Comment on macular full-thickness and lamellar holes in association with type 2 idiopathic macular telangiectasia.

摘要

The article by Charbel Issa et al is an interesting report on the association of type 2 idiopathic macular telangiectasia (IMT) with both full-thickness and lamellar macular holes (MHs). The aetiology of IMT is unknown, but possibilities include chronic leakage from hyper-permeable capillaries and ischaemia. The authors hypothesise that MHs in IMT are caused by tissue loss consequential to these factors, with secondary draping of an as yet undefined membrane, possibly ILM, over these areas rather than the accepted concept of epiretinal tractional forces that result in idiopathic MHs.
