CASE REPORTS We present two cases of blunt ocular trauma with clinical findings and complementary tests compatible with traumatic optic neuropathy (TON), and progression to sectorial optic atrophy. DISCUSSION TON have an essentially clinical diagnosis, and in the last few years has been treated with high doses of intravenous steroids, based on weak evidence of the benefit of the steroids in c...

A new approach to the Kolmogorov-Arnold-Moser theory concermng the existence of invariant ton having prescnbed frequencies îs presented It îs based on the Lagrangian formahsm m configuration space instead of the Hamiltonian formahsm in phase space used in earher approaches In particular, the construction of the invariant ton avoids the composition of infinitely many coordinate transformations T...

The social cost of carbon (SCC) is a central concept for understanding and implementing climate change policies. This term represents the economic cost caused by an additional ton of carbon dioxide emissions or its equivalent. The present study presents updated estimates based on a revised DICE model (Dynamic Integrated model of Climate and the Economy). The study estimates that the SCC is $31 ...

toxic optic neuropathy (ton) is a group of medical disorders which can be defined by visual impairment due to optic nerve damage by a toxin. the exposure to a toxic substance can occur at the workplace, with ingestion of materials/ foods containing a toxin, or the use of systemic medications. ton is a disease entity which is not only under-diagnosed, but also often diagnosed at a stage when rec...

purpose: to evaluate the role of transvitreal optic neurotomy (ton) in the management of non-arteritic anterior ischemic optic neurotomy (naion). methods: sixteen eyes of 16 patients with recent onset naion (less than six weeks duration) were included in this single-masked randomized controlled trial. the patients were randomized to ton (8 eyes) versus observation alone (8 eyes). pre- and posto...
