Current studies on hereditary eye diseases in dogs

Current studies on hereditary eye diseases in dogs use modern genomic research methods to better understand the genetic causes and inheritance patterns of these diseases. One focus is on identifying genetic mutations that are associated with specific eye diseases.

When studying distichiasis, a hereditary eye disease in which dogs develop extra eyelashes that can irritate the cornea, the assumption of polygenetic or mixed-monogenetic-polygenetic inheritance with a significant genetic defect is discussed. Distichiasis is particularly common in some Nordic dog breeds such as Samoyeds and Siberian Huskies and can be diagnosed at a young age.

Another focus is on primary non-congenital cataracts, which develop and are inherited independently of other eye diseases or general health conditions. This form of cataract appears in a typical location in the lens and progresses to the dog becoming blind. Currently, the only possible treatment is surgical removal of the affected lens, followed by implantation of a synthetic lens.

The studies highlight the importance of regular eye exams by certified ophthalmologists, especially for breeding dogs. This helps to detect hereditary eye diseases early and exclude affected dogs from breeding in order to minimize the spread of the diseases. However, research also highlights the limitations of this method, as some hereditary eye diseases only appear at a later age and carriers of the diseases are often only identified after breeding. Therefore, work is underway to develop genetic tests to minimize the risk of inherited eye diseases in future generations .
