ABSTRACT
@#AIM:
To assess the halo size and contrast sensitivity on different levels of myopia and to analyze their correlation.<p>METHODS:
Screening total 156 myopic patients aged 18 to 39 years old included in our hospital from March 2018 to March 2019. There were 49 subjects in high myopia group(SER>-6.00D), 54 in medium myopia group(-3.00D<SER≤-6.00D)and 53 in low myopia group(SER≤-3.00D). Size of halo disk, and contrast sensitivity of 0.6, 1.1, 2.2, 3.4, 7.1, 14.2c/d were measured by vision monitor of MetroVision Monpack One. <p>RESULTS:
The size of glare halo in high myopia group was 106.27±25.89arc min, and 103.81±31.41arc min in medium myopia group, 102.87±32.24arc min in low myopia group, and there was no significant difference among three groups(<i>F</i>=0.297, <i>P</i>=0.825). There was no significant difference among three groups on contrast sensitivity under any different spatial frequencies(<i>P</i>>0.05). Correlation analysis showed a significant negative relationship between glare halo radius and contrast sensitivity at the c/d of 1.1, 2.2, 3.4, 7.1(<i>r</i>s=-0.302, <i>r</i>s=-0.308, <i>r</i>s=-0.383, <i>r</i>s=-0.257, all <i>P</i><0.01), and no significant correlation was detected between halo radius and SER(<i>P</i>>0.05).<p>CONCLUSION:
Glare halo size had no relationship with SE but mid-frequency contrast sensitivity.
