I am currently undertaking a pHd in a microbiology laboratory and have begun suffering from a severe eye allergy to some chemical present in the lab where I work. I first had the reaction at the end of my honors year in the same lab when i noticed slight soreness and redness in both eyes and within 1 hour of these symptoms it progressed to severe swelling, very red, bloodshot eyes, and intense pain, and being firstly unable to close my eyes then progressing to being unable to open them and being very sensitive to light. After seeing several GPs which each gave me different diagnoses and treatments with ointments, antibiotics and antihistamines, I was eventually given the diagnosis of a severe allergic reaction and was taking 1 antihistamine tablet a day which prevented the reaction from returning. I then took a year off and have had no problems with my eyes. I have recently returned to the lab approx a month ago and have had the same reaction again (hence the assumption that the allergy is to something in the lab) and took the same antihistamine and used over the counter antihistamine drops which had no effect. I have been prescribed fluorometholone eyedrops and tobramycin ointment which have cleared up the allergy.
I am now faced with trying to figure out what I could be allergic to? and what can I do to manage this so that I can finish my work? Is it possible that I am breathing in a vapor which is presenting as a reaction in my eyes or must it have direct contact with my eyes? Is it possible to figure out what is causing my reaction with the 100s of chemicals present in the lab?
Some other notes which may help:
-I am very careful in the lab, I always wear gloves, don't touch my eyes, and wash my hands with microshield before leaving
-All hazardous chemicals which produce fumes are used in a fumehood
-I was not using any different chemical on the day I got the reaction than what I had been using daily for the past month
-I have been exposed to Ampicillin, Tetracycline, Streptomycin, Geneticin and Kanamycin and have not had any problem and Chloramphenicol is available in our lab but nobody has been accessing it.
Any information that could help me would be greatly appreciated!!
