Plain-English summary
A Yorkshire Terrier mother and her son were found to have serious eye problems, including retinal dysplasia (abnormal development of the retina) and corneal opacities (cloudiness on the surface of the eye). The son was congenitally blind, and both dogs experienced retinal detachment and hemorrhages. Similar eye issues were also observed in other breeds, including Rough Collies and a German Wirehair Pointer, suggesting a possible link between these eye malformations and corneal cloudiness. Treatment details were not specified, but these findings highlight the importance of regular eye check-ups for dogs, especially those with known genetic predispositions.

Abstract
Mother and son of a Yorkshire Terrier family showed excessive multifocal retinal dysplasia (RD1) and geographical retinal dysplasia (RD2), intra- and preretinal hemorrhages partial and total retinal detachment (total RD/RD3), residues of the pupillary membrane and as a newness in this combination a geographical, subepithelial corneal opacity, composed of small dots. One, not examined son of the same litter was congenitally blind. Similar corneal opacities were also found in two Rough Collies affected with CEA, RD, and microphthalmia, a young German Wirehair Pointer with primary absolute glaucoma in conjunction with goniodysplasia and RD in the healthy seeming fellow eye as well as in a poodle puppy affected with bilateral posterior suture-line cataract in connection with persistent primary hyperplastic vitreous (PHPV) in one and a globe-shaped deformed retina in connection with a persistent, blood conducting hyaloid artery in the other eye. The latter finally resulted in intraocular hemorrhage and secondary glaucoma. A pathogenetic connection between ocular malformations and subepithelial corneal opacity seems to be likely.
