Visual Impairment

Diminished Vision


Presentation

  • In the present case, the only presenting symptom was visual impairment. These changing trends in presentation, the extent, and the area of involvement are challenging for the otorhinolaryngologist, ophthalmologist, and neurosurgeon.[ncbi.nlm.nih.gov]
  • If the presenting near vision was worse than 6/12 (log MAR 0.3), then it was re-assessed with addition lens appropriate to the age. NVI was defined as binocular presenting near vision worse than 6/12.[ncbi.nlm.nih.gov]
  • Macula and the lesions that could be visualized were evaluated by spectral domain optical coherence tomography (SOCT) at presentation.[ncbi.nlm.nih.gov]
  • Acute subperiosteal hematoma of orbit is a rare condition and its presentation with rapid severe diminution of vision is even rarest. Urgent intervention is required for these patients presenting with visual compromise.[ncbi.nlm.nih.gov]
  • An abnormal b-wave amplitude and an increased peak III latency at VEPs were present on admission and recovered within 24 hours. Fomepizole appeared safe and effective for a patient who had severe methanol poisoning presenting with visual impairment.[ncbi.nlm.nih.gov]
Abdominal Obesity
  • Abdominal obesity was estimated using waist-to-height ratio; a cutoff point of 0.50 was determined as central obesity.[ncbi.nlm.nih.gov]
  • OBJECTIVE: The aims of the study were to assess the level of physical activity (PA) in students with VI, with regard to their age, gender, level of VI, body mass index and abdominal obesity (AO), and to identify the percentage of study participants who[ncbi.nlm.nih.gov]
Malingering
  • RESULTS: Cases of blindness in 55 characters (2 as a choir) from 38 operas were detected over 3 centuries of repertoire: 11 had trauma-related visual impairment, 5 had congenital blindness, 18 had visual impairment of unknown cause, 9 had psychogenic or malingering[ncbi.nlm.nih.gov]
Purpura
  • Purpura was detected in the area from the glabella to the left forehead. An orbital computed tomography (CT) scan demonstrated high-density deposits along vessels in the left medial orbit and forehead.[ncbi.nlm.nih.gov]
Macrocephaly
  • Additional features, including central visual impairment, relative macrocephaly, retrognathia, preauricular tags, and bilateral club-feet, were noticed.[ncbi.nlm.nih.gov]
Corneal Edema
  • Although her consciousness stabilized after a few days, the vision in her left eye deteriorated due to corneal edema and both hypopyon and hyphema in the anterior chamber, and the skin from the glabella to the left forehead developed necrosis.[ncbi.nlm.nih.gov]
Withdrawn
  • Each child was awake but appeared withdrawn without verbal output. No child blinked to threat or fixed or followed. In each case, pupillary reactivity was normal, and funduscopic examinations revealed only papilledema. One child reached for money.[ncbi.nlm.nih.gov]
Generalized Seizure
  • This disconnection of overlying cortex may allow an "epileptogenic" island of cortex to generate seizures.[ncbi.nlm.nih.gov]

Workup

  • After additional workup including lumbar puncture with an opening pressure of 55 cm H2O, a diagnosis of IIH was confirmed.[ncbi.nlm.nih.gov]

Treatment

  • The mutant constructs could not rescue the PGAP1-deficient CHO cell lines resistance to PI-PLC treatment.[ncbi.nlm.nih.gov]
  • Some causes of visual impairment are consequences or complications of MS treatment and are particularly important to recognize.[ncbi.nlm.nih.gov]
  • Treatment was stopped and the retinopathy was followed up for 4 months by ophthalmic examination and high-resolution optical coherence tomography.[ncbi.nlm.nih.gov]
  • There are equally a wide variety of treatment options available for these individuals.[ncbi.nlm.nih.gov]
  • In treatment of SESS, the intradural approaches result to be more effective, guaranteeing the best visual outcomes with the lowest complications rates.[ncbi.nlm.nih.gov]

Prognosis

  • VEPs were also severely abnormal in the infants with the worst visual outcome, but were not providing a more reliable prognosis.[ncbi.nlm.nih.gov]
  • The prognosis for recovery is excellent and parallels the return of normal speech. The mechanism is unclear.[ncbi.nlm.nih.gov]
  • Prognosis The prognosis generally relates to the severity of the impairment and the ability of the aids to correct it. A good low vision exam is important to be aware of the latest low vision aids.[medical-dictionary.thefreedictionary.com]
  • It is important to understand each student's visual impairment in order to understand the potential impact on the student's vision and prognosis. A visual diagnosis will not affect two people in the same way.[teachingvisuallyimpaired.com]
  • It is important to note that not all researchers agree on the full range of causes, the prognosis or even the proper diagnostic label used to describe vision loss due to brain damage.[tech.aph.org]

Etiology

  • The potential etiologies of postoperative visual loss are reviewed, and recommendations for avoiding this complication are discussed.[ncbi.nlm.nih.gov]
  • It ranks only behind arthritis and heart disease as the etiology for impaired function in those over the age of 70. Macular degeneration is a leading cause of blindness and poor vision in the elderly.[ncbi.nlm.nih.gov]
  • The aim of this study was determine the prevalence, etiology and the factors associated with childhood visual impairment among the children attending the eye clinic in Mulago National Referral Hospital.[ncbi.nlm.nih.gov]
  • RESULTS: The etiology of visual impairment is different in primary and secondary ESS.[ncbi.nlm.nih.gov]

Epidemiology

  • Abstract Epidemiological data describing the prevalence of blindness and visual impairment in Haiti are sparse. The Haitian National Committee for the Prevention of Blindness (CNPC) estimates the prevalence of blindness at 1 %.[ncbi.nlm.nih.gov]
  • CONCLUSION: This study proved that RAAB methodology can be successfully conducted in industrialized countries, which often lack reliable epidemiologic data.[ncbi.nlm.nih.gov]
  • AMD was graded per International ARM Epidemiological Study Group. Subjects underwent detailed ophthalmic exam. VI was defined per the WHO classification.[ncbi.nlm.nih.gov]

Prevention

  • Knowledge of CVI is important in planning preventive measures.[ncbi.nlm.nih.gov]
  • Conclusions: About one-sixth of IADL limitations and one-fifth of social participation restrictions could be prevented by an optimal optical correction. These results underline the importance of eye examinations in older adults to prevent disability.[ncbi.nlm.nih.gov]
  • These major causes of blindness should be considered in future public health and nongovernmental organizations strategies for blindness prevention in Jordan.[ncbi.nlm.nih.gov]
  • PURPOSE: The International Agency for Prevention of Blindness (IAPB) South East Asia region (SEAR) that consists of 11 countries contains 26% of the world's population (1,761,000,000).[ncbi.nlm.nih.gov]
  • Relevant findings help to evaluate whether artificial gravity is an appropriate countermeasure to prevent this seemingly adverse effect of long-duration spaceflight. Copyright 2018 the American Physiological Society.[ncbi.nlm.nih.gov]
