On December 10 of 07, my 4 y.o. son had a tonsillectomy and a intramuscular injection of Kenalog - 40 in to his turbinate of his nose. a week later my wife and I noticed a problem with his left eye. Went to opthamologist and he said he was blind in his left eye. It is not recommended to give Kenalog by route of interburinate due to severe cases of blindness.
