“…This result is consistent with previous research showing that during near work tasks an increased use of optical enlargement in visual enhancing devices may adversely result in restricted postures [22, 26, 27, 35] that subsequently can lead to increased musculoskeletal complaints as well as balance complaints [15, 17]. …”

Purpose. To investigate whether patients with age-related macular degeneration (AMD) run a potentially higher risk of developing visual, musculoskeletal, and balance complaints than age-matched controls with normal vision. Methods. Visual assessments, self-rated visual function, self-rated visual, musculoskeletal, and balance complaints, and perceived general health were obtained in 37 AMD patients and 18 controls, at baseline and after an average of 3.8 years later. Results. At follow-up both groups reported decreased visual acuity (VA) and visual function, but only AMD patients reported significantly increased visual, musculoskeletal, and balance complaints. Decreased VA, need for larger font size when reading, need for larger magnification, and decreased self-rated visual function were identified as risk markers for increased complaints in AMD patients. These complaints were also identified as risk markers for decreased health. For controls, decreased VA and self-reported visual function were associated with increased visual and balance complaints. Conclusions. Visual deterioration was a risk marker for increased visual, musculoskeletal, balance, and health complaints in AMD patients. Specifically, magnifying visual aids, such as CCTV, were a risk marker for increased complaints in AMD patients. This calls for early and coordinated actions to treat and prevent visual, musculoskeletal, balance, and health complaints in AMD patients.

“…31 However, the motor demands of operating an optical or electronic magnifier can sometimes reduce reading speed. 32 The combined effects on reading performance could be assessed by measuring the ACC with and without the magnifier.…”

“…96 Page navigation strategies with optical magnifiers were measured by Bowers and colleagues. 97 They found that vision measures were more strongly associated with forward navigation time than retrace navigation, reflecting the greater degree of visual and cognitive processing that occurs when reading along a line than the minimal processing that occurs during retrace. In general, navigation errors were not well predicted by any of the vision or magnifier measures.…”

“…In addition, new magnifier users may have difficulty manipulating the magnifier across the page to read (forward movement) and back across the page to find the start of the next line (retrace movement), which is termed page navigation 96 . Page navigation strategies with optical magnifiers were measured by Bowers and colleagues 97 . They found that vision measures were more strongly associated with forward navigation time than retrace navigation, reflecting the greater degree of visual and cognitive processing that occurs when reading along a line than the minimal processing that occurs during retrace.…”

The past 40 years has seen a great expansion in low-vision research, which has changed low-vision teaching and our clinical management of people with low vision. Australian optometrists have contributed significantly to this research and the development of multidisciplinary low-vision services. This paper reviews the research that has shaped our clinical assessment and patient management for reading by adults with low vision. The major improvements in clinical assessment of low vision for reading were brought about by the improvements in distance and near visual acuity measurements during the 1970s and research during the 1980s and 1990s showing the factors affecting the reading rate. These changes, together with a different method for representing the magnification provided by optical and electronic systems, allows a scientific, logical and practical method for prescribing magnification. An illustration of the step-by-step approach for prescribing magnification for low-vision reading that is easy to apply in any clinical practice is included.
