To investigate the influence of the intensity of coagulation spots on retinal function and the clinical course after panretinal argon laser photocoagulation in diabetic retinopathy, we conducted a prospective study in 24 eyes of 12 diabetics. One eye was treated with moderate spots (average: 300 mW), the fellow eye was coagulated with intense spots (average: 600 mW). The spot size was identical in both eyes. Subjective parameters (visual acuity, perimetry), as well as objective functions (ERG, EOG) and the clinical course, were studied preoperatively and on a regular base with a follow-up of 12 months. Visual acuity and fundus findings deteriorated less often in eyes coagulated with intense spots. Visual field loss, however, was more prevalent in eyes treated with intense spots. Early treatment complications only occurred with high-energy coagulation. For this reason, high-energy spots should not be used even though they might be indicated theoretically.
为研究糖尿病性视网膜病变行全视网膜氩激光光凝术后，凝固斑强度对视网膜功能及临床病程的影响，我们对12例糖尿病患者的24只眼进行了一项前瞻性研究。一只眼用中等强度光斑（平均：300 mW）治疗，另一只眼用高强度光斑（平均：600 mW）凝固。两只眼的光斑大小相同。术前及术后定期随访12个月，研究主观参数（视力、视野）、客观功能（视网膜电图、眼电图）及临床病程。高强度光斑凝固的眼视力和眼底改变恶化的情况较少。然而，高强度光斑治疗的眼视野缺损更为普遍。早期治疗并发症仅发生于高能凝固。因此，即使理论上可能有指征，也不应使用高能光斑。
