观察白内障术后糖尿病视网膜病变的光凝治疗效果及光凝后的远期复明效果 ,探讨光凝治疗的时机 ,影响光凝的因素。方法 :对我院 5年来行白内障手术的伴有糖尿病视网膜病变且具有光凝指征的病人 ,将其分为两组 ,白内障术后行光凝治疗组5 3例 ,未行光凝治疗组 45例。结果 :白内障术后早期光凝治疗的病人 ,糖尿病视网膜病变稳定 ,黄斑水肿消褪或减轻 ,视力保持稳定。未行光凝治疗的病人 ,视网膜病变加重 ,视力下降甚至失明。结论 :伴有糖尿病视网膜病变的白内障病人行白内障手术后 ,如有光凝指征 ,应尽早行光凝治疗。这对于控制或延缓糖尿病视网膜病变的进展 ,稳定病人视力 ,提高这些白内障病人的远期复明效果 ,有重要意义。
To observe the effect of photocoagulation in diabetic retinopathy and the long-term bright effect after photocoagulation to investigate the timing of photocoagulation treatment and the factors affecting photocoagulation. Methods: The patients with diabetic retinopathy with photorefractive indications who underwent cataract surgery in our hospital for 5 years were divided into two groups: 53 patients in the photocoagulation group after cataract surgery and without photocoagulation treatment group 45 cases. Results: In patients with early photocoagulation after cataract surgery, diabetic retinopathy is stable and macular edema fade or relieve, and visual acuity remains stable. Patients without photocoagulation, retinopathy, decreased vision or even blindness. Conclusion: Cataract patients with diabetic retinopathy after cataract surgery, if indications of photocoagulation, phototherapy should be as soon as possible. This is of great importance for controlling or retarding the progress of diabetic retinopathy, stabilizing the patient’s vision, and improving the long-term rejuvenation effect of these cataract patients.
