Unusual Coloboma of the Optic Nerve Entrance.
DEVELOPMENTAL anomalies of the eye in the region of the optic disc are commonly divided into two groups: those in which failure of coaptation occurs within the optic nerve sheath and those showing lesions of the peripapillary choroid or sclera. With the exception of the small holes sometimes seen on the anterior surface of the optic disc, which are probably related to aberrant formation of Berg...
متن کاملColoboma of the optic nerve entrance.
THIS case of a coloboma of the optic nerve entrance is recorded because of the great scarcity of previous histological reports. Only very rarely is a coloboma found to be restricted to the optic nerve entrance (Duke-Elder, 1964); the great majority affect the adjacent choroid as well. Many of the early reports concerned eyes from animals or from anencephalic stillborn infants. These as well as ...
متن کاملColoboma of optic nerve with overlay of peripapillary retina.
An eye that had the clinical appearance of a tumour of the nerve head was found on histological examination to have a congenitally large scleral canal with secondary buckling of the overlying retina.
متن کاملDeficient FGF signaling causes optic nerve dysgenesis and ocular coloboma.
FGF signaling plays a pivotal role in eye development. Previous studies using in vitro chick models and systemic zebrafish mutants have suggested that FGF signaling is required for the patterning and specification of the optic vesicle, but due to a lack of genetic models, its role in mammalian retinal development remains elusive. In this study, we show that specific deletion of Fgfr1 and Fgfr2 ...
