Compartments Flashcards
(34 cards)
What are the three main compartments of the eye?
Anterior chamber, posterior chamber, vitreous chamber
Where is the anterior chamber located?
Between the cornea and the iris
Where is the posterior chamber located?
Between the iris and the lens
Where is the vitreous chamber located?
Between the lens and the retina
What fluid fills the anterior and posterior chambers?
Aqueous humor
What fluid fills the vitreous chamber?
Vitreous humor (gel-like)
What produces aqueous humor?
Ciliary processes of the ciliary body
How does aqueous humor flow?
From posterior chamber → through pupil → into anterior chamber → drains via trabecular meshwork to canal of Schlemm
What is the function of aqueous humor?
Nourishes the avascular lens and cornea; maintains intraocular pressure
What is the function of the vitreous humor?
Maintains eye shape and holds the retina against the choroid
What separates the anterior and posterior chambers?
The iris
What separates the posterior chamber from the vitreous chamber?
The lens
What can increased intraocular pressure indicate?
Glaucoma
Which chamber is most involved in open-angle glaucoma?
Anterior chamber (drainage of aqueous humor is impaired)
What is the canal of Schlemm?
A circular drainage channel at the junction of the cornea and sclera for aqueous humor outflow
What structure anchors the lens in place?
Suspensory ligaments (zonules of Zinn)
What happens if the vitreous humor detaches?
Posterior vitreous detachment — may cause floaters or retinal detachment
What are the three main compartments of the eye?
Anterior chamber, posterior chamber, vitreous chamber
Where is the anterior chamber located?
Between the cornea and the iris
Where is the posterior chamber located?
Between the iris and the lens
Where is the vitreous chamber located?
Between the lens and the retina
