RESUMO
Objetivo: investigar a percepção do peso corporal e as dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos. Metodologia: estudo observacional transversal, com adultos e idosos com deficiência visual em Pelotas/RS, realizado no período de abril a maio de 2023. Foi utilizado um questionário composto de 42 itens. Os dados coletados foram analisados por análise descritiva e analítica, e apresentados como média ± desvio padrão ou percentual. Resultados: a amostra contou com 20 pessoas, predominantemente do sexo feminino e idosas. Em relação ao consumo alimentar, 50% dos participantes consomem feijão, 75% frutas e hortaliças, 50% bebidas adoçadas, biscoitos recheados e doces. Referente à percepção do peso corporal, percebeu-se que a maior parte do grupo sente que está acima do peso adequado e se sentem "insatisfeitos(as)". Sobre as dificuldades encontradas, 85% dos participantes relataram dificuldade extrema para identificar a validade dos alimentos, 70% para comprar alimentos frescos e perecíveis e 40% para usar a faca para cortar e descascar os alimentos. Conclusão: verificou-se que a maior parte do grupo sente que está acima do peso adequado e estão "insatisfeitos(as)" em relação ao peso corporal. Além disso, dependem de outra pessoa para escolher os alimentos a serem comprados, saber o prazo de validade, preparar alimentos que precisam ser porcionados, servir refeições no prato, cortar carnes, descascar vegetais e frutas, utilizar faca, entre outros. Esta dependência pode influenciar diretamente no seu consumo alimentar quando essas pessoas se encontram sozinhas, optando por consumir alimentos industrializados de fácil preparo ou prontos.
Objective: to investigate the perception of body weight and the difficulties encountered by people with visual impairments in acquiring, preparing and consuming food. Methodology: cross-sectional observational study, with adults and elderly people with visual impairment in Pelotas/RS, carried out from April to May 2023. A questionnaire composed of 42 items was used. The collected data were analyzed using descriptive and analytical analysis, and presented as mean ± standard deviation or percentage. Results: the sample included 20 people, predominantly female and elderly. Regarding food consumption, 50% of participants consume beans, 75% fruits and vegetables, 50% sweetened drinks, stuffed cookies and sweets. Regarding the perception of body weight, it was noticed that the majority of the group feels that they are overweight and feel "dissatisfied". Regarding the difficulties encountered, 85% of participants reported extreme difficulty in identifying the expiration date of food, 70% in purchasing fresh and perishable foods and 40% in using a knife to cut and peel food. Conclusion: it was found that the majority of the group feels that they are overweight and are "dissatisfied" with their body weight. Furthermore, they depend on someone else to choose the food to be purchased, know the expiration date, prepare food that needs to be portioned, serve meals on the plate, cut meat, peel vegetables and fruits, use a knife, among others. This dependence can directly influence their food consumption when these people are alone, choosing to consume easily prepared or ready-made processed foods.

Structural equation model was used to analyze the effects of visual impairment and resilience and the mediating role of negative emotions. @*Results@#Totally 2 997 middle-aged and elderly populations were enrolled, with the median age of 50.00 (interquartile range, 47.00) years. There were 1 320 males (44.04%) and 1 677 females (55.96%), 1 627 illiterate persons (54.29%), and 2 780 married persons (92.76%). The scores of visual impairment, negative emotions and resilience were (6.79±2.59), (6.35±3.05) and (33.38±10.41) points, respectively. The results of structural equation model analysis showed that after adjusting for age, gender, educational level and marital status, visual impairment had a direct negative positive effect on resilience, with a direct effect value of -0.157 (95%CI: -0.177 to -0.137), and visual impairment could also negatively affect residence through negative emotions, with a mediating effect value of -0.112 (95%CI: -0.126 to -0.104), and the mediating effect contributed 41.64% to the total effect.@*Conclusion@#visual impairment could reduce residence directly or indirectly through the mediating effect of negative emotions among middle-aged and elderly populations.
