The normal vitreous body is a special mucous gel-like tissue in the form of a transparent gel with no blood vessels or nerve tissue of its own. Its metabolism is extremely slow and its nutrition and metabolism is accomplished by diffusion through neighboring tissues. Vitreous opacity is the appearance of an opaque body within the vitreous. It is not a separate eye disease, but one of the common clinical signs in ophthalmology. Some vitreous turbidities may disappear on their own or become smaller over time. The use of medications such as amiodarone and lecithin-complexed iodine may help to accelerate absorption, and severe vitreous turbidities can be treated with minimally invasive vitrectomy. Laser treatment is effective for some vitreous turbidities. What are the causes of vitreous opacities? Vitreous turbidity is classified as degenerative, inflammatory, hemorrhagic, traumatic, or systemic disease. The most common cause is vitreous degeneration in the elderly and myopic patients. Other causes also include hemorrhage from the retina or uvea into the vitreous, embryonic cells or tissue left in the vitreous from birth, ocular trauma, retained foreign bodies in the eye, parasites and tumors.
