2014年9月15日 · Optic pits are best seen clinically on dilated fundus evaluation and OCT imaging. They appear as grey, yellow or black excavations in the optic disc and are unilateral 95% of the time (figure 5). 5 In 85% of cases, the optic nerve with the pit is larger than the fellow optic nerve. 5

Optic Pits (also known as optic nerve pits, optic disc pits, or less commonly optic holes) are congenital defects presumably arising from the failure of fetal fissure closure in embryogenesis. Decreased vision occurs in cases if optic pit related maculopathy ensues with either macular edema or serous detachment of the macula.

2021年6月1日 · Optic nerve hypoplasia (ONH) is an important cause of congenital visual impairment in children and infants. It is a unilateral or bilateral malformation of the optic nerve with a wide spectrum of severity.

2006年10月1日 · Optic pits are congenital excavations of the optic nerve head that may be associated with other abnormalities of the optic nerve and peripapillary retina. Optic pits occur in about one in 10,000 people, with no gender predilection, and are usually sporadic.

We report a case of unilateral ODP maculopathy (ODP-M), which is a congenital anomaly of the optic nerve head (ONH) located at the inferotemporal part of the optic disc with multilayered separation involving all retinal layers and connecting with …

2023年2月2日 · Optic nerve hypoplasia (ONH) is a congenital, non-progressive developmental defect that can be characterized by a tiny optic disc, peripapillary "double-ring sign," vascular tortuosity, and nerve fiber layer thinning. 1 ONH occurs bilaterally in 65% of cases and is the third largest cause of childhood blindness in the United States, behind ...

Optic nerve hypoplasia (ONH) is when the optic nerve doesn't grow fully before a baby is born. This makes the nerve smaller than normal. Small optic nerves can be seen with certain brain growth problems.

Optic nerve hypoplasia (ONH) has developed into a leading cause of congenital blindness. The frequently associated features of hypopituitarism and absent septum pellucidum were felt to have embryonic linkage as “septo-optic dysplasia” or “de Morsier’s syndrome.” More recent studies have suggested these associations are independent of one another.

ONH is thought to be one of the most common causes of impaired vision in children under the age of 3 years. It is estimated that 15% to 25% of infants with significant visual impairment have ONH.1,2 Reported incidence ranges between 2.4/100,000 residents (<19 years of age) annually in Olmsted County, Minne­ sota, to 17.3/100,000 residents (<18

Optical coherence tomography (OCT) is widely used to measure the optic nerve head (ONH) neuroretinal rim and the peripapillary retinal nerve fiber layer (RNFL), both being the most popular parameters to distinguish glaucoma by clinicians [5].
