What are the early signs of primary lens luxation in Chinese Cresteds

Based on the information provided in the search results, the early signs of primary lens luxation (PLL) in Chinese Crested dogs include: Sudden onset of eye pain and discomfort Clouding or bluish appearance of the cornea (the clear front part of the eye) Redness of the "white" part of the eye (sclera) Visible dislocation of the lens, which can be seen as a clear "half moon" shape in the pupil The search results indicate that PLL is a common inherited eye condition in Chinese Cresteds, where the ligaments holding the lens in place degrade and cause the lens to become dislocated. This can happen in either the forward (anterior) or backward (posterior) direction. Owners should watch for these early signs and have their Chinese Crested examined by a veterinarian promptly, as anterior lens luxation requires surgical intervention to prevent further complications like secondary glaucoma. Posterior luxation may not require immediate treatment but should still be monitored closely. Early detection and proper management of PLL is crucial to maintain the dog's vision and eye health. Genetic testing of breeding dogs is also recommended to help prevent passing on this condition to future generations.
