The pattern of neuroretinal rim loss and increase in the area of parapapillary atrophy in glaucoma depend on the localization of the central retinal vessel trunk in the lamina cribrosa. The purpose of the present study was to determine whether, in a similar way, the pattern of rim loss and progression of parapapillary atrophy are influenced by the presence and position of cilioretinal arteries.
Color stereo optic disc photographs (15 degrees) for morphometric evaluation of the optic nerve head were used to compare the appearance of the optic disc in 41 patients exhibiting unilateral or bilateral cilioretinal arteries in the temporal horizontal disc region with the optic disc morphology of 127 patients without cilioretinal arteries. The areas of the neuroretinal rim and alpha and beta zones of parapapillary atrophy were measured in the total disc and in four disc sectors.
Eyes with and eyes without cilioretinal arteries did not differ significantly in the areas of neuroretinal rim and alpha and beta zones of parapapillary atrophy, when measured in the whole optic disc and in the four disc sectors separately; in ratios of the temporal horizontal area to total area of rim and parapapillary atrophy; and in the ratio of temporal horizontal rim area-to-nasal rim area, neither in an interindividual comparison nor in an intraindividual intereye comparison.
In contrast to the position of the central retinal vessel trunk, presence and position of cilioretinal arteries do not markedly influence the pattern of neuroretinal rim loss and progression of parapapillary atrophy in glaucoma.
青光眼患者神经视网膜边缘萎缩的模式以及视乳头旁萎缩区域的增加取决于视网膜中央血管主干在筛板中的位置。本研究的目的是确定视网膜睫状动脉的存在和位置是否以类似方式影响边缘萎缩模式和视乳头旁萎缩的进展。
使用用于视神经乳头形态学评估的彩色立体视盘照片（15度），比较41例在颞侧水平视盘区域有单侧或双侧视网膜睫状动脉患者的视盘外观与127例无视网膜睫状动脉患者的视盘形态。在整个视盘和四个视盘扇区中测量神经视网膜边缘以及视乳头旁萎缩的α和β区的面积。
分别在整个视盘和四个视盘扇区中测量时，有视网膜睫状动脉的眼睛和无视网膜睫状动脉的眼睛在神经视网膜边缘以及视乳头旁萎缩的α和β区的面积、颞侧水平面积与边缘和视乳头旁萎缩总面积的比率以及颞侧水平边缘面积与鼻侧边缘面积的比率方面，无论是个体间比较还是个体内双眼比较，均无显著差异。
与视网膜中央血管主干的位置不同，视网膜睫状动脉的存在和位置不会明显影响青光眼患者神经视网膜边缘萎缩的模式和视乳头旁萎缩的进展。
