Ophthalmology & Optometry/Pressure on the cornea


When pressure is applied onto the cornea wether it's from rubbing the eye a bit too hard with the knuckles or weathers its from a poke in the eye ,could the pressure force the aqueous humour onto the iris mainly on the outsides of the iris were the cornea ,aqueous humour and the iris are closer together ,could it result a change in iris color (darker or lighter discolouration)?

no. pressure is distributed evenly throughout the eye.  extreme pressure causes the cornea to become cloudy, and even blood to not be able to get into the eye resulting in blindness. brief pressure like a rub doesn't do anything.  if you think the iris is discolored on the periphery consider 'corneal arcus' Let me know or take a close up photo..
