间歇性外斜视与近视患者的双眼视功能的比较研究
|
Abstract:
目的：比较间歇性外斜视(IXT)是否合并近视及非IXT近视患者的双眼视功能的差异。方法：收集2023年7月至2024年12月在宁波市眼科医院斜视和小儿眼科门诊就诊的7~12岁患者150例。根据外斜视和等效球镜度分为3组，分为A组(IXT合并近视) 50例，B组(IXT非近视) 50例，C组(近视非IXT) 50例，对各组 双眼视功能参数进行比较。结果：C组的AC/A为(5.25 ± 0.10)，显著高于A组(4.35 ± 0.37)和B组(3.36 ± 0.27) (F = 8.97, P < 0.01)，B组的双眼调节幅度为(8.86 ± 0.19)，显著高于A组(6.77 ± 0.30)和C组(7.62 ± 0.31) (F = 11.97, P < 0.01)，B组的双眼调节反应为(8.51 ± 0.16)，显著高于A组(5.76 ± 0.42)和C组(7.22 ± 0.38) (F = 16.85, P < 0.01)，B组的负相对调节为(2.24 ± 0.05)，显著高于A组(2.01 ± 0.07)和C组(1.99 ± 0.05) (F = 5.43, P < 0.01)，另外，各组之间的正相对调节比较无显著差异(F = 1.76, P > 0.05)。结论：无论是否合并近视，IXT患者均出现AC/A下降；无论是否合并IXT，近视患者的双眼调节幅度、双眼调节反应及负相对调节均出现下降。
Objective: To compare the differences in binocular visual function between patients with intermittent exotropia (IXT) combined with myopia and those without IXT and myopia. Methods: 150 patients aged 7-12 who received treatment for strabismus and pediatric ophthalmology at Ningbo Eye Hospital from July 2023 to December 2024. According to exotropia and equivalent spherical power, the patients were divided into three groups: Group A (50 cases of IXT combined with myopia), Group B (50 cases of IXT non myopia), and Group C (50 cases of myopia without IXT). The study compared the binocular visual function parameters of the three groups. Results: The AC/A of Group C was (5.25 ± 0.10), significantly higher than Group A (4.35 ± 0.37) and Group B (3.36 ± 0.27) (F=8.97, P < 0.01). The binocular accommodation amplitude of Group B was (8.86 ± 0.19), significantly higher than Group A (6.77 ± 0.30) and Group C (7.62 ± 0.31) (F = 11.97, P < 0.01). The binocular accommodation response of Group B was (8.51 ± 0.16), significantly higher than Group A (5.76 ± 0.42) and Group C (7.22 ± 0.38) (F = 16.85, P < 0.01). The negative relative accommodation of Group B was (2.24 ± 0.05), significantly higher than Group A (2.01 ± 0.07) and Group C (1.99 ± 0.05) (F = 5.43, P < 0.01). In addition, there was no significant difference in the positive relative regulation between the groups (F = 1.76, P > 0.05). Conclusion: Regardless of whether myopia is present or not, IXT patients exhibit a decrease in AC/A; Regardless of whether IXT is combined or not, myopic patients show a decrease in binocular accommodation amplitude, binocular
