目的观察高度近视患者后极部各个象限视网膜动静脉曲折度及分叉角的变异.方法对比分析高度近视患者32例52只眼以及正常人22例30只眼后极部不同象限视网膜血管曲折度及分叉角大小,并比较高度近视后极部视网膜血管与正常眼的差异.多变量方差分析对结果进行分析,P<0.05为差异有统计学意义.结果高度近视眼由视盘发出平行走向黄斑的血管,动脉曲折度分别为(1.29±1.10)×10-4、(5.39±1.93)×10-5;正常眼分别为(4.15±2.38)×10-4、(9.75±4.99)×10-5,两组差异均有统计学意义(t=1.99,2.00;P<0.05).高度近视眼视网膜动脉鼻上鼻下分叉角分别为(66.17±14.04)°、(61.20±11.02)°,正常眼分别为(77.66±14.12)°、(85.86±16.45)°,两组差异均有统计学意义(F=0.77,0.83;P<0.05).高度近视眼视网膜静脉颞上颞下分叉角分别为(92.39±20.36)°、(83.56± 23.50)°,正常眼分别为(79.45±15.94)°、(70.59±17.27)°,两组比较差异均有统计学意义(F=2.34,1.83;P<0.05).结论高度近视眼视网膜动脉及从视盘发出平行走向黄斑的血管曲折度变小,与动脉相应静脉曲折度变化不明显;高度近视眼底血管动脉鼻上鼻下分叉角较正常眼较小,高度近视眼底静脉颞上颞下分叉角较正常眼增大.

Objective To observe the changes of tortuosity and bifurcation angle of retinal arteries and veins in each quadrant of the posterior pole in eyes with high myopia. Methods The tortuosity and bifurcation angle of retinal vessels in each quadrant of the posterior pole in 32 patients (52 eyes) with high myopia and 22 healthy people (30 eyes) were observed and compared. The outcomes were analyzed by multivariate analysis of variance. Results The tortuosity of macular vessels and the artery from optic disc in eyes with high myopia was (1.29±1.10)×10-4 and (5.39±1.93)×10-5 respectively, and in the normal eyes was (4.15±2.38)×10-4 and (9.75±4.99)×10-5 respectively; there was significant difference between the two groups (t=1.99, 2.00; P<0.05). The bifurcation angle of superior nasal and inferior nasal retinal arteries in eyes with high myopia was(66.17±14.04)° and (61.20±11.02)° respectively, and in the normal eyes was (77.66±14.12)° and (85.86±16.45)° respectively; there was significant difference between the two groups (F=0.77, 0.83; P<0.05). The bifurcation angle of superior temporal and inferior temporal retinal veins in eyes with high myopia was (92.39±20. 36)° and (83.56±23.50)° respectively, and in the normal eyes was (79.45±15.94)° and (70.59±17.27)°; there was significant difference between the two groups (F=2.34, 1.83; P<0.05). Conclusions The vessel tortuosity of retinal arteries and the vessels extending from the optic disc to macula is smaller in eyes with high myopia, while the venous tortuosity has no change. The bifurcation angle of retinal arteries in the superior nasal and inferior nasal field was smaller in eyes with high myopia, while the venous tortuosity has no change. The bifurcation angle of retinal veins in the superior temporal and inferior temporal field was larger in eyes with high myopia.
