简要总结
Investigated the effects of high-frequency multi-band harmonic electromagnetic stimulation on ophthalmic and central retinal artery circulation.
详细描述
This study investigated the effects of prolonged smartphone usage for over 90 minutes on ophthalmic and central retinal artery circulation before and after smartphone use and compared the effects with versus without intervention by high-frequency multi-band harmonic electromagnetic stimulation.

结局指标
主要结局
Peak Systolic Velocity (PSV)
时间窗: At the first visit and after 90 minutes usage of device.
peak systolic velocity (PSV) of the ophthalmic artery (OA) were measured using color Doppler ultrasound of the eye arterial blood flow (EPIQ Elite ultrasound system, PHILIPS).
End Diastolic Velocity (EDV)
时间窗: At the first visit and after 90 minutes usage of device.
end diastolic velocity (EDV) of the ophthalmic artery (OA) were measured using color Doppler ultrasound of the eye arterial blood flow (EPIQ Elite ultrasound system, PHILIPS).
Central Retinal Artery (CRA)
时间窗: At the first visit and after 90 minutes usage of device.
Central Retinal Artery (CRA) were measured using color Doppler ultrasound of the eye arterial blood flow (EPIQ Elite ultrasound system, PHILIPS).
