摘要

Purpose/Aim: We aimed to investigate the effect of monocular blur on the binocular visual field. Materials and Methods: A total of 13 healthy young volunteers participated in this study. The mean subjective refractive error of the dominant eye (DE) was -3.33 ± 1.65D, and the non-dominant eye (NDE) was -3.15 ± 2.84D. The DE was determined by using the hole-in-the-card test. The visual field was examined by the Humphrey Visual Field Analyzer using the 30-2 SITA Standard program. The visual field was measured while wearing soft contact lens under three conditions;① both eyes: near vision correction;② DE: near vision correction +3.00D added, NDE: near vision correction;and ③ DE: near vision correction, NDE: near vision correction +3.00D added. The foveal threshold, mean deviation (MD), and pattern standard deviation (PSD) values were investigated. Results: The foveal threshold value (dB) at ①, ②, and ③ was 41.2, 37.8, and 38.1, respectively. The values at ② and ③ were both significantly lower than that at ① (p Conclusion: These results suggest that monocular blur reduced the sensitivity within the binocular visual field.
