目的：初步探究视网膜非压迫变白(white without pressure，WWOP)在健康青少年人群中的分布规律，为空军招飞和健康体检提供理论支持。

方法：选取参加2018年空军招收飞行学员医学选拔的高中毕业学员461名和青少年航校入校选拔的初中毕业学员71名作为研究对象。利用超广角激光眼底扫描系统配合直接眼底镜及三面镜检查，对WWOP等眼底病变进行筛查。

结果：本研究纳入的健康青少年人群中WWOP检出率高达2.63%，初中毕业和高中毕业学员WWOP检出率差异无统计学意义(P>0.05)。本研究检出的WWOP病变以颞侧象限为主，尤其以颞下象限多见。高中毕业学员存在WWOP的眼合并其它周边部视网膜变性的比例高达18.18%，较无WWOP眼显著增高。

结论：WWOP在健康青少年人群中并不罕见，病变以颞侧多见，病变区域内合并其它视网膜变性的比例显著增高，体检过程中发现WWOP体征时需对周边视网膜进行仔细检查，避免漏诊、误诊。

METHODS:A total of 461 middle school graduates and 71 junior middle school graduates, who participate in the air force cadets' medical selection, were selected as subjects. The ultra-wide-angle laser fundus scanning system, direct ophthalmoscopy and three-sided mirror were used to check the fundus. The χ² test was used to analyze the incidence and distribution of fundus abnormalities.

RESULTS: The prevalence of WWOP in healthy adolescents was as high as 2.63%. There was no significant difference in the prevalence of WWOP among junior middle school graduates(P>0.05). The lesion was more common in the temporal quadrant, especially the lower temporal quadrant. In the eyes with WWOP in high school graduates, the proportion of retinal degeneration was as high as 18.18%, which was significantly higher than that without WWOP.

CONCLUSION:WWOP is not uncommon in adolescents and is more common in the temporal quadrant. The proportion of retinal degeneration in eyes with WWOP is significantly higher. Thus, in order to avoid missed diagnosis, the surrounding retina should be carefully examined if WWOP was founded in aviation physical examination.
