Summary
Bacterial infection causing dacryohemorrhea (epistaxis from the lacrimal system) in horses was successfully treated. Antibiotics administered systemically and locally resolved the unilateral nasal bleeding in two equine cases.
Area of Science:
- Veterinary Medicine
- Ophthalmology
- Equine Health
Background:
- Unilateral epistaxis in horses can have various causes.
- Inflammation of the nasolacrimal duct is a potential, though less common, source of nasal hemorrhage.
Observation:
- Hemorrhage was observed originating from the nasal opening of the nasolacrimal duct in two horses presenting with unilateral epistaxis.
- This indicated inflammation and infection within the distal lacrimal system.
Findings:
- The condition, termed dacryohemorrhea, was attributed to bacterial infection.
- Successful treatment involved a combination of systemic and locally instilled antibacterial drugs.
Implications:
- This study highlights the importance of examining the nasolacrimal duct in cases of unexplained unilateral epistaxis in horses.
- Prompt diagnosis and targeted antibacterial therapy can effectively resolve dacryohemorrhea.
- Understanding this condition improves diagnostic and treatment protocols for equine nasal and ocular conditions.
