Vitreous detachment In retinal detachment, the retina separates from the back of the eye. It may follow an eye injury, but usually occurs spontaneously. Typically, only one eye is affected.
Vitreous detachment is when the inside of the eye separates from the retina.
Symptoms of retinal detachment may include flashing lights in the corner of the eye and large numbers of floaters, or a black area in the field of vision.
Retinal detachment requires urgent treatment to prevent blindness.
Treatment may involve laser therapy, cryotherapy (freezing), or surgery and is usually successful, although vision may not always be fully restored.
