• disease
  • In Stargardt disease, unlike geographic atrophy from AMD, the dense scotoma often far exceeds the size of the atrophic lesion on fundus autofluorescence, fluorescein angiography, or color fundus photos. (arvojournals.org)
  • Dense scotomas continue to enlarge over time in Stargardt disease. (arvojournals.org)
  • Treatment of scotoma is directed toward the underlying disease. (thefreedictionary.com)
  • As such, MacTel type 2 may serve a model disease for the study of parafoveal scotomas and their impact on function. (arvojournals.org)
  • optic
  • Less common, but important because they are sometimes reversible or curable by surgery, are scotomata due to tumors such as those arising from the pituitary gland, which may compress the optic nerve or interfere with its blood supply. (wikipedia.org)
  • visual
  • absolute scotoma an area within the visual field in which perception of light is entirely lost. (thefreedictionary.com)
  • positive scotoma one which appears as a dark spot in the visual field. (thefreedictionary.com)
  • relative scotoma an area of the visual field in which perception of light is only diminished, or loss is restricted to light of certain wavelengths. (thefreedictionary.com)
  • a scotoma outside of the central 30 degrees of the visual field. (thefreedictionary.com)
  • There is no direct conscious awareness of visual scotomas. (wikipedia.org)
  • The size of the monocular scotoma is 5×7 degrees of visual angle. (wikipedia.org)
  • A pathological scotoma may involve any part of the visual field and may be of any shape or size. (wikipedia.org)
  • The scotoma area may expand to completely occupy one half of the visual area, or it may also be bilateral. (wikipedia.org)
  • It has been suggested that filling-in is not accomplished by ignoring the absence of information of the scotoma but by an active visual process. (arvojournals.org)
  • An important gene associated with Scotoma is TMEM126A (Transmembrane Protein 126A), and among its related pathways/superpathways is the visual cycle I (vertebrates) . (malacards.org)
  • Yes, there is some "degenerated visual acuity" (scotoma) but its not anything you can't stop ignoring like the nose on your face. (wordpress.com)
  • size
  • For this reason, microperimetry is necessary for determining the size of dense scotoma and its enlargement over time. (arvojournals.org)
