PURPOSE: To assess the multifocal electroretinogram and full-field electroretinogram findings in a patient with advanced central areolar choroidal dystrophy. DESIGN: Observational case report. METHODS: A 53-year-old man with central areolar choroidal dystrophy underwent multifocal electroretinogram and full-field electroretinogram testing. RESULTS: The multifocal electroretinogram demonstrated relative preservation of foveal function compared with the severely depressed retinal function of the perifoveal macula corresponding to the location of the retinal and retinal pigment epithelium atrophy. The full-field electroretinogram was normal for both photopic and scotopic responses. CONCLUSION: Despite a normal full-field electroretinogram, the multifocal electroretinogram demonstrated significant macular dysfunction with relative preservation of foveal function in a patient with central areolar choroidal dystrophy.
