The discipline applies to all animal eyes, whether human or not, since the practice and procedures are quite similar with respect to disease processes, although there are differences in the anatomy or disease prevalence. [109] => [110] => ==History== [111] => ===Ancient near east and the Greek period=== [112] => In the [[Ebers Papyrus]] from ancient Egypt dating to 1550 BC, a section is devoted to eye diseases. [113] => [114] => Prior to [[Hippocrates]], physicians largely based their anatomical conceptions of the eye on speculation, rather than [[empiricism]]. They recognized the sclera and transparent cornea running flushly as the outer coating of the eye, with an inner layer with pupil, and a fluid at the centre. It was believed, by [[Alcamaeon]] (fifth century BC) and others, that this fluid was the medium of vision and flowed from the eye to the brain by a tube. [[Aristotle]] advanced such ideas with empiricism. He dissected the eyes of animals, and discovering three layers (not two), found that the fluid was of a constant consistency with the lens forming (or congealing) after death, and the surrounding layers were seen to be juxtaposed. He and his contemporaries further put forth the existence of three tubes leading from the eye, not one. One tube from each eye met within the skull. [115] => [116] => The Greek physician [[Rufus of Ephesus]] (first century AD) recognised a more modern concept of the eye, with [[conjunctiva]], extending as a fourth epithelial layer over the eye. Rufus was the first to recognise a two-chambered eye, with one chamber from cornea to lens (filled with water), the other from lens to retina (filled with a substance resembling egg whites). [117] => [118] => [[Celsus]] the Greek philosopher of the second century AD gave a detailed description of cataract surgery by the [[Couching (ophthalmology)|couching]] method. [119] => [120] => The Greek physician [[Galen]] (second century AD) remedied some mistaken descriptions, including about the curvature of the cornea and lens, the nature of the optic nerve, and the existence of a [[posterior chamber of eyeball|posterior chamber]]. Although this model was a roughly correct modern model of the eye, it contained errors. Still, it was not advanced upon again until after [[Vesalius]]. A [[ciliary body]] was then discovered and the sclera, retina, choroid, and cornea were seen to meet at the same point. The two chambers were seen to hold the same fluid, as well as the lens being attached to the choroid. Galen continued the notion of a central canal, but he dissected the optic nerve and saw that it was solid. He mistakenly counted seven optical muscles, one too many. He also knew of the [[tear duct]]s.
