The Carcara plancus (Miller, 1777) is a diurnal predator of unusual eating habits and environmental adaptation that inhabits practically the entire Brazilian territory. Like other birds of prey, it needs good visual capacity for good performance of normal activities of the species, being the vision its most developed sense. Therefore, the aim of the present study was to evaluate the ophthalmic, ocular ecobiometric and electroretinographic parameters of 20 eyes of (10 animals) species from the Wild Animal Screening Center of Camaragibe, Pernambuco. Clinical data on tear production (Schirmer's tear test), corneal sensitivity (Cochet Bonnet esthesiometry) and intraocular pressure (rebound tonometry) were evaluated, as well as the measurement of different structures of the eye bulb using ultrasound ecobiometry in mode B. Total field electroretinography was also recorded in different protocols with white light stimulation and different wavelengths. Data were obtained for clinical and ultrasound tests with normal distribution and no significant differences were observed between the contralateral eyes. Ocular ecobimetry has shown that the parameters and proportions of the carcará eye are similar to the eyes of other daytime raptors. The electroretinography tracings presented the main components (wave a and b) and there was a response to the wavelength stimuli between the ultraviolet to the red, but it did not respond to the infrared stimulus. The present study offers information applicable of being used in the clinical ophthalmology of wild animals and to support new research.
