Glaucomatous visual field loss associated with less travel from home

Area of Science:

• Ophthalmology
• Public Health
• Gerontology

Background:

• Glaucoma is a leading cause of irreversible blindness worldwide.
• Reduced mobility and social isolation are potential consequences of vision impairment.
• Understanding travel behavior in glaucoma patients is crucial for public health initiatives.

Purpose of the Study:

• To investigate the association between glaucoma and travel behavior.
• To quantify differences in daily excursions and time spent away from home between glaucoma patients and controls.

Main Methods:

• A cohort of 59 glaucoma suspects and 80 glaucoma patients were monitored using cellular tracking devices for one week.
• Location data were analyzed to determine the number of daily excursions and time spent away from home.
• Statistical models were used to assess the relationship between glaucoma status, visual field mean deviation, and travel behavior.

Main Results:

• Glaucoma patients exhibited fewer daily excursions and a higher likelihood of not leaving home compared to controls.
• Each 5-decibel decrement in better-eye visual field mean deviation was associated with reduced daily excursions and increased odds of staying home.
• While total time spent away from home did not differ significantly between groups, greater visual field loss correlated with decreased time away.

Conclusions:

• Glaucoma patients, especially those with significant visual field loss, are more homebound than individuals with normal vision.
• This reduced mobility may negatively impact physical fitness and overall health.
• Interventions such as orientation and mobility training should be considered to promote safe travel and encourage activity outside the home for individuals with glaucoma.
