Abstract
Purpose: The purpose of this study was to investigate the hypothesis that muscle-related factors influence glaucoma risk, we examined the association of grip strength (GS), thigh muscle volume (TMV), and walking pace (WP) with glaucoma and its related traits.</p>
Methods: We included UK Biobank participants with data on IOP (N = 114,284), optical coherence tomography (OCT) macular inner retinal layer thickness measures (N = 44,141) and glaucoma status (N = 105,556; 2006-2010). Linear regression was used to evaluate multivariable-adjusted associations of GS, TMV, and WP with IOP and macular inner retinal OCT parameters, and logistic regression was used to evaluate associations with glaucoma status. We additionally examined gene-GS interactions with each outcome using a polygenic risk score (PRS) that combined the effects of 2673 genetic variants associated with glaucoma.</p>
Results: After adjustment for key anthropometric, lifestyle, and medical covariables, we found each additional standard deviation (SD) increase in GS (8.6 kg in men and 6.1 kg in women) was associated with thicker macular retinal nerve fiber layer (mRNFL) by 0.08 µm (P = 0.013) and 0.07 µm (P = 0.010) in men and women, respectively; thicker macular ganglion cell-inner plexiform layer (mGCIPL) by 0.12 µm (P = 0.003) and 0.17 µm (P < 0.001); higher IOP by 0.15 millimeters of mercury (mm Hg; P < 0.001) and 0.16 mm Hg (P < 0.001) and lower odds of glaucoma (odds ratio [OR] = 0.83, P < 0.001) in men only. The association with glaucoma was replicated in the independent EPIC-Norfolk cohort. Faster WP and greater TMV were also associated with lower odds of glaucoma in men only (P = 0.004 and P = 0.017, respectively). Stronger GS-IOP associations were observed in participants with a higher level of genetic risk for glaucoma (Pinteraction < 0.001).</p>
Conclusions: In this cross-sectional and gene-environment interaction study, factors relating to muscle strength, mass, and function were consistently associated with higher IOP, thicker inner retinal OCT measures in both sexes, and lower odds of glaucoma in men.</p>
