Eye model 5 x normal size in 7 parts

Anatomically, this model focuses on the anatomy of the eyeball, and only a small part of the orbit is shown below the eyeball.



The model shows the structure of the eyeball with its different layers:



The outermost layer is made up of the transparent cornea, which at the limbus is connected to the sclera (the white tendon that makes up the back 5/6).


The middle layer (called the uvea) which consists of the iris (rainbow) incl. the pupil, the corpus ciliare (the ray body) of which the ciliary muscle is primarily seen and the choroid (the choroid).


The innermost layer is called the retina.


The outermost layer of the eyeball can be halved and removed, so that the vitreous body (corpus vitreum) and the lens become visible. These are also removable. On the back of the model, you can see how the optic nerve (N. opticus) leaves the eyeball together with the vein and artery that supply the nerve.



On the outside of the white tendon membrane (sclera) you can see the attachment of the 6 striated muscles that control eyeball movements. These are divided into the 4 straight muscles (musculi recti) and the 2 oblique muscles (musculi obliqui).

Clinically, the model can be used to understand diseases of the eye. It can be, for example, "red eye", retinal detachment, vitreous collapse, diabetic eye disease, uveitis, scleritis as well as metastases and primary tumors such as malignant melanomas (birthmark cancer) in the uvea.
