Presentation Description :
Inside the eye, the ciliary processes continually produce aqueous humor, a vital fluid needed to maintain the health of the avascular tissues in the anterior segment. This fluid must drain out through the outflow pathways at the same rate that it is produced but it must do this through tissue with carefully regulated resistance in order to maintain a healthy intraocular pressure. In healthy eyes aqueous humor is secreted at a variable rate, being slower at night than during the day and slower as one ages. In most diseases, such as the ones that affect IOP, aqueous production does not change. In inflammatory conditions, it slows. Drainage, on the other hand varies significantly in diseases that affect IOP, such as in glaucoma, ocular hypertension and several syndromes. Our current knowledge of the aqueous humor dynamics in health and disease continues to expand with new ideas on aging and ethnic variations.
