of the retina especially around the macula, the retinal vessels or sites at the retinal periphery. Posterior vitreous detachment (PVD) , also known as hyaloid detachment, occurs when the retinal layer and vitreous body/posterior hya...
