A Case of Cystine Crystal Depositions within Cornea in Cystinosis

ABSTRACT

PURPOSE: We report a case of systemic cystinosis who showed cystine crystal depositions within cornea. METHODS: A 13-year-old boy with systemic cystinosis who had chronic renal failure, growth retardation, rickets for 9 years was consulted for ophthalmic examination for photophobia. We performed complete ophthalmic examinations including slit lamp examination, corneal pachymetry, corneal sensitivity test, specular microscopy, corneal topography, and fundoscopic examination. RESULTS: There were needle-like cystine crystal depositions within the entire corneal stroma. Other findings were within normal. CONCLUSIONS: We report a case of sytemic cystinosis that had cystine crystal depositions within cornea. It is the first case report in Korea.