RESUMO
ObjectiveTo analyze the psychological resilience characteristics of visually impaired adolescents. MethodsFrom February to May, 2023, 13 visually impaired adolescents (average age of 16.5 years) from Nanjing Normal University of Special Education, Yangzhou Special Education School and Nanjing School for the Blind in Jiangsu, China were selected for semi-structured interviews with phenomenological method, and the interview data were sorted by theme analysis method. ResultsFour themes and twelve sub-themes were obtained; namely multiple sources of difficulties, including travel difficulties, learning difficulties, social difficulties and difficulties in daily life; need for external support, including insufficient family support, school support needs to be improved, need for peer support and insufficient social support; negative and positive adaptation coexist, including negative adaptation and positive adaptation; and negative coping and positive coping coexist, including positive coping and negative coping. ConclusionThe psychological resilience of visually impaired adolescents is characterized by multiple sources of difficulties, insufficient external support, coexistence of positive and negative adaptation, and coexistence of positive and negative coping. A joint family-school-society support system should be formed to reduce the source of their difficulties, and help them establish positive adaptation and positive coping methods, to enhance their psychological resilience.
RESUMO
RESUMO: Mesmo com o grande avanço em relação à inclusão de educandos Público da Educação Especial (PEE) em classes comuns, sobretudo a partir do ano de 2000, ainda há barreiras que dificultam a permanência desses educandos em ambientes de aprendizagem, como a falta de formação de professores e de materiais condizentes às suas reais necessidades. Nesse sentido, esta pesquisa teve como objetivo reunir e sistematizar, por meio de uma revisão de literatura, materiais acessíveis de Matemática para educandos com deficiência visual, a fim de auxiliar educadores no preparo de aulas mais acessíveis a esse público. A análise dos dados foi realizada com o auxílio do software Iramuteq. Ao todo foram encontrados 26 trabalhos, entre artigos, teses e dissertações produzidos entre 2012 e 2022, que desenvolveram e aplicaram materiais acessíveis à educandos com deficiência visual na Educação Básica. Os resultados apontam que, além da baixa produção de materiais nos últimos anos, os trabalhos se concentram nos anos finais do Ensino Fundamental e no Ensino Médio, e os tópicos mais abordados referem-se às unidades temáticas de Geometria e Álgebra. Identificou-se, assim, um déficit de materiais para a Educação Infantil e para os anos iniciais do Ensino Fundamental, além da pouca produção para outras unidades temáticas da Matemática.
ABSTRACT: Even with advances related to the inclusion of the Target Group of Learners of Special Education in common classes, especially since 2000, there are still barriers that make the permanence of these students in learning environments difficult, such as the lack of teacher training and materials suited to their real needs. In this regard, this research aimed to gather and systematize, through a literature review, accessible Mathematics materials for students with visual impairments, in order to assist educators in preparing classes that are more accessible to this audience. Data analysis was performed using the Iramuteq software. In total, 26 works were found, including articles, Ph.D. dissertations and Master's thesis produced between 2012 and 2022, that developed and applied accessible materials to students with visual impairments in Basic Education. The results point out that, in addition to the low production of materials over the past years, the pieces of work are focused on the final grades of Elementary School and High School, and the most covered topics refer to the thematic units of Geometry and Algebra. Thus, a deficit of materials for Early Childhood Education and the initial grades of Elementary Education was identified, in addition to the little production for other Mathematics thematic units.
