—The excellent article "Ocular Cystine Deposits in an Adult" mentions that, "From this childhood type of cystinosis, a benign type has to be separated which is limited to adults and has so far been seen only in a few cases."Dr. Wong and I in the Journal of Pediatric Ophthalmology (6:195-197, November 1969) presented the case of an 11-year-old and her 16-year-old brother with the cystine deposits. At that time we suggested that the term "benign" rather than "adult cystinosis" be used to characterize the disorder because the lesion was seen in these adolescents.
