Uveal tract The uveal tract is composed of the iris the ciliary body, and the choroid It contributes blood supply to the retina vitreous
Uveal Tract • The uveal tract is composed of the iris, the ciliary body, and the choroid • It contributes blood supply to the retina
Iris The iris is the anterior extension of the ciliary bod. It presents as a flat surface with a centrally situated round aperture, the pupil controls the amount of light entering the eye
Iris • The iris is the anterior extension of the ciliary body • It presents as a flat surface with a centrally situated round aperture, the pupil • controls the amount of light entering the eye
The ciliary body roughly triangular in cross-section extends forward from the anterior end of the choroid to the root of the iris The ciliary processes and their covering ciliary epithelium are responsible for the formation of aqueous The ciliary muscle alters the tension on the capsule of the lens accomodation)
The Ciliary Body • roughly triangular in cross-section • extends forward from the anterior end of the choroid to the root of the iris • The ciliary processes and their covering ciliary epithelium are responsible for the formation of aqueous • The ciliary muscle alters the tension on the capsule of the lens (Accomodation)
