Proboscis in Patau syndrome. Cyclopia (a single median eye) is associated with arrhinia (absence of the nose) and proboscis formation above the eye.. In teratology, a proboscis is a blind-ended, tube-like structure, commonly located in the middle of the face.
Leonardo da Vinci: The eye has a central line and everything that reaches the eye through this central line can be seen distinctly. Alhazen (965 – c. 1040) carried out many investigations and experiments on visual perception, extended the work of Ptolemy on binocular vision , and commented on the anatomical works of Galen.
Photophobia and decreased visual acuity due to light scattering within the eye (ocular straylight) [8] [12] Reduced visual acuity due to foveal hypoplasia and possibly light-induced retinal damage. [8] Eye conditions common in albinism include: Nystagmus, irregular rapid movement of the eyes back and forth, or in circular motion. [8]
Aphakia is the absence of the lens of the eye, due to surgical removal, such as in cataract surgery, a perforating wound or ulcer, or congenital anomaly. It causes a loss of ability to maintain focus ( accommodation ), high degree of farsightedness ( hyperopia ), [ 1 ] and a deep anterior chamber .

The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter . [ 1 ] Correction of spherocylindrical refractive errors has been possible for nearly two centuries following Airy's development of methods to measure and ...
Several layers such as the neural tube, neural crest, surface ectoderm, and mesoderm contribute to the development of the eye. [2] [3] [4] Eye development is initiated by the master control gene PAX6, a homeobox gene with known homologues in humans (aniridia), mice (small eye), and Drosophila (eyeless). The PAX6 gene locus is a transcription ...
