In the past the vitreous body was removed from your eye and replaced by silicone oil. This filling has now been topped up or changed.

The vitreous body in the eye consists of a transparent, gel-type fluid. It is surrounded by a thin membrane and fills the entire rear part of the eye. This is how it gives the eye its shape. The previous surgery involved using a special tool to cut out part of your vitreous body and aspirate it. A fine layer of connective tissue was then removed from your eye. Various conditions can involve the formation of these layers of connective tissue, and they can impair one’s vision.

These layers of connective tissue had pulled on your retina and partially detached it. The retina is a layer inside the eye. It contains a lot of sensory cells that can perceive light. There are sensory cells for colors and sensory cells for light and dark. The sensory cells pass the information on to the nerve cells in the optic nerve.
