Glaucoma in the far-sighted, who have smaller-than-normal anterior chambers, making physical contact between the iris and trabecular meshwork more likely. Normal-tension glaucoma (also "NTG", "low-tension glaucoma", "normal-pressure glaucoma") is a condition where the optic nerve is damaged although intraocular pressure (IOP) is in the normal range (12-22mm Hg). Individuals with a family history of NTG, those of Japanese ancestry, and those with a history of systemic heart disease are at higher than average risk of developing NTG. The cause of NTG is unknown. Secondary glaucoma refers to any case in which another disease, trauma, drug or procedure causes increased eye pressure,
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
