  • These features are typically followed by impaired color vision (dyschromatopsia), blind spots (scotomas) in the center of the visual field, and partial side (peripheral) vision loss. (medlineplus.gov)
  • For example, rods allow for peripheral vision to the far left and right of your field of view, while cones enable central vision and help you see details and colors in your field of view. (esighteyewear.com)
  • While central vision varies, the hallmark of this disorder is the presence of severe visual impairment with a deceptively preserved retinal structure. (nih.gov)
  • Visual field abnormalities are variable and include generalized depression of visual field, paracentral or peripheral scotoma and enlargement of the blind spot. (wikipedia.org)
  • The clinical diagnosis of ON consists of the classic triad of visual loss, periocular pain and dyschromatopsia which requires careful ophthalmic, neurologic and systemic examinations to distinguish between typical and atypical ON. (openophthalmologyjournal.com)
  • The disease has characteristics of poor visual acuity (due to central scotoma), photophobia, severe dyschromatopsia and occasionally nystagmus. (cdc.gov)
  • Progressive loss of vision, dyschromatopsia, and photophobia are the primary ocular symptoms. (arizona.edu)
  • Symptoms that may eventually develop include paracentral scotoma, decreased visual acuity, metamorphopsia, and photophobia. (aao.org)
  • 18 In keeping with other forms of cone-rod dystrophy, these patients typically present with reduced central vision, photophobia and reduced colour vision, but the significance of AF abnormalities in these disorders has not previously been ascertained. (bmj.com)
  • Presentations like central or paracentral scotoma, Floaters and dyschromatopsia are less common. (wikipedia.org)
  • Visual field abnormalities are variable and include generalized depression of visual field, paracentral or peripheral scotoma and enlargement of the blind spot. (wikipedia.org)
  • The optic nerve is continuous at one end with the retina and at the other end with the brain, making it vulnerable to a variety of both ocular and central nervous system (CNS) diseases. (clinicalgate.com)
  • Optic neuropathy, which is primarily retrobulbar, is the most common adverse effect of ethambutol and takes two forms - central and peripheral. (epomedicine.com)
  • Typically show central scotomas or bitemporal defects and, less commonly, peripheral constriction. (epomedicine.com)
  • Persons with OPA1 have scotomas (areas of impaired visual acuity) in the central visual fields and sparing of the peripheral visual fields. (nih.gov)
  • These features are typically followed by impaired color vision (dyschromatopsia), blind spots (scotomas) in the center of the visual field, and partial side (peripheral) vision loss. (medlineplus.gov)
  • the increased width is mainly due to the addition of myelin (seen as white within the ON in A ). C and D, Cross-sections (low and medium magnification, respectively) of the ON show the central parenchyma that contains axons, central retinal artery and vein, other blood vessels, astrocytes, oligodendrocytes, and pial septa.
