DIVISION DESCRIPTION TEST METHOD
Aniseikonia test
The test is for checking
aniseikonia of right or left eye
using a polarizing filter.
1. Show aniseikonia test type.
2. Let a patient wear Red/Green glasses (right eye =
red filter, left eye = green filter). The patient sees
fixation target and “]” in a right eye and fixation
target and “[” in a left eye.
3. Ask a patient if he can see borders that have in
between interval. Also asking if a left and a right
border are alike or which one is shown smaller than
the other.
The patient's binocular conditionⓐ
is left > right and right eye < left
eye.
The patient's binocular conditionⓑ
is left < right and right eye > left
eye.
4. The reason of aniseikonia is heteropsia (when
diopter's difference of both a right and a left eye is
too big).
And if the result were an axial heteropsia,glasses
would be prescribed and if a refractive heteropsia,
contact lenses prescribed.
