The posterior segment is the back two-thirds of the
eyethat includes the anterior hyaloid membraneand all of the optical structures behind it: the vitreous humor, retina, choroid, and optic nerve. [ [http://www.e-sunbear.com/anatomy_04.html Posterior segment anatomy] ]
ophthalmologists specialise in the treatment and management of posterior segment disorders and diseases. [ [http://www.neec.com/pages/Vitreoretinal_Disease.html Vitreoretinal Disease & Surgery - New England Eye Center] ]
The posterior segment is the back two-thirds of the eye that includes the
anterior hyaloid membraneand all structures behind it: the vitreous humor, retina, choroid, and optic nerve. [ [http://www.e-sunbear.com/anatomy_04.html Posterior segment anatomy] ] On the other side of the lens is the second humour, the aqueous humour, which is bounded on all sides: by the lens, ciliary body, suspensory ligaments and by the retina. It lets light through without refraction, helps maintain the shape of the eye and suspends the delicate lens. In some animals, the retina contains a reflective layer (the tapetum lucidum) which increases the amount of light each photosensitive cell perceives, allowing the animal to see better under low light conditions.
