5 Possible Causes for Relative Sparing of Fovea

  • Acute Zonal Occult Outer Retinopathy

    […] at the fovea.[] Usually, the visual acuity is minimally affected. 1, 3 However, in the subacute or chronic presentation, visual acuity was only mildly affected because of relative sparing[]

  • Cystoid Macular Dystrophy

    Marked thinning of outer photoreceptor structures in atrophic zone; relative sparing of fovea Well-defined atrophic area of absent FAF outside fovea Visible remaining hyperfluorescent[] […] increased and decreased FAF Speckled hyperfluorescence (mild RPE window defect) Normal Stage 3 20/27 (20/100 – 20/16) Appearance of profound chorioretinal atrophy outside fovea[]

  • Macular Dystrophy with Central Cone Involvement

    Fundus anomalies are variable and include bull's eye maculopathy, severe atrophy of central fovea, relatively spared fovea with surrounding atrophic ring, central retinal[] […] pigment epithelium and/or choroid changes, pale or atrophic peripapillary area, pale optic disk, relatively spared periphery, and slightly or moderately attenuated vessels[]

  • Ichthyosis - Oral and Digital Anomalies Syndrome

    The fundus has changes typical of retinitis pigmentosa such as a salt-and-pepper retinopathy and narrowing of the arterioles with relative sparing of the fovea.[]

  • Quinine

    It appears that in this case of bilaterally negative ERGs that the macula/fovea (which has a vascular supply through the choroid) is relatively spared as is seen in bilateral[]
