A Case Report of Feline Infectious Peritonitis with Ocular Signs

Feline infectious peritonitis (FIP), same as panleukopenia, is one of the most fatal diseases in cats. This disease is observed in two forms: wet (effusive) and dry (noneffusive). This clinical report involves two cats with dry and wet forms of FIP with ocular signs.The ocular manifestation of this disease is usually alongside with the dry form. Chemosis, fibrinous discharges, congestion of the conjunctiva, bilateral glaucoma, retinal hemorrhage and finally blindness, were the symptoms of the first cat in this report. Due to the lack of paying attention to these symptoms, the infection was transmitted to the second cat which led to the wet form of disease. The definitive diagnosis of the wet form of FIP was confirmed with histopathology. Then, a chromatography experiment was performed in order to assess the main viral diseases in the first cat which was found to be positive for coronavirus. The ocular symptoms of FIP are often paid less attention, because they are similar to the other systemic diseases such as FeLV, FIV, toxoplasmosis and a number of fungal diseases.
