The choroid is a complex vascular layer in the eye, situated between the sclera and retina. It consists of blood vessels, melanocytes, and fibroblasts.
Key characteristics:
- Blood supply: The choroid is richly vascularized, supplying the retina with oxygen and nutrients.
- Location: It’s situated between the sclera (outer layer) and retina (inner layer).
- Melanin content: The choroid contains melanin, which helps absorb excess light.
Functions:
- Nutrient supply: Provides the retina with essential nutrients and oxygen.
- Waste removal: Helps remove waste products from the retina.
- Light absorption: The melanin in the choroid absorbs excess light, reducing scatter and improving vision.
The choroid plays a vital role in maintaining the health and function of the retina, supporting clear vision and overall eye health.
