My 2 year old son has developed a white lump on his eyeball (maybe could have been caused by one of his toy cars).
I took him to the paediatrician who said it was conjunctivitis and gave him some eye drops. But a week later and the redness and lump are still there and I'm not convinced that it is (just) conjunctivitis.
A quick Google suggests it could be 'pinguecula' - but he is not of 'old age' near do we live in tropical climes or other such high UV area (listed as in common with this condition).
Then again it could be both those conditions (because now my eye has subsequently also become red/sore, though there are no white lumps on mine).
I put some photos here, I'd be interested in a second opinion.
If it is Pinguecula do you know if it is here for life or will it fade away?
