Main Factor

In music listening, limitations on visual experience affect a listener’s abstract information processing and conceptualization of the music. The aim of this study is to examine the differences in emotional responses to music between adults with visual impairment (VI) and adults with normal vision (NV). By using specific, emotion-inducing music reflecting happiness, sadness, anger, and fear, this study considers factors such as music emotion identification, emotional valence, arousal, intensity, and musical preference. A total of 120 participants (60 VI and 60 NV) listened to sixteen 15-second music excerpts and reported which emotion and to what extent they perceived it, using a self-reported music emotion evaluation scale. The results indicated that both of the groups showed high congruence in music emotion identification. However, the VI group showed significantly higher arousal, intensity and preference for sadness, while showing the lowest score for the intensity of fear. The main factor affecting emotion identification was preference for the VI group, and valence for the NV group.

<p class="0abstract">The issue of lacking reference books in braille in most public building is crucial, especially public places like libraries, museum and others. The visual impairment or blind people is not getting the information like we normal vision do. Therefore, a multi languages reading device for visually impaired is built and designed to overcome the limitation of reference books in public places. Some research regarding current product available is done to develop a better reading device. This reading device is an improvement from previous project which only focuses on single language which is not suitable for public places. This reading device will take a picture of the book using 5MP Pi camera, Google Vision API will extract the text, and Google Translation API will detect the language and translated to desired language based on push buttons input by user. Google Text-to-Speech will convert the text to speech and the device will read out aloud in through audio output like speaker or headphones.   A few testings have been made to test the functionality and accuracy of the reading device. The testings are functionality, performance test and usability test. The reading device passed most of the testing and get a score of 91.7/100 which is an excellent (A) rating<strong>.</strong></p>

Abstract Aims  The associations of visual impairment (VI) with cardio-metabolic risk factors have been reported but its association with cardiovascular mortality remains uncertain. Therefore, we evaluated the association of visual acuity (VA) with overall, injury-related, and cardiovascular mortality. Methods and results A cohort study was performed in 580 746 Korean adults (average age, 39.7 years) who were followed for a median of 8.1 years (maximum, 16 years). Presenting VA was measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Visual acuity in the better vision eye was categorized as normal vision (≥0.8), lowered vision (0.5–0.8), mild visual impairment (VI) (0.3–0.5), or moderate to severe VI (&lt;0.3). Vital status and cause of death were ascertained through linkage to national death records. During 4 632 892.2 person-years of follow-up, 6585 overall deaths, 974 cardiovascular deaths, and 1163 injury-related deaths were identified. After adjustment for possible confounders, the multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for overall mortality among participants with lowered vision, minimal VI, and moderate to severe VI were 1.21 (1.13–1.29), 1.26 (1.15–1.37), and 1.54 (1.40–1.68), respectively, compared with those with normal vision. The corresponding HRs (95% CIs) for injury-related mortality were 1.12 (0.96–1.32), 0.98 (0.76–1.26), and 1.36 (1.04–1.79), respectively, and the corresponding HRs (95% CIs) for cardiovascular mortality were 1.32 (1.12–1.57), 1.43 (1.15–1.77), and 2.41 (1.94–2.99). Conclusion  In this large cohort of young and middle-aged individuals, VI was associated with increased risk of mortality especially due to cardiovascular disease.