RESUMO
A proptose do globo ocular é uma das consequências comuns do trauma e a enucleação é um procedimento de escolha em caso de impossibilidade de reversão do quadro. Nota-se a infrequência de relatos de enucleação do globo ocular resultante de proptose traumática, o que torna importante a descrição deste caso, a qual objetiva fornecer relevantes informações e contribuições para o desenvolvimento da oftalmologia e clínica cirúrgica veterinária. Uma cadela filhote foi atendida no HVU - UFPI/CPCE, apresentando o globo ocular direito prolapsado. A enucleação foi selecionada em decorrência do intervalo prolongado entre a detecção da lesão e a busca por assistência médica, da presença de uma alta carga de corpos estranhos observados e da ausência de reflexos pupilares. A cirurgia iniciou-se com a cantotomia seguida da dissecação da musculatura do globo ocular. Foi realizado o pinçamento dos vasos sanguíneos e do nervo óptico, e fez-se a ressecção do globo ocular. Depois de uma ligadura invaginante e redução do espaço morto, removeu-se as bordas palpebrais e realizou-se a blefarorrafia. Cerca de 40 dias após a enucleação, a cadela apresentou-se estável e com uma evolução cicatricial satisfatória do ferimento cirúrgico. Esse procedimento, foi realizado de forma semelhante ao que é visto na literatura, embora, majoritariamente, seja recomendada a enucleação em decorrência de afecções diferentes da proptose traumática.
Proptosis of the eyeball is one of the common consequences of trauma and enucleation is the procedure of choice if it is impossible to reverse the condition. There are few reports of enucleation of the eyeball resulting from traumatic proptosis, which makes it important to describe this case, which aims to provide relevant information and contributions to the development of ophthalmology and veterinary surgical practice. A female puppy was seen at the HVU - UFPI/CPCE, presenting with a prolapsed right eyeball. Enucleation was selected due to the prolonged interval between detecting the lesion and seeking medical assistance, the presence of a high foreign body burden and the absence of pupillary reflexes. Surgery began with canthotomy followed by dissection of the eyeball muscles. The blood vessels and optic nerve were clamped and the eyeball was resected. After an invaginating ligature and reduction of the dead space, the eyelid edges were removed and blepharorrhaphy was performed. Around 40 days after enucleation, the dog was stable and had satisfactory healing of the surgical wound. This procedure was carried out in a similar way to that seen in the literature, although enucleation is mostly recommended for conditions other than traumatic proptosis.

Existen pocos relatos de enucleación del globo ocular resultante de proptosis traumática, lo que torna importante la descripción de este caso, que pretende proporcionar informaciones relevantes y contribuciones para el desarrollo de la oftalmología y de la práctica quirúrgica veterinaria. Una cachorra fue atendida en el HVU - UFPI/CPCE con prolapso del globo ocular derecho. Se optó por la enucleación debido al prolongado intervalo entre la detección de la lesión y la búsqueda de asistencia médica, la presencia de una elevada carga de cuerpo extraño y la ausencia de reflejos pupilares. La cirugía comenzó con una cantotomía seguida de la disección de los músculos del globo ocular. Se pinzaron los vasos sanguíneos y el nervio óptico y se resecó el globo ocular. Tras una ligadura invaginante y la reducción del espacio muerto, se retiraron los bordes de los párpados y se realizó una blefarorrafia. Unos 40 días después de la enucleación, el perro estaba estable y la herida quirúrgica había cicatrizado satisfactoriamente. Este procedimiento se llevó a cabo de forma similar a lo visto en la bibliografía, aunque la enucleación se recomienda sobre todo para afecciones distintas de la proptosis traumática.
RESUMO
Background: Hearing-impaired learners with refractive problems require correction because poor vision hinders their development and educational pursuits. Objectives: To determine the level of compliance with spectacle wear in learners with hearing impairment in Ghana. Method: A descriptive cross-sectional study design was used to investigate the level of compliance with spectacle wear in hearing-impaired learners with uncorrected refractive errors (URE). The participants were from six schools for the hearing impaired, comprising three schools from each sector (Northern and Southern) of Ghana. Results: Of the 1914 learners screened, 69 (3.61% CI: 2.824.54%) had URE. Sixty-two (89.9%) learners with URE had myopia (-0.50 Dioptre Sphere (DS) to -2.00DS), and 7 (10.1%) had hyperopia (+2.00DS to +10.00DS). There were more females (53.6%) with URE than males, and their ages ranged from 8 to 35 years, with a mean of 17.35 ± 5.19 years. Many (56.5%) learners complied with spectacle wear after 3 months of reassessment, with females being more compliant than males, but the difference was not significant (p = 0.544). Learners who complied well with the spectacle wear were those with moderate visual impairment (VI), followed by mild VI, while those with no VI were the least compliant. A significant difference was observed between spectacle compliance and presenting VI (p = 0.023). Conclusion: The spectacle wear compliance level was high compared to a previous study (33.7%) in Ghana. Contribution: This study highlights the importance of addressing URE among learners with hearing impairment in Ghana and Africa.

