What specific health defect, characterized by crossed eyes, often affects inbred white tigers?

Strabismus

The intensive inbreeding required to consistently produce the rare white coat phenotype, primarily traced back to the Mohan lineage, has resulted in severe welfare concerns for the resulting captive population. A significant percentage of these inbred white tigers suffer from numerous debilitating genetic defects. One particularly noted condition is strabismus, which manifests as crossed eyes. This abnormality is directly linked to the white gene itself and causes measurable functional issues, including a reduction in the animal's spatial orientation abilities and increased sensitivity to light, known as photophobia. Along with strabismus, survivors of poor breeding practices frequently exhibit other serious issues such as spinal deformities and hip dysplasia.
