[95] Flow Of Aqueous Humor In Eye Herunterladen. Doctors use a number of different categories of eye drops to treat glaucoma. It provides nutrition to the eye as well as maintains the eye in a pressurized state. These substances are called the vitreous humor and aqueous.
From there the aqueous humour exits the eye through the trabecular meshwork into schlemm s canal a channel at the limbus i e the joining point of the cornea and sclera which encircles the cornea it flows through 25 30 collector canals into the episcleral veins. Langley d macdonald rk. Identification of a fluorescein tracer model for determination of the flow rate of aqueous humor in the eye.
The most common treatments for glaucoma are eye drops and rarely pills. Aqueous humor flows from the ciliary body into the anterior chamber out through a spongy tissue at the front of the eye called the trabecular meshwork and into a drainage canal dark blue region next to the trabecular meshwork. Clinical method of observing changes in the rate of flow of aqueous humour in the human eye.
Posterior synechia also cause glaucoma but with a different mechanism. Aqueous humor is produced by the epithelium of the ciliary body. It is secreted into the posterior chamber from which it flows through the pupil to enter the anterior chamber.
The aqueous humor is drained into the canal of schlemm which is a venous sinus found near the limbus. Condition in which aqueous humor fails to drain properly and accumulates in the anterior chamber of the eye causing elevated interocular press iop. They either decrease the amount of fluid aqueous humor in the eye or improve its outward flow and some do both.
In the healthy eye a clear fluid called aqueous humor circulates inside the front portion of your eye. If you have glaucoma the aqueous humor does not flow out of the eye properly. In posterior synechia the iris adheres to the lens blocking the flow of aqueous humor from the posterior chamber to the anterior chamber.
Vitreous and aqueous humor gel like fluids inside the eye help it maintain its shape which plays an important role in overall eye health. To maintain a constant healthy eye pressure your eye continually produces a small amount of aqueous humor while an equal amount of this fluid flows out of your eye. Flow in abnormal eyes aqueous humor flow has been studied in a number of systemic and ocular conditions including chronic open angle glaucoma low tension glaucoma ocular hypertension exfoliation syndrome pigment dispersion horner s syndrome fuchs dystrophy myotonic dystrophy diabetes mellitus cystic fibrosis and carotid stenosis.
