Retinitis Pigmentosa (RP) is one of the diseases associated with our eyes. It starts in the “retina,” the light-sensitive thin layer of tissue in the back part of our eye. Conditions of the eyes are both inherited and acquired, but with retinitis pigmentosa, it is an inherited degenerative disease. Retinitis pigmentosa is a group of eye diseases; a rare condition wherein the loss and breakdowns of cells in the retina occur, and because of this, the eyes progressively degenerate which results in blindness. This condition still doesn’t have a cure, but some methods can slow the eyes’ vision loss.
The retina has two types of cells: rods and cones. Both cells are photoreceptors in the retina. The rods function in a nightlight or lower light while cones cells are visual photoreceptors. Rods are found in the outer sides of the retina and aid peripheral vision. Cones function in bright lights or daylight. They’re located in the center of the retina, and they help your eyes see colors and details. In most cases, the rods degenerate first and not cones, and because of that, you lose your peripheral vision first, and when the disease reaches your cones, you’ll lose your vision and your ability to see colors.
