Primary lens luxation is the most common form of lens displacement encountered in the dog in the United Kingdom. The condition arises in early to late middle age, is essentially bilateral and occurs typically in the terrier breeds. Subluxation is rarely observed before 3 years of age but luxation of the lens is ultimately almost invariable. In Tibetan Terriers bred for the condition zonular changes were evident at least as early as 14 months of age. The condition could serve as a model for late spontaneous dislocations of the lens in man.
原发性晶状体脱位是英国犬类中最常见的晶状体移位形式。这种情况发生在中年早期至晚期，基本上是双侧性的，通常发生在梗犬品种中。半脱位在3岁之前很少见，但晶状体脱位最终几乎是不可避免的。在为这种情况培育的西藏梗犬中，至少早在14个月大时就明显出现了悬韧带变化。这种情况可作为人类晶状体晚期自发性脱位的模型。
