Purpose: To determine the prevalence and factors influencing vitreomacular adhesion (VMA) or vitreomacular traction (VMT) in subjects without maculopathy older than age 40 years. Methods: In a prospective cross-sectional study, 1,950 eyes in 1,090 participants aged 40 to 89 years representing various ethnic groups from 14 centers in the United States underwent a comprehensive eye examination, including spectral domain optical coherence tomography. A team of independent, masked readers classified the presence or absence of VMA/VMT on spectral domain optical coherence tomography based on the International Vitreomacular Traction Study Group rubric. Results: Across all eyes, the prevalence of VMA or VMT was 39% or 1%, respectively. For every 1-year increase in age, there was a statistically significant 7% decreased odds of having VMA or VMT (95% confidence interval [CI]: 0.89–0.96; P < 0.001), whereas African Americans had 55% significantly reduced odds of having VMA or VMT when than whites (95% CI: 0.23–0.90; P = 0.025). Vitreomacular adhesion >1,500 &mgr;m was significantly more likely than VMA <1,500 &mgr;m in younger adults (95% CI: 0.70–0.86; P < 0.001), hyperopes versus emmetropes (95% CI: 1.49–35.9; P = 0.01), primary eye care versus tertiary practices (95% CI: 0.03–0.92; P = 0.04), and patients without hyperlipidemia (95% CI: 0.04–0.83; P = 0.03). Conclusion: Vitreomacular adhesion is highly prevalent among middle-aged adults. Diagnostic screening with spectral domain optical coherence tomography may help to accurately detect VMA or VMT, prompting routine monitoring and timely therapeutic intervention.
