“…Reading speed is defined as a measure of the speed at which individual can read a text (McAllister & Kammer, 2014). Maximum reading speed is the top rate at which a text can be read while still drawing semantic understanding from the text.…”

“…Of these, researchers have reported that the most frequent reason individuals with sensory impairments seek low vision rehabilitation services is due to difficulty reading (Elliott et al, 1997;Rubin, 2013). Given this, reading is often targeted in low vision rehabilitation through behavioural training (e.g., eccentric viewing training) or through the use of assistive technology devices that magnify text (e.g., Closed Circuit Televisions; Massof, 1995;McAllister & Kammer, 2014;Southall & Wittich, 2012). Thus, reading speed is one of the most frequently used measures used by researchers and clinicians to assess improvements in clients reading speed pre and post receiving low vision rehabilitation services (Binns et al, 2012;McAllister & Kammer, 2014;Nguyen, Weismann, & Trauzettel-Klosinski, 2009;Rubin, 2013;Sass, Legge, & Lee, 2006).…”

Validation of the International Reading Speed Texts in a Canadian Sample Elliott MorriceThe English language IReST is a measure of continuous reading, developed and Validation of the International Reading Speed Texts in a Canadian SampleThe International Reading Speed Texts (IReST) have been developed as a standardized measure used to assess continuous reading in normally sighted individuals, and those with visual impairments (Trauzettel-Klosinski & Dietz, 2012). Within the IReST, each text contains a measure of mean reading rate (in words per minute) and variance (standard deviation), allowing for comparisons between an individual and the published reading rates. This assessment was developed in Europe, and has been translated and validated in 17 different languages, including English. The English language IReST texts were developed and normalized using a sample in the United Kingdom (UK), and as such, the texts use terms and phrases that are commonly used in the UK. Although the IReST were developed and normalized in the UK, it is sold internationally, and is used throughout the United States and Canada as a measure to assess reading speed. This raises the problem that because the normative values developed for the IReST are based on a UK English speaking sample, then these normative values may not be valid in a North American (NA) English speaking population. Therefore, the aim of the current thesis is to validate the IReST in an English-speaking NA sample.

“…According to the definition by the World Health Organisation (WHO), a person with low vision is one who has impairment of visual functioning even after treatment and/or standard refractive correction, and has a visual acuity of less than 6/18 (USA: 20/60) to light perception, or a visual field less than 10° from the point of fixation, but who uses, or is potentially able to use, vision for the planning and/or execution of a task for which vision is essential ( McAllister & Kammer, 2014 ). This definition guided the planning and implementation of the reported study from the start.…”

Objective: Visual impairment restricts performance in activities of daily living. The aim of this study was to classify types of visual loss associated with function in older adults based on clinical data and World Health Organization (WHO) acuity and visual field criteria. Methods: Seven hundred retrospective medical records of older adults seen at the outpatient ophthalmology clinics of a Singapore hospital were reviewed. Extracted data was mapped to the WHO low vision criteria. A flow chart was developed to classify the main types of visual loss aligned with function. Results: The flow chart developed describes four major types of visual loss: (1) full visual field with decreased visual acuity, (2) any visual field loss with greater than ten degrees of available field, (3) peripheral field loss with less than 10° of available field, and (4) any visual field loss due to a cortical event. Within each major type, sub-categories were identified reflecting the complexity of the visual impact of the eye conditions. Conclusion: The flow chart can be applied to outpatient records to identify older adults with different types of visual loss to inform targeted rehabilitation linked with function.
