Cataracts. Conjunctiva (yellow - brown pigmentation of conjunc tiva and cornea). Conjunctivitis. Conjunctival xerosis (dry eye). Exophthalmos (protruding eyes). Xanthelasma (buttery eye lids). Abnormal pupil size. Strabismus (cross eyes). Discoloration of eyes (blue sclera). Discoloration of eyes (yellow sclera). Usually not an occupational dis ease, but traditionally associ- - ated with glass making, fur nace work, and other incan descent operations. Common from penetrating foreign bodies around lens. Frequently con genital, and frequent among diabetics. Many chemical causes, chiefly aniline and its derivatives, par ticularly hydroquinone. Almost unlimited; nonindustrial and industrial agents, such as vapors, acids, dust, ultraviolet rays (Klieg eye). Vitamin A deficiency. Usually bilateral from hyperthy roidism; monolateral from brain or eye tumors. Caused by fatty degeneration. Occurs chiefly in elderly pa tients, women more often than men. Caused by many drugs such as pin-point pupils by morphine. Commonly congenital. May arise after one-eye blindness. Familial disease unrelated to work. Usually jaundice. Disappearing as an occupational disease. R. M. I. May be accompanied by reddish discoloration of hair and skin of hands and feet. Seek out particular cause. Fre quently associated with respira tory tract inflammation. R. M. I. Thickening of conjunctivae over eyeball; vascular injection with growth over corneal margin in severe cases. Commonly unrelated to work ex posure; causes staring expres sion. R. M. I. When prominent, gives startling appearance to eyes. Pupil size abnormalities frequent from occupational diseases, as among pharmaceutical workers handling such chemicals as atropine. May be divergent or convergent. Congenital strabismus not al ways manifest in infancy. Part of well-established syndrome of brittle bones and blue sclera. Reflects liver damage possibly from industrial causes, such as carbon tetrachloride, or instead, infection or cancer. R. M. I. Use of suitable eye protection in hot and excessively luminous industries is preventing the occurrence of cataracts. Rare condition. One of commonest manifestations of industrial irritants. One red eye more likely to be industrial than two red eyes. More general distribution than pterygium. Associated with tremors, sweats ing, flushed skin, agitation, other aspects of thyroid syn drome. Harmless except for cosmetic un sightliness. Frequently re moved surgically by those who can afford it. R. M. I. May arise as acute state after brain hemorrhage. For confirmation, observe other members of the family. Look for jaundice of skin or bile in urine. (continued) VISIBLE MAHKS OF OCCUPATIONAL DISEASES
