Abstract

Abstract Rhegmatogenous * retinal detachment, retinal breaks, developmental abnormalities, degeneration of the peripheral retina, juxtapapillary staphyloma, chorioretinal dysplasia, and retinoschisis have been described in several breeds of dog.1-5 To determine whether clinically detectable changes in the vitreous body are related to these conditions, the vitreous cavities of 24 affected collies were examined in detail. This paper is a description of the biomicroscopic findings and their correlation with the fundus abnormalities previously reported in these animals.1 Materials and Methods The collies, 9 males and 15 females, ranged in age from 5 months to 4 years. A complete fundus drawing was made of each of the 48 eyes and was used as a guide for study of the vitreous with the Zeiss Opton slit lamp and a three-mirror contact lens. When a small palpebral fissure precluded the use of the standard three-mirror lens, an especially designed contact lens with an adjustable mirror References 1. Due to a retinal break 2.
