Lamellar Macular Holes: The Role of Microperimetry in Functional Assessment

Table 3

Statistical analysis of demographical characteristics and functional and morphological parameters, considered for all patients and according to tractional and degenerative LMH groups. LogMAR best-corrected visual acuity; mean central and total retinal sensitivity (mCRS and mTRS) in dB; LMH diameters and central foveal thickness (CFT) in microns.
