| Abstract |
|
Isocyanates are part of a group of important chemicals necessary in the production of adhesives, synthetic rubbers, and a variety of plastics. They are known to have minimal toxic effects when administered locally. However, we experienced a case of damage involving the entire eyeball in a person who accidentally exposed his eye to isocyanates. The patient presented with inflamed conjunctiva, and shrunken cornea and sclera, with focal atrophic changes in the iris. The lens and vitreous were opacified. After removal of the lens and vitreous, there were large areas of atrophic retina and areas of retinal necrosis with holes. We found that locally absorbed isocyanates can cause damage to the entire eyeball. Therefore, we recommend that if there is any evidence of isocyanate penetration, early vitrectomy should be performed to help in determining the extent of retina damage and to decrease the amount of toxic substance in the vitreous. |
