To compare the safety and efficacy of Pascal laser photocoagulation in comparison with the conventional laser photocoagulation in the treatment of diabetic retinopathy.
A prospective randomized case series study was done on 120 procedures done in 120 patients divided into two main groups, group A, patients undergoing focal or modified grid macular laser and group B, patients undergoing panretinal photocoagulation (PRP). Each of the two groups were subdivided into two subgroups randomly in the first we used conventional laser photocoagulation (groups A1 and B1) and in the other we used Pascal laser photocoagulation (groups A2 and B2).
Procedures in groups A1,2 and in groups B1,2 had successful outcomes. Significantly higher powers were required with the Pascal (groups A2 and B2) than with conventional laser (groups A1 and B1) (p < 0.001) in eyes that underwent PRP and focal/modified grid macular treatment with both systems. No adverse events were noted in all groups.
The Pascal photocoagulator is safe, rapid, effective, with rapid learning and had short exposure time. Although the shorter pulse duration of the Pascal necessitates the use of a higher power, it is not associated with adverse effects.
比较帕斯卡激光光凝术与传统激光光凝术治疗糖尿病性视网膜病变的安全性和有效性。
对120例患者进行的120次手术开展了一项前瞻性随机病例系列研究，这些患者被分为两个主要组，A组为接受局灶性或改良格栅状黄斑激光治疗的患者，B组为接受全视网膜光凝（PRP）的患者。两组中的每一组又被随机细分为两个亚组，第一组我们使用传统激光光凝术（A1组和B1组），另一组我们使用帕斯卡激光光凝术（A2组和B2组）。
A1、A2组以及B1、B2组的手术均取得成功结果。在接受PRP以及使用这两种系统进行局灶性/改良格栅状黄斑治疗的眼中，帕斯卡激光（A2组和B2组）所需的能量显著高于传统激光（A1组和B1组）（p < 0.001）。所有组均未观察到不良事件。
帕斯卡光凝器安全、快速、有效，学习曲线短且曝光时间短。尽管帕斯卡激光的脉冲持续时间较短需要使用更高的能量，但它并未产生不良反应。
