Behind the cornea is the iris – the coloured part of the eye – with the pupil forming a hole in its centre. The space between the cornea and the lens is filled with a clear fluid, called aqueous humour; this fluid maintains the pressure in the eye (the intraocular pressure).Click to see full answer. Also question is, what maintains intraocular pressure?Intraocular Pressure. IOP is maintained primarily by changes in the aqueous humor outflow resistance, which is thought to reside predominantly within the cribriform or juxtacanalicular (JCT) region of the trabecular meshwork (TM) and the inner wall of Schlemm’s canal (SC).One may also ask, how does the eye regulate pressure? The front part of the eye is filled with a clear fluid called intraocular fluid or aqueous humor, made by the ciliary body. The fluid flows out through the pupil. It is then absorbed into the bloodstream through the eye’s drainage system. Proper drainage helps keep eye pressure at a normal level. Secondly, how can I lower my eye pressure naturally? These tips may help you control high eye pressure or promote eye health. Eat a healthy diet. Eating a healthy diet can help you maintain your health, but it won’t prevent glaucoma from worsening. Exercise safely. Limit your caffeine. Sip fluids frequently. Sleep with your head elevated. Take prescribed medicine. What part of the eye does glaucoma affect?Glaucoma is a condition that damages your eye’s optic nerve. It gets worse over time. It’s often linked to a buildup of pressure inside your eye. The increased pressure in your eye, called intraocular pressure, can damage your optic nerve, which sends images to your brain.
