Retinal detachment is a medical condition that occurs when the retina, the thin membrane at the back of the eye, becomes separated from its underlying support tissue. There are several other synonyms used to refer to this condition, such as macular hole, vitreous detachment, and retinal tear. Macular hole refers to a puncture or tear in the macula, which is the part of the retina that is responsible for sharp central vision. Vitreous detachment occurs when the vitreous, the jelly-like substance that fills the eye, pulls away from the retina. Retinal tear is a condition where the retina is torn, but has not yet detached from its support tissue. All these conditions require immediate medical attention to avoid the risk of vision loss.
