10 women were randomized to use placebo vaginal gel twice daily for 5.5 days. The vagina and cervix were examined using standard colposcopy and a new method, OCT, to determine the ability of OCT to detect vaginal/cervical findings not detected by colposcopy.
20 women were randomized to use the over-the-counter spermicide N-9 as a vaginal gel twice daily for 5.5 days. The vagina and cervix were examined using standard colposcopy and a new method, OCT, to determine the ability of OCT to detect vaginal/cervical findings not detected by colposcopy.

Vincent KL, Stanberry LR, Moench TR, Breitkopf CR, Loza ML, Wei J, Grady J, Paull J, Motamedi M, Rosenthal SL. Optical coherence tomography compared with colposcopy for assessment of vaginal epithelial damage: a randomized controlled trial. Obstet Gynecol. 2011 Dec;118(6):1354-61.
Results: Colposcopy findings, optical coherence tomography scores, and epithelial thicknesses were similar between treatment groups at baseline. After treatment, there were significant differences between the nonoxynol-9 (1.37) and control group (1.15) optical coherence tomography scores (P<.001), indicating epithelial injury, and there was epithelial thinning in the nonoxynol-9 group (237 micrometers) compared with the control group (292 micrometers; P=.008). There were no significant posttreatment colposcopic differences in epithelial disruption between treatment groups, with only increased erythema noted after nonoxynol-9 use (P=.02).
CONCLUSION: Optical coherence tomography detected epithelial disruption and thinning not identified by colposcopy. Vaginal epithelial thickness, a measure previously available only through biopsy, decreased after nonoxynol-9 use, a finding that may contribute to increased susceptibility to human immunodeficiency virus after frequent use. Optical coherence tomography shows promise for the noninvasive clinical assessment of vaginal epithelial damage.
