PURPOSE: To compare the difference in the progression of posterior vitreous detachment (PVD) between men and women in relation to age. DESIGN: Observational cross-sectional study. PARTICIPANTS: One hundred eyes of 100 male patients and 100 eyes of 100 female patients in 4 age groups: 40 to 49 years of age, 50 to 59 years of age, 60 to 69 years of age, and 70 years of age or older. METHODS: Using swept-source (SS) OCT, PVD was classified into 5 stages: 0, no PVD; 1, paramacular PVD; 2, perifoveal PVD; 3, vitreofoveal separation; and 4, complete PVD. The PVD stage distribution was compared between men and women in the 4 age groups and among the age groups. MAIN OUTCOME MEASURES: Stage of PVD determined using SS OCT. RESULTS: In both male and female eyes, the stage of PVD progressed significantly in association with the age group (P < 0.0001). The distribution of the PVD stage did not differ significantly between men and women in the 40- to 49- and the 50- to 59-year age groups. The distribution of the PVD stage was significantly more progressed in women than in men, however, in those 60 to 69 years of age and those 70 years of age and older (P ≤ 0.0292). At 40 to 49 years of age, no PVD (stage 0) and paramacular PVD (stage 1) were detected in 92 (92.0%) female eyes and 93 (93.0%) male eyes. At 70 years of age or older, vitreofoveal separation (stage 3) and complete PVD (stage 4) were detected in 93 (93.0%) female eyes and 78 (78.0%) male eyes. CONCLUSIONS: Posterior vitreous detachment significantly progresses with age in both genders, specifically between 40 years of age and 70 years of age or older. Posterior vitreous detachment progression occurs significantly faster in female eyes than in male eyes at 60 years of age or older, suggesting that the macular pathologic features associated with PVD occur at a younger age in women.
