[Ocular manifestations of myotonia atrophica].
In a 55-year-old male with a history of over 20 years of exposure to lead clinical, electromyographic and histological investigations demonstrated myotonic dystrophy. Cataract and high-grade concentric narrowing of the visual field were found bilaterally. The latter change has been reported sporadically in this disease. Detailed laboratory investigations failed to confirm lead intoxication. No genetic background has been elicited which may suggest the possibility of toxic exogenous factors in this disease but is insufficient for accepting this possibility.
