UPPER AND LOWER EYELIDS AFFECTION

Eyelid abscesses are mostly subconjunctival and in some cases they are subcutaneous. The cause may be penetrating wound, embedded foreign body or hordeolum. Subconjunctival abscesses are present at the lateral canthus, upper eyelid and lower eyelid. The conjunctival abscess swelling extends over the eyeball and protrudes through the palpebral fissure preventing closure of the eyelids. Subcutaneous lid abscess leads to swelling of the eyelid preventing opening of the eyeball. Subconjunctival abscess at the lateral canthus in a cow

Treatment

Evacuation of pus is performed through a conjunctival incision. After squeezing and flushing of the abscess cavity, antibiotic eye ointment is applied. Subcutaneous lid abscess is drained through a skin incision.
