ANATOMY OF THE AN G LE OF THE EYE BY YUSSUF AND KOECH
Function of the angle It’s the site where the trabecular meshwork lies and is therefore the part of the eye that is responsible for aqueous outflow, closed angle glacuoma results when flow is blocked Gonioscopy is an essential diagnostic tool and exam technique used to visualize the structures of the anterior chamber angle.
Structures of the angle Schwalbe,s line Trabecular meshwork and schlemm canal Scleral spar Anterior border of the ciliary body Iris root
Applied anatomy Hyphema – blood fills the anterior chamber due to hemorrhage arising from blunt injury Anterior uveitis – inflammatory process affecting iris and cilliary body resulting in inflammatory signs in the anterior chamber Blockage of the trabecular meshwork prevents normal flow of the aqueous humour resulting in IOP, leading to pressure on optic nerve and eventual blindness Schlemn canal collapse causes aqueous out flaw blockage, this is prevented by the scleral spur
