摘要

背景:自动瞳孔测量装置可提供有关瞳孔功能的重要信息。在维生素B12缺乏症(VB12D)中观察到神经系统表现,如自主神经功能障碍和眼科疾病。目的:应用瞳孔测量仪评估小儿VB12D患者的静态瞳孔功能。方法:选取40例患VB12D的儿童和40例健康儿童作为对照组。测量是在静态条件下用自动瞳孔测量仪进行的。静态测量是在暗、中、光强度下进行的。通过静态测量分析患者与对照组之间的差异。结果:观察暗、中、光条件下患者与对照组的瞳孔直径,中、光条件下差异有统计学意义。中观条件下:VB12D组平均瞳孔直径为5.92±0.69 mm,对照组平均瞳孔直径为5.18±0.91 mm (P = 0.003)。在光敏条件下,VB12D组平均瞳孔直径为5.13±0.77 mm,对照组平均瞳孔直径为4.53±0.96 mm (P = 0.001)。暗斑条件下,VB12D组平均瞳孔直径为6.46±0.68 mm,对照组平均瞳孔直径为6.37±0.93 mm。患者与对照组在暗沉条件下的测量差异无统计学意义(P = 0.63)。结论:小儿VB12D患者在光、中视状态下的瞳孔直径明显大于健康儿童。结果表明,患有VB12D的儿童存在自主神经系统功能障碍,特别是当副交感神经系统受到负面影响时。服用VB12D的儿童瞳孔收缩减少。瞳孔肌收缩功能下降。维生素b12缺乏儿童在光性和中视性条件下瞳孔较大。

Evaluation of Static Pupillary Parameters in Pediatric Patients with Vitamin B12 Deficiency.

Background: Automatic pupillometry device enables important information about pupillary function. Neurological manifestations such as autonomic dysfunction and ophthalmological disorders are observed in vitamin B12 deficiency (VB12D).

Aim: To assess the static pupillary functions using a pupillometry device in pediatric patients with VB12D.

Methods: The study included 40 children with VB12D and 40 healthy children in the control group. The measurements were made with an automated pupillometry under static conditions. The static measurements were performed at scotopic, mesopic, and photopic light intensities. The differences between the patient and control groups were analyzed with static measurements.

Results: Pupillary diameters of the patient and control groups under scotopic, mesopic, and photopic conditions were observed and there was a statistically significant difference under the mesopic and photopic conditions. Under mesopic conditions: The mean pupil diameter was found to be 5.92 ± 0.69 mm in the VB12D group and 5.18 ± 0.91 mm in the control group (P = 0.003). Under photopic conditions, the mean pupil diameter was found to be 5.13 ± 0.77 mm in the VB12D group and 4.53 ± 0.96 mm in the control group (P = 0.001). Under scotopic conditions, the mean pupil diameter was 6.46 ± 0.68 mm in the VB12D group and 6.37 ± 0.93 mm in the control group. There was no statistically significant difference between the patient and control groups in the measurements under scotopic conditions (P = 0.63).

Conclusion: Pediatric patients with VB12D have significantly larger pupil diameters in photopic and mesopic conditions than healthy children. The results suggest that there is an autonomic system dysfunction in children with VB12D, especially when the parasympathetic system is negatively affected. Pupillary contraction is reduced in children with VB12D. Decreased pupillary myosis function is observed. Pupillary size is larger in vitamin B12-deficient children under photopic and mesopic conditions.
