A comparison of techniques to assess cervicovaginal irritation and evaluation of the variability between two observers.

Background: Colposcopy is used to evaluate effects of new vaginal products on cervicovaginal epithelium as part of the US Food and Drug Administration-mandated product approval process, yet few aspects of its use have been investigated.

Objectives: To determine the effect of the colposcopic examination itself on the number and type of findings seen, to compare colposcopy with the AviScope hand-held device and the naked eye and to compare the findings reported by two examiners during a single visit.

Study Design: Fourteen healthy women volunteered for five paired examinations in random order: (1) naked eye inspection plus colposcopy done twice by a single examiner; (2) naked eye inspection plus AviScope examination, then naked eye inspection plus colposcopy by a single examiner; (3) Examination 2 repeated with the order of device reversed; (4) naked eye inspection plus colposcopy done by two examiners; (5) Examination 4 repeated with the order of examiner reversed.
