2. Oval Pupils
May appear after eye injury or trauma.
Sometimes linked to glaucoma (high eye pressure).
Can also occur as a natural variation in some people.
👉 If you notice a sudden change from round to oval, it’s worth mentioning to an eye doctor.
3. Keyhole-Shaped Pupils
Known medically as a coloboma.
Present from birth in many cases, caused by a small gap in the eye’s structure.
May affect vision depending on its size and location.
Can appear alone or as part of certain syndromes.
👉 Many live with colobomas without issues, but they are rare enough to spark curiosity.
4. Irregular or Jagged Pupils
Can occur after eye surgery, trauma, or inflammation.
Sometimes associated with neurological disorders.
May appear uneven or notched around the edges.
👉 Some people don’t notice until looking very closely. If it’s new or worsening, seek medical advice.
5. Constantly Dilated Pupils
Pupils that stay large even in bright light.
Possible causes include:
Medications (e.g., stimulants, antidepressants, eye drops)
Brain or nerve conditions
Sometimes simply natural genetic variation
👉 It can look alarming, but not all cases are dangerous. Context matters.
Final Thoughts
Your pupil shape can sometimes reflect your eye health or hint at deeper medical issues—but it’s not a diagnosis on its own. Lighting, medications, or even stress can change how your pupils look.
📝 Reminder: If you notice sudden or dramatic changes in your eyes, consult a professional.
