应用脑视觉检查技术评价年龄相关性白内障患者的立体视功能

Evaluation of Stereo Visual Function in Patients with Age-Related Cataract Using Cerebral Visual Inspection Techniques

摘要: 目的：应用脑视觉检查系统评估年龄相关性白内障患者的立体视功能，比较单眼与双眼年龄相关性白内障患者手术前后立体视功能的差异。方法：收集2020年11月至2021年07月深圳市第二人民医院眼科确诊为年龄相关性白内障并需要手术治疗的患者，根据病情程度判断手术眼别，将患者分为单眼白内障组及双眼白内障组，在术前及术后一周利用脑视觉检查的立体视模块，对患者进行立体视功能检查，包括精细立体视、动态立体视、大范围立体视检查，将两组患者的数据进行对比。结果：共35人(50只眼)纳入研究，其中单眼白内障组共20人(20只眼)，双眼白内障组共15人(30只眼)。① 单眼年龄相关性白内障组的最佳矫正视力、大范围立体视、动态立体视及精细立体视均较术前明显改善，差异具有统计学意义(P < 0.05)；② 双眼组年龄相关性白内障组除大范围立体视无明显改变(P = 0.10)，其最佳矫正视力、动态立体视及精细立体视均较术前有明显改善，差异具有统计学意义(P < 0.05)。结论：无论是单眼还是双眼年龄相关性白内障都会导致患者不同程度立体视功能的下降，单眼白内障对立体视影响更大，通过白内障手术治疗，建立视觉平衡，可以有效改善患者的立体视功能，提高患者术后视觉质量。

Abstract: Objective: To evaluate the stereo visual function of patients with age-related cataract by applying the cerebral visual inspection system and to compare the differences in stereo visual function between monocular and binocular patients with age-related cataract before and after surgery. Methods: Patients who were diagnosed with age-related cataract and required surgical treatment in the ophthalmology department of Shenzhen Second People's Hospital from Nov 2020 to July 2021 were collected, and the patients were divided into monocular cataract group and binocular cataract group according to the degree of the disease, and the patients were examined for stereo visual function, including fine stereopsis, dynamic stereopsis, and wide range stereopsis, using the stereo vision module of brain vision examination before and one week after surgery. Results: A total of 35 people (50 eyes) were included in the study, with a total of 20 people (20 eyes) in the monocular cataract group and 15 people (30 eyes) in the binocular cataract group. ① Best-corrected visual acuity, wide-range stereopsis, dynamic stereopsis, and fine stereopsis in the monocular age-related cataract group were significantly improved compared with the preoperative period, with statistically significant differences (P < 0.05). ② The binocular age-related cataract group in both eyes showed significant improvement in best-corrected visual acuity, dynamic stereopsis and fine stereopsis, the difference was statistically significant (P < 0.05),except for the age-related cataract group with no significant change in wide-range stereopsis (P = 0.10). Conclusion: Both monocular and binocular age-related cataracts will lead to different degrees of decreasing stereo vision function in patients. Monocular cataracts have a greater impact on stereo vision, and cataract surgery treatment to establish visual balance can effectively improve patients’ stereo vision function and improve their postoperative visual quality.
