Our objective is to enable the blind to use smartphones with touchscreens to make calls and to send text messages (sms) with ease, speed, and accuracy. We believe that with our proposed platform, which enables the blind to locate the position of the keypads, new games and education, and safety applications will be increasingly developed for the blind. This innovative idea can also be implemented on tablets for the blind, allowing them to use information websites such as Wikipedia and newspaper portals.

INTRODUCTIONThe objectives of this study were to assess the utility and validity of the self-administered SF-36 and the effect of visual or cognitive impairment on these measures in an older population.

MATERIALS AND METHODSAttempt rates, completion rates and internal consistency (Cronbach alpha) were compared within the second cross-sectional, population-based Blue Mountains Eye Study (n = 3509, mean age 66.7 years, 57% women).

RESULTSThe SF-36 was attempted by 3162 (90.1%) participants, of which 2470 (78.1%) completed all items and 2873 (90.9%) completed sufficient items for calculation of all dimensions. In a multivariate model adjusting for age, sex, and presenting visual and cognitive impairments, women (P = 0.011) and participants with visual or cognitive impairments (P < 0.0001) were less likely to attempt the questionnaire. Completion rates were significantly lower with increasing age (P < 0.0001), in men (P < or = 0.0005) and in those with cognitive impairment (P < 0.0001). A high level of internal consistency (Cronbach alpha > 0.85 for all dimensions) and construct validity was demonstrated, the latter distinguishing between those with and without medical conditions, disabilities or recent hospital admissions (P < 0.01). As the prevalence of visual or cognitive impairment was relatively low in this population, we found no apparent effect of these impairments on the validity of SF-36.

CONCLUSIONSAttempt and completion rates, but not internal consistency and construct validity, of the SF-36 were influenced by age, gender, and presenting visual and cognitive impairments. The overall high attempt and completion rates, internal consistency and construct validity suggest that the self-administered SF-36 is a suitable healthrelated quality of life (HRQOL) measure in similar older community-living populations.

Visually impaired people face many inconveniences because of the loss of vision. Therefore, scientists are trying to design various guidance systems for improving the lives of the blind. Based on sensory substitution, auditory guidance has become an interesting topic in the field of biomedical engineering. In this paper, we made a state-of-technique review of the auditory guidance system. Although there have been many technical challenges, the auditory guidance system would be a useful alternative for the visually impaired people.

This cross sectional study was conducted in the city of Taiz, Yemen, during the period from August 2006 to August 2007 in order to investigate the seroprevalence and incidence of toxoplasmosis among apparently healthy children (AHC) and visually and/or hearing disabled children (DC). The seroprevalence was 16.0% among AHC compared to 32.5% among DC. The effect of gender was clear as the seroprevalence rate was significantly higher among females (18.3 and 43.8% for AHC and DC, respectively) than males (13.8 and 25% for AHC and DC, respectively). The seroprevalence was proportionally increased with the age, and the highest rates (20.9 and 53.0%) were reported among the oldest age group (> 10-14 years) for AHC and DC groups, respectively. The incidence rate was also higher (4.2%) in DC group compared to AHC group (2.4%) during 1 year period. These data indicate that the seroprevalence and incidence of toxoplasmosis are significantly higher in DC group than those of AHC group. We need to check further relationship between toxoplasmosis and visual and/or hearing disability.

OBJECTIVE: To identify the avoidable causes of childhood blindness and visual impairment in a school of the blind in the Philippines.

METHODS: The medical records of students enrolled at the Resources for the Blind early intervention and preschool program from 1999 to 2012 were reviewed. Demographic characteristics and causes of visual disability were abstracted and tabulated.

RESULTS: A total of 90 records were included in the study. Eighty six (76.7%) had visual acuity classified as blind (<20/400) or severe visual impairment (<20/200 - 20/400, 18.9%). Majority (69.8%) were below 6 years of age and most (44.2%) were below 1 year. Retinopathy of prematurity was the most common cause (47.7%), followed by retinablastoma (11.6%). Perinatal factors accounted for most of the etiologic causes (58.1%) of visual loss.

