The retina is the innermost layer of the eye and contains light receptors and neurons. This thin layer covers 75% of the inner surface of the eyeball.
The retina includes two types of cells: cone cells, which are responsible for color vision, and rod cells, which are responsible for vision in low light. The macula is a part of the retina located along the optical axis of the eye and plays a role in visual accuracy and sharpness.

• • • After light enters the eye and passes through the lens, it eventually reaches the retina. The retina acts like the film in a camera. When light rays hit the retina, they are converted into neural signals and sent to the brain, where they are interpreted, allowing the eye to see.

• • • • Vitrectomy is a type of eye surgery used to treat certain retinal and vitreous disorders. The vitreous is a transparent, gel-like substance that fills the middle of the eye. Vitrectomy surgery often improves or stabilizes vision.
        During this surgery, the vitreous is removed and typically replaced with a solution.

• • • • The following symptoms usually occur in one eye but may affect both eyes:

        • Flashing lights in the field of vision
        • Blurred vision
        • Wavy or distorted images (sometimes)
        • Blind spots
        • Sudden vision loss
