(2) The cranial neural crest is the origin of the ciliary body, including pigmented and nonpigmented cells and the ciliary smooth muscle, and it starts to form in the third month as a fold posterior to the progressing edge of the optic cup
. (3,4) Developmental defects in embryogenesis cause ocular malformations in a spectrum from congenital cataract to anophthalmia.
Changes in the myopic fundus, such as disc rotation, distortion, and deformation,, affect the observations of shape and size of the optic cup
and disc and interfere with the qualitative analysis of glaucoma in myopia and the accuracy of quantitative examinations.
The detection and diagnosis of glaucoma are related to tracing the changes in the optic cup
which is a portion of optic disc (OD).
07 When viewed monoscopically, the border between the neuroretinal rim and optic cup
is best defined by:
The morphology of disc in POAG is characterized by thinning of the neuroretinal rim, excavation of the optic cup
, and a higher cup/disc ratio (9,10).
OD(Optic Disc) and OC(Optic Cup
)  were segmented using superpixel classification for glaucoma screening.
He walks readers through optic disk size and shape; optic cup
shape and depth; optic cup
size in relation to the optic disc size; neuroretinal rim size, shape and perfusion; central retinal vessel trunk location; optic disc hemorrhages; parapapillary chorioretinal atrophy; retinal arteriole diameter; and retinal nerve fiber layer defects.
In addition to Lancaster's team, several other teams developed region-specific neural organoid such as the neocortex , telencephalon , cerebellar , neural tube , pituitary gland , hippocampus cortex , optic cup
, neural retina , and inner ear sensory epithelial tissue.
(3,4) Occasionally referred to as "common" or "idiopathic," nonarteritic anterior ION tends to affect optic discs with a small-diameter scleral canal and optic cup
, the so-called disc at risk.
