摘要

目的:本研究旨在评估远视性屈光参差性弱视患者黄斑色素光密度(MPOD)评分,并用单波长眼底反射仪将其与同行和对照眼进行比较。方法:这项横断面研究纳入了33名年龄在12-40岁的远视性屈光参差性弱视患者。对照组包括36名远视儿童和42名正视儿童,年龄与患者相匹配。测量研究组和对照组之间的中央黄斑厚度(CMT)、MPOD、轴长(AL)、最佳矫正视力和屈光误差。结果:诊断为远视性屈光参差性弱视的眼睛与其他眼睛以及远视和正视眼相比,MPOD的平均值和最大值(max)得分显著较高(结论:远视性屈光参差性弱视的MPOD降低,这可能是由于视觉刺激较少导致屈光参差型弱视的中央凹发育和微结构恶化所致。

Evaluation of Macular Pigment Optical Density in Eyes with Hyperopic Anisometropic Amblyopia Using Fundus Reflectometry.

Evaluation of Macular Pigment Optical Density in Eyes with Hyperopic Anisometropic Amblyopia Using Fundus Reflectometry.

Evaluation of Macular Pigment Optical Density in Eyes with Hyperopic Anisometropic Amblyopia Using Fundus Reflectometry.

Objectives: This study aimed to evaluate the macular pigment optical density (MPOD) scores in eyes with hyperopic anisometropic amblyopia and compare those with their fellow and control eyes using one-wavelength fundus reflectometry.

Methods: This cross-sectional study enrolled 33 patients diagnosed with hyperopic anisometropic amblyopia aged 12-40 years. The control group consisted of 36 hyperopic and 42 emmetropic children, age-matched to the patients. Central macular thickness (CMT), MPOD, axial length (AL), best-corrected visual acuity, and refraction errors were measured between the study group and the control group.

Results: Eyes with the diagnosis of hyperopic anisometropic amblyopia had significantly higher mean and maximum (max) MPOD scores compared with their fellow eyes as well as hyperopic and emmetropic eyes (p<0.001 for all). The mean AL in eyes with hyperopic anisometropic amblyopia was statistically shorter than that in hyperopic and emmetropic controls (p=0.027, p<0.001, respectively). The mean CMT was found to be thicker in eyes with hyperopic anisometropic amblyopia when compared to their fellow eyes, as well as hyperopic and emmetropic controls, eventhough there was no significant difference was found among the four groups (p=0.052). The mean MPOD levels were significantly correlated with the difference in CMT (r=-0.21, p=0.032), and logMAR visual acuity scores (r=-0.44, p<0.001) in the hyperopic anisometropic amblyopia group.

Conclusion: The present study indicates that the MPOD is reduced in eyes with hyperopic anisometropic amblyopia. This reduction may be due to less visual stimulus-induced deterioration of foveal development and microarchitecture in anisometropic amblyopic eyes.
