OBJECTIVES: I. Determine the proportion of patients with cystinosis who experience a serious adverse effect when treated with a new formulation of cysteamine hydrochloride for corneal cystine accumulation.
II. Determine the proportion of patients with a reduction in corneal crystal density of 1.00 unit when treated with this regimen.
