Central versus peripheral vision: evaluation of the residual function resulting from a uniocular macular scotoma.

This paper examines the contribution of the macular region to visual function. Several test targets were used to measure visual performance within 10 deg of the center of the fovea for normal observers and for an observer with a uniocular central 6-deg scotoma. We conclude that the nature of the test target is more important in the measurement of parafoveal than central vision and that the macular region contributes significantly to the visibility of objects as large as 2.5 deg.

Clinician satisfaction with vaccination visits and the role of multiple injections, results from the COVISE Study (Combination Vaccines Impact on Satisfaction and Epidemiology).

Because little is known about clinician satisfaction with infant vaccination visits, we measured satistaction and the effects of the number of injections on satisfaction. Clinicians from 35 pediatric centers self-administered a questionnaire using visual analog scales augmented by a Likert scale. All 95 pediatricians and 137 nonphysician vaccinators responded. In both populations, increased injections predicted decreased overall satisfaction, and decreased satisfaction with obtaining consent, time to prepare/administer, getting upset during administration, and time to update records (each p<0.01). Satisfaction decreased markedly, on each measure, at 4-injection visits, 5-injection visits, or both.
