@doctor.asky: Retinal detachment begins from a small tear. Retinal detachment often begins with a tiny tear in the retina, which is the thin light sensing tissue at the back of the eye. This tear usually forms when the gel inside the eye, called the vitreous, pulls on the retina as it naturally shrinks with age. When the pull becomes strong enough the retina can open slightly, creating a small break that allows fluid to slip underneath it. Once fluid begins to pass through the tear it slowly lifts the retina away from the tissue that supplies it with oxygen and nutrients. At first this separation is very small, so people may only notice flashes of light, sudden floaters, or a shadow appearing at the edge of their vision. Even though the tear itself is tiny the fluid can continue to spread and push the retina further out of place. If the detachment continues to grow the retina loses more of its support and vision becomes increasingly affected. This process is painless but it is considered an emergency because the longer the retina stays detached the higher the chance of permanent vision loss. Quick treatment can seal the tear and reattach the retina, which helps protect vision before the damage becomes severe.
