Functional Vision Assessment

Introduction: Within the field of visual impairment, there is no set of standards that guide teachers of students with visual impairments as they conduct, report, and share functional vision assessment (FVA) results with other educational team members, and university instructors vary in how they teach the assessment process to preservice teachers. Methods: In parallel, a group of teachers of students with visual impairments and a group of university instructors completed three rounds of a Delphi study. After providing background information in Round 1, they rated 84 statements about the FVA process. The level for consensus was set at 80%. Results: Of the 84 statements, consensus was reached for 45 statements regarding the level of importance by both groups. Participants rated 11 of 22 visual skills (e.g., near acuity, distance acuity) as extremely important to include in the FVA process. Discussion: There continues to be a need to build consensus on when FVAs should be conducted, what visual skills should be included when conducting them, what should be included in reports, and with whom assessment information should be shared. The importance of conducting such assessments for all students, including students under the age of 5 years and those with additional disabilities, needs to be recognized by the field of visual impairment. Implications for practitioners: University personnel need to work together to develop consistent curricula that focuses on the FVA process. Future studies that examine the FVA practices of individual teachers are necessary.

This article discusses genetic syndromes that are etiologies of severe disabilities that include the characteristic of visual impairment. Information provided about refractive errors, field loss, cortical visual impairment, and ocular issues is intended to support the practitioner outside the field of visual impairment to collaborate with the teacher of students with visual impairments (TVI). This article provides an overview of the responsibilities of the TVI who can advise others about appropriate enlargement of materials, positioning for optimal use of functional vision, and adaptations to lessons such as the individualized daily schedule. Additionally, the TVI is familiar with instructional strategies to support the use of functional vision and to develop tactile skills. This article concludes with a discussion of the importance of interprofessional collaboration.

Abstract Introduction: the identification of Zika virus (ZikV) in the amniotic fluid, in the placenta and in newborns' brains suggests a neurotropism of this agent in the brain development, resulting in neuro-psycho-motor alterations. Thus, this present study reports the assessment of children diagnosed by a congenital infection, presumably by ZikV, followed-up at the Rehabilitation Center Prof. Ruy Neves Baptist at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP). Description: as proposed by the Ministry of Health, the following instruments were used to evaluate the neuro-motor functions of four children with microcephaly aged between three and four months: The Test of Infant Motor Performance (TIMP); the functional vision assessment; the manual function scale development; and the clinical evaluation protocol on pediatric dysphagia (PAD-PED). Discussion: the children evaluated presented atypical motor performance, muscle tone and spontaneous motricity which encompass the symmetry and the motion range of the upper and lower limbs proven to be altered. The functional vision showed alterations which can cause limitations in the performance of functional activities and the learning process. Regarding to the speech articulator's functions observed that the maturation and coordination of sucking, swallowing and breathing did not yet encounter the appropriate age maturity level.

The analyses presented in the article aim to investigate the specific nature of visual problems in a young child whose visual disability results from a brain tumor. The article presents a case study on difficulties in using vision and visual perception development in an almost 4-year-old boy with a brain tumor. It refers to knowledge concerning visual problems in children with brain tumors that is available in source materials and presents a detailed description of difficulties in visual reception and perception in a boy whose visual problems result from cancer. This description was made based on the results of a functional vision assessment. Decreased visual acuity, reduced visual fields, abnormalities in the development of oculomotor functions, lack of spatial vision, and difficulties in visual perception were found in the boy. Both the analysis of medical literature presented in the paper and the results of the boy's functional vision assessment suggest possible development of visual functioning disorders secondary to a brain tumor, such as decreased visual acuity and reduced visual fields, which determine visual abilities and have an adverse impact on the development of visual perception in early life. Based on the analysis of an individual situation, the description of difficulties in visual functioning suggests there is a risk of similar impairments in children with brain tumors.

ObjectivesVisual impairment following stroke is common with a reported incidence of visual impairment in 60% of stroke survivors. Screening for visual impairment is neither routine nor standardised. This results in a health inequality where some stroke survivors receive comprehensive vision assessment to identify any existent visual problems while others receive no vision assessment leaving them with unmet needs from undiagnosed visual problems. The aim of this study was to define two core outcome sets (COS), one for vision screening and one for full visual assessment of stroke survivors.DesignA list of potentially relevant visual assessments was created from a review of the literature. The consensus process consisted of an online 3-round Delphi survey followed by a consensus meeting of the key stakeholders.ParticipantsStakeholders included orthoptists, occupational therapists, ophthalmologists, stroke survivors and COS users such as researchers, journal editors and guideline developers.SettingUniversity.Outcome measuresCOS.ResultsFollowing the consensus process we recommend the following nine assessments for vision screening: case history, clinical observations of visual signs, visual acuity, eye alignment position, eye movement assessment, visual field assessment, visual neglect assessment, functional vision assessment and reading assessment. We recommend the following 11 assessments for full vision assessment: case history, observations, visual acuity, eye alignment position, eye movement assessment, binocular vision assessment, eye position measurement, visual field assessment, visual neglect assessment, functional vision assessment, reading assessment and quality of life questionnaires.ConclusionsCOS are defined for vision screening and full vision assessment for stroke survivors. There is potential for their use in reducing heterogeneity in routine clinical practice and for improving standardisation and accuracy of vision assessment. Future research is required to evaluate the use of these COS and for further exploration of core outcome measures.
