Since young, this Shih Tzu has two large cherry eyes but during vaccinations by the other vets, the owner was not told that the cherry eyes can be tucked in. 

So, over the years, the dog rubs and rubs his cornea, leading to pigmentation of the corneas and blindness. Also the eyes are now dry and pus accumulates daily.

When the dog comes for yearly vaccination, advise the owners of any health problems and record them in the case files. It is up to the owner to act on the advices. In this case, he says no vets had informed him of the cherry eyes when he sent the dog for vaccinations yearly. 

In this case, the dog would not have been blind with hyperpigmented corneas (pigmentary keratitis) if his cherry eyes had been treated surgically when he was young. The cherry eyes are irritating, leading to daily rubbing and causing trauma and friction to the corneas. Over the years, pigments from the self-inflicted rubbing deposits on the cornea, leading to the black cornea and blindness at 11 years of age.
