Mean values for each of the measures of vision are shown categorised by macular lesion component and the presence or absence of that component in the macular. Distance and near visual acuity is shown in logMAR and contrast sensitivity in log contrast units. (DVA = distance visual acuity NVA = near visual acuity CS = contrast sensitivity CNV = choroidal neaovascular membrane.)
