Background: Pupillary membrane persistence (PMP) is a congenital abnormality, which is not usually reported in felines.It is characterized by remnants of the fetal membrane that persist as filamentous tissue across the pupil. In general, thischange does not cause any clinical signs. However, the filaments may either attach to the cornea and cause small opacitiesin it or attach to the lens and cause cataracts. In most cases, there is no visual impairment, so treatment is not required.This report aims to describe a case of PMP in a domestic cat diagnosed at the Veterinary Hospital of the State Universityof Santa Cruz (HV-UESC).Case: A two-and-a-half-year-old mixed-breed castrated male cat was brought to the HV-UESC with dermatological complaints. Upon physical examination, the animal was alert with a body temperature, heart, and respiratory rate within thenormal parameters for the feline species. The lymph nodes were non-reactive, and the coloration of the oral mucosa wasnormal. There was no ophthalmic complaint from the owner, nor any loss of visual acuity. In addition, the animal hadmoderate pruritus, redness, and alopecia in the region of the ears, head, neck, chest, and back. Bristle samples were collected for an optical microscope analysis and an infestation with lice (Felicola subrostratus) was confirmed. An endectocidecontaining selamectin (15 mg; single application every 30 days) was prescribed. During physical examination, filamentoustissue crossing from iris to iris through pupil was observed in both eyes. The eyelid, corneal, and pupillary reflexes werewithin normal ranges. An ophthalmic evaluation did not identify conjunctival hyperemia or episcleral vessel congestion,and the eyelid, corneal, and pupillary reflexes were determined to be within the normal range. A slit-lamp biomicroscopydid not detect any anterior chamber alteration besides the filamentous tissue previously mentioned...(AU)
