164. Bilateral Visual Loss: More Than Meets The Eye. (PubMed)

Bilateral Visual Loss: More Than Meets The Eye. A 72-year-old woman presented with acute onset bilateral visual loss. She had no other symptoms or signs, but had a complex past medical history including blood transfusions and immunosuppression. T2-weighted magnetic resonance imaging demonstrated bilateral occipital lobe vasogenic edema, consistent with posterior reversible encephalopathy syndrome (PRES). Her vision improved with conservative management.Copyright © 2013 Elsevier Inc. All rights

165. Ganglion Cell Loss in Relation to Visual Disability in Multiple Sclerosis. (PubMed)

Ganglion Cell Loss in Relation to Visual Disability in Multiple Sclerosis. We used high-resolution spectral-domain optical coherence tomography (SD-OCT) with retinal segmentation to determine how ganglion cell loss relates to history of acute optic neuritis (ON), retinal nerve fiber layer (RNFL) thinning, visual function, and vision-related quality of life (QOL) in multiple sclerosis (MS).Cross-sectional study.A convenience sample of patients with MS (n = 122; 239 eyes) and disease-free (...) was significant even accounting for macular RNFL thickness (P = 0.03 for GCL+IPL, P = 0.39 for macular RNFL).We demonstrated that GCL+IPL thinning is most significantly correlated with both visual function and vision-specific QOL in MS, and may serve as a useful structural marker of disease. Our findings parallel those of magnetic resonance imaging studies that show gray matter disease is a marker of neurologic disability in MS.Proprietary or commercial disclosure may be found after the references.Copyright ©

months later were investigated for their association with later axonal loss.After multivariate analysis, prolonged visual evoked potential latency and impaired color vision, at baseline and after 3 months, were significantly and independently associated with RNFL thinning. Low-contrast acuity measures exhibited significant univariate associations with RNFL thinning.The association of RNFL loss with a prolonged visual evoked potential (VEP) latency suggests that acute and persistent demyelination (...) Early factors associated with axonal loss after optic neuritis. Acute optic neuritis due to an inflammatory demyelinating lesion of the optic nerve is often seen in association with multiple sclerosis. Although functional recovery usually follows the acute episode of visual loss, persistent visual deficits are common and are probably due to axonal loss. The mechanisms of axonal loss and early features that predict it are not well defined. We investigated clinical, electrophysiological

171. Acute visual changes in the elderly. (PubMed)

Acute visual changes in the elderly. Changes in vision are common complaints among the geriatric population. Causes range from cataracts and glaucoma to cerebral strokes or other systemic diseases. Loss of vision may be the turning point from independence to dependence in an elderly person's life. This article focuses on acute vision changes and provides a systematic, symptom-based approach to the evaluation and diagnosis of these processes. It is important that the primary practitioner (...) or geriatrician recognize and evaluate acute vision changes, determine whether a treatable or reversible condition exists, and know when to refer to an ophthalmologist or neurologist for a complete evaluation and management.Copyright © 2013 Elsevier Inc.

known as orthostatic hypotension (OH). Due to a decrease in cerebral oxygenation, affected individuals can develop debilitating symptoms including lightheadedness, blurred vision, fatigue and even loss of consciousness. Recent evidence suggests that OH has a negative impact on cognition in individuals with SCI. Clinical observations suggest that OH can lead to neurological deterioration in individuals who may otherwise have a stable SCI. The presence of symptomatic OH prevented participation in 43 (...)

Acute visual loss after spinal surgery. To report visual loss after prone spinal surgery.Computed tomography scan, fundus photography, optical coherence tomography (OCT).A 56-year-old man demonstrated loss of vision in the left eye after cervical spinal surgery. Clinical examination revealed loss of vision to finger counting, severe visual field defect and blurred neural rim area around the optic disc in the left eye. Six weeks later, visual acuity in the left eye was 6/9 and there was inferior (...) visual field defect. Six months after the surgery, significant reduction of retinal nerve fibre layer thickness around the optic nerve head was measured with OCT, consistent with the visual field defect.Ischemic optic neuropathy is the most common cause of visual loss after spine surgery and special emphasis should be given to protect the eye against possible pressure during the surgery.

Cystoid Macular Edema in Acute Presentation of Central Retinal Artery Occlusion A seventy-six-year-old lady with poor vision of the left eye due to previous retinal detachment presented with acute visual loss of her right eye secondary to central retinal artery occlusion. Clinical examination showed a pale right optic disc, macular edema, and a cherry red spot. Optical coherence tomography done four hours after onset showed right acute cystoid macular edema and diffuse inner retinal thickening (...) . Subsequent treatment with intravenous carbonic anhydrase inhibitor resulted in some visual improvement. Central retinal artery occlusion has been known to produce diffuse intraretinal edema instead of cystoids changes. We would like to discuss a case of acute cystoid macular edema in acute central retinal artery occlusion.
