PURPOSE. To assess the spatial relationship between the locations of the parapapillary gamma zone and the fovea. METHODS. In a non-glaucomatous subgroup of the population-based Beijing Eye Study population, we measured the mean angle between the optic disc-fovea line and the horizontal (disc-fovea angle), the vertical distance of the fovea from the horizontal through the optic disc center (fovea vertical distance), and the location and width of the widest part of parapapillary gamma zone. RESULTS. The study included 203 individuals (203 eyes; mean axial length, 24.4 +/- 1.5 mm; range, 22.03-28.87 mm). The widest gamma zone part was located most often temporal horizontally (51.7%), then inferiorly (43.8%), superiorly (2.5%), and nasally (2.0%). The disc-fovea angle (mean, 7.50 degrees +/- 4.00 degrees; range, -6.30 degrees to -23.25 degrees) was significantly higher (P = 0.003; i.e., fovea located more inferiorly) in eyes with the widest gamma zone inferiorly (8.46 degrees +/- 4.37 degrees) than in eyes with the widest gamma zone temporally (6.71 degrees +/- 3.46 degrees) and in eyes with the widest gamma zone temporally, superiorly, or nasally combined (6.75 degrees +/- 3.53 degrees; P = 0.003). The fovea vertical distance (mean, 0.65 +/- 0.33 mm; range, -0.20 to 1.67 mm) was longer (P = 0.001; i.e., fovea located more inferiorly) in eyes with the widest gamma zone inferiorly (0.73 +/- 0.33 mm) than in eyes with the widest gamma zone temporally (0.58 +/- 0.30 mm) and in eyes with a temporal, superior, or nasal gamma zone combined (0.58 +/- 0.31 mm; P = 0.001). The fovea vertical distance increased (multivariate analysis) with the widest gamma zone location inferiorly (beta = 0.25; P = 0.001) and wider width of the gamma zone (beta = 0.19; P = 0.01). CONCLUSIONS. An inferior fovea location is associated with a wider inferior gamma zone and vice versa, supporting the notion of an inferior shifting of Bruch's membrane as the cause for an inferior gamma zone.
