Tractional- when the scar tissues grow on the retina’s surface, this type of detachment occurs.It can be caused due to injury to the eye, age-related macular degeneration, inflammatory disorders or tumors. Exudative- the condition where fluid accumulates behind the retina without causing holes or tears are called exudative.If left untreated, the vitreous passes on to the space behind retina, resulting in the detachment of retina. As the vitreous peels off the retina, it might tug on the retina forcefully causing retinal tear. This condition is known as PVD (posterior vitreous detachment). Usually, the vitreous moves away from the surface of the retina. The gel-like material present inside the eyes (called as vitreous) changes consistency and even shrinks becoming more of a liquid, due to ageing. This severely affects the vision.Rhegmatogenous detachment usually occurs due to ageing. This pulls away the retina from the underlying tissues and the areas from where the retina detaches stops functioning due to the loss of blood supply. The hole formed enables fluid to pass through and get collected near the retina. Rhegmatogenous- it is one of the most common type of retinal detachment which occurs due to a tear or hole in the retina.The three main causes of detached retina are. Sudden appearance of floaters or tiny specks which seem to be floating before the eyes.Photopsia, which is flashes of light occurring in one or both the eyes especially when looking to the side.Gradual reduction in peripheral (side) vision.
