Here you go, both eyes of my 2 year old Appy/Sporthorse..
I never knew it was so difficult to take a photo of the eye!~
Is this normal discoloration of the Appy eye?
On the first day God created horses, on the second day he painted them with spots..

Ann have the pigmented areas been there since birth and has there ever been symptoms of eye inflammation?

Never eye inflammation,all my apps wear fly masks on sunny days even non fly days as well..
I really can't say if his eyes have been like this since birth.. I just noticed his left eye this past year with all the young work i have been doing with him.... It does not appear to effect his vision ..
I don't think my other apps have this kind of leaking in their eyes.. I will check them out today ..

hum , just checked my other apps.. nice clean lines on the cornea.. all tho there is some leaking in the front of the eye.. the second eye lid area.. I played with Tom today.. he does not seem to be bothered by his spotted eye.. I wonder he was born solid .. maybe here are his spots.. !! My barn vet said some appys have spotted brains.. a joke i am sure??

Hello Ann,
Since my original posting of the inflamed eye and increasing pigmentation with chronic inflammation I have gone in search of professional confirmation. It is well established though somewhat counter intuitive that with chronic inflammation highly pigmented skin can loose pigment and less pigmented skin increasingly pigmented. I have always felt this happens in the eyes. However none of my ophthalmology text books list increased pigmentation of the sclera as a diagnostic criterion of chronic scleritis (more correctly conjunctivitis of the sclera).
I can find cases where inflammation has reduced the normal pigmentation of the sclera. However I have long felt that I have seen no-pigmentation in chronically inflamed eyes. Most eyes that have problems with chronic conjunctivitis (including the sclera's conjunctiva) are those without much pigmentation so when I see one with remarkable pigmentation on the sclera I tend to believe it was associated with the inflammation. In some of these cases the pigment appears a bit different than the normal pigmentation in that it is darker (sometimes almost black) and with edges sharply demarcated. But I do feel the question remains open about whether my "feelings" are correct.

Some Arabs, especially those with large eyes, are born with pigment in the sclera that looks similar to this. Often it fills in, but sometimes it doesn't. Usually it's on gray horses.

Maybe I have still not been clear on this. Pigmented scleras is common in many horses and by itself not a sign of problems.
