A macular hole is defined as a full-thickness defect of the foveal retina from the internal limiting membrane to the outer segment of the photoreceptor layer. Although the first reported case, described by Knapp in 1869 (Mireskandari et al. 2004), was ascribed to a traumatic aetiology, practitioners have recognised that this condition occurs more commonly in patients without any antecedent injury. As such, macular holes are characterised as idiopathic full-thickness macular holes to differentiate them from their traumatic counterpart.
