Conjunctivitis, occupational allergic

A number of diseases are recognized as being, or presumed to be, allergic in nature. These include asthma, rhinitis, conjunctivitis, allergic contact dermatitis, urticaria (a condition in which red or pale, itchy, and swollen areas appear on the skin, often called hives ), and food allergies. In this section, the endpoints discussed are those traditionally associated with occupational and consumer exposure. Photosensitization is potentially important but its mechanism of action is poorly understood, so it has been considered but not discussed in detail. 

All isocyanates are known to cause pulmonary toxicity. Isocyanates are the most common causes of occupational asthma and have led to the development of immediate or late asthma among workers. Isocyanates have caused bronchitis, rhinitis, conjunctivitis, chronic obstructive lung disease, contact sensitivity, dermatitis, allergic alveolitis, and immunologic hemorrhagic pneumonitis.29... 

An allergic conjunctivitis was seen in cases of industrial occupational skin reactions to albendazole (26).

Second phase The worker complains of conjunctivitis, a catarrhal state of the mucous membranes of the nose, larynx, and respiratory passage. Coryza, hoarseness, and mild tracheobronchitis may occur. Perforation of the nasal septum is common, and is probably the most typical lesion of the upper respiratory tract in occupational exposure to arsenical dust. Skin lesions, eczematoid and allergic in type, are common.
