How prevalent is lens luxation among Sealyham Terriers?
We do not have an accurate estimate of the prevalence for lens luxation in the breed. We continue to collect enough reports about affected dogs to know that without an immediate and comprehensive effort to stop the spread of the gene, the problem could become much worse than it is now. As we gather more information in the SIGHT registry we are finding that a significant percentage of Sealys are probably carriers of the defective gene.
