The visual prognosis in optic nerve hypoplasia is quite variable. Occasionally, optic nerve hypoplasia may be compatible with near-normal vision; in other cases, one or both eyes may be functionally, or legally blind. Although most patients with only optic nerve involvement lead normally productive lives, those with accompanying endocrine ...
The optic nerve is underdeveloped in this condition. Septo-optic dysplasia (SOD), known also as de Morsier syndrome, is a rare congenital malformation syndrome that features a combination of the underdevelopment of the optic nerve, pituitary gland dysfunction, and absence of the septum pellucidum (a midline part of the brain).
Optic nerve hypoplasia is the underdevelopment of the optic nerve resulting in little to no vision in the affected eye. Tumors, especially those of the pituitary gland, can put pressure on the optic nerve causing various forms of visual loss. Similarly, cerebral aneurysms, a swelling of blood vessel(s), can also affect the nerve. Trauma can ...
The foveal area of the eye is located in the back of the eyeball. It is placed in front of the optic nerve and is responsible for light sensory and visual perceptiveness. [3] [4] Other diseases with foveal hypoplasia besides albinism include aniridia, retinopathy of prematurity, and Alport syndrome. [5] [6]
Other names. so called renal-coloboma syndrome or isolated renal hypoplasia, [1] Papillorenal syndrome has an autosomal dominant pattern of inheritance. Specialty. Medical genetics. Papillorenal syndrome is an autosomal dominant [2] genetic disorder marked by underdevelopment (hypoplasia) of the kidney and colobomas of the optic nerve. [3]
The following list includes common symptoms of colpocephaly. [3] [4] [5] partial or complete agenesis of the corpus callosum; intellectual disability; motor abnormalities; visual defects such as, crossing of the eyes, missing visual fields, and optic nerve hypoplasia; spasticity; seizures; cerebral palsy; Intracranial abnormalities include ...
The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy. The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye.
The visual pathway consists of structures that carry visual information from the retina to the brain. Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way: Retina → Optic nerve → Optic chiasma (here the ...
