21 Possible Causes for Relative Sparing of Periphery

  • Median Neuropathy

    The fibers placed at the periphery of the nerve trunk were relatively spared, which accounted for the pupillary sparing.[scielo.br]

  • Susac Syndrome

    sparing of the periphery) 1-2,8,11,16 lesions are small (3-7 mm) and resembling 16 : 'snowballs' on T2 andFLAIR when acute 'punched out' holes on T1 when chronic lesions,[radiopaedia.org] Although any part of the corpus callosum may be involved in Susac syndrome, the callosal lesions typically involve the central fibers with relative sparing of the periphery[ajnr.org] […] the periphery [ 7 ].[synapse.koreamed.org]

  • Retinitis Pigmentosa

    In contrast, the extreme periphery and the macular region appear relatively spared, although mild macular involvement is frequent.[ojrd.com] Fundus examination (Figure 2 ) reveals the presence of bone spicule-shaped pigment deposits in the mid periphery, along with atrophy of the retina.[ojrd.com]

  • Macular Dystrophy with Central Cone Involvement

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

  • Idiopathic Interstitial Pneumonia

    Note that the periphery of the lobule is relatively spared (H&E, 40). FIGURE 4 Bronchiolocentric interstitial pneumonia.[nature.com]

  • Desquamative Interstitial Pneumonia

    Note that the periphery of the lobule is relatively spared (H&E, 40). Figure 4 Bronchiolocentric interstitial pneumonia.[nature.com]

  • Trigeminal Nerve Lesion

    The fibers placed at the periphery of the nerve trunk were relatively spared, which accounted for the pupillary sparing.[scielo.br]

  • Reis-Bucklers Corneal Dystrophy

    The central cornea is usually spared, and the cornea is relatively clear between the lines. Lattice dystrophy type III.[slideshare.net] The deposits are fewer, coarser, and most dense in the corneal mid-periphery, and generally extend to the limbus with a more radial orientation.[slideshare.net]

  • Panuveitis

    Spread is relatively slow, approximately 25 μ m per day, often circumferentially, with sparing of posterior pole until late in the disease.[entokey.com] […] frosted branch configuration, often associated with retinal hemorrhages; and (d) the indolent form: white, granular appearing retinitis without hemorrhage—common in the periphery[entokey.com]

  • Pellucid Marginal Degeneration

    As the disease continues, the thinning may extend to the inferior cornea, sparing the interpalpebral periphery.[nhp.gov.in] There is relative steepening of interpalpebral peripheral cornea, resulting in against-the-rule or oblique astigmatism.[nhp.gov.in]
