Decreased visual field reduces mobility outside the home
According to a study by the Wilmer Eye Institute, people with severe visual field damage do not tend to experience restrictions on activities performed at home, but their level of movement has decreased in other places.
“Physical activity takes place in a variety of places and settings, and many interventions to improve physical activity focus on increasing activity in a specific location, such as at home or in a activity or fitness center ‘ Jian-Yu E, MD, SeD, MPH, and colleagues wrote.
E and his colleagues used GPS tracking to determine the distance traveled by 229 study participants from their homes and the intensity of their physical activity levels for 7 consecutive days. The average age of the participants was 71 years and 51% were men.
The researchers calculated the visual field damage (VF) of the individuals, which was defined as “the average sensitivity within the integrated VF (IVF)”. Half of the participants had normal or mild VF damage, 40% had moderate VF damage, and 10% had severe VF damage.
They used multivariate negative binomial regression to test for the correlation between low activity levels and severe susceptibility of IVF. The investigators’ goal was to find out where glaucoma patients engage in physical activity and which places are the safest to do so.
The results showed that despite the differences in VF levels, patients generally spent the same time away from home or on excursions per week.
Researchers found moderate and vigorous physical activity (MVPA) to be lowest in the severe VF groups. People with severe VF lesions had 48% fewer minutes of MVPA per day (RR = 0.52; 95% CI: 0.27-1) and 53% fewer minutes of MVPA per excursion (RR = 0.47; 95% CI 0.23 0.96) compared to normal and mild VF damage.
According to study data, participants with severe VF lesions spent more time at home than patients with normal or mild VF lesions, but all groups had similar MVPA levels and step count. the House. Investigators wrote that this indicates a “specific lack of confidence to perform activities outside the home in patients with more severe glaucoma.” In addition, these people may be at greater risk of “worse mobility, possibly due to social isolation, depression and difficulty accessing health services outside the home”.
More research is needed to determine which features would improve home security and their effectiveness, according to E and colleagues.
Some limitations of this study include a lack of generalizability because the participants came from a single center and were mostly well educated and aware. In addition, the study did not show any temporal relationships between damage and VF activity, suggesting the need for longitudinal analysis.
“These results underscore the importance of maintaining a safe home environment (where activity is less restricted) and of increasing confidence in performing an activity upon leaving home,” concluded E and colleagues.
