When we agreed to take Q into our family we were aware he was diagnosed with Retinopathy/PRA while he was in Finland.
Fortunately for Q we had a second opinion performed by Dr. Aguirre of the University of Pennsylvania this past Sunday and his determination was it is simply mottling/discoloration that is apparently not uncommon with this breed as they age. They do not know what causes it but stated it is not a inherited condition.
He does have some small cataracts in his left eye but they should not adversely affect his vision.
Has anyone else had any experience with this mottling?
On a side note he stated they are getting very close to determining the gene that causes PRA in Basenji's and developing a test for it, hopefully sooner than later we can be rid of it in the breed.
