Vitreous Degeneration


Presentation

  • The observation that a more formed vitreous is present in eyes affected by VMT or MH as observed during pars plana vitrectomy repair by the senior author and the OCT correlation presented in this study support the notion that vitreous degeneration or[ncbi.nlm.nih.gov]
  • Clinically, paresthesia, sensory ataxia, and sometimes spastic paraplegia are present. The disease is the result of pernicious anemia. vacuolar degeneration Swelling of cells with an increase in the number and size of vacuoles.[medical-dictionary.thefreedictionary.com]
  • All retinal detachments require emergent ophthalmologic consult. 1 Differentiating between the three conditions often presents a diagnostic quandary because all three may have similar presenting symptoms.[emra.org]
Physician
  • Subjects A retrospective chart review was performed on patients who presented with VMT or MH as a manifestation of an anomalous PVD to a single physician (ME) between February 2013 and November 2015 (VMT/MH group).[ncbi.nlm.nih.gov]
Swelling
Asymptomatic
Inflammation
  • […] finding in the brain cells of some patients with Alzheimer's dementia in which the neuronal cytoplasm is partly replaced by cavities that contain particles resembling grit or sand. gray degeneration Degeneration in myelinated nerve tissue due to chronic inflammation[medical-dictionary.thefreedictionary.com]
Retinal Pigmentation
  • In dry MD, the more common and more benign form, hard and soft drusen accumulate beneath the retinal pigment epithelium. They may cause slowly progressive blurring of central vision or may occasionally and gradually lead to wet MD.[medical-dictionary.thefreedictionary.com]
Central Scotoma
Photopsia
  • […] more common among women. [2] [3] Symptoms [ edit ] Weiss ring: a large, ring shaped floater that is sometimes seen if the vitreous body releases from the back of the eye When this occurs there is a characteristic pattern of symptoms: Flashes of light ( photopsia[en.wikipedia.org]
Suggestibility
  • —We read with interest the recent contribution of Ogura et al, 1 which suggested that vitreous fluorophotometry may assist in studying vitreous degeneration in conditions such as retinitis pigmentosa (RP).[jamanetwork.com]
  • Prevascular vitreous fissures were connected with cisterns in 44 of the 71 (62%) eyes with cisterns, while the base of the cistern was directly above retinal blood vessels in 38 (54%) eyes, which suggests that the cisterns could be derived from PVF.[insights.ovid.com]
  • However, this study suggests that progression of vitreous degeneration is not a causative factor in vitreoretinal interface disease but may in fact be preventative.[ncbi.nlm.nih.gov]
  • […] floaters will usually become less and less noticeable, and eventually most symptoms will completely disappear. [7] Prompt examination of patients experiencing vitreous humor floaters combined with expeditious treatment of any retinal tears has been suggested[en.wikipedia.org]
  • […] performed by a single operator reported 92.3% sensitivity and 98.3% specificity for identifying retinal detachment, 96.2% and 100% for posterior vitreous detachment, and 100% and 100% for vitreous hemorrhage. 8 The study has limitations, but results suggest[emra.org]
Neglect
  • However, our understanding of the role of the vitreous body itself in this spectrum of disease has been neglected.[ncbi.nlm.nih.gov]
Encephalopathy
  • […] grit or sand. gray degeneration Degeneration in myelinated nerve tissue due to chronic inflammation, causing the nerve tissue to turn gray. hepatocerebral degeneration Loss of nerve and supporting cells of the brain from multiple episodes of hepatic encephalopathy[medical-dictionary.thefreedictionary.com]
Ataxia
  • Clinically, paresthesia, sensory ataxia, and sometimes spastic paraplegia are present. The disease is the result of pernicious anemia. vacuolar degeneration Swelling of cells with an increase in the number and size of vacuoles.[medical-dictionary.thefreedictionary.com]
Paresthesia
  • Clinically, paresthesia, sensory ataxia, and sometimes spastic paraplegia are present. The disease is the result of pernicious anemia. vacuolar degeneration Swelling of cells with an increase in the number and size of vacuoles.[medical-dictionary.thefreedictionary.com]
Spastic Paraplegia
  • Clinically, paresthesia, sensory ataxia, and sometimes spastic paraplegia are present. The disease is the result of pernicious anemia. vacuolar degeneration Swelling of cells with an increase in the number and size of vacuoles.[medical-dictionary.thefreedictionary.com]

Treatment

  • However, this form of treatment is complicated by a high rate of recurrence and some immediate visual loss in a scotoma.[medical-dictionary.thefreedictionary.com]
  • Schedule Eye Exam VISION THERAPY Vision Therapy treatment addresses developmental or acquired visual deficits that impact patients’ daily lives in their academic, sports, and workplace performance.[eyecarespecialties.com]
  • The implications of this theory may alter the way we think about not only the pathogenesis but also future treatment paradigms of VMT-MH spectrum disorders.[ncbi.nlm.nih.gov]
  • In these cases, additional imaging such as Optical Coherence Tomography (OCT) or ocular ultrasound are used. [6] Treatment [ edit ] Therapy is not required or indicated in posterior vitreous detachment, unless there are associated retinal tears, which[en.wikipedia.org]
