Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is an autosomal recessive disorder of mitochondrial fatty acid beta oxidation. Patients with LCHAD deficiency demonstrate early-onset cardiomyopathy, hypoglycemia, hepatic steatosis, rhabdomyolysis, and peripheral neuropathy.1 Ocular manifestations include a pigmentary retinopathy that progresses to chorioretinal atrophy.2 Fundus autofluorescence is largely unexplored in LCHAD deficiency, but we have been using the noninvasive imaging modality of ultra–wide-field autofluorescence as a method of monitoring progression in these patients. The images (Figure) are from a girl in her teens with LCHAD deficiency controlled with a low-fat, high-carbohydrate diet. Best-corrected visual acuity is 20/60 OU. The ophthalmic findings are bilateral and symmetric. There is a peninsula of residual choroidal vasculature centrally, which is permitting her central acuity.
