Abstract:
AIM: To investigate the refractive distribution and analysis risk factors for aircrew ametropia.
METHODS: The number of 49 cases with ametropia from 1031 aircrew during May 2013 to May 2014 were reviewed. Various types of refraction composition, age, type, position, time of flight with the subjective assessment of aircrew were analyzed and compared.
RESULTS:Of 49 cases, 43 cases (88%) were myopia, 6 cases ( 12%) were hypermetropia. , Detection rates were higher in age over 50 years aircrew and flight time more than 3000h. Detection rates were lower in self-conscious symptom heavy aircrew, fighter aircrew and good habit of using eyes.
CONCLUSION: The myopia incidence in aircrew with age >50 years and long flight time is higher, than that of fighter pilots and good habit of using eyes. We should pay attention to the increasing late-onset myopia of aviators and habit of using eyes, work intensity and time of using eyes about aircrew.
