Define the term -Aqueous Movement and Outflow

There are two movements of the aqueous humour that occur-thermal flow and bulk flow. Thermal flow is, an internal circulation of the aqueous fluid in the anterior chamber. This occurs because of a difference in temperature between the cornea (cooler) and iris (warmer). In bulk flow, the aqueous humour moves from the ciliary epithelium in the posterior chamber and continues through the drainage channels at the anterior chamber angle and then through the episcleral veins. This can occur through a pressure dependent path or a pressure independent pathway. The pressure dependent pathway goes through the small pores (Canal of Schlemm) of the trabecular network (called the "Conventional Outflow"), which accounts for 80-90 per cent of the total outflow. In the independent pathway the aqueous \humour drams through the uveoscleral outflow (also called the "Unconventional Outflow") channel.
