	Hi team :D I just found an article that talks about all the current knowledge on conditions related to abnormal visual development in infants. In the article, they have aslo included prevalence, risk factors and mechanisms that are involved with the development of these conditions. I think it would be quite useful to our own topic. Just letting everyone know, i will be doing congenital cataracts. [http://www.ncbi.nlm.nih.gov/pubmed/21478704]--[[User:Z3331330\|Z3331330]] 12:36, 29 August 2012 (EST)

			File:Aristotle-eye.jpg\|The eye according to Aristotle. Credits: Magnus, 1901. Note the lens is missing, and there are three vessels drawn that was believed to transport fluid to and from the eye.

			File:Celsus-eye.jpg\|The eye according to Celsus. Credits: Magnus, 1901. Note the lens is placed in the centre of the eye, in the vitreous.

			File:Rufus-eye.jpg\|The eye according to Rufus of Ephesus. Credits: Magnus, 1901. Note the lens is placed in the correct position, behind the iris of the eye

			File:Galen-eye1.jpg\|The eye according to Galen. Credits: Magnus, 1901.

			File:Kollmann691.jpg\|The blue part at the bottom is the endoderm. The pink middle layer is the mesoderm. The top yellow layer is the ectoderm. The fold labelled as 'augenfeld' is the place where the optic vesicle will form. Credits: Kollmann, J. (1907)

			File:Kollmann692.jpg\|The eye area (augenfeld) is a bowl shaped bulge still located on the side walls. Credits: Kollmann, J. (1907)


			File:Kollmann693.jpg\| The neural tube is shown after removal of all of the ectoderm and ventral organs, such as heart, gut tube, etc. The primary optic vesicle forms a slightly flattened hollow protrusion on the forebrain. Credits: Kollmann, J. (1907)


			File:Kollmann694.jpg\|The lateral surface of the primary optic vesicle is slightly depressed, showing the first sign of the emergence of the secondary optic vesicle. Credits: Kollmann, J. (1907)

			File:Kollmann695.jpg\|The bulging lateral wall of the primary optic vesicle is covered by a fairly well demarcated lens plate, a direct continuation of the ectoderm. Between the optic vesicle and the lens pit are some flattened spindle-shaped cells. In the adjoining mesoderm are cross-sections of capillaries. Credits: Kollmann, J. (1907)
			File:Kollmann697.jpg\|The lens still hangs together with the ectoderm. The primary eye vesicle is indented with respect to the lens. Between the lens and the lateral plate of the optic vesicle is a narrow space, which allows area to further develop later. Credits: Kollmann, J. (1907)

			File:Kollmann698.jpg\|4th Week of development. The internal organisation shows the secondary optic vesicle. A: The rear wall of lens is noticeable and is enveloped by mesoderm. B: The edges of the lens pit is already grown and the lens vesicles are formed, which is still related to the remaining ectoderm. Credits: Kollmann, J. (1907)

			File:Kollmann699.jpg\|The lens has now cut off from the ectoderm, but is still very superficial. Between it and the lateral lamina of the optic cup, there is a considerable space. The eye stalk has become longer and is enclosed together with the optic cup and lens of the mesoderm. The cornea, sclera and choroid make gradual development. Credits: Kollmann, J. (1907)
