ABSTRACT

@#AIM: To investigate the prevalence on peripheral retinal degeneration and to provide theoretical support for the medical examination of civil aviation pilots recruitment. <p>METHODS: Two thousand four hundred and fifty prospective flight students(Four thousand nine hundred eyes)who received medical examination in Civil Aviation General Hospital from February 2018 to May 2019 were divided into three groups according to diopter after fully mydriatic with tropicamide phenylephrine eye drops(Group A: +3.00 to <-0.50D, Group B: -0.50 to <-3.00D, Group C: -3.00 to -4.50D). The prevalence of peripheral retinal degeneration in each eye was examined, and the results were statistically analyzed. <p>RESULTS:There were five hundred and seventy five students with different types of peripheral retinal degeneration in 2 450 checked students, the prevalence was 23.5%. There was statistical difference in the prevalence of peripheral retinal degeneration in different diopter groups(χ2=65.386, <i>P</i><0.01). There was statistical difference in the prevalence of different types of peripheral retinal degeneration(χ2=351.276, <i>P</i><0.01). There was statistical difference in the prevalence of peripheral retinal degeneration in different parts(χ2=563.712, <i>P</i><0.01). <p>CONCLUSION: Peripheral retinal degeneration is not rare in civil aviation recruitment. The prevalence increases with the progression of myopia, and the lesions are mostly in bitamporal quadrant. It is suggested to identify according to different types.

ABSTRACT

@#AIM: To investigate the epidemiological character of white without pressure(WWOP)in the healthy adolescents by fundus examination and provide theoretical support for air force recruitment and health examination. <p>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 χ<sup>2</sup> test was used to analyze the incidence and distribution of fundus abnormalities.<p>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(<i>P</i>>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. <p>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.
