[Comment on the therapeutic value of optic atrophy].

Optic disc pale is a typical sign of optic atrophy and is often improperly remarked an "totally visual function damaged and without any therapeutic value". However, increasing evidences showed that there is considerable potential for vision restoration and recovery by appropriately stimulating the undamaged visual pathway through different means, medications and low vision rehabilitation techniques. Correct recognition the therapeutic value of optic atrophy is undoubtedly valuable for visual function improvement. We encourage continuously developing new way or tool to rescues or preserve the residual vision of optic atrophy.
