Programa de equoterapia: intervenção com um praticante com deficiência visual

The hippotherapy is a therapeutic and educational method that uses the horse within an interdisciplinary approach in the areas of health, education and riding, seeking the biopsychosocial development of people with disabilities and/or special needs. The method generates the practitioner positive effects, such as physical, social and psychological benefits. The goal of this study was to investigate alterations with a practitioner with visual impairment during their participation in a hippotherapy program. The study is characterized by a qualitative and descriptive research, in the form of case study. Data were collected through interviews with the mother of the practitioner and filming, photographs and systematic observation of the sessions. Improvements were found in the behavior of practicing at home, and there was progress in motor performance, and self-confidence generated by the domain horse. It is concluded that the hippotherapy program generated physical, psychological and social benefits to the practitioner.

Um estudo sobre a intervenção com o professor de educação física para a inclusão educacional do aluno com deficiência visual

It was aimed to identify how the physical education teachers worked to include a student with visual impairment; intervene with the teacher from the identified necessities and assess the intervention. Data were collected in three stages: 1) Weekly monitoring and filming the classes, 2) intervention by the reflection of videos coming from the previous step and suggesting new actions, 3) development of filming for evaluating the intervention. Before the intervention, it was identified that the explanation of the activities happened collectively. It was held the physical help as the first form of instruction, the student with visual impairment participation occurred depending on the company of a classmate who held hands and did the activities together. Along the intervention it was reflected about the structure of the classes, the ways of explanation of the activities and the strategies and the resources to assure an enjoyable participation of students with visual impairments. The training of peer tutors was a strategy used. After the intervention it was identified in the classroom the assistance of the trained peer tutors; the maintenance of oral explanation and demonstration, though, the first way to explanation for the student with visual impairment started to be the oral tip.

Contextos comunicacionales adecuados e inadecuados para la inclusión de alumnos con discapacidad visual en clases de física moderna

This article is inserted in a wider study that seeks to understand the main inclusion barriers in Physics classes for students with visual impairment It aims to understand which communication context favors or impedes the visually impaired student participation to the impairment visual student’s real participation in Modern Physics activities. The research defines, from the empirical-sensory and semantics structures, the languages used in the activities, as well as, the moment and the speech pattern in which those languages have been used. As a result, this study identifies a strong relation between the uses of the interdependent empirical structure audio-visual language in the non-interactive episodes of authority; a decrease of this structure use in the interactive episodes; the creation of education segregation environments within the clasroom and the frequent use of empirical tactile-hearing interdependent language structure in these environments. Moreover, the concept of «special educational need» is discussed and its inadequate use is analyzed. Suggestions are given for its correct use of «special educational need,» its inadequate use, giving suggestions for its correct use.

A equoterapia como auxiliar no processo de inclusão do aluno com deficiência visual: estudo de caso

This study examines the hippotherapy related to school inclusion. Inclusive education, given the diversity of human kind, seeks to understand and meet the educational needs of all students. Visual impairment is defined as a reduction or complete loss of ability to see with the better eye and after the best possible optical correction, and may be perceived by the focus when the individual educational needs of Braille for their learning. Hippotherapy is a therapeutic and educational method that uses the horse in an interdisciplinary approach in health, education and riding, searching for the biopsychosocial development of people with disabilities and/or special needs. The general objectives were: to follow a Hippotherapy program applied to a student with visual disabilities included in regular education from the practice sessions of hippotherapy and the student's school routine, and specific: to verify changes to a student with visual impairment during their participation in an equine therapy program, to check the commitment, involvement and interest in school activities the student practicing hippotherapy inserted into the regular school system. The methodology was a qualitative research, in the form of case study. The instruments of data collection were interviews, video recordings, photographs, school information and the subject of systematic observations of the sessions of hippotherapy. Interviews were conducted at three different times during the course of the program. First we used a strategy for succeeding in increasing the involvement of practicing with the school. Later, another strategy was established, consisting of the effective presence of the researcher in the school to carry out activities on the hippotherapy within the school environment. The analysis of the first interview showed no changes in school interest, however, occurred in the family environment. In analyzing the results of the second interview was seen as a...

