Glaucoma "closed-angle glaucoma", "primary angle-closure glaucoma", "acute glaucoma") the iris bows forward and causes physical contact between the iris and trabecular meshwork, which blocks the outflow of aqueous humor from within the eye. This contact may gradually damage the draining function of the meshwork until it fails to keep pace with aqueous production, and the intraocular pressure rises. The onset of symptoms is sudden and causes pain and other symptoms that are noticeable; it is treated as a medical emergency. Unlike open-angle glaucoma, angle-closure glaucoma is a result of the angle between the iris and cornea closing. This tends to occur
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
