Clinical Context (Merck Veterinary Manual)
Ophthalmic emergencies, such as those presenting with a swollen eye, require rapid diagnosis and aggressive therapy to maintain vision. Traumatic proptosis, often from blunt trauma, can cause globe luxation and eyelid spasms, leading to orbital hemorrhage and swelling, further displacing the globe. Corneoconjunctival drying and malacia may follow. Nasolacrimal obstructions can also cause mucopurulent discharge.
