Subconjunctival abscesses of the nictitating membrane are most common in cattle and buffaloes. Foreign body penetration or trauma appears to be the main cause of the condition. The third eyelid is protruded and extends over the cornea obscuring the animal vision.

Treatment:
The abscess is incised vertically at the palpebral surface of the conjunctiva and the contents are evacuated. Lavage of the abscess cavity and the eyeball is performed with mild antiseptic solution. Antibiotic ointment is applied twice daily for 5 successive days.
