chloramphenicol eye drops

what do you think this is?

My 8 year old son, has a scar inside his eye lid that seeemed a bit red so i took him to our GP who gave him chloramphenicol ointment to use for 5 days, i may have accidentally used a bit too much as it came out fast, anyway after stopping using it 2 days later his eye appeard pink! it looks as though he has extra red veins in his eye. This has been like this for over 2 weeks now and it has not got any better even though our GP has given us some eye drops to use for allergies. Will this ever go or is it permanently damaged?

if i were you i would take him back to your gp
you are worrying your self unnecessarily and it could be something minor that will be cleared up in days
if you are concerned the eye drops are causing added irration i would stop putting it into his eye
boil water,cool until barely warm and bathe it two or three times a day
he may have rubbed his eye in his sleep and that would cause the redness that looks like another vein
best wishes i hope he is ok soon
