Retinal detachment is the detached retina from supporting tissue, if not treated, and then entire retina will be detached causing vision loss or blindness. It is a medical emergency.
Detachment of Retinal
Retina - is a thin light sensitive tissue layer on the eye back. The eye lens focuses light on the retina; it converts focused image into neural impulses and transmit it to the brain via the optic nerves.
The most common type of retinal detachment develops when tear/hole forms in the retina, which permits vitreous fluid from the middle of the eye to enter under the retina. This causes the retina layer to detach, so it no longer works normally and causes vision loss in the affected area.
The risk of retinal detachment is around 5 in 100,000 per year. Retinal detachment is more common among middle-aged or elderly population with rates of around 20 in 100,000 per year.
