damage to photoreceptors will cause to decline?
diabetic retinopathy
diabetic individual are at risk of developing what in the eyeball?

the capillaries of the ciliary processes secretes aqueous humor into the anterior or posterior chamber?
blood
the capillaries of the ciliary processes secretes aqueous humor into the posterior chamber, then the aqueous humor circulates thru the pupil to the anterior chamber of the anterior cavity, and is reabsorbed by what?
pupil
the capillaries of the ciliary processes secretes aqueous humor into the posterior chamber, then the aqueous humor circulates thru what to get the anterior chamber of the anterior cavity?
anterior cavity
the fibrous and vascular tunic have a relationship with which cavity?

the poster chamber is between what?
vitreous chamber
the posterior cavity can also be called what?
vitreous body
the posterior cavity contains what?
retina
the posterior cavity has contact with which tunic layer of the eyeball?
lens and retina
the posterior cavity is between what two parts of the eyeball?
aqueous humor
the pupil circulates what from the poster chamber to the anterior chamber?
anterior cavity
the scleral venous sinus/canal of schlemm is found in which cavity of the eyeball?
anterior chamber
the scleral venous sinus/canal of schlemm is found in which chamber of the anterior cavity?
chambers
the subdivision of the anterior cavity is classified as what?
choroid
the vitreous body holds the retina against what?
the eyeball from collapsing
the vitreous body prevents what?
helps maintain the intranocular pressure of the eyeball and supplies nutrients to the lens and cornea
what are the two primary functions of the aqueous humor?
diabetic retinopathy
what can causes increase number of blood vessels and rupturing of blood vessels over the retina?
when fluid accumulates in the anterior cavity
what causes intraocular pressure of the eyeball to rise?
posterior cavity
what contains the vitreous body?
