Online published on 26 July, 2017. Abstract Electroretinography (ERG) is useful adjunct test for diagnosis of retinal dystrophies and for pre-operative evaluation of retinal functions in conjunction with cataract surgery. ERG recordings were done in 9 dogs with various vision abnormalities viz. cataract, retinal detachment, vitreous degeneration, retinal degeneration and glaucoma. The causative factor for vision abnormality in majority of cases was cataract (n=5, 55.55%) followed by retinal degeneration (n=2, 22.22%) and one dog each with glaucoma and chronic kidney disease (11.11% each). ERG was used to quantify the severity of retinal impairment in these animals. Top Keywords Dog, electroretinography, vision abnormalities. Top |