Ocular Infections

Bacteria are the major contributor of ocular infections worldwide. This can damage the structures of the eye with possible blindness and visual impairments, if left untreated. This study was undertaken   to determine bacterial agents of conjunctivitis among individuals from onchocerciasis endemic area in Anambra State, Nigeria. This was a cross-sectional study involving ninety-two (92) randomly recruited  test  subjects  undergoing ivermectin therapy aged between 11-80 years with signs and symptoms of  onchocerciasis infection and bacterial conjunctivitis at Isu-Anaocha community in  Anambra state between October and November, 2016. Ninety-two (92) apparently healthy subjects without signs and symptoms of onchocerciasis and bacterial conjunctivitis with normal vision, within the age of 11-80 years from the same community were used as control subjects, making a total of 184 participants. Visual acuity test was conducted on the participants using Snellen’s alphabet chart and illiterate E   chart.  Phenotypic   and antibiotic susceptibility tests of these isolates were   carried out according to  Kirby - Bauer disc diffusion method guidelines. In the test group, 22 out of 92 conjunctival samples yielded bacterial growth, giving percentage prevalence of 23.9%, with age group 41-50 years having the highest frequency 7(31.8%) among individuals co-infected with onchocerciasis infection whereas 72 out of 92 conjunctival samples in the control group yielded bacterial growth giving percentage prevalence of 78.3%, with age group 41-50 years having the highest frequency 35(37.2%) among individuals that had  no signs and symptoms of onchocerciasis infection. The predominant bacteria isolated was Staphylococcus   aureus 8(36%) in the test group and 20 (28%) in the control group, giving a total of 28 (30%). Other bacterial isolates were Streptococcus pneumoniae 17 (18%), Staph. epidermidis 15 (16%), Escherichia coli 13(14%), Pseudomonas aeruginosa 12(13%) and Salmonella spp. 9(9%). Antibiotic susceptibility testing showed that Gentamicin and fluoroquinolones are most active against Gram positive bacteria in conjunctivitis while Augmentin was found to be the most active against Gram negative organisms, therefore, recommended as first line drug. Visual acuity (VA) test done on the test group showed that 52 (57%) persons had   normal vision, 20 (22%) had mild visual impairment, 15 (16%) had moderate visual impairment, 5(5%) had severe visual impairment but none was blind. All forms of visual impairment are not wholly attributable to bacterial conjunctivitis as some could be due to ageing and uncorrected refractive errors.

Functional Changes

Aniridia affects many visual aspects of one’s life. This chapter will highlight many of these effects. Functional changes that occur due to aniridia will be discussed. Once the patient’s vision is assessed and goals are established with a thorough eye examination, numerous avenues can be taken to ensure the support of all the patient’s health care providers. Referrals can be made to appropriate professionals to ensure full understanding and management of the ocular condition. Visual acuity is the measurement used to determine vision levels. Normal vision is 20/20, which means that what a normal person sees at 20 feet, the patient sees at 20 feet. If their vision is 20/40, they would need to be at a distance of 20 feet to see what someone with normal vision can see at 40 feet. The decrease in visual acuity in those with aniridia usually ranges from under 20/60 to as low as approximately 20/400. This is due to the lack of development of the macular area, or fovea. The fovea is responsible for our clearest, most precise vision. Those with visual acuity of 20/200 or worse that is best corrected while wearing spectacles or contact lenses in the better-seeing eye are considered legally blind. While most people who suffer from aniridia are not legally blind, they are visual impaired. Visual impairment is defined as visual acuity of 20/70 in the better-seeing eye when optimally corrected with glasses or contact lenses. The designation of “visual impairment” also has a functionality factor. If a person has a reduction in the ability of the eye or the visual system to perform to a normal ability, he/she is considered visually impaired. Visual field is the measurement of peripheral vision. Those with aniridia may have decreased peripheral vision. This is not directly due to aniridia, but rather to glaucoma, which may develop due to structural changes in the eye. Glaucoma is explained in detail in the glaucoma chapter of this book.

A test of the strength of children's hip and knee extensors found that children who were congenitally blind or had low vision had weaker knee extensors than did sighted children, but that after the correction for lean body weight (LBW), these differences were not significant. The children who were blind or had low vision also had weaker hip extensors, but after LBW correction, only the blind children's hip extensors were weaker than those of the children with normal vision. The findings indicate that congenitally blind children may be prone to develop weak leg extensors because of poor body build or the constraints of blindness and that they require extensive physical intervention during infancy.

Objective: To determine the prevalence of mild visual impairment (MVI) among urban older adults in primary care settings, and ascertain whether MVI was a risk factor for inadequate performance on self-care health tasks. Method: We used data from a cohort of 900 older adults recruited from primary care clinics. Self-management skills were assessed using the Comprehensive Health Activities Scale, and vision with corrective lenses was assessed with the Snellen. We modeled visual acuity predicting health task performance with linear regression. Results: Normal vision was associated with better overall health task performance ( p = .004). Individuals with normal vision were more likely to recall health information conveyed via multimedia ( p = .02) and during a spoken encounter ( p = .04), and were more accurate in dosing multi-drug regimens ( p = .05). Discussion: MVI may challenge the performance of self-care behaviors. Health care systems and clinicians should consider even subtle detriments in visual acuity when designing health information, materials, and devices.
