Ocular foreign bodies (grass seeds, feed material, bedding material, dust) may enter and irritate the eye, predisposing to inflammation and infection. Risk factors in the live export process include:
Affected eyes may be partially or wholly closed or weeping. A foreign body in the eye is usually located in the lower conjunctival recess and rarely in the upper recess. A proper examination requires good physical restraint aided by sedation, topical anaesthetic, and a light source (head lamp). Differential diagnoses include pinkeye and IBR.
Foreign bodies may be removed with forceps during the examination process, using appropriate restraint, sedation, and topical anaesthesia as required.
Topical antibiotics in the form of spray or ointment can be applied to the eye, however parenteral administration of antibiotics (procaine penicillin, oxytetracycline, erythromycin, trimethoprim sulpha, or tylosin) will be easier, more effective and longer lasting.
Avoid applying antibiotic powders to the eye as they are irritating and may worsen the problem.
