Cecocentral scotoma as the initial manifestation of subacute bacterial endocarditis
INTRODUCTION We report a case of a 67-year-old male who presented with a cecocentral scotoma caused by a septic embolus from subacute bacterial endocarditis (SBE). METHODS A 67-year-old man presented with sudden, painless decreased vision in the left eye. A dilated fundoscopic exam, Humphrey visual field test, transthoracic echocardiogram, abdominal computed tomography (CT), and blood culture...
متن کاملBitemporal hemianopia; its unique binocular complexities and a novel remedy.
Bitemporal hemianopic visual field impairment frequently leads to binocular vision difficulties. Patients with bitemporal hemianopia with pre-existing exophoria complain of horizontal diplopia, sometimes combined with vertical deviation (with pre-existing hyperphoria). The symptoms are a result of the phoria decompensating into a tropia (hemi-slide) due to the lack of retinal correspondence bet...
متن کاملIsolated complete bitemporal hemianopia in traumatic chiasmal syndrome
A 29-year-old man presented with a chief complaint of lateral blindness in the left eye at 4 months after an accidental fall. His best corrected visual acuity was 0.7 in the left eye and 1.0 in the right eye. Visual field test showed a complete bitemporal hemianopic defect without any neurologic symptoms. An orbital computed tomography scan with non-enhancement conducted at the time of the visi...
متن کاملMultiplexing Prisms for Field Expansion.
PURPOSE Prisms used for field expansion are limited by the optical scotoma at a prism apex (apical scotoma). For a patient with two functioning eyes, fitting prisms unilaterally allows the other eye to compensate for the apical scotoma. A monocular patient's field loss cannot be expanded with a conventional or Fresnel prism because of the apical scotoma. A newly invented optical device, the mul...
متن کاملVisual field defects of optic neuritis in neuromyelitis optica compared with multiple sclerosis
BACKGROUND Neuromyelitis optica (NMO) is an inflammatory demyelinating disease that predominantly affects the optic nerves and the spinal cord, and is possibly mediated by an immune mechanism distinct from that of multiple sclerosis (MS). Central scotoma is recognized as a characteristic visual field defect pattern of optic neuritis (ON), however, the differing pathogenic mechanisms of NMO and ...
