Novel Multi-functional Visual Simulator for Detecting Ocular Changes Due to Structural-functional Anomalies

Ophthalmic medical equipment is indispensable in the diagnosis and control of eye diseases. However, no existing equipment can monitor the changes in eye’s structure and functions due to eye diseases restricted to specific region in the eyeball.

This novel visual simulator projects some images on specific regions of the subject’s retina, providing controlled stimuli to the eye. Meanwhile, the device records the eye’s reaction to the stimuli and creates a map of the patient’s visual field sensitivity including analyses of eye acuity, eye movements and the retina. It greatly facilitates the measurement of the structural and psychophysical conditions of different regions of the eye for diagnosis of retinal regions at risk and establishment of clinical strategies. It can be used to closely monitor the progression of specific eye diseases and provide customized optical parameters when prescribing ophthalmic optical aids.
