Abstract

Purpose : To investigate whether measurements of the inner macular thickness can indicate foveal visual function in open-angle glaucoma (OAG).

Methods : Sixty-two eyes from 62 OAG patients (mean age; 56.2±10.2 yr-old and mean MD value of HFA24-2; -14.23±8.08dB) were included into the study. The macular region was separated into 5 areas corresponded to the clusters of HFA10-2 test points (Figure 1). The thickness of the retinal nerve fiber layer (RNFL), ganglion cell layer(GCL)+inner plexiform layer (IPL) and RNFL+GCL+IPL (GCC) in each 5 area were measured with retinal ganglion cell displacement by a SD-OCT (3D OCT-2000, Topcon, Tokyo, Japan). And then we evaluated the correlation between the thickness in each area and foveal sensitivity threshold.

Results : In the central area 1, the RNFL, GCL+IPL as well as GCC were strongly correlated with foveal sensitivity threshold (R=0.711, 0.725, and 0.748, respectively, p<0.001). The upper arcuate area 2 and the lower arcuate area 4 associated weak to moderate correlations between the RNFL, GCC and foveal sensitivity threshold (R=0.338 to 0.440, P<0.01). No statistical correlations were detectable in the most peripheral areas 3 and 5.

Conclusions : Measurements of the RNFL, GCL+IPL, and GCC particularly in the central area 1, just corresponded to the papillo-macular bundles, might be an indicator to evaluate foveal visual functions including sensitivity threshold and possibly visual acuity in OAG.
