Stepping into the virtual unknown: feasibility study of a virtual reality-based test of ocular misalignment

Abstract: IntroductionDissociated tests of strabismus provide valuable information for diagnosis and monitoring of ocular misalignment in patients with normal retinal correspondence. However, they are vulnerable to operator error and rely on a fixed head position. Virtual reality headsets obviate the need for head fixation, while providing other clear theoretical advantages, including complete control over the illumination and targets presented for the patient's interaction.PurposeWe compared the performance of a virtua… Show more

“…IVR in HMD is an emerging and very promising visual rehabilitation approach using high-technology devices (52)(53)(54)(55)(56). It is developed to provide perceptual learning with better ecological validity due to virtual reality, greater flexibility due to home-based stimulation protocol, and improved efficiency due to patient-tailored protocols (52,53).…”

“…Besides, several studies on amblyopia and binocular vision using VR technology have also been conducted. A study about the improvement of visual acuity in patients with amblyopia through dichoptic training 2 , showed improvements in stereopsis in patients with intermittent exotropia 3 , and reported the assessment of ocular misalignment of strabismus patients through a dissociative test 13 . We have developed a system using HMD, combining the eye-tracking technology and VR, to measure the angle of strabismus with the principle of cover-uncover and alternate cover tests.…”

“…Li et al 14 reported that the degree of strabismus and stereopsis improved with dichoptic visual training using a VR platform in patients with intermittent exotropia. Nesaratnam et al 20 reported the rst use of a VR headset in assessing ocular misalignment and demonstrated its feasibility as the dissociative test for strabismus.…”
