Major sympathy on the eye injection Tiggi. Had that twice now, first time I was close to vomiting. Not the pain so much, just seeing that bloody enormous javelin heading towards my eyeball whilst a nurse kept my face shoved into the restraint to stop me flinching
I have had it for nearly 20 years now (diagnosed in early 20s). I can sometimes go months between attacks, other times I am lucky if I make it to a week
stoppin - Try to push for further investigations if you can as there are many conditions it could be related too - mainly auto immune ones.
I am a little bothered that your DS has had steroids for 4 years. My consultant will not let me go past a month of constant use without changing the drug, or dragging me in for an injection.
Things to be aware of (sorry if I am teaching granny to suck eggs but I don't know what you know IYSWIM ) :
ANY irritation of the eye can set it off, so extreme care has to be taken with soap, shampoo etc. Also would recommend goggles for swimming. If he does turn out to be a life-long sufferer (and the bad news is, that is highly probable) he wont be able to wear contact lenses.
Another eye condition is common in iritis sufferers - blepharitis (infection of the lashes). It is not always obvious. Try bathing his eyes each morning in plain boiled water, single swipe with a fresh piece of cotton wool on each eye, downwards and outwards.
If I think of anything else, or you have any questions, yell.
