本研究调查了无人工耳蜗植入的深度耳聋儿童的周边视觉（至少30度偏心固定）的发展，并将其与年龄匹配的听力控制以及聋人和听力成人数据进行了比较。使用一种新的专门为儿科设计的静态视野检查方法对5至15岁的耳聋和听力正常儿童进行评估。治疗组（N = 25）为14名女性和11名男性，平均年龄9.92岁（范围5-15岁）。听力正常组64例，女34例，男30例，年龄5-15岁，平均9.13岁。所有参与者的双眼视力均良好（< 0.200 LogMAR）。在30度和85度之间的偏心率下，对简要呈现的三种光强度的LED刺激的检测精度和反应时间进行测量，同时保持对中心目标的固定。研究发现，5至10岁的聋哑儿童周边视力下降。Deal儿童（5-10岁）对所有刺激的反应时间较慢，检测和准确报告远边缘昏暗刺激的能力降低。13-15岁的聋人青少年表现出更快的反应时间，所有周边刺激相比，听力控制。青少年的结果是一致的聋人和听力成人的表现，其中聋人成年人也表现出显着更快的反应时间比听力控制。在11-12岁时，聋人和听力正常的儿童在这项任务上的周边视觉表现在反应时间和检测准确性方面都达到了成年人的成熟水平。
This study investigated peripheral vision (at least 30 degrees eccentric to fixation) development in profoundly deaf children without cochlear implantation, and compared this to age-matched hearing controls as well as to deaf and hearing adult data. Deaf and hearing children between the ages of 5 and 15 years were assessed using a new specifically paediatric designed method of static perimetry. The deal group (N = 25) were 14 females and 11 males, mean age 9.92 years (range 5-15 years). The hearing group (N = 64) were 34 females, 30 males, mean age 9.13 years (range 5-15 years). All participants had good visual acuity in both eyes (< 0.200 LogMAR). Accuracy of detection and reaction time to briefly presented LED stimuli of three light intensities, at eccentricities between 30 degrees and 85 degrees were measured while fixation was maintained to a central target. The study found reduced peripheral vision in deaf children between 5 and 10 years of age. Deal children (aged 5-10 years) showed slower reaction times to all stimuli and reduced ability to detect and accurately report dim stimuli in the far periphery Deaf children performed equally to hearing children aged 11-12 years. Deaf adolescents aged 13-15 years demonstrated faster reaction times to all peripheral stimuli in comparison to hearing controls. Adolescent results were consistent with deaf and hearing adult performances wherein deaf adults also showed significantly faster reaction times than hearing controls. Peripheral vision performance on this task was found to reach adult-like levels of maturity in deaf and hearing children, both in reaction time and accuracy of detection at the age of 11-12 years.
