  • Abstract
  • Look Inside

A 52-year-old slender and low-height woman presented with bilateral simple diabetic retinopathy and cystoid macular edema in the left eye. She had been diagnosed as diabetes mellitus 19 years before. Deafness set in 3 years before. Mitochondrial analysis showed mutation of adenine to guanine at mt DNA 3243. Cystoid macular edema resolved one month after laser photocoagulation. It appeared that the compromised function of retinal pigment epithelium, which is rich in mitochondria, might have been involved in the occurrence of cystoid macular edema.
