Nonseeing area, or blind spot, within visual field, resulting from damage to visual pathways or to the retina. Blind spots exist normally in all eyes and mark the site of the optic nerve. See Free Eye Tests.
An area of deficiency in the visual field surrounded by normal areas. A scotoma is seen in normal vision at the point of the optic disk.
Area of depressed vision within the visual field, surrounded by an area of less depressed or normal vision.
Area of depressed or decreased vision in the visual field that is surrounded by an area of normal (or less depressed) vision.
A localized, disease-caused "blind spot" in the retina.
A blind gap in the field of vision.
area of depressed or lost vision within the visual field
A hole in the visual field resulting from damage to fibres in the visual system of the brain. The location and size of the scotoma helps the neurologist or neurosurgeon in locating the damage. Patients may be unaware of scotomas, due to the ability to "complete" the missing information and to use visual scanning to compensate.
Field loss that consists of isolated blind spots.
an isolated area of diminished vision within the visual field
a blind area or area of reduced vision within a visual field
an area of reduced vision in one or both eyes
an area of visual field in which the patient cannot see objects
a negative phenomenon consisting of a blanking or graying out of vision
an isolated area of depressed retinal sensitivity enclosed within the visual field
a non-seeing area in the visual field surrounded by a seeing area
a partial or total blindness in the retina of the eye
an isolated area of variable size and shape, within the visual field, in which vision is absent or depressed
An area of decreased or lost vision. Scotoma can be a characteristic symptom of migraine auras.
A blind or partially blind area in the field of vision.
a blind or partially blind zone in the visual field
An area of decreased vision surrounded by an area of less depressed or normal vision.
SkoH-Toe-Mah] A blind-spot or defect in the field of vision.
an area of partial or complete loss of vision surrounded by an area of normal vision.
and area of blurred or reduced vision.
A defect in the visual field which is surrounded by a normally functioning field; can be detected by perimetry.
A blind gap in the visual field.
The spot where damage to central vision has been great enough to cause loss of normal vision.
a blind spot, or area of diminished sensitivity in the visual field.
A blind spot in an area of otherwise normal vision.
an area of loss of sensitivity in the visual field.
a blind or dark spot in the visual field
A gap or blind spot in the visual field.
A blind or partially blind area in the visual field.
An impairment to vision a blind spot caused by diminished or total lack of function of the retina or optic nerve in a limited area. It may be unnoticed (Mariotte's blind spot) or be seen as a black area in the visual field.
An island-like area of lost or decreased vision in one or both eyes.
An area of partial or complete blindness caused by damage to the retina.
A blind area of reduced vision in the visual field.
Area of blindness of varying size anywhere within the visual fields. [Click Here To Return To List
A scotoma (Greek: darkness; plural: "scotomas" or "scotomata") is an area or island of loss or impairment of visual acuity surrounded by a field of normal or relatively well-preserved vision.
