Conjunctivitis, or pink eye, is inflammation of the conjunctiva – the thin, clear tissue that lines the eyelid and covers the white part of the eye. In addition, it causes redness, itching, swelling, and discharge that may crust over the lashes. Furthermore, in humans, pink eye can result from viruses, bacteria, allergies, or exposure to irritants like smoke or chlorine.
Types of Conjunctivitis
- Viral Conjunctivitis: Often linked to the common cold, this type spreads easily through contact with eye secretions.
- Bacterial Conjunctivitis: Caused by bacteria like Staphylococcus or Streptococcus. Also, it can spread through dirty hands or contaminated objects.
- Allergic Conjunctivitis: Triggered by allergens such as pollen, pet dander, or dust. In addition, it is not contagious.
- Irritant Conjunctivitis: Comes from exposure to smoke, chemicals, or chlorine. This type also isn’t contagious.
Dogs can also get pink eye, though their causes may differ slightly. When dogs get pink eye, it’s often linked to the environment, infections, or other health issues.

|---|
| Redness | Bloodshot appearance in the whites of the eyes | Physical Examination |
| Swelling | Puffiness around the eyes | Physical Examination |
| Discharge | Watery, mucous, or pus-like discharge | Conjunctival Swab |
| Itching | Frequent pawing or rubbing of the eyes | Physical Examination |
