Case history and photos
History
Zero is a 26-month-old high white male housed with one cagemate.
Clinical Signs
The following were observed:
- porphyrin staining around right eye
- dryness of surface of the eye, like eye had not been closed good
- tiny lump on the surface of the eye (pimple-like)
Diagnosis
Corneal abrasion/perforation-healed
Treatment
After several days of home treatment with saline rinses and terramycin ophthalmic ointment the eye was neither better nor worse.
An appointment was made with the veterinarian. An eye stain showed the eye was scratched (possibly perforated), but as it was healing it formed a tiny bump. The vet explained that the iris of the eye came forward to fill the hole in the eye. She further explained that the eye will reconform and become smooth again. Tobramycin ophthalmic solution 0.3% drops were prescribed by the vet to be given 3 times a day to prevent infection.
Outcome
After 2 weeks of tobramycin drops the eye appears almost normal again.
