The visual impairment and inscrutable disease of Samuel Johnson.
Samuel Johnson, the acclaimed author of the Dictionary of the English Language, survived childhood scrofula with impaired sight and hearing. The cause of his scrofula has been attributed to bovine tuberculosis, but mycobacterial infection does not satisfactorily account for the peculiar features of Johnson's eye disorder or his hearing loss. The subject of numerous biographies, Johnson may have the most scrutinized medical history of all time. Medical detectives, hampered by the vagueness of 18(th)-century diagnosis, suspect that phlyctenular eye disease related to tuberculosis was the reason for his visual impairment. Pediatric brucellosis can also explain childhood scrofula associated with visual and auditory disabilities, but it may be difficult to reconcile any single diagnosis given the uncertainties surrounding Johnson's medical and ocular histories.
