The authors reviewed the records of 302 eyes of 185 patients with diffuse diabetic macular edema with or without cystoid macular edema treated with modified grid laser photocoagulation between the years 1981 and 1990. Three years after initial grid treatment, visual acuity was improved in 14.5%, unchanged in 60.9%, and worse in 24.6% of eyes. The average number of treatments per eye was 1.9. These results show that in assessing long-term visual outcome, modified grid laser photocoagulation is an effective modality in maintaining or improving visual acuity in eyes with diffuse diabetic macular edema. The effectiveness demonstrated in this study is without comparison with control subjects with no treatment or comparison with other treatment techniques.
作者回顾了1981年至1990年间接受改良格栅激光光凝治疗的185例弥漫性糖尿病性黄斑水肿伴或不伴黄斑囊样水肿患者的302只眼的记录。初次格栅治疗三年后，14.5%的患眼视力提高，60.9%的患眼视力不变，24.6%的患眼视力下降。每只眼平均治疗次数为1.9次。这些结果表明，在评估长期视力预后时，改良格栅激光光凝是维持或提高弥漫性糖尿病性黄斑水肿患眼视力的一种有效方式。本研究中所证明的有效性未与未治疗的对照受试者进行比较，也未与其他治疗技术进行比较。
