Glaucomatous Visual Field Defect Severity and the Prevalence of Motor Vehicle Collisions in Japanese: A Hospital/Clinic-Based Cross-Sectional Study

Table 5

Glaucoma severity and MVC prevalence.

Severity grouped by		Mild glaucoma	Moderate glaucoma	Severe glaucoma
MD, worse eye	OR^a	1.07	1.44	2.28
	[95% CI]	[0.55–2.10]	[0.68–3.08]	[1.07–4.88]
	value	0.84	0.34	0.03
MD, better eye	OR^a	1.36	1.82	1.65
	[95% CI]	[0.78–2.37]	[0.65–5.11]	[0.39–6.87]
	value	0.28	0.26	0.49
IVF MD^†	OR^a	1.59	1.01	NA
	[95% CI]	[0.92–2.74]	[0.31–3.28]
	value	0.10	0.99

Multivariable logistic regression analysis adjusted for age, sex, the presence of diabetes mellitus, the proportion of alcohol drinkers, worse eye BCVA, and distance driven per week (controls used as reference).
MVC: motor vehicle collision, BCVA: best corrected visual acuity, MD: mean deviation, IVF: integrated visual field, OR: odds ratio, and CI: confidence interval.
Only 6 subjects with severe glaucoma were categorized by IVF MD; these 6 were analysed with the moderate glaucoma group (logistic regression results did not differ when these two groups were analysed separately).
