Pre-septal cellulitis is an infection of the eyelid and surrounding skin in front of the orbital septum. It causes redness, swelling, and tenderness but usually does not affect eye movements or vision.
Causes and symptoms
The infection often starts from local skin breaks, insect bites, or spread from nearby sinus or eyelid infections. Children are commonly affected but adults can develop it too.
- One eyelid becomes red, puffy, and warm to touch.
- There may be mild discomfort but usually no deep eye pain.
- Eye movements and vision remain normal.
- Fever or feeling unwell can occur in some cases.
- Examination is essential to rule out more serious orbital cellulitis.
Treatment and safety
Prompt antibiotic treatment usually leads to quick improvement. Monitoring is important because, rarely, the infection can spread deeper.
- Oral antibiotics are often sufficient for mild to moderate cases.
- Severe swelling, high fever, or poor response may need hospital care.
- Cold compresses and pain relief improve comfort.
- Seek urgent review if pain worsens, vision changes, or eye movements become painful.
- Early treatment helps prevent complications and scarring.
