TMDU Classification of Myopic Traction Maculopathy Based on OCT and Ultra Wide-Field OCT (UWF-OCT)

Myopic traction maculopathy (MTM) is considered a preexisting lesion of macular hole retinal detachment. The diagnosis of MTM is made by the existence of one of the macular lesions; epiretinal membrane, vitreomacular traction, retinal thickening, retinoschisis, macular hole (lamellar or full thickness), and retinal detachment. Tokyo Medical and Dental University (TMDU) classification of MTM is established based on the size and the location of the retinoschisis and the presence of six foveal pathologies. Progression from retinoschisis to retinal detachment is classified into four stages starting with a development of outer lamellar hole.
