The effects of low vision and vision loss are as diverse and profound as the people it impacts. As we investigate how vision loss plays into both cognitive processing and physical skills for our patients, it is the universal need to maximize independence and quality of life that we, as practitioners, strive to promote. To do this effectively, we must consider a comprehensive approach to evaluation and assessing what our patients engage in throughout the day.
For individuals who suffer from low-vision and age-related macular degeneration (AMD), we are mindful of the vast functional decline they may be facing such as:
- Visual cognitive processing skills
- Ambulation and functional mobility
- Orientation
- Falls and balance
- Community mobility including driving
- Overall safety in environment due to lack of ability to recognize visual cues
When you are treating a patient with potential vision loss, remember to think broader on how these skills impact all of the other
Maximizing treatment, which will increase adaptive options as well as early training in the process, has been shown to facilitate longer periods of independence throughout the disease process. Moreover, Liu and Chang (2019) recognize the need for low vision interventions to decrease commonly linked, and secondary effects of these conditions. In their study, they highlight low vision and links to depression, anxiety, decreased independence and mobility both in home and in the community.
