... sampling on 303 people who had history of exposure to chemical weapons in February 2009 in Sulaimany, Iraq. Medical history, symptoms, ocular conditions, clinical course, and treatment measures were reviewed. Statistical analysis was accomplished using SPSS/18, Chisquare test. Results: The present samples comprised of 49.8% were male and 50.2% were female. The mean age of the patients was 43.7 ± 13.1. Ophthalmic symptoms including tearing (96.7%), itching (96.0%), red eye (95.4%), blurred vision (84.2%), and vision loss (37.3%) were most common in subjects from Halabja, who also made up the majority of participants. Moderate to severe mustard gas keratitis was seen in 12.9% subjects (n=39), and severe complications were most common in subjects from Dukan. Conclusion: The investigation findings suggest that the need of Iraqi Kurdish chemical warfare victims with moderate to severe ophthalmologic complications for the provision of healthcare and follow-up is urgent. Further research also is necessary to measure the results of follow-up on Kurdish victims with mustard gas keratitis.
