Miosis, also known as pupillary miosis, refers to the condition of having small or constricted pupils.
Understanding Miosis
Pupils are the black circles located at the center of your eyes. In the case of miosis, the muscles of the iris—the colored part of your eye—tighten, causing the pupil to become smaller. This contraction of the iris muscles reduces the size of the pupil opening. Here’s a breakdown:
Key Aspects of Miosis
| Aspect | Description |
|---|---|
| Pupils | The black circles at the center of your eyes |
| Iris | The colored part of your eye |
| Mechanism | Muscles in the iris contract, tightening around the pupil |
| Result | Pupil becomes smaller or constricted |
Additional Notes on Miosis
- Miosis is often a normal response to bright light conditions, helping to reduce the amount of light entering the eye.
- It can also be triggered by certain medications, drugs or underlying medical conditions.
- When miosis is persistent or occurs for no apparent reason, it's recommended to consult with a healthcare professional.
- While miosis itself is a descriptive term, the causes for it can be varied and should be investigated for proper management.
