Detachment of the vitreous humor occurs in the presence of dystrophic changes. There are anterior and posterior detachment of the vitreous.

Anterior vitreous detachment is often observed in the elderly, less often - in trauma and inflammatory processes in the vascular tract. It can be detected by biomicroscopy. In this case, the space between the lens and the vitreous appears to be optically empty.

The posterior detachment of the vitreous often occurs with myopia and often precedes the retinal detachment. The back detachment can have different height, shape and extent, be complete or partial. The most frequent option is a complete posterior vitreous detachment, which is detected throughout the posterior pole of the eye with a more or less pronounced displacement toward the center. In these cases, the vitreous body breaks away from the optic nerve disk and, with biomicroscopy and ophthalmoscopy, a gray oval ring is revealed in front of the optic nerve disc, while the subvitreal space is filled with liquid. A partial detachment occurs less frequently and either it is temporary or gradually increases and becomes full.

The most severe manifestation of the dystrophic process in the vitreous body is its wrinkling (a decrease in volume), often detected in chronic inflammatory processes in the retina and choroid, after penetrating wounds of the eye, as well as traumatic intraocular operations accompanied by loss of vitreous body.
