要約 背景:高出力で短照射時間で複数のショットを行う光凝固法としてpattern scan laser(PASCAL®)が最近使用可能になった。目的:両眼に糖尿病網膜症がある患者の一眼に通常の光凝固,他眼にPASCAL®による光凝固を行った成績の報告。症例:糖尿病網膜症があり,光凝固が必要と判断された10例20眼を対象とした。一眼には従来法であるシングルショット,200μm,200mW,0.2秒,3分割の汎網膜光凝固を行い,他眼には200μm,400mW,0.02秒,2分割のパターン照射を行った。24週までの経過を追い,蛍光眼底造影で光凝固の効果を判定した。結果:施術時間はパターン照射が有意に短く,視力,中心窩網膜厚,疼痛の自覚,汎網膜光凝固の効果は同等であった。結論:PASCAL®による汎網膜光凝固では施術時間と回数が少なく,従来の方法と同等な効果が得られた。
Abstract. Purpose:To report the outcome of panretinal photocoagulation(PRP)by pattern scan laser and conventional laser for diabetic retinopathy. Cases and Method:This prospective study was made on 20 eyes of 10 patients. One eye received PRP as single shots,200μm in size,200 mW for 0.2 sec in 3 sessions. The fellow eye received PRP by pattern scan laser with 200μm in size and 400 mW for 0.02 sec in 2 sessions. Cases were followed up for 24 weeks. Effect of PRP was evaluated by fluorescein angiography. Results:Duration of treatment was significantly shorter in eyes treated by pattern scan laser than in fellow eyes. There was no difference between the two methods regarding visual acuity,foveal thickness,subjective pain,or effect of PRP. Conclusion:PRP by pattern scan laser resulted in shorter duration of treatment and in same effect as by conventional laser.
