   The point where your optic nerves converge to exit the eye and into the brain is known as the optic disc. This area of the eye has no light-sensitive cells to detect light rays. This results in a break in the visual field known as your “blind spot.” When the cross mark disappears, you instead “see” a continuous white field.

   Blind Spot. • Hold a test strip out at arm’s length with the black dot on the left and segmented line on the right. • Close your left eye, and use your right eye to look at the black dot.

   Multiple regression has a previously unrecognized “statis tical blind spot” because when multicollnearity and measurement error are present, both path estimates and va riance inflation factors are biased.

   The blind spot indicates the location of the optic nerve head—an area with no photoreceptors—in the temporal part of the visual field. Anything obstructing the travel of light towards the retina may affect the field tests, for example, lens opacity (cataract), ptosis (if not taped away from the pupil) or the rim of a correcting lens (test ...

   Sep 8, 2018 · Statistical Analyses. Each Eyecatcher test yielded 46 DLS test scores (44 test points, and an upper/lower blind spot). To convert these values into an overall index of mean sensitivity (MS) the 44 test points were mean averaged, excluding the two blind spot locations.

   What does a blind spot indicate?

   • The blind spot indicates the location of the optic nerve head—an area with no photoreceptors—in the temporal part of the visual field. Normal hill of vision. During a Goldmann field test, the patient positions their eye opposite the centre of a white hemispherical bowl (figure 2).

   What are the characteristics of blind spot size and location?

   • Characteristic features of blind spot size and location, when evaluated with automated perimetry: Values obtained in normal subjects. Repeatability of measurements was found excellent for clinical purpose. Along the vertical axis, poorer reproducibility was found with weak stimuli, probably due to the presence of angioscotomata.

   Why do we never notice the blind spot in our vision?

   • After doing this test, a classmate says, “I bet the reason we never notice the blind spot in our vision is because our other eye is always open and it lets us know what is in the blind spot.” Do you agree or disagree with this statement? Write your reasoning. (Hint, the diagram provided might help you to make your decision.)

   What is the normal blind spot size in papilloedema?

   • This is particularly relevant in papilloedema (figure 5). The normal blind spot size is oval, roughly 10° in diameter, and located 10–20° temporally from the central fixation point. Is the central field affected?

   How do you see a black dot on a eye test?

   • • Close your left eye, and use your right eye to look at the black dot. (You will notice that even though you are looking only at the black dot, you can still see the segmented line with your side vision.) • Slowly move the test strip toward your right eye, making sure to look only at the black dot.

   What is the difference between Mean Deviation and pattern SD?

   • The mean deviation represents the degree of departure of the whole field's average values, from age-adjusted normal values. The pattern SD represents irregularities within the field, for example, of localised field defects. This can be small in completely normal patients or in those with complete blindness.
