The ocular findings in 127 eyes of 69 cases (average 11.6 +/- 3.7 years old) with retinopathy of prematurity (ROP) and treated with xenon photocoagulation between 1970 to 1983 were studied. Chorioretinal changes observed after the photocoagulation therapy revealed that photocoagulation spots gradually transformed from round to long oval forms in the sagittal direction. The photocoagulated lesions became extremely atrophic and larger after several years. In addition, band-shaped retinochoroidal atrophies were found adjacent to photocoagulation spots in 10 eyes (7.9%). Furthermore, vascular anastomoses between retinal and choroidal vessels were demonstrated at scars after treatment by fluorescein angiography. Anastomoses between retinal arteries and choroidal vessels were found in 18 eyes among 71 eyes (25.4%), and anastomoses between retinal veins and choroidal vessels were present in 50 eyes among the 71 eyes (70.4%). These changes may be the result of xenon photocoagulation on the developing premature retina and choroid. However, visual acuities were 0.7 or better in 111 eyes (87.4%). Refractions at the aged six years old were between - 3 to +2.75 diopters in the 94 eyes (83.9%) among the 112 eyes.
对1970年至1983年间69例（平均年龄11.6±3.7岁）患有早产儿视网膜病变（ROP）且接受氙光凝治疗的127只眼的眼部检查结果进行了研究。光凝治疗后观察到的脉络膜视网膜变化显示，光凝斑在矢状方向上逐渐从圆形转变为长椭圆形。数年后，光凝病变变得极度萎缩且面积增大。此外，在10只眼（7.9%）中发现光凝斑附近有条状视网膜脉络膜萎缩。此外，通过荧光素血管造影显示，治疗后瘢痕处视网膜和脉络膜血管之间存在血管吻合。在71只眼中，18只眼（25.4%）发现视网膜动脉与脉络膜血管之间有吻合，71只眼中50只眼（70.4%）存在视网膜静脉与脉络膜血管之间的吻合。这些变化可能是氙光凝作用于发育中的早产儿视网膜和脉络膜的结果。然而，111只眼（87.4%）的视力为0.7或更好。在112只眼中，94只眼（83.9%）6岁时的屈光度在-3至+2.75屈光度之间。
