Multiple Ocular Anomalies (MOA) are multiple congenital or developmental anomalies in the eyes of the same individual. Examples of defects included in MOA are microphthalmia, microphakia, congenital cataract, lenticonus, persistent hyperplastic tunica vasculosa lentis (PHTVL)/ persistent...

Lens luxation is caused by weakening of lens zonules, which leads to the displacement of the lens. Primary lens luxation (PLL), in which lens zonules are weakened with no antecedent ocular disease is a hereditary disease and the most common cause of lens luxation. Lens luxation can also be ...

The present study was aimed at evaluating the incidence of echographic abnormalities in the posterior segment of canine eyes with cataracts. Data were collected from medical records of 106 dogs with immature, mature or hypermature cataract, representing 175 eyes. These animals were seen for...

To give the veterinarians the information they need in practice, this article is focused on ocular diseases proven or suspected to be hereditary in purebred dogs, divided, according to their origin, in congenital and acquired. Among the congenital are considered, for example: persistent pupillary...

Objective: To analyze the change in prevalence and incidence of hereditary eye diseases (HED) in dachshunds due to breeding regulations based on biennial examinations performed by the German panel of veterinary ophthalmologists (DOK) from 1998 to 2011. Animals included: A total of 12 242 dachshunds ...

The results of ophthalmological examinations of 615 single-colored English Cocker Spaniels (ECS) were used for prediction of breeding values for primary cataract (CAT) and two different age-related forms of primary cataract (CAT-early and CAT-late). Breeding values (BV) for CAT, CAT-early and...

The material of the present study was composed of 30 eyes with luxatio lentis occurring in 20 dogs. Unilateral lens luxation was determined in a half of the animals while bilateral luxation was determined in the other half. Lenses in 19 of the 30 eyes were luxated in the anterior direction (63.3%), ...

Congenital and inherited ocular diseases are reported less frequently in the cat than the dog. The 2 species also differ in their array of disorders, with familiar canine abnormalities like cataracts overshadowed by unique feline diseases such as eyelid agenesis and corneal sequestration. Organized ...

Primary cataracts are breed-related eye diseases and are common in many dog breeds. In this study, 17 genes (BFSP2, EYA1, FOXE3, FTL, GCNT2, GJA3, GJA8, HSF4, MAF, MIP, PAX6, PITX3, SIX5, SORD, SOX1, SPARC, TRNT1) were evaluated as candidates for primary non-congenital cataracts (CAT) in the...

We analysed the systematic environmental influences and the additive genetic variation for the presumed inherited eye diseases (PIED), membrana pupillaris persistens, distichiasis, primary lens luxation, non-congenital cataract, and progressive retinal atrophy, in Tibetan Terriers. Data were...
