Abstract
Purpose :
Recent studies demonstrate the noninferiority of virtual reality (VR) perimetry compared to the Humphrey Field Analyser (HFA). This study aims to quantify the efficacy of VR perimetry in the unique patient population of John H. Stroger Jr. Hospital of Cook County (CCHHS). The ophthalmology clinic at CCHHS serves a high volume of majority Hispanic and African-American patients, a significant proportion of which are uninsured or Medicaid recipients, with many facing socioeconomic barriers to healthcare access.
Methods :
Visual fields of 25 eyes in 13 glaucoma patients were determined using the Micro Medical Devices VF2000 headset and HFA. The two testing methods were used sequentially in random order. Paired two-tailed t-test were used to compare mean deviation (MD), pattern standard deviation (PSD), false negatives (FN), false positives (FP), test duration, and average decibel per Glaucoma Hemisphere Test (GHT) sector, between each testing method.
Results :
The mean test duration of the VR headset (3.88±1.23 minutes) was significantly shorter (p = 0.013) than HFA (4.45±1.6 minutes). Though the number of FN was significantly higher using the VR headset than HFA (p = 0.0064), the difference in FP was not statistically significant (p = 0.285). The difference in MD and PSD between HFA and VR test groups was also nonsignificant (p=0.7673 and p = 0.8935 respectively). Average decibel per GHT sector between HFA and VR test groups was not statistically significant (p<0.05).
Conclusions :
VR perimetry demonstrates thorough noninferiority within a racially and ethnically diverse glaucoma patient population, and presents itself as a viable option to cut costs and improve flow in a high-volume clinic setting.