RESUMO
Purpose: To document the spectrum and magnitude of eye disorders and visual impairment in the Dongaria—a Particularly Vulnerable Tribal Group in the Rayagada district of Odisha, India. Methods: A door?to?door screening protocol included a record of basic health parameters, visual acuity for distance, and near and flashlight examination of the eyes. Spectacles were dispensed to those who improved; those who failed the screening were referred to fixed (primary and secondary) eye care centers. Results: We examined 89% (n = 9872/11,085) of people who consented for screening. The mean age was 25.5 ± 18.8 years; 55% (n = 5391) were female; 13.8% (n = 1361) were under?five children, and 39% (n = 3884) were 6 to 16 years. 86% (n = 8515) were illiterate. 12.4% (n = 1224) were visually impaired, of which 9.9% had early moderate VI, and 2.5% had severe VI and blindness. Uncorrected refractive error was detected in 7.5% (n = 744) and cataracts in 7.6% (n = 754); among the adults, 41.5% (n = 924/2227) had presbyopia. In children, 20% (n = 790) had vitamin A deficiency, 17% (n = 234) had global acute malnutrition, and 18% (n = 244) were stunted for their age. Almost two?thirds (62%, n = 6144) confirmed habitual intake of alcohol, and 4% (n = 389) of adults had essential hypertension. Following the screening, 43.5% (n = 837) of referred patients reported to the fixed centers, and 55% (134/243) of people advised underwent cataract surgery. Spectacles were dispensed to 1496 individuals. Conclusion: Visual impairment and malnutrition are high in Dongaria indigenous community. Permanent health facilities and advocacy would improve this community’s health and health?seeking behavior.
RESUMO
Purpose: Indian fishermen belong to a marginalized population and are continuously exposed to extreme occupational hazards and sunlight. A high prevalence of visual impairment (VI) is reported in the coastal fishing community. We aimed to investigate the association between VI and sunlight exposure measurement (SEM). Methods: In this cross?sectional observational study, 270 eyes of 135 participants were enrolled from a coastal fishing village. Participants underwent a comprehensive ophthalmic examination, which included best?corrected visual acuity (BCVA), and anterior and posterior segment examination. Ocular Surface Disease Index (OSDI) and SEM questionnaire were administered to estimate the level of dry eye and ultraviolet?B (UV?B) exposure, respectively. VI was defined as presenting visual acuity worse than 6/12 (logarithm of the minimum angle of resolution [logMAR] > 0.3). Results: The mean age and spherical equivalent were 50.56 ± 11.72 years (range: 18–80 years) and 0.36 ± 1.68 diopters (D) (range: ?7.0 to +3.0 D), respectively. Age, SEM, OSDI, fishing as an occupation, and cataract were significantly associated with higher odds of VI in univariate analysis. Refraction, gender, education level, smoking status, amblyopia, systematic, and other ocular diseases were not significantly associated with VI. In the multivariate analysis, age, SEM, and presence of cataract remained significantly associated with a higher risk for VI. The area under the receiver operating characteristic curve values for age and SEM scores demonstrate a fair index of discrimination for the detection of VI. Conclusion: SEM level is directly associated with a higher risk of VI among fishermen. The fishing community might benefit from regular eye examinations and awareness about the harmful effects of sunlight exposure and preventive measures.
