Abstract：Objective To advance our understanding of dark without pressure(DWOP)by investigating its distribution among asymptomatic teenagers who participated in medical selection of Chinese Air Force cadets so as to provide data for optimizing the evaluation criteria of medical selection.Methods Students who participated in the medical selection of Air Force cadets in 2021-2022 were examined by using the ultra-wide angle laser fundus scanning system and optical coherence tomography while the clinical characteristics,such as the incidence of DWOP and the extent of its involvement,were analyzed.Results A total of 744 cadets(1 488 eyes)were enrolled in the study,112 of whom were females(224 eyes)and 632 were males(1 264 eyes).DWOP was detected in 13 eyes of 9 students(0.87％),including 7 males(11 eyes)with a detection rate was 0.87％and 2 females(2 eyes)with a detection rate of 0.89％.In 10 of these eyes(76.92％),the lesions were in the nasal quadrant,and were related to the optic disc in 8 eyes(61.5％).No visual function abnormalities such as visual acuity or visual field were detected in any student.Conclusion DWOP is not a retinal/choroidal pigment change or vitreous/retinal interface change,and there is no direct evidence that DWOP can cause functional changes.During the medical selection of Air Force cadets,cadets whose fundus examinations reveal the presence of DWOP that is not combined with other abnormal fundus changes should not be subject to a failing conclusion.
