Ulcerative keratitis in paca (Agouti paca)
Keywords:Certite ulcerativa, Agouti paca, Pacas
Ulcerative keratitis is a disorder mainly caused by fights and scratches in rodents. This disorder was described in a 7-year-old female paca with ocular secretion, blepharospasm, chemosis, conjunctival hyperemia, edema and corneal neovascularization. After anesthesia using azaperone (1mg/kg, i.m.), ketamine (20mg/kg, i.m.) and xylazine (0.2mg/kg, i.m.), plus anesthetic collyrium (hydrochloride of tetracaine 0.5% and phenylephrine 10%), conjunctival covering of 360° was performed. Subconjunctival injection of gentamicine was done and the animal was kept using an Elizabethan collar in an individual pen, receiving analgesic (0.02mg/kg of buprenorphine, i.m.) three times a day for 2 days and pentabiotic every 48 hours during 10 days (30,000IU/kg of three penicillins and 12.5mg/kg of two estreptomicines, i.m.). After 30 days, important adhesion of the conjunctival bulb to the scarred cornea was noted and
phithisis bulbi observed. The surgical technique performed preserved the eye bulb although vision was lost.
How to Cite
This journal provides open access to all of its content on the principle that making research freely available to the public supports a greater global exchange of knowledge. Such access is associated with increased readership and increased citation of an author's work. For more information on this approach, see the Public Knowledge Project and Directory of Open Access Journals.
We define open access journals as journals that use a funding model that does not charge readers or their institutions for access. From the BOAI definition of "open access" we take the right of users to "read, download, copy, distribute, print, search, or link to the full texts of these articles" as mandatory for a journal to be included in the directory.
