OBJECTIVE: The authors describe new ocular and electroretinographic (ERG) features in Menkes disease. DESIGN: The study design is a case report. PARTICIPANTS: The authors studied two patients with Menkes disease. INTERVENTION: The authors performed complete ophthalmologic and ERG evaluations in both patients. MAIN OUTCOME MEASURES: The parameters used were slit-lamp biomicroscopy and ERG recordings. RESULTS: Aberrant lashes and anterior stromal hypoplasia of the iris are new findings, and profound delays in b-wave implicit time in well-developed photopic responses may be added as new ERG features. CONCLUSIONS: Patients with Menkes disease may have aberrant lashes, anterior stromal hypoplasia, and retinal degeneration.

Twenty-four patients (47 eyes) affected by Graves' disease were enrolled to evaluate the role of standardized echography, pattern electroretinogram (P-ERG), visual evoked potentials (P-VEPs) and automated perimetry in the early diagnosis of the compressive optic neuropathy (CON). The P-ERG amplitude reduction was the most sensitive parameter to demonstrate an early impairment of the optic nerve (ON) function. We found a significant negative correlation between the ON diameter and the P-ERG amplitude. VEPs responses were also altered, but their ability in detecting an early ON damage was less sensitive and specific than P-ERG. The visual field damage was often aspecific and delayed with respect to electrophysiological alterations.
