چکیده

Six cases are presented which provide clinical evidence that optic nerve hypoplasia can occur as a result of a lesion at any site in the developing visual system. The mechanisms of hypoplasia are discussed in the light of recent understanding of optic nerve development.

A case of superior segmental optic hypoplasia accompanied by a glaucomatous optic neuropathy

This is the first case report of a bilateral superior segmental optic hypoplasia (SSOH) accompanied by a glaucomatous optic neuropathy (GON). A 47-year-old man incidentally diagnosed as having bilateral SSOH, simultaneously disclosed glaucomatous optic disc appearances, including enlargements of the cup of the optic nerve heads and a thinning of the infero-temporal neuroretinal rim with laminar...

Hypoplasia of the optic nerve.

Hypoplasia of the optic nerve is uncommon (Scheie and Adler, I94I; Somerville, I962; Whinery and Blodi, I963; Ewald, I967). It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...

Uniplanar Nystagmus Associated with Perceptual and Cognitive Visual Dysfunction due to Presumed Focal Ischemic Occipital Cortical Atrophy: A Missed Diagnosis and New Observation

Uniplanar nystagmus has been described in relation to pathology of the brain stem, retina, optic nerve, sensory visual deprivation, periventricular leucomalacia, and drug toxicity. This paper describes a case of uniplanar nystagmus associated with features of higher visual dysfunction and a presumed focal insult to the occipital lobes following an episode of neonatal apnea.

Central neural influences on the human retina during selective attention

Two controversial issues were investigated. One concerned the question of whether cen· trifugal fibers project to the human retina, and the other, the question of whether precortical fil· ters which differentially transmit relevant and irrelevant information during selective attention exist. The issues were addressed jointly by studying the effects of selective attention on evoked responses obt...

The end in sight: a look at the occipital lobe

The occipital lobe is the endpoint of the visual pathway and the part which is most fully concerned with vision. This paper will first describe the anatomy of the occipital lobe including functions of cell types, topographical retinal representation, and vascular supply. A detailed discussion of the clinical manifestations of occipital lobe lesions including patient symptoms, visual field defec...
