What is retinitis pigmentosa?
Retinitis pigmentosa is the name of a group of eye diseases that are passed down in families. All of them affect the retina. The retina is the nerve layer that lines the back of the eye. It is sensitive to light. All of the diseases cause a slow but sure decline in eyesight.
What causes retinitis pigmentosa?
Retinitis pigmentosa affects the ability of cells in the retina to sense light. Over time, the cells break down and die. The problem with the retina can take place in any of the following:
- Rod cells
- Cone cells
- The link between the cells that make up the retina
What are the symptoms of retinitis pigmentosa?
The symptoms of retinitis pigmentosa often begin in childhood or the teen years. But symptoms can be a bit different for each person. Some people with the disease have a slow, very progressive loss of eyesight. Others lose their eyesight much more quickly and severely. Common symptoms may include:
- Hard time seeing in poor lighting or in the dark
- A reduced ability to see either central vision or side (peripheral) vision
- Hard time reading print
- Hard time figuring out detailed images
- Hard time with stumbling or tripping over objects not seen
The symptoms of the condition may look like other eye diseases. Talk with your eye healthcare provider for a diagnosis.
