What causes the iris of the eye to turn yellow?

Question

My eyes are naturually ocean blue, i recently discoevered that the tops of the iris in each eye, more the left than right have turned yellow just above the pupil in normal state. Im not talking about the small yellow lines most ppl have, an actual part of the blue has turned yellow. i've tried to look everywhere to find out whats going on. i know it isnt jaundice because the white of my eyes are not effected. any help would be much appreciated. thanks, Mike.

Answer 1

Mike,

There are several possible causes of iris color change.  Inflammation inside the eye; loss of the some of the pigment

making it look yellow or dull; circulation changes to the iris like diabetes and cholesterol.

Any of these possible causes need to be examined by an eye doctor, Board Certified Optometrist or Ophthalmologist.

If it is a change that has happened recently, then you should get it checked soon.

Answer 2

You may want to see a doctor, in case it's related to one of these:

"Lipofuscin is the name given to finely granular yellow brown pigment granules... Lipofuscin accumulation is a major risk factor implicated in macular degeneration..."

"Age-related macular degeneration begins with characteristic yellow deposits in the macula (central area of the retina which provides detailed central vision, called fovea) called drusen between the retinal pigment epithelium and the underlying choroid."
