Looking at your photo directly: I can see the globe held open by your fingers, a normal-appearing round pupil/dark iris, and mild redness (injection) concentrated at the inner/lateral corner of the eye where the conjunctiva meets the globe. I don't see a discrete white spot, opacity, or mass sitting on the iris itself in this image — the glare and dark iris pigmentation make the pupil-iris border hard to separate, but the surface itself looks smooth. The main abnormal finding I can actually confirm from the photo is localized conjunctival redness, not an iris lesion.

That said, a phone photo cannot reliably rule out iris/anterior chamber involvement — that needs a slit-lamp exam. This distinction matters because it changes urgency:

Red flags that would point away from "just conjunctivitis" and toward iritis/uveitis (ask yourself/check):

Bottom line: the photo shows conjunctival redness at the corner of the eye, not a clear iris lesion. If there's no pain, photophobia, or vision change, this is most likely just residual conjunctival injection from the conjunctivitis. But if any of the red-flag symptoms above are present, or if you or the person genuinely see a new spot/discoloration on the iris itself, this needs an in-person slit-lamp exam by an ophthalmologist soon - iritis/anterior uveitis can threaten vision if missed and isn't something to diagnose from a photo.

Can you tell me: is there eye pain, light sensitivity, or blurry vision, and is the "spot" a new pigmented/white area on the colored part of the eye or is it the redness at the corner that concerns you?
