Abstract

Purpose: To investigate lamellar macular hole (LMH) and macular pseudohole (MPH) using a combination of en face and radial B-scan OCT. Design: Retrospective observational case series. Methods: SETTING: Institutional study. PATIENT POPULATION: En face and radial B-scan OCT images of 63 eyes of 60 patients diagnosed with LMH or MPH based on an international classification were reviewed. OBSERVATION PROCEDURES: Cases were classified using en face images based on the presence/absence of epiretinal membrane (ERM), retinal folds, parafoveal epicenter of contractile ERM (PEC-ERM), and retinal cleavage. We compared the en face imaging–based classification system with the international classification system using radial B-scan images. We quantitatively evaluated visual function and macular morphology. MAIN OUTCOME MEASURES: Characterization of multimodal OCT-based subtypes of LMH and MPH. Results: All cases showed ERM and were classified into 4 groups. In the first group, which lacked retinal folds and showed significantly lower visual acuity than the other groups, 81% of eyes had degenerative LMH. In the second group, which lacked PEC-ERM and retinal cleavage and showed significantly lower retinal fold depth, all eyes had MPH. The third group, in which 95% of eyes had symmetric tractional LMH, included eyes with retinal cleavage but without PEC-ERM, and this group showed higher circularity of the foveal aperture and cleavage area than the group with both these features, in which all eyes had asymmetric tractional LMH. Conclusions: Multimodal OCT enables classification of LMH and MPH based on pathologic conditions. Retinal traction in particular may be useful for determining treatment methods.
