The light-sensitive tissue at the back of our eyes is called ‘retina’. In some people, the tissues of the retina start to weaken or thin and retinal breaks begin to develop in areas of thinning. Thus, a retinal break is a tiny hole(without any traction or pressure points on the retina) or tear(which develops due to any traction or pressure on the retina) in the retina. It can occur in the periphery of the retina. Sometimes, the vitreous gel may also tear the retina by pulling it away.
