"Modified Schirmer Test" as an Objective Measurement for Vaginal Dryness: A Prospective Cohort Study

Area of Science:

• Gynecology
• Medical Devices
• Diagnostic Tools

Background:

• Current methods for assessing vaginal moisture lack objectivity.
• Vaginal dryness significantly impacts women's quality of life, particularly during menopause.

Purpose of the Study:

• To validate a novel, objective method for quantifying vaginal fluid using a modified Schirmer test.
• To assess the correlation between the modified Schirmer test and established indicators of vaginal health.

Main Methods:

• A calibrated filter paper strip, termed the "modified Schirmer test," was employed to measure vaginal fluid.
• Measurements were compared between symptomatic women with genitourinary syndrome of menopause and asymptomatic controls.

Main Results:

• The modified Schirmer test showed significantly lower measurements in women with vaginal dryness (3.3 mm) compared to controls (21.7 mm; p < 0.001).
• Strong correlations were observed between the modified Schirmer test and vaginal pH (-0.714), Vaginal Health Index (VHI) (0.775), and Visual Analogue Score (VAS) for dryness (-0.821).

Conclusions:

• The modified Schirmer test provides a reliable and objective assessment of vaginal fluid levels.
• This test holds potential for evaluating the efficacy of non-hormonal treatments for vaginal dryness.
