What is the cause of a white film on a puppy’s eye?

1. Causes of cataracts in dogs and cats: congenital and hereditary cataracts. Avoid puppies with congenital cataracts when choosing animals. Age-related: The lens of middle-aged and elderly animals will appear due to ageing. 2. Clinical signs of cataracts in dogs and cats: white areas are visible at the pupil, the animal is visually impaired or even blind, it may bump into furniture or objects when walking, and its flexibility of movement is reduced. 3. Diagnosis of cataracts in dogs and cats: The animal should be taken to a hospital with ophthalmology experience and equipment, and the doctor will carefully examine the entire eye with ophthalmic instruments. In addition to the extent of the lens lesion, the retinal function must also be examined. Mature cataracts may cause secondary uveitis, which often reduces the success of surgical treatment. 4. Treatment of cataracts in dogs and cats: At present, veterinary ophthalmologists worldwide unanimously recommend that surgical extraction of cataracts is the only reliable treatment. Currently, the most advanced surgical treatment is small-incision ultrasound emulsification combined with IOL implantation, with a success rate of over 80%. The success rate depends on the severity of the cataract, the complications and the general health of the dog. If the retina is functioning abnormally and is unable to transmit vision, then performing cataract surgery would be pointless. Cataract surgery in dogs and cats is a delicate micro-ophthalmic procedure and must therefore be performed in a hospital with appropriate and well-equipped surgical facilities.