RESUMO
Resumen Antecedentes: Los datos sobre discapacidad visual (DV) en pacientes con diabetes son necesarios para orientar los recursos económicos y humanos que disminuyan su prevalencia. Objetivo: Estimar la prevalencia de DV relacionada con retinopatía diabética en pacientes con diabetes tipo 2 en un entorno hospitalario. Material y métodos: Estudio transversal realizado de 2014 a 2019 en una consulta externa de oftalmología. Cualquier DV se definió como agudeza visual corregida con agujero estenopeico en el ojo con mejor visión (≥ 0.24 logMAR). Se evaluó la presencia de retinopatía diabética, edema macular diabético (EMD) y cataratas. Resultados: Se incluyeron 840 pacientes; la mediana de duración de la diabetes fue de 15 años. La prevalencia de DV fue de 30 %. Se encontró retinopatía diabética en 62 % (30 % tenía retinopatía diabética que amenazaba la visión [RDAV]); 17 %, EMD y 3 %, cataratas. La razón de momios para DV moderada o de mayor gravedad fue de 9.02 para RDAV (p < 0.001), 5.89 para EMD referible (p = 0.001) y 2.51 para catarata (p = 0.006). Conclusión: Treinta por ciento de los participantes tenía algún grado de DV. La DV moderada o de mayor gravedad mostró una fuerte asociación con RDAV y EMD referible.
Abstract Background: Data on visual impairment (VI) in patients with diabetes are necessary in order to guide economic and human resources for reducing its prevalence. Objective: To estimate the prevalence of diabetic retinopathy-related VI in patients with type 2 diabetes in a hospital-based setting. Material and methods: Cross-sectional study carried out from 2014 to 2019 in an ophthalmology outpatient clinic. Any VI was defined as corrected pin-hole visual acuity in the better eye of ≥ 0.24 logMAR. The presence of diabetic retinopathy (DR), diabetic macular edema (DME) and cataract was evaluated. Results: A total of 840 patients were included; median diabetes duration was 15 years. The prevalence of VI was 30 %. DR was found in 62 % of patients (30 % had sight-threatening DR [STDR]), 17 % had referable DME, and 3 %, cataracts. The odds ratio for moderate or worse VI was 9.02 for STDR (p < 0.001), 5.89 for referable DME (p = 0.001), and 2.51 for cataract (p = 0.006). Conclusion: Thirty percent of participants had some degree of VI. Moderate or worse VI showed a strong association with STDR and referable DME.
RESUMO
Purpose: Coronavirus disease 2019 (COVID?19) pandemic affected the in?person rehabilitation/habilitation services in families with children with cerebral visual impairment (CVI) in India. This study aimed to develop a structured and family?centered telerehabilitation model alongside conventional in?person intervention in children with CVI to observe its feasibility in the Indian population. Methods: This pilot study included 22 participants with a median age of 2.5 years (range: 1–6) who underwent a detailed comprehensive eye examination followed by functional vision assessment. The visual function classification system (VFCS) was administered to the children and the structured clinical question inventory (SCQI) to the parents. Every participant underwent 3 months of telerehabilitation including planning, training, and monitoring by experts. At 1 month, the parental care and ability (PCA) rubric was administered to the parents. After 3 months, in an in?person follow?up, all the measures were reassessed for 15 children. Results: After 3 months of Tele?rehabilitation there were significant improvements noted in PCA rubric scores (P<0.05). Also, statistically significant improvements were noted in functional vision measured using SCQI and VFCS scores (P<0.05) compared to baseline. Conclusion: The outcomes of the study provide the first steps towards understanding the use of a novel tele?rehabilitation model in childhood CVI along?side conventional face?to?face intervention. The added role of parental involvement in such a model is highly essential.
