Abstract:

Ocular trauma is an important cause of visual impairment. The ocular trauma score （OTS） formulated by the American association of ocular trauma according to the initial visual acuity level after ocular trauma is helpful to estimate the postoperative visual acuity. Based on this, domestic scholars have studied and established a regression equation to calculate the postoperative visual acuity according to the initial visual acuity after injury. The research results about the relationship between the factors of eye diseases and vision, such as the correlation between the changes of eye structure and vision in myopia, age-related diseases will also have a considerable impact on vision, and have a certain regularity, which has significance in the evaluation of vision after ocular trauma, especially in the identification of injury relationship. In addition to the above, the specific medical process and other influencing factors of intervention after ocular trauma will also have a certain impact on the vision after recovery. In the forensic examination and identification of visual function, it is necessary to comprehensively grasp the relevant information, objectively analyze various influencing factors, and make a comprehensive analysis and evaluation combined with visual electrophysiological test technology.

Key words:

摘要：

 眼外伤是视力损害的重要原因。美国眼外伤协会根据眼外伤后初次视力水平制定的眼外伤评分标准（OTS）有助于估计愈后视力，国内学者据此研究建立了根据伤后初次视力推算愈后视力的回归方程。有关自身眼病因素与视力关系的研究成果，如近视者眼球结构变化与视力之间存在相关性，年龄相关性病变同样也会对视力造成相当的影响且具有一定的规律性，在眼外伤愈后视力的评估、特别是伤病关系鉴定中具有意义。除上述以外，眼外伤后具体的医疗过程及其介入的其他影响因素等，也都会对愈后视力造成一定影响。在视觉功能的法医学检验和鉴定中，有必要全面掌握相关资料，客观分析各种影响因素，并结合视觉电生理的检验技术作出全面分析、综合评定。
