Abstract
In present, clinically, the VEP has special value in the areas of refraction, infant acuity, diseases of the optic nerve, color blindness, amblyopia and field defects.
VEP reflects the the activity of the visual system from the level of the photoreceptors to the occipital cortex, and it is more directly related to vision than retinoscopy.
Authors studied the VEP change in refractive errors. We used Horizon computer with UTAS-E and the check sizes used were 16X16(50min.), 32X32(25min,)’ 64X64(12.5 min).
One eye was occluded and then lenses of different power were successively placed before the other eye, and a separate VEP was recorded for each lens power.
The result were as follows:
1. Amplitude change according to change of check size in different trial lens powers
1) +3,+4, +5D(64X64): statistically significant decrease
2) -D(except -6D, 32x32): statistically not significant
2. Latency change according to change of check size in different trial lens powers
1) +D(64X64 and +4,+5D(32X32): statistically significant increase
2) -D(64X64) and -10D(32X32): statistically significant increase
3. Amplitude change according to change of trial lens power in different check sizes
1) All check size(+4,+5D) and 64X64 size( + 3D): statistically significant decrease
2) All check size(-D): statistically significant decrease
4. Latency change according to change of trial lens power in different check sizes
1) 32X32 size(+4,+5D) and 64X64 size( + 3, 十4, + 5D): statistically significant increase
