We recommend that all Tibetan Terriers have their eyes examined over 2 years of age. Most eye diseases occur 3-4 years of age, therefore it's suggested not to use too young dogs for breeding. Tibetan Terriers should be examined annually - every two years, and it would be the best if last exam would have been done ~10 years of age.
When a Tibetan Terrier is examined, it is first examined without eye drops, and then with the eye drops.
The vet who does the research really does matter - some are clearly more focused and educated than others.
There have been misdiagnoses by "less educated" - even EVCO - vets, that also that have needed to be corrected by the panel.

| Basically a cataract is a kind of an eye disorder. Dogs are prone to this disease as much as humans. In truth, it is one of the most frequently reported eye disorder in dogs. Cataracts have an effect on the lens within the eyes and the chief job of this lens is to help eye focus the field of vision. When the lens of the eyes gets a certain level of cloudiness or if it becomes blurred, the condition is referred to as cataract. Following are the three stages of Cataract. Incipient Cataract: Incipient cataract is the mildest case of this disease. This type rarely interferes with the dog’s vision and the cloudiness is so slight that it is extremely difficult to determine its presence. Immature Cataract: Whenjust a part of the eyes appear cloudy, it’s called immature cataract. This form of cataract is more severe and causes blurred vision and it will be visible in your pet easily. Mature Cataract: When the cataract has covered the entire part of your dog’s eye, then the disease has progressed into mature cataract. What causes Cataract? Cataract is generally assumed to be an inherited disease in most dogs. In such cases the cataract can be observed in their first few weeks after birth. In other cases cataract can be seen as an old age issue known as senile cataracts, seen in dogs 6 years old or above. On the other hand, cataract can also be caused by trauma (Injury) in some cases. This can be due to one or multiple injuries caused by foreign particles. What are the signs of Cataract? - Change in eye color - Constant bumping into things - Reduced jumping and similar activities - Hesitant to explore new places - Blindness - Redness, pain, and inflammation in and around the eye area - Too much squinting → even if your dog do not have any of these signs, it can still have a cataracta. How is Cataract diagnosed? Vet may want to observe how your dog walks to look for any apparent signs of vision difficulty. Secondly for further diagnosis your vet may evaluate pupil size, symmetry and assessment of your dog’s pupillary light reflexes. The reflexes can also be determined by moving one hand towards your dog’s eye swiftly and stopping suddenly (maintaining safe distance to avoid any injury to eyes). In official ECVO-examination it can be proven easily. Other tests include following; - Throwing a cotton ball onto the floor while watching to see if the dog follows the movement. - Testing the pressure inside the eye using an instrument called a “tonometer.” - Dilating the pupils and using a penlight or other light source to characterize the nature and extent of the cataract and to evaluate for possible concurrent uveitis. (Anesthetic drops are normally applied to the eyes before these tests occur to ensure a painless examination and accurate test results). - Schirmer tear test and staining the eye with a fluorescein dye are other frequent methods to verify the wetness of the eye, to look for foreign bodies and determine if any damage to the cornea. - Ocular ultrasound and Electroretinography to assess the retina and rule out concurrent retinal degeneration (Usually performed if surgery is anticipated). | ||
Cataracta
Tibbet tulee silmäpeilata. Kun tibbe silmäpeilataan, se silmäpeilataan ensin ilman tippoja, ja sitten silmätippojen vaikutettua. Lääkärillä on oikeasti merkitystä - toiset ovat selvästi paneutuneempia sairauksiin kuin toiset.
On tullut virhediagnooseja joita on korjattu paneelissa.
There are several other eye diseases also.
Tiibetinterrierit pitäisi tutkia vuosittain - kahden vuoden välein vielä 10 - vuoden ikään asti.
