Normal tension glaucoma Normal tension glaucoma Normal tension glaucoma (NTG) is an eye disease, a neuropathy of the optic nerve, that shows all the characteristics of "traditional" glaucoma except one: the elevated intraocular pressure (IOP) - the classic hallmark of glaucoma - is missing. Normal tension glaucoma is in many cases closely associated with general issues of blood circulation and of organ perfusion like arterial hypotension, metabolic syndrome, and Flammer syndrome. Over many years, glaucoma has been defined by an intraocular pressure of more than 20 or 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number
Henneke horse body condition scoring system strenuous work and also may lack lean muscle. Horses with a very high body condition score carry too much weight, which interferes with stamina and biomechanics. Some studies addressed the relationship of body condition score and endurance performance in endurance races. In a study of the 1990 Purina Race of Champions (a 241-km / 150-mile, 2-day endurance race), it was found that the top-7 finishers of the race (i.e. highly competitive horses) had significantly lower body condition scores and marginally less rump fat than horses eliminated for metabolic criteria (i.e. less competitive horses). By contrast, two studies on the Tevis
