 There's other ones too, like we look for congenital glaucoma, though that's very rare. We look for a condition called retinoblastoma, which is a cancer of the eye. It would show up as like we'd see leukocoria, which means you'd see basically the eyeball through the pupil being completely white or partly white. That's very rare. I can't say that I've seen that in my practice. But yeah, those are some of the more common ones and more obscure ones, I'd say. And there's others too, of course.
