Avaliação ultrassonográfica ocular em cães: catarata e alterações secundárias e concomitantes

Abstract

In ophthalmology, ultrasound exams are increasingly frequent, especially when the transparent media of the eye are shown opaque, as in certain stages of cataracts. The relevance of the cataract in the clinical routine of pets, especially dogs, aimed to perform a retrospective study of eye care to identify the main ocular cataracts in association with the Veterinary Hospital, Small Animal Industry of the Federal Rural University of Rio de Janeiro and two private clinics in the municipalities of Resende and in the southern city of Rio de Janeiro, in a period of two years (2009/2011), with emphasis on sonographic reports of dogs with cataracts. Were evaluated by ultrasound (B-mode) 90 dogs and 180 eyes, 164 eyes with cataract. As concomitant changes cataracts were detected: increased cellularity in the vitreous chamber (84/154), dislocation of crystalline (2/154), neoplasia (2/154), decrease size and / or diameter of the lens (24/154), retinal detachment (8/154), axial length increased (5/154) and crystals (2/154). Comparing the right and left eyes there was no significant difference regarding the parameters analyzed. The high prevalence of ocular alterations concomitant cataract demonstrates the importance of ocular ultrasound examination as preoperative cataract surgery.
