Abstract

Purpose : To assess completion rate and correlation of virtual reality visual field (vFA) home monitoring in a pilot sample of experienced visual field test takers with glaucoma.

Methods : 9 Adults (mean age 60.6 years) with an established diagnosis of glaucoma were prospectively enrolled in this ongoing pilot study from a single institution. After an in-office training, participants were sent home with the VisuALL Field Analyzer (vFA; Olleyes Inc. Summit, NJ) for perimetry and the iCare Home Rebound Tonometer (TA022, Icare Oy, Vanda, Finland) for intraocular pressure (IOP) measurements. They were instructed to collect 4 IOP measurements per eye per day for 3 days, and 1 perimetry test per day over the same 3 days. The mean deviation (MD) and pattern standard deviation (PSD) values from the 3 at-home vFA tests were averaged and compared to the most recent in-office Humphrey Field Analyzer (Carl Zeiss Meditec, Dublin, CA) visual field (HVF) values using SPSS V.28 (IBM SPSS Statistics) to determine the Spearman correlation coefficient. The intraclass correlation (ICC) for MD and PSD values were also calculated for the 3 vFA perimetry tests taken at home. IOP in-clinic and at-home were compared using the Pearson correlation coefficient.

Results : Of 9 participants enrolled, 6 (10 eyes) successfully completed the protocol. 1 participant had difficulty using the devices and 2 were lost to follow-up. The Spearman correlation coefficient of the MD and PSD from vFA relative to the HFA was 0.758 (p=0.011) and 0.867 (p=0.001), respectively. ICC values for the 3 vFA perimetry tests taken at home were 0.918 (p<0.001) for MD and 0.955 (p<0.001) for PSD. The average of the last 5 IOP measurements in-clinic compared to the average of all the at-home measurements yielded a Pearson correlation coefficient of 0.954 (p<0.001).

Conclusions : Home monitoring with vFA and rebound tonometry is feasible and may provide clinically useful data to help manage glaucoma patients remotely.
