Objective to investigate the effect of different degrees of myopia on light sensitivity in perimetry

Can myopia cause light sensitivity?

Methods: 60 myopic patients with corrected visual acuity ≥ 1.0, IOP < 20 mmHg, cup to disc ratio < 0.3 were divided into three groups: low, medium and high myopia. Each group underwent objective refraction and Humphrey perimetry. The average light sensitivity, average defect, mode standard deviation and the time taken to complete the examination were selected as the test indexes. The results of one eye were randomly selected to compare the differences and similarities of the visual field examination indexes among the groups

Results the visual field light sensitivity decreased with the increase of myopia degree. The average light sensitivity and average defect of high myopia group and moderate myopia group were significantly lower than those of low myopia group (P < 0.01), but there was no significant difference in the mode standard deviation and the time taken to complete the examination among the three groups (P > 0.05)

Conclusion myopia can affect visual field light sensitivity. The higher the degree of myopia, the greater the influence on visual field light sensitivity
