Wider Retinal Artery Trajectories in Eyes with Macular Hole Than in Fellow Eyes of XXXX with @entity937 .

@entity1 @entity735 @entity937 @entity989
PURPOSE: To determine whether the width of the @entity989 ( @entity989 ) trajectory was associated with the presence of a @entity937 ( @entity937 ). METHODS: A retrospective cross sectional case-control study was performed. The fundus photographs were rotated 90 degrees, and the coordinates of the best fit curve of the @entity989 trajectory were determined automatically based on these plots using the ImageJ program. The converted coordinates were fit to a second degree polynomial (ax2/100 + bx + c) equation. The width and steepness of the @entity989 trajectory, "a", of the eyes with a @entity937 eye were compared to that of the fellow eyes. RESULTS: One hundred and ten eyes of 55 consecutive @entity1 (30 @entity1 ) with a unilateral @entity937 and healthy fellow eyes were analyzed. The mean age was 64.9 years (range 47-81 years). The constant 'a' was significantly smaller in eyes with a @entity937 than that of the fellow eyes (0.379    0.094 vs 0.416    0.121, P = 0.001, paired t test), indicating that the @entity989 trajectory was wider in the @entity735 . There was a significant correlation between the axial length and 'a' of the @entity989 trajectory in the @entity937 eyes (R = 0.273, P = 0.044) and in the fellow eyes (R = 0.356, P = 0.008; Spearman's rank correlation coefficient). CONCLUSIONS: Because eyes with a @entity937 have a significantly wider and flatter @entity989 trajectory, there may be greater traction on the fovea which is located between the @entity989 arches. The causative role of this finding is still unclear.
