Half blue iris and half brown iris is not common but is normal in this eye.
Corpora nigra on the lower (ventral) margin of the iris. Rare but OK. Note the more normal looking corpor nigra on the upper (dorsal) margin of the iris. This enlargement is said to exist to provide shade to the retina when grazing like the bill of a baseball hat.

There are 3 things to note here: 1) an obvious defect at the facial crest caused either from trauma or surgery, 2) a linear skull depression most likely from trauma, and 3) the eye has a large, round lower corpora nigra.
