Phlyctenular keratoconjunctivitis
What Is Phlyctenular Keratoconjunctivitis?
Phlyctenular keratoconjunctivitis (PK) is a rare and painful eye condition. It is an inflammation of the cornea, which is the clear, dome-shaped front layer of the eyeball. PK appears as small, white bumps on the eye surface called “phlyctenules.” The bumps generally form the shape of a crescent or a half circle.
PK is typically caused by an allergic reaction to a bacterial infection, such as that of the Staphylococcus strain. It can also be triggered by a viral infection. If left untreated, the condition can lead to serious damage to the cornea and even blindness.
Symptoms of Phlyctenular Keratoconjunctivitis
The following symptoms are associated with PK:
- Swelling and redness in the eyes
- Pain, irritation, and tenderness in the eyes
- Sensitivity to light
- Pain when blinking
- Excessive tearing
- Blurred vision
- The appearance of small, white bumps on the eyes
Treatment For Phlyctenular Keratoconjunctivitis
Treatment for PK may include the following:
- Antibiotic eye drops: These can be used to treat bacterial infections that may be causing the condition.
- Corticosteroid eye drops: These can help reduce inflammation and pain associated with the condition.
- Anti-inflammatory drops: These can reduce inflammation and help reduce the severity of symptoms.
- Surgery: In some cases, surgery may be needed to remove the phlyctenules.
Prevention of Phlyctenular Keratoconjunctivitis
The best way to prevent PK is to practice good hygiene and to avoid contact with infectious substances. For example, you should:
- Avoid touching your eyes without first washing your hands
- Avoid sharing eye makeup or contact lenses
- Clean contact lenses properly
- Avoid rubbing or scratching your eyes
