目的：评价重度近视合并后葡萄肿患者的视网膜断层扫描特征。方法：对19例(32眼)重度近视合并后葡萄肿患者进行全面眼科检查和光学相干断层扫描研究黄斑的断层图像，患者年龄41~83岁(平均62.7岁)，最佳矫正视力20/500~20/40(平均20/120)，其中有晶状体眼26眼，人工晶状体眼6眼。26只有晶状体眼屈光度在-8~-31度之间，平均-16.7度，6只人工晶状体眼屈光度在-8度以内，有明显的后部葡萄肿，A型超声测量眼轴长度为25.7~32.7 mm，平均29.2 mm。结果：9只眼裂隙灯检查视网膜浅层，光学相干断层扫描发现黄斑中心凹视网膜脱离伴视网膜劈裂8只眼，黄斑中心凹视网膜脱离1只眼。结论：黄斑中心凹视网膜脱离和视网膜劈裂是伴有后部葡萄肿的高度近视眼的常见特征。在高度近视的眼睛，视网膜脱离可能先于黄斑裂孔的形成。《眼科杂志》1999；128：472-476。(C)1999，Elsevier Science Inc.版权所有。)
PURPOSE: To evaluate the tomographic features of the retina in patients with severe myopia and posterior staphyloma.METHODS: In a prospective study of 32 eyes of 19 consecutive patients with severe myopia and posterior staphyloma, we performed complete ophthalmic examinations and studied cross-sectional images of the macula with optical coherence tomography, Patients' age ranged from 41 to 83 years (average, 62.7 years), Best-corrected visual acuity ranged from 20/500 to 20/40 (average, 20/120), The study included 26 phakic and six pseudophakic eyes. The refractive errors of 26 phakic eyes ranged from -8 to -31 diopters (average, -16.7 diopters), Although refractive errors were within -8 diopters in six pseudophakic eyes, the eyes had apparent posterior staphyloma, The axial lengths measured by A-mode ultrasonography ranged from 25.7 to 32.7 mm (average, 29.2 mm). Slit-lamp examination with contact lens showed that none of the eyes had a macular hole.RESULTS: In nine eyes with shallow retinal elevation on slit-lamp examination, optical coherence tomography disclosed a foveal retinal detachment with retinoschisis in eight eyes and a foveal retinal detachment in one eye. Two of the remaining 23 eyes had retinoschisis.CONCLUSIONS: Foveal retinal detachment and retinoschisis are common features in severely myopic eyes with posterior staphyloma. Retinal detachment may precede the formation of a macular hole in severely myopic eyes. (Am J Ophthalmol 1999;128:472-476. (C) 1999 by Elsevier Science Inc. All rights reserved.).
