Lamellar and pseudoholes. a. Lamellar macular hole. OCT 5-mm scan showing a thinned and irregular foveal base (75 µm) with superficial retinal edges separated from deeper layers. The perifoveal retina is of normal thickness (240 µm). b. Macular pseudohole. OCT 5-mm scan showing epiretinal membrane and superficial retinal folds. The foveal pit appears narrow and vertical. The foveolar thickness remains normal (190 µm), while the perifoveal regions are thickened (365 µm).
