Abstract
High-resolution spectral domain optical coherence tomography (SD-OCT) is the standard examination for assessment of lamellar macular holes (LMH). According to the current SD-OCT classification of LMHs, they are characterized by (1) an irregular foveal contour, (2) a defect in the inner fovea, and (3) a separation of inner retinal layers from outer retinal layers of the fovea leading to an intraretinal splitting with loss of retinal tissue. The article aims to give an overview on the current knowledge of retinal imaging in LMH diagnostics and clinical course of disease. This review is based on current literature and analyses of data from different case series from the Department of Ophthalmology, Ludwig-Maximilian University Munich, Germany. In eyes with LMH, a homogenous atypical, hyporeflective epiretinal tissue has been described in addition to conventional tractional epiretinal membranes (ERM). By SD-OCT, this named lamellar hole-associated epiretinal proliferation (LHEP) does not show common signs of traction and is characterized as a thick homogenous layer of moderately reflective material. LHEP has been demonstrated to be related to the occurrence of photoreceptor layer defects, enlargement of LMH diameter and poor visual acuity. The correlation of SD-OCT and en-face OCT can help to identify LMH subgroups and morphology progression early on. FAF enables detection of structural changes at a subclinical stage without visual deterioration. With regard to a high variability of intraretinal changes in LMHs and epimacular fibro-cellular proliferation, the current classification of LMH should be discussed and re-evaluated.
