The association between primary open-angle glaucoma and motor vehicle collisions

Area of Science:

• Ophthalmology
• Public Health
• Road Safety

Background:

• Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
• Visual field defects in POAG can impair driving ability.
• The association between POAG and motor vehicle collisions (MVCs) requires further investigation.

Purpose of the Study:

• To compare the prevalence of MVCs in individuals with and without POAG.
• To assess the relationship between POAG severity and MVC frequency.

Main Methods:

• 265 participants (121 with POAG, 144 controls) completed questionnaires on MVC history and driving habits.
• POAG patients were categorized by disease severity (mild, moderate, severe).
• Logistic regression analysis controlled for confounding factors like age and visual acuity.

Main Results:

• A significant association was found between POAG severity and MVC frequency (P = 0.007).
• The severe POAG group reported a substantially higher MVC frequency than controls (P < 0.010).
• Mild and moderate POAG groups showed no significant increase in MVCs compared to controls.

Conclusions:

• Advanced POAG, characterized by significant visual field defects, is a potential risk factor for MVCs.
• Driving safety may be compromised in individuals with severe POAG.
• Ophthalmologists should consider driving risks in patients with advanced glaucoma.
