Increased aqueous humor production
WebIncreased ocular pressure can occur from overproduction of aqueous humour, the clear fluid in the chambers of the eye, or inadequate drainage of this fluid. Glaucoma is the leading cause of blindness in the world. And while over 2 million Americans have been diagnosed with this disease, many more are unaware that they have glaucoma. WebExcessive Aqueous Humor Production Located behind the iris, or the coloured part of the eye, is a structure known as the ciliary body. This structure is responsible for the production of aqueous humor. This clear fluid is similar to blood plasma in composition and contains water and a small amount of sugar, vitamins, proteins and other ...
