Description

  The present invention relates to a test information input support system and a test information input support program.

  Eye position abnormalities can be roughly divided into oblique and strabismus. The oblique position is distinguished as an eye position shift that can be recovered by the fusion movement, and the oblique view is distinguished as an eye position shift that cannot be recovered by the fusion movement.

  Conventionally, an AC / A ratio (adjustable inward-adjustment ratio, or adjustable convergence-to-adjustment ratio) has been calculated as a method for measuring the degree of eye misalignment. As a method for calculating the AC / A ratio, a calculation method based on the gradient method or the heterophoria method is often used (see, for example, Non-Patent Document 1).

  The Gradient method is a method of giving an adjustment stimulus by fixing the position of an index and changing the lens power placed in front of the eye.

(Far gradient method)
This is a method in which an index is fixed at a distance of 5 m and an eye misalignment while wearing fully corrected glasses is measured by an alternating prism cover test. As the prism, a prism bar is usually used, but the use of a rotary (double) prism can measure the positional deviation more finely. The concave lens power is gradually increased to S-1.00D, S-2.00D, and S-3.00D to the complete correction lens power, and the eye position deviation is measured each time.

(Near Gradient method)
An alternate prism cover, similar to the far gradient method, is used to fix eye misalignment under lens wearing with a fixed index near 33.3 cm and adding S + 3.00D (strictly + 3.33D) to the complete correction power. Measure with a test. The concave lens power is gradually increased to S-1.00D, S-2.00D, and S-3.00D, and the positional deviation is measured each time.

And the calculation of the AC / A ratio by the Gradient method when the measurement results as described above, for example, the following measurement results are obtained,
・ Position shift without concave lens: 4Δ inner oblique (+ 4Δ)
Eye position deviation at S-1.00D load: 7Δ inner slope (+ 7Δ)
Eye position deviation at the time of S-2.00D load: inner slope of 12Δ (+ 12Δ)
-Eye position deviation at the time of S-3.
Eye position deviation at S-4.00D load: inner slope of 20Δ (+ 20Δ)
AC / A ratio between no concave lens and S-1.00D load is
AC / A = (7-4) / (1.00-0) = 3.0Δ / D
The AC / A ratio between S-1.00D load and S-2.00D load is
AC / A = (12−7) / (2.00−1.00) = 5.0Δ / D
AC / A ratio between no concave lens and S-4.00D load is
AC / A = (20-4) / (4.00-0) = 4.0Δ / D
And calculated.

(Heterophoria method)
In the Heterophoria method, first, fully corrected spectacles are worn on the subject, and the interpupillary distance (a (cm)) is measured. For example, the eye position shift (fΔ) at the time of fixation of the index 5m away is measured by the alternating prism cover test, and then the eye position shift (nΔ) at the time of fixation near 33.3 cm is also measured by the alternating prism cover test. , The AC / A ratio is
AC / A ratio = (nΔ−fΔ) / 3D + a
Is calculated as
