Aim: To describe optical coherence tomography (OCT) images of superior segmental optic hypoplasia (SSOH). Methods: Five patients (two men and three women, ages 10–45 years) presented with ophthalmoscopic features and visual field defects of SSOH. All affected eyes had good visual acuity and inferior altitudinal or inferonasal visual field loss. The mothers of three patients had type 1 diabetes ...
PURPOSE Recently demonstrated neuronal loss in the inner nuclear layer of the retina in multiple sclerosis (MS) and glaucoma raises the question of a primary (possibly immune-mediated) or secondary (transsynaptic) mechanism of retinal damage in these diseases. In the present study we used optical coherence tomography to investigate retrograde retinal transsynaptic degeneration in patients with ...
Primary open-angle glaucoma is a progressive optic neuropathy involving loss of retinal ganglion cells and their axons at the level of the optic nerve head. This change manifests as thinning and excavation of the neural tissues and nerve fiber layer. Therefore, it has long been known that the structural appearance of the optic nerve head is paramount to both glaucoma diagnosis and to the detect...

BACKGROUND AND OBJECTIVE To report on the efficacy of macular and optic nerve spectral-domain optical coherence tomography (SD-OCT) in differentiating between long-standing central retinal artery occlusion (CRAO) and nonarteritic anterior ischemic optic neuropathy (NAION). PATIENTS AND METHODS SD-OCT scans of the macula and optic nerve in 24 patients with unilateral optic atrophy secondary to...
