UNASSIGNED:比较近视眼和emmetropes之间的外周对比敏感度(CSF)功能,以揭示直视过程中潜在的肌源性风险。
未经评估:这次观测,横截面,非连续病例研究包括19名近视患者(23.42±4.03岁)和12名近视患者(22.93±2.91岁)的数据,他们接受了中枢和外周快速CSF(qCSF)测量.包括截止空间频率(截止SF)的CSF度量的汇总原木CSF(AULCSF)下的面积,低,中介-,和高空间频率AULCSFs(l-,i-,和h-SFAULCSFs),并在中央凹和15个外围位置的19个SF处记录CS(上,劣等,temporal,和6、12、18和24°偏心的鼻象限,排除18°的生理性暗点),采用3路和4路受试者间方差分析(ANOVA)(α=0.05)进行分析。
UNASSIGNED:三因素方差分析显示,近视眼在6°处显着增加了AULCSF(平均差,0.08;95%CI,0.02-0.13;P=0.007)和12°(平均差,0.09;95%CI,0.03-0.14;P=0.003)。与正常组相比,近视组所有19个SF的LogCS均较高(平均差异,0.02;95%CI,0.01-0.20;P=0.02,平均差差,0.11;95%CI,0.02-0.21;P=0.01)在12°。6°时的h-SFAULCSF(平均差异,1.27;95%CI,0.32-2.22;P=0.009)和i-SFAULCSF在12°(平均差异,5.31;95%CI,4.35-6.27;P<0.001;平均差,1.14;95%CI,0.19-2.10;P=0.02)在近视中高于正常组。
UNASSIGNED:我们发现近视在视网膜的6°旁凹和12°旁凹区域的上下视野位置增加了对比敏感度。在近视的黄斑视野内增加的对比敏感度的观察可能为近视化期间的近视控制提供重要的见解。
UNASSIGNED: Compare peripheral contrast sensitivity functions (CSF) between myopes and emmetropes to reveal potential myogenic risks during emmetropization.
UNASSIGNED: This observational, cross-sectional, non-consecutive case
study included data from 19 myopes (23.42 ± 4.03 years old) and 12 emmetropes (22.93 ± 2.91 years old) who underwent central and peripheral quick CSF (qCSF) measurements. Summary CSF metrics including the cut-off spatial frequency (cut-off SF), area under log CSF (AULCSF), low-, intermediate-, and high-spatial-frequency AULCSFs (l-, i-, and h-SF AULCSFs), and log CS at 19 SFs in the fovea and 15 peripheral locations (superior, inferior, temporal, and nasal quadrants at 6, 12, 18, and 24° eccentricities, excluding the physiological scotoma at 18°) were analyzed with 3-way and 4-way between-subjects analysis of variance (ANOVA) (α = 0.05).
UNASSIGNED: Three-way ANOVA showed that myopes had significantly increased AULCSF at 6° (mean difference, 0.08; 95% CI, 0.02-0.13; P = 0.007) and 12° (mean difference, 0.09; 95% CI, 0.03-0.14; P = 0.003). Log CS at all 19 SFs were higher in the myopia group compared to the normal group (mean differencesuperior, 0.02; 95% CI, 0.01-0.20; P = 0.02 and mean differenceinferior, 0.11; 95% CI, 0.02-0.21; P = 0.01) at 12°. The h-SF AULCSF at 6° (mean differenceinferior, 1.27; 95% CI, 0.32-2.22; P = 0.009) and i-SF AULCSF at 12° (mean differencesuperior, 5.31; 95% CI, 4.35-6.27; P < 0.001; mean differenceinferior, 1.14; 95% CI, 0.19-2.10; P = 0.02) were higher in myopia vs. normal group.
UNASSIGNED: We found myopia increased contrast sensitivity in superior and inferior visual field locations at 6° parafoveal and 12° perifoveal regions of the retina. The observation of increased contrast sensitivities within the macula visual field in myopia might provide important insights for myopia control during emmetropization.
