What this trial studies
We have recently developed and optimized a vaginal Optical Coherence tomography/angiography endoscopy imaging system. This technology is able to obtain a comprehensive image of the vaginal epithelium, blood vessels, and lamina propria. The primary focus of this study is establishing the Optical Coherence Tomography system's capability of capturing vaginal changes that occur before and after menopause, as well as before and after treatment with fractional-CO2 laser therapy. There are two aims of this study.
Conditions in scope
- Genitourinary Syndrome of Menopause
Interventions
- CO2 laser (Device) — Fractional CO2 vaginal laser for genitourinary syndrome of menopause
- OCT (Device) — Optical coherence tomography endoscope
