Comparison of Newly Diagnosed Ocular Hypertension and Open-Angle Glaucoma: Ocular Variables, Risk Factors, and Disease Severity

Figure 2

Association of severity of OAG versus risk factors (reduced model). (i) severity of OAG. Advanced disease versus early or moderate disease. (ii) Mean deviation (MD) is a continuous variable, and the others are categorical. MD was estimated in every 1 dB unit of worsening. Categorical variables were estimated as follows: nerve fiber layer defect, localized notching/thinning, disc pallor, peripapillary atrophy, smoking (Yes versus No) and visual field overall (abnormal versus normal). (1) OR = 1 implies a specific risk factor is equally likely in both severity levels, OR > 1 implies more likely in advanced, and OR < 1 implies more likely in early/moderate.