CONCLUSION: More than half of the causes of severe visual impairment and blindness were potentially avoidable, with retinopathy of prematurity as the leading etiology.

PURPOSE: Disability is a significant problem and is accepted globally as a health priority in childhood. Like nonvisually impaired children, visually impaired children also need to use health services during childhood. The purpose of this study was to determine the health problems of visually impaired children. METHODS: A descriptive design was used. The subjects were 74 children with visual impairment attending primary school (aged 5e14 years), who agreed to participate and whose parents gave permission. Data were collected via physical examination including questionnaires and a physical assessment form. The health screening included physical measurements for height, weight, blood pressure, dental health, hearing, and scoliosis. RESULTS: The mean age of children was 10.43 +/- 2.9 years. When the health screening results of children were examined, it was found that 25.7% of the children were overweight or obese, 35.1% of them had dental problems, 27.0% had hearing problems, and 39.2% had scoliosis risk. Systolic and diastolic blood pressures were normal in 91.8% and 93.2% of the children, respectively. CONCLUSIONS: These findings showed the important role of school health nurses in performing health screenings directed at visually impaired children who constitute a special group for school health services. Health screening for height, weight, dental health, hearing, and scoliosis is suggested for visually impaired children.

After being introduced to Japan, the Chinese acupuncture and massage therapy has changed a lot, in which the influence aroused by the blind practitioners cannot be ignored. Through analyzing the development and the transition of the blind acupuncture and massage industry in Japan, it is found that the tube needle technique, changeable acupoints concept, technical deviation and the importance on acupoints rather than meridians are still existed commonly today, which are introduced by the blind acupuncture and massage practitioners, the special group in Japan. In the process of development, the interaction with the governmental strategy has played the essential role in the consolidation of the above features.

At present the sight impairment evaluation in forensic medicine of China is based on the international classification of disease by WHO in 1973. The main measured indicator is "best corrected visual acuity". It is different from "presenting distance visual acuity" in some situations. In the new blindness and vision loss classification made by WHO in 2003, "presenting distance visual acuity" took the place of the "best corrected visual acuity". In the practice of forensic medicine, "presenting distance visual acuity" can not reflect the real visual acuity duo to the exaggeration or disguise of the wounded. We suggest to use "the best corrected presenting distance visual acuity" instead of "presenting distance visual acuity" in order to avoid the influences of the exaggeration or disguise of the wounded.

OBJECTIVETo determine the prevalence of ocular trauma and the proportion of blindness and visual impairment due to trauma in a rural population in northern China.

METHODSThe Handan Eye Study is a population-based cross-sectional study that surveyed 6830 Chinese people aged 30+ years from 13 randomly selected villages in Yongnian County, city of Handan, Hebei Province, in July, 2006. All participants underwent a standardized interview and extensive examinations. A structured questionnaire was used to collect information on ocular trauma.

RESULTSOf the 5837 participants who filled out the questionnaire, 124 subjects [2.1%; 95% confidence interval (CI), 1.8%-2.5%] reported a history of ocular trauma in either eye, including 19 (0.3%) persons reporting trauma in both eyes. Men were more likely to have an eye injury than women [odds ratio (OR), 3.3; 2.2-4.9]. In multiple logistic regression models, ocular trauma was significantly more frequent among normotensive participants when compared with hypertensive participants (hypertensive vs. normotensive: OR, 0.6; 0.4-0.9) and among participants who had a history of falls (OR, 2.4; 1.2-4.8). The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5% (13 subjects) and 21.0% (26 subjects), respectively.

CONCLUSIONOur study reports the prevalence of severe ocular trauma among adults in rural China, revealing a high proportion of blindness and visual impairment due to trauma. These findings suggest the need for educational strategies to increase eye health awareness in this rural population with focus on providing at least appropriate first aid care to reduce blindness due to trauma.
