Abstract
PURPOSETo assess the sensitivity and specificity of superior visual field tests administered in virtual reality (VR) with eye tracking (VR-ET) and without eye tracking (VR0) for the fulfillment of insurance coverage criteria for functional upper eyelid surgery as compared with standard automated perimetry (SAP). METHODSThis prospective cross-sectional study included 78 eyes from 41 patients with ptosis, brow ptosis, and dermatochalasis undergoing functional upper eyelid surgery evaluation. Participants underwent serial superior visual field tests using SAP and VR0 or VR-ET in randomized order. Fulfillment of insurance coverage criteria for blepharoplasty was defined as a 30% increase in the grid seen from the untaped to the taped state. The main outcome measure was the sensitivity and specificity of VR0, VR-ET, and overall VR in meeting insurance coverage criteria as compared with SAP. RESULTSVR had a sensitivity of 84.1% and specificity of 67.6%, with no significant difference between VR0 and VR-ET. SAP agreed on insurance coverage criteria fulfillment with VR0 in 28 (71.8%) eyes and with VR-ET in 32 (82.1%) eyes. Insurance coverage criteria fulfillment rates varied significantly by diagnosis on SAP (p = 0.012) but not VR (p = 0.059). CONCLUSIONSVR may be an alternative to SAP for functional upper eyelid surgery evaluation. Future studies are needed to determine differences in patient satisfaction, testing and waiting time, and test-retest reliability between VR and SAP.
