Retina
The retina, located at the back of your eye, is responsible for converting light into electrical signals that your brain interprets as vision. Unfortunately, the retina is susceptible to a variety of diseases. These retinal diseases can damage the retina in different ways, leading to vision problems.
Here’s a breakdown of some common retinal diseases:
Age-related macular degeneration (AMD): A major cause of vision loss in older adults. There are two main types: dry AMD (damages light-sensitive cells) and wet AMD (causes abnormal blood vessel growth).
Diabetic retinopathy: A complication of diabetes that damages blood vessels in the retina. A leading cause of vision loss in working-age adults.
Retinal detachment: A medical emergency where the retina separates from its underlying layer. Requires prompt treatment to prevent vision loss or blindness.
Macular hole: A small opening in the macula (central area of retina responsible for sharp vision). Can cause sudden and severe vision loss.
Retinitis pigmentosa: A group of inherited diseases that gradually damage light-sensitive cells in the retina. Leads to vision loss and night blindness.
These are just a few examples, and retinal diseases can have various causes, including genetics, aging, underlying health conditions (like diabetes), and injuries. Symptoms can include:
- Decreased vision
- Blurry vision
- Difficulty seeing at night (night blindness)
- Changes in color vision
- Seeing flashes of light or light spots
- Blind spots or dark areas in your vision
- Distorted vision (straight lines appearing wavy)
Early detection and treatment are crucial for managing retinal diseases and preserving vision. If you experience any vision problems, consult an eye doctor for a comprehensive evaluation.