RESUMO
Purpose: To assess the incidence, visual impairment, and blindness due to retinitis pigmentosa (RP) in a rural southern Indian cohort. Methods: This is a population?based longitudinal cohort study of participants with RP from the Andhra Pradesh Eye Disease Study (APEDS) cohorts I and III, respectively. The study included participants with RP of APEDS I who were followed until APEDS III. Their demographic data along with ocular features, fundus photographs, and visual fields (Humphrey) were collected. Descriptive statistics using mean ± standard deviation with interquartile range (IQR) were calculated. The main outcome measures were RP incidence, visual impairment, and blindness as per the World Health Organization (WHO) definitions. Results: At baseline (APEDS I), 7771 participants residing in three rural areas were examined. There were nine participants with RP with a mean age at baseline of 47.33 ± 10.89 years (IQR: 39–55). There was a male preponderance (6:3), and the mean best?corrected visual acuity (BCVA) of 18 eyes from nine participants with RP was 1.2 ± 0.72 logarithm of minimum angle of resolution (logMAR; IQR: 0.7–1.6). Over a mean follow?up duration of 15 years, 5395/7771 (69.4%) were re?examined, which included seven RP participants from APEDS 1. Additionally, two new participants with RP were identified; so, the overall incidence was 370/ million in 15 years (24.7/million per year). The mean BCVA of 14 eyes of seven participants with RP who were re?examined in APEDS III was 2.17 ± 0.56 logMAR (IQR: 1.8–2.6), and five of these seven participants with RP developed incident blindness during the follow?up period. Conclusion: RP is a prevalent disease in southern India that warrants appropriate strategies to prevent this condition.
RESUMO
Aim: Visual impairment is a public health problem globally. This study aimed to determine the prevalence and pattern of visual impairment among adult population in Mangu Local Government Area (L.G.A), Plateau State, Nigeria.Study Design: A population-based descriptive cross-sectional survey of 802 adult population aged 18 years and above was conducted in Mangu L.G.A, Plateau State, Nigeria using a multi-stage cluster random sampling design.Methodology: Subjects were evaluated using a magnifying loupe, Snellen E chart, direct ophthalmoscope and torchlight. Vision status was defined using World Health Organization categories of visual impairment based on presenting visual acuity (VA).Results: Out of a total of 960 respondents enumerated for the study, 802 (83.5%) adults participated. Prevalence of blindness (presenting VA of less than 3/60 in the better eye) was 8.1%; prevalence of low vision (presenting VA of at least 3/60 but less than 6/18 in the better eye) was 27.6%; prevalence of overall visual impairment (presenting VA less than 6/18 in the better eye) was 35.7%. Prevalence of visual impairment was higher in males (40.8%) than in females (34.9%), although not statistically significant (p=0.098). Prevalence of blindness and impaired vision increased significantly with increasing age, from 21.7% at 20 - 39 years to 83.6% among those aged ?80 years (P < 0.001).Conclusion: Much can be done by individuals, governments and non-governmental organizations to reduce so much blindness and vision loss through cost-effective interventions such as wears of sunglasses and other preventive measures to prevent ultraviolet radiation effect on their eyes.
RESUMO
Background: Uncorrected refractive error is one of the leading causes of visual impairment and blindness world-over. The distribution and pattern of presentation is variable depending on various factors. Regardless of the type, refractive errors are easily correctable with spectacles if diagnosed early.Objective: The objective of this study was to evaluate the pattern of refractive errors among medical students at University of Zambia - School of Medicine.Methodology: This was a cross-sectional study conducted at the University Teaching Hospitals-Eye Hospital involving Master of Medicine, Master of Surgery (MBChB) students from third to seventh year of study at University of Zambia - School of Medicine, Ridgeway campus between October 2021 and March 2022. A total of 210 participants were recruited in the study. Subjects had non-cycloplegic autorefraction combined with a researcher administered questionnaire. Spherical equivalents (SE) ? - 0.50D were determined as myopia; SE of ? + 0.50D hyperopia and ? -0.50D cylinder as astigmatism. Statistical analysis was carried out using Stata version 13.0.Results: One hundred and forty-one (67.1%) subjects had a form of refractive error; 56.0%, 31.2% and 12.8% of them were astigmats, myopes or hyperopes, respectively. The prevalence of ametropia was 65.0 % in females and 69.0 % in males. Minus spherical errors ranged from -0.25 to -5.00D and plus spherical errors ranged from +0.25 to +3.00D. The mean spherical equivalent for the group was -0.45D. Parental history of refractive error was significantly associated with diagnosis of refractive error (p=0.001) while age and gender were not (p = 0.428 and 0.530, respectively). The majority (68.6%) of participants were not aware of their refractive error.Conclusion: The prevalence of refractive errors among medical students was high, with astigmatism being the most common type. The majority of those found with refractive error were not aware of the diagnosis.
