Morphology of the normal visual field in a population-based random sample: principal components analysis.

I applied principal components analysis to Humphrey central 24-2 threshold values from both eyes of 304 clinically normal persons selected by simple random sample from Barbados, WI. The first component, accounting for 62 per cent of the variation, is equivalent to the average threshold value within persons. The first eigenvector, when represented by grey scale maps depicting a pair of eyes, reveals that, as average threshold increases, the visual field rises and flattens, like an umbrella that, initially closed, is simultaneously opened and thrust upwards. I verify three numerical predictions based upon this umbrella description. Much less important sources of variation involve disparity between fellow eyes, and hemimeridional and other symmetric differences within eyes. I discuss briefly possible physiologic explanatory mechanisms.

Comparison of condom breakage during human use with performance in laboratory testing.

This paper combines results from a study of the determinants of condom quality and use conducted by The Population Council in two countries in the Caribbean with results from a condom breakage study conducted by Family Health International (FHI) in the United States. The studies, conducted two years apart, compared the breakage rates of condoms from the same lot during human use to their performance in laboratory test results. Breakage rates of 12.9% for Barbados, 10.1% for St. Lucia and 6.7% for the United States compared to passing ASTM laboratory tests suggest that existing laboratory tests as used with the current pass/fail standards are either not sufficiently sensitive or not well-defined to reliably predict condom performance during human use. The study also suggests that user behaviors and practices may be a factor in condom breakage. If the condom is to be an effective method against unplanned pregnancy and STD/HIV infection, and if consumer confidence is to be retained, condom breakage during sexual intercourse must be reduced.
