causes of detached retina in humans
How retinal detachment occurs. Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina. Aging or retinal disorders can cause the retina to thin. Retinal detachment due to a tear in the retina typically develops when the vitreous collapses and tugs on the retina with enough force to create a tear. Fluid inside the vitreous then finds its way through the tear and collects under the retina, peeling it away from the underlying tissues.
