Uvea: meaning, definitions and examples

Etymology

• 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.

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.
