AU: anterior uveitis, OCT: Optical coherence tomography, SS: signal strength. Five macular areas: 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. ¹Two- sample Student's t-test (patients vs. gender-and age matched controls). ²28 patients with bilateral scans and unilateral uveitis were included in this analysis.
