  • Title: Foveal cone electroretinograms in strabismic amblyopia: comparison with juvenile macular degeneration, macular scars, and optic atrophy.
    Author: Jacobson SG, Sandberg MA, Effron MH, Berson EL.
    Journal: Trans Ophthalmol Soc U K (1962); 1979; 99(3):353-6. PubMed ID: 298812.
    Abstract:
    A hand-held stimulator-ophthalmoscope was used to elicit foveal cone electroretinograms (ERGs) from fifteen patients with strabismic amblyopia. The ERGs were in response to a 4 degrees stimulus visualized on the fundus and centred on the fovea throughout testing. Foveal cone ERGs from amblyopic eyes were normal in amplitude and normal in b-wave implicit time. Interocular differences in ERGs in patients with amblyopia were no greater than those in normal subjects. Patients with comparable visual acuity loss due to macular scars or juvenile hereditary macular degeneration had abnormal foveal cone ERGs, while patients with optic atrophy had normal responses. These findings support the idea that the defect in strabismic amblyopia does not involve a functional abnormality in the fovea distal to the ganglion cell layer.
