Design = cross-sectional cohort<br />

Subjects: adult male vinyl chloride pipe<br />

manufacture workers, exposed to Pb stearate<br />

(n = 35), mean age 45 yr (SD 14, range 21–<br />

59); reference group (n = 35) matched <strong>for</strong><br />

age, smoking, and alcohol consumption.<br />

Outcome measures: visual field<br />

Analysis: comparison <strong>of</strong> outcome measures<br />

between Pb workers and reference group<br />

Blood Pb (:g/dL) mean<br />

(SD, range):<br />

Pb: 46 (14, 21–82)<br />

Reference: 23 (4, 21–37)<br />

Urine Pb (:g/L) mean (SD,<br />

range):<br />

Pb: 71 (18, 44–118)<br />

Reference: 30 (5, 21–42)<br />

Visual sensitivity was significantly (p = 0.003) lower in Pb workers<br />

compared to the reference group; however, visual sensitivity index<br />

was not significantly associated with blood or urine Pb. Mesopic<br />

field scotoma prevalence was 10 <strong>of</strong> 35 (28%) in Pb workers and 0%<br />

in the reference group.
