Leopard spot retinal pigmentation in infancy indicating a peroxisomal disorder.

摘要

BACKGROUND: Neonatal adrenoleucodystrophy (NALD) is a rare disorder resulting from abnormal peroxisomal biogenesis. Affected patients present in infancy with developmental delay, hypotonia, and seizures. Blindness and nystagmus are prominent features. The authors suggest a characteristic leopard spot pigmentary pattern in the peripheral retina to be diagnostic. METHODS: Three patients are reported with this presentation; the characteristic retinal appearance resulted in early diagnosis for one of these. CONCLUSION: Leopard spot retinopathy in an infant with hypotonia, seizures, developmental delay, with or without dysmorphic features and hearing impairment, is a clue to the diagnosis of NALD.
