Glaucoma Opaque specks may occur in the lens in glaucoma, known as glaukomflecken. Of the several causes for glaucoma, ocular hypertension (increased pressure within the eye) is the most important risk factor in most glaucomas, but in some populations, only 50% of people with primary open-angle glaucoma actually have elevated ocular pressure. Open-angle glaucoma accounts for 90% of glaucoma cases in the United States. Closed-angle glaucoma accounts for less than 10% of glaucoma cases in the United States, but as many as half of glaucoma cases in other nations (particularly East Asian countries). No clear evidence indicates that vitamin deficiencies cause
Henneke horse body condition scoring system to either being overweight or underweight, respectively. Breeding mares with a body condition score less than five have been linked in research to problems with reproduction. The energy demands of milk production for a foal are very high, so most mares will lose condition while lactating. Also, a mare with a body condition score less than five will have more difficulty conceiving. For these reasons, recommendations are for breeding mares to score between 6 and 7. Higher body condition scores have not been shown to affect reproduction but are unhealthy for the horse. Stallions have the best reproductive success at
