Abstract

Purpose: To compare the Heidelberg Edge Perimeter (HEP) and the Octopus Visual Field (OVF) Analyzer in the detection of visual field defects in patients with glaucoma. Preliminary studies suggest that the HEP may detect glaucomatous changes earlier than current standard perimetric testing.

Methods: Visual fields were obtained on 45 eyes (30 patients) with glaucoma using the G top strategy on the OVF Analyzer (Haag-Streit, Koeniz, Switzerland) and the Standard Automated Perimetry strategy with the advanced staircase thresholding algorithm on the HEP (Heidelberg Engineering, Heidelberg, Germany). All patients were greater than 18 years of age, had a best-corrected visual acuity of 20/40 or better, refraction within ± 5.0 diopters spherical correction and ± 3.0 diopters cylindrical correction. Patients were identified as having characteristic glaucomatous disc damage and visual field defects, which were verified by a glaucoma specialist. All patients had reliable visual fields (indices <33%). The absolute values of the HEP and OVF mean deviation (MD) and pattern standard deviation (PSD) were compared.

Results: Forty-five eyes of 30 patients were included. The mean age was 72.3 ± 10.2 years, 14 were male and 16 were female. The mean MD and PSD values from OVF were 10.36 ± 6.35 and 4.75± 2.30, respectively. The mean MD and PSD values from HEP were 7.57 ± 6.71 and 5.33 ± 3.21, respectively. Pearson correlation coefficients showed high correlations for both the MD and PSD values: MD HEP vs. OVF: r=0.86, r2=0.76, P<0.0001, PSD HEP vs. OVF: r=0.83, r2=0.60, P<0.0001.

Conclusions: Global index values between the HEP and OVF are closely correlated. This suggests that the HEP provides similar detection of glaucomatous changes in patients with glaucoma. Studies comparing the spatial defects detected on HEP and OVF are underway. 1. Mulak et al. Adv Clin Exp Med. 2012 Sep-Oct;21(5):665-70. 2. King et al.
