  1. OCT: Optical coherence tomography, SS: signal strength, MMFT: mean minimal foveolar thickness, MFT: mean foveal thickness, MCT: mean central thickness, MPT: mean peripheral thickness, MTT: mean total thickness. The outer diameter of the inner, middle and outer rings is 1, 2.22 and 3.45 millimeters respectively. For further definition of macular regions see Figure 1. VA: visual acuity. 1One-sample Student's t-test (test value = 0 for differences between patients’ eyes). 228 patients with bilateral scans were included in this analysis.
