Table 3 Subgroup analysis of near visual acuity (NVA) ≤0.15 vs. >0.15 LogMAR of the digital test LogMAR: logarithm of the minimum angle of resolution. CSR: central serous retinopathy, PXE: Pseudoxanthoma elasticum. *Other macular diseases include diabetic retinopathy, hemi-central retinal vein occlusion due to hypertensive retinopathy and hemi-retinal vein occlusion [1]. Measured by the conventional Amsler chart
