Retinoscopia com luz em faixa em cães fácicos, afácicos e pseudofácicos

Abstract

The refraction error in dogs submitted or not to phakectmy, by phakoemulsification by streak retinoscopy was evaluated. Forty dogs were distributed in four groups of 10 animals each, and were designated by phakic, aphakic (AD), pseudo-phakic with two piggyback intraocular lenses (PD), and pseudo-phakic with one intraocular 41D veterinary lens implant (LD). The evaluation was performed by keratometry, ultrasonic echobiometry, and retinoscopy. The mean corneal curvature was 40.46±2.44D. The dioptric power obtained by retinoscopy was 18.50D in AD group, 5.25D in PD group, and 2.00D in LD group. The retinoscopy was an efficient method to evaluate ocular refraction in dogs, but was more complex in ocular opacity presence. All animals presented different levels of hypermetropy, and the surgically induced astigmatism was discrete. © 2009 Escola de Veterinária UFMG.