RESUMO
Introduction: Determinants of health are divided into four types, such as “Biological-Psychological-Environmental-Social Determinants”. The social determinants of health include gender disparities, economic status, ethnicity, race, geographic isolation, or having a specific health condition. Moreover, the social deter-minants are interdependent and interrelated with one another. There can also be a primary determinant that affects the other determinants. For example, educational level of the patients is associated with knowledge and awareness of eye care and its conditions. However, education might have a different effect than income in should be access of eye care when needed. Methodology: The study is mainly dependent on secondary data analysis. Results: The primary objective of the study is to illustrate the sociological aspects of visual impairment-related inequities and to identify the social determinants of visual impairments and disparities in India. An-other aim of the paper is to present a deeper understanding of how inequities impact the incidence of visual impairment and blindness based on the social determinants of health. The present study adopts the ecological and Commission on Social Determinants of Health (CSDH) framework 2008. We reaffirm the fact that inequi-ties negatively affect the visual impairment and blindness conditions. The national health policies should take into account the social determinants of visual impairment in their policies relating to comprehensive eye care. Social and economic factors are connected with health and welfare; those socio-economic inequalities con-tribute to health inequalities. For reducing the health inequalities around the world, we need effective policy implementation and proper fund pools. Furthermore, committed action on societal determinants of health, sufficient human resources are also necessary to control the health disabilities, include visual impairment

Purpose: This study was conducted to estimate the visual acuity improvement in patients with Leber hereditary optic neuropathy (LHON) with the help of low vision devices (LVDs) and to analyze the types of distant and near LVDs prescribed to the patients with LHON. Methods: A retrospective case review of 74 subjects with LHON who were referred to a low vision care clinic at a tertiary eye center from 2016 to 2019 were recruited. The reason for referral was assessed from the patients’ electronic medical records (EMR). Demographic data of the patients, visual acuity status, type of LVD prescribed, and visual acuity improvement with LVD were documented. Results: Out of 74 patients, 91.9% (n = 68) were male, and the median age of patients was 21 (16) years. A 4× monocular telescope was prescribed for 2.7% of patients (n = 2) and SEETV binocular telescope for 1.4% (n = 1) was advised for distance. The most commonly prescribed near LVD was the 6× cutaway stand magnifier for 22 patients (29.7%). Four patients (5.4%) were prescribed with Notex, the most commonly prescribed non?optical LVD. Niki CCTV (12.2%, n=9) was the most commonly prescribed assistive device. The subjects were divided into three groups based on age: group I consisted of those <18 years of age, group II 18–40 years, and group III >40 years for the interpretation of visual improvement. There was a statistically significant improvement (group I: P < 0.001, group II: P < 0.0001, group III: P < 0.003) in near vision with help of LVDs in all three groups. Conclusion: The use of LVDs and rehabilitation can help patients with LHON to lead a better life and will be more beneficial
RESUMO
Purpose: This study utilized virtual focus group discussions to document the facilitators and barriers reported by the parents as part of the tele?rehabilitation service delivery model in India. Methods: This study included 17 participants who were enrolled into the Tele?rehabilitation program (16 mothers, 1 father) and the virtual focus group discussion (V?FGD) were conducted through a WhatsApp video call. Three V?FGDs were conducted involving two moderators and a note taker. The V?FGD, focused at extracting the perceptions of parents pertaining to facilitators, barriers and coping mechanisms to barriers related to the tele?rehabilitation model. Results: Thematic analysis resulted in four themes for barriers that included: family and support, time, parent and care taker, child and place of living related; facilitators reported included: continuous monitoring, accessibility to professional services, provision of resource materials and parental empowerment. Themes “family and support” and “child” were most reported by parents with children >3 years and ?3 years respectively. Finally, the barriers and facilitators were aligned with the chapters and codes of International Classification of Functioning, children and youth version (ICF?CY) environment and personal factors. Conclusion: This V?FGD highlights the importance of parental?centred and structured Tele?rehabilitation among children with CVI in India. The outcome of this study opens avenues for creating effective intervention.
