In an individual with a retinal detachment the retina becomes separated from its underlying support tissue. In the area of the detachment vision is lost (right), the area of vision loss depends on the size of the initial detachment and can grow rapidly if untreated. Patients describe this effect like the closing of a shutter. The appearance of "floaters" is also common, which patients perceive as glob or strand floating in their field of vision. Based on the degree and or location of the retinal detachment some individuals experience blurred vision in their remaining visual field unaffected by the detachment.
