On performing refraction using a plane mirror on a patient who has a refractive error of –3 D sphere with –2 D cylinder at 900 from a distance of 1 metre under no cycloplegia, the reflex would be seen to move –
assistant
The correct answer is  This patient has a refractive error of

i) - 3D in one meridian
ii) - 2D in meridian 90° to the previous one

So, the patient has a refractive error which is different in different media → Patient is having astigmatism, especially compound myopic astigmatism as myopia is present in both the media.
As myopia > 1D is there in both vertical and horizontal axes, the pupillary real reflex will move against the movement of retinoscope in both axes.
