uvea
[ˈjuːviə ]
Definition
anatomy, eye
The uvea is the middle layer of the eye, situated between the outer sclera and the inner retina. It consists of three parts: the iris, the ciliary body, and the choroid. The uvea is crucial for providing nutrients to the eye and plays a significant role in the regulation of light entering the eye. Inflammation of the uvea is known as uveitis, which can lead to vision problems if left untreated.
Synonyms
Examples of usage
- The uvea helps in filtering light.
- Uveitis can cause severe eye pain.
- The doctor examined the uvea for signs of inflammation.

Interesting Facts
Anatomy
- The uvea has three parts: the iris (the colored part), the ciliary body (which helps focus the lens), and the choroid (which nourishes the retina).
- It plays a crucial role in regulating the amount of light entering the eye by controlling the size of the pupil.
Health
- Uveitis is an inflammatory condition that affects this layer, which can lead to vision problems if not treated.
- Certain autoimmune diseases can also cause issues in this part of the eye, highlighting the importance of regular eye check-ups.
Science
- The uvea is vital for the eye's overall health, as it contains blood vessels that provide oxygen and nutrients.
- Research continues to explore how the uvea interacts with other parts of the eye and the impact of diseases on its function.
Cultural References
- The uvea’s role in vision is often used as a metaphor in literature, symbolizing clarity and perception.
- In some cultures, the health of the eyes, including the uvea, is seen as reflective of overall health and well-being.
Origin of 'uvea'
Main points about word origin
- The term 'uvea' comes from Latin, meaning 'grape,' because the dark middle layer of the eye looks like a bunch of grapes.
- In English, the word has been used since the 1400s, connecting language and biology.
The term 'uvea' is derived from the Latin word 'uvea', which means 'grape'. This name was chosen because the uvea resembles the structure of a grape, being a soft, vascular layer of tissue. The anatomical understanding of the uvea has evolved over centuries, with significant contributions from ophthalmologists and anatomists. In the 19th century, advancements in microscopy allowed for a better understanding of the uvea's structure and function. Today, the uvea is recognized not just for its anatomical importance but also for its involvement in several ocular diseases, making it a focal point of study in modern ophthalmology.