RESUMO
Purpose: Assistive technology (AT) has recently received considerable attention around the world. Studies have shown poor access to assistive technology for visual impairment (ATVI) in schools for the blind in India. The present article aimed at designing a school?based model to improve AT access in schools and provide hands?on training, and identify types of ocular morbidities present among students. Methods: The vision rehabilitation (VR) team of a tertiary eye?care center visited schools for the blind as a part of community? based VR services. The team conducted a basic eye examination and assessed best?corrected vision acuity (BCVA) and provided VR services. Furthermore, two schools were selected to establish an ATVI learning center as a pilot model. Results: In total, 1887 students were registered for VR and obtained their disability certificates in 2019?20. Retina problems (25.7%), globe abnormalities (25.5%), optic nerve atrophy (13.6%), and squint (12.0%) were common ocular problems identified in students. Around 50.3% of students had BCVA ³ 1/60 in the better eye who would be benefited from visual?based AT, and the remaining students with visual substitution AT. Further, 20.8% of them who had near vision between N18 to N24 would be benefitted from large print books. Two schools were provided ATVI with support from the WHO. Familiarization, demonstration, and initial training for ATVI were carried out. Conclusion: A sizable number of the students would be benefitted from visual?based AT apart from visual substitutions AT. Students were interested to have such ATVI centers in the school for academic and non?academic skills development.
RESUMO
OBJECTIVES@#To study the virtual reality-pattern visual evoked potential (VR-PVEP) P100 waveform characteristics of monocular visual impairment with different impaired degrees under simultaneous binocular perception and monocular stimulations.@*METHODS@#A total of 55 young volunteers with normal vision (using decimal recording method, far vision ≥0.8 and near vision ≥0.5) were selected to simulate three groups of monocular refractive visual impairment by interpolation method. The sum of near and far vision ≤0.2 was Group A, the severe visual impairment group; the sum of near and far vision <0.8 was Group B, the moderate visual impairment group; and the sum of near and far vision ≥0.8 was Group C, the mild visual impairment group. The volunteers' binocular normal visions were set as the control group. The VR-PVEP P100 peak times measured by simultaneous binocular perception and monocular stimulation were compared at four spatial frequencies 16×16, 24×24, 32×32 and 64×64.@*RESULTS@#In Group A, the differences between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at 24×24, 32×32 and 64×64 spatial frequencies were statistically significant (P<0.05); and the P100 peak time of normal vision eyes at 64×64 spatial frequency was significantly different from the simulant visual impairment eyes (P<0.05). In Group B, the differences between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at 16×16, 24×24 and 64×64 spatial frequencies were statistically significant (P<0.05); and the P100 peak time of normal vision eyes at 64×64 spatial frequency was significantly different from the simulant visual impairment eyes (P<0.05). In Group C, there was no significant difference between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at all spatial frequencies (P>0.05). There was no significant difference in the P100 peak times measured at all spatial frequencies between simulant visual impairment eyes and simultaneous binocular perception in the control group (P>0.05).@*CONCLUSIONS@#VR-PVEP can be used for visual acuity evaluation of patients with severe and moderate monocular visual impairment, which can reflect the visual impairment degree caused by ametropia. VR-PVEP has application value in the objective evaluation of visual function and forensic clinical identification.
