Refsum's disease: electron microscopy of an iris biopsy. [PDF]

British Journal of Ophthalmology, 1990
Refsum's disease (phytanic acid storage disease) results in an accumulation of lipid as a result of an absence of mitochondrial hydroxylation of phytanic acid. We describe a previously unrecorded electron microscopic study of lipid deposition in the iris pigment epithelium of a patient with Refsum's disease, and lipid was present in other sites within ...
