I came back from Tunisia about 3 weeks ago. The day after i got back i got nagging headaches and pains in my eyes. Lookin in the mirror, i noticed white lumps on the whites of my eyeballs. I have never worn suglasses, not even out in Tunisia. Anyways after a visit to my GP, then the opticians, then(last week) to my local eye hospital. It turns out that i have something called(tropical eye). Probably brought on from the job(wfp) but brought to a head while on holiday. I have been given eyedrops and told that it should go after a week or so, but i tell you, i was crapping for a bit. Wear sunglasses all the time now. I just hope it isn't a case of too little too late, in the sense that i have done damage already.
