Vision loss in patients with vitreous detachment is usually not rapid and in most cases does not affect the patient’s vision.
Vitreous detachment is mostly referred to as posterior vitreous detachment, which refers to a separation between the vitreous body that fills the interior of the eye and the wall of the eye, and the separated cavity is filled with fluid such as aqueous humor. Typically, patients with posterior vitreous detachment may experience symptoms such as a flashing sensation and watery vision, but it does not usually affect vision.
A small number of patients may pull and tear the retina when posterior vitreous detachment occurs, causing foraminal retinal detachment, at which time the patient may experience vision loss, but the cause of vision loss is not posterior vitreous detachment, but due to retinal detachment.
It is recommended that patients with postvitreous detachment who have vision loss should be seen in a hospital in a timely manner to have their condition evaluated and treated in accordance with the doctor’s instructions.