Impacto do déficit visual na qualidade de vida em idosos usuários do sistema único de saúde vivendo no sertão de Pernambuco

OBJETIVO: Avaliar o impacto das doenças oculares sobre a qualidade de vida de uma população idosa do sertão de Pernambuco, localizado na região nordeste do Brasil. MÉTODOS: Foram entrevistados 580 indivíduos acima de 59 anos, por meio do questionário de avaliação de qualidade de vida "Visual Functioning Questionnaire" (VFQ). Todos os indivíduos foram submetidos a exame oftalmológico completo. Os resultados das variáveis quantitativas foram expressos por suas médias e desvios- padrão. Os resultados das variáveis qualitativas foram expressos por suas frequências absolutas e relativas. RESULTADOS: A média de idade foi de 70 ± 8,1 anos. Cerca de 86,0% dos entrevistados declararam ser analfabetos ou ter o ensino fundamental incompleto. As principais queixas foram: baixa visual (71,1%) e ardor/prurido (69,0%). A acuidade visual não era normal em 37,4% dos idosos. Por volta de 75,0% dos entrevistados relataram ter saúde regular ou ruim, e 77,0% diziam ter uma visão regular ou ruim. A qualidade de vida foi considerada pior conforme a piora da condição visual do idoso. CONCLUSÃO: O déficit visual representou um impacto negativo sobre a qualidade de vida dos idosos do sertão Pernambucano.

Cataract and cognitive impairment: a review of the literature

Acquired cataract and cognitive impairment are both common age-related problems, and ophthalmologists are increasingly likely to encounter patients who have both. Patients with dementia types who display early visuoperceptual impairment may present first to ophthalmology services. When these patients have coexisting cataract, it may be difficult to distinguish visual complaints due to cataract from those due to dementia. The interaction between visual impairment due to cataract and neurodegenerative disorders affecting the central visual pathways, is not fully understood. Visual impairment due to cataract may stress impaired attentional mechanisms and cataract extraction may improve cognitive performance in some patients with early cognitive impairment; however, the benefits of cataract surgery in established dementia are less clear. In this study, the literature on this subject was reviewed and the implications for practice were considered.

Visual symptoms in Parkinson's disease and Parkinson's disease dementia

Visual symptoms are common in PD and PD dementia and include difficulty reading, double vision, illusions, feelings of presence and passage, and complex visual hallucinations. Despite the established prognostic implications of complex visual hallucinations, the interaction between cognitive decline, visual impairment, and other visual symptoms remains poorly understood. Our aim was to characterize the spectrum of visual symptomatology in PD and examine clinical predictors for their occurrence. Sixty-four subjects with PD, 26 with PD dementia, and 32 age-matched controls were assessed for visual symptoms, cognitive impairment, and ocular pathology. Complex visual hallucinations were common in PD (17%) and PD dementia (89%). Dementia subjects reported illusions (65%) and presence (62%) more frequently than PD or control subjects, but the frequency of passage hallucinations in PD and PD dementia groups was equivalent (48% versus 69%, respectively; P = 0.102). Visual acuity and contrast sensitivity was impaired in parkinsonian subjects, with disease severity and age emerging as the key predictors. Regression analysis identified a variety of factors independently predictive of complex visual hallucinations (e.g., dementia, visual acuity, and depression), illusions (e.g., excessive daytime somnolence and disease severity), and presence (e.g., rapid eye movement sleep behavior disorder and excessive daytime somnolence). Our results demonstrate that different "hallucinatory" experiences in PD do not necessarily share common disease predictors and may, therefore, be driven by different pathophysiological mechanisms. If confirmed, such a finding will have important implications for future studies of visual symptoms and cognitive decline in PD and PD dementia.

