In 105 eyes of 68 highly myopic patients with focal chorioretinal atrophy in posterior staphyloma, the shape of the staphyloma and the process of backward elongation were studied. Indirect binocular ophthalmoscopy (and in some cases slit-lamp biomicroscopy of the fundus.) was used to observe the staphyloma. The results were as follows: 1) In 72.4% of all the eyes, patchy atrophy (part or whole) protruded or became dented in the staphyloma. The protrusion and the dent did not correlate with age. The refraction of eyes which had protruded patchy atrophy was significantly stronger than those which had dented patchy atrophy. The axial length of eyes which had protruded patchy atrophy was also significantly longer. 2) The protrusion and the dent were localized in patchy atrophy with a diameter of over 1.5 PD. 3) In 80.3% of peripapillary chorioretinal atrophic cases, atrophy protruded or became dented in the staphyloma. 4) In 43.8% the limits of the location of retinal blood vessels formed part of the borderlines of the staphyloma. 5) In 28.6%, steps were created in the staphyloma by the limits of the location of retinal blood vessels. As the staphyloma progresses, patchy atrophy, annular-type myopic crescents, and the location of retinal blood vessels influence the shape of the staphyloma.
在68例患有后巩膜葡萄肿并伴有局灶性脉络膜视网膜萎缩的高度近视患者的105只眼中，研究了葡萄肿的形状和向后延伸的过程。使用间接双眼检眼镜检查（在某些情况下还使用眼底裂隙灯生物显微镜检查）来观察葡萄肿。结果如下：1）在所有眼中，72.4%的眼中，片状萎缩（部分或全部）在葡萄肿中突出或凹陷。突出和凹陷与年龄无关。有突出片状萎缩的眼睛的屈光度明显强于有凹陷片状萎缩的眼睛。有突出片状萎缩的眼睛的眼轴长度也明显更长。2）突出和凹陷位于直径超过1.5视盘直径的片状萎缩处。3）在80.3%的视乳头周围脉络膜视网膜萎缩病例中，萎缩在葡萄肿中突出或凹陷。4）在43.8%的病例中，视网膜血管位置的界限构成了葡萄肿边界的一部分。5）在28.6%的病例中，视网膜血管位置的界限在葡萄肿中形成了台阶。随着葡萄肿的进展，片状萎缩、环形近视性弧形斑和视网膜血管的位置会影响葡萄肿的形状。
