Uneven Sclera - Lucky_P

[inyati13]

I examined my calves eye because it was watering. I sprayed it with Vetericyn. During the examine, I noticed something that is a curiosity to me. The sclera of the eye has an uneven border in the right eye. Why? Just a natural variation or something going on?

Not an ophthalmologist, but my guess is that it's just normal variation in pigmentation.

Amazing isn't it--all the different things that have to come together just right, for something even as commonplace (in our minds anyway) as an eyeball---to look "perfect"?
Nature is pretty spiffy.

Fairly certain it's pigmentation...
Wish you had a good macro lens to get a better view.

On a tangent... I wish I had a good macro lens.

I say pigmentation because looking at it again, even on the calf's skin he's got spots of pigment, but the hair still grows out white.
Patterns can come out pretty unique on calves with "chrome"

I notice that too. Since hair and pigment is of dermal (vs epidermal origin), one would think the hair would have the same color as the pigment it is originating in. :cboy:

I like your chrome calves, Anne. :D

Melanocytes are of neuroectodermal origin - and they don't all manage to migrate from that embryonic tissue of origin to the epidermis.
I frequently see extensive areas of pigmentation in the meninges - especially in black cattle and black-faced sheep - similar to the conjunctival melanosis in that last photo.

Lucky, that is interesting that pigments occur in tissues where they are basically non-functional. Thanks.