Visual function in human ocular toxoplasmosis

AIM: To assess functional impairment in terms of visual acuity reduction and visual field defects in inactive ocular toxoplasmosis. METHODS: 61 patients with known ocular toxoplasmosis in a quiescent state were included in this prospective, cross-sectional study. A complete ophthalmic examination, retinal photodocumentation and standard automated perimetry (Octopus perimeter, program G2) were performed. Visual acuity was classified on the basis of the World Health Organization definition of visual impairment and blindness: normal (> or =20/25), mild (20/25 to 20/60), moderate (20/60 to 20/400) and severe (<20/400). Visual field damage was correspondingly graded as mild (mean defect <4 dB), moderate (mean defect 4-12 dB) or severe (mean defect >12 dB). RESULTS: 8 (13%) patients presented with bilateral ocular toxoplasmosis. Thus, a total of 69 eyes was evaluated. Visual field damage was encountered in 65 (94%) eyes, whereas only 28 (41%) eyes had reduced visual acuity, showing perimetric findings to be more sensitive in detecting chorioretinal damage (p<0.001). Correlation with the clinical localisation of chorioretinal scars was better for visual field (in 70% of the instances) than for visual acuity (33%). Moderate to severe functional impairment was registered in 65.2% for visual field, and in 27.5% for visual acuity. CONCLUSION: In its quiescent stage, ocular toxoplasmosis was associated with permanent visual field defects in >94% of the eyes studied. Hence, standard automated perimetry may better reflect the functional damage encountered by ocular toxoplasmosis than visual acuity.

Distance doubling visual acuity test: a reliable test for nonorganic visual loss

BACKGROUND: To determine the value of the distance doubling visual acuity test in the diagnosis of nonorganic visual loss in a comparative observational case series. METHODS: Twenty-one consecutive patients with nonorganic visual acuity loss and 21 subjects with organic visual loss as controls were included. Best corrected visual acuity was tested at the normal distance of 5 meters using Landolt Cs. The patient was then repositioned and best corrected visual acuity was tested with the previous optotypes at double the distance via a mirror. RESULTS: Nonorganic visual acuity loss was identified in 21 of 21 patients. Sensitivity and specificity of distance-doubling visual acuity test in functional visual loss were found to be 100% (CI; 83%-100%) and 100% (CI; 82%-100%), respectively. CONCLUSION: Distance doubling visual acuity test is widely used to detect nonorganic visual loss. Our results show that this test has a high specificity and sensitivity to detect nonorganic visual impairment.

About the role of visual field defects in pure alexia

Pure alexia is an acquired reading disorder characterized by a disproportionate prolongation of reading time as a function of word length. Although the vast majority of cases reported in the literature show a right-sided visual defect, little is known about the contribution of this low-level visual impairment to their reading difficulties. The present study was aimed at investigating this issue by comparing eye movement patterns during text reading in six patients with pure alexia with those of six patients with hemianopic dyslexia showing similar right-sided visual field defects. We found that the role of the field defect in the reading difficulties of pure alexics was highly deficit-specific. While the amplitude of rightward saccades during text reading seems largely determined by the restricted visual field, other visuo-motor impairments-particularly the pronounced increases in fixation frequency and viewing time as a function of word length-may have little to do with their visual field defect. In addition, subtracting the lesions of the hemianopic dyslexics from those found in pure alexics revealed the largest group differences in posterior parts of the left fusiform gyrus, occipito-temporal sulcus and inferior temporal gyrus. These regions included the coordinate assigned to the centre of the visual word form area in healthy adults, which provides further evidence for a relation between pure alexia and a damaged visual word form area. Finally, we propose a list of three criteria that may improve the differential diagnosis of pure alexia and allow appropriate therapy recommendations.

Dementia presenting with visual complaints

A 78-year-old female developed memory problems after a 2-year history of persistent visual complaints. Ocular pathology did not explain the extent of her perceived visual impairment. Cognitive screening tests found prominent visuo-constructive deficits and a comprehensive dementia assessment revealed the diagnosis of Alzheimer's disease. This case describes visual complaints as the initial symptom of dementia, pre-dating memory impairment by several years. We discuss clinical signs of cerebral visual impairment and suggest a simple screening measure.
