WebCiliary body is covered by pars ciliaris retinae (ciliary part of retina), whose outer layer contains pigmented epithelium and inner layer contains non-pigmented epithelium. Iris partially covers the lens as projections of choroid. The central aperture creates pupil. WebThe pars ciliaris retinae is recognized by its marked folding Externally, it is covered by a layer of mesenchyme which forms the ciliary muscle Internally, it is connected to the lens by a network of elastic fibers which form the suspensory ligament or zonula
The ora serrata is the serrated junction between the choroid and the ciliary body. This junction marks the transition from the simple, non-photosensitive area of the ciliary body to the complex, multi-layered, photosensitive region of the retina. The pigmented layer is continuous over choroid, ciliary body and iris while the nervous layer terminates just before the ciliary body. This point is th…
