A 40-year-old man had persistent central serous chorioretinopathy at the foveal region for 20 months. The pretreatment best-corrected visual acuity was 0.3. The leaking point was close to the fovea, making the use of argon laser photocoagulation treatment unsafe. Transpupillary thermal therapy with diode laser (power setting = 120 mW, spot size = 1.2 mm, and duration = 60 seconds) was performed to cover the whole detached area. The subretinal fluid decreased 1 week later. Fluorescein angiography 2 months later revealed neither further leakage nor any subretinal fluid. After 3 months of follow-up, best-corrected visual acuity improved to 0.4. Transpupillary thermal therapy may be a useful alternative for the treatment of chronic, persistent central serous chorioretinopathy at the fovea.
一名40岁男性，其黄斑区持续性中心性浆液性脉络膜视网膜病变已持续20个月。治疗前最佳矫正视力为0.3。渗漏点靠近黄斑，使用氩激光光凝治疗不安全。采用二极管激光经瞳孔温热疗法（功率设置 = 120 mW，光斑大小 = 1.2 mm，持续时间 = 60秒）覆盖整个脱离区域。1周后视网膜下液减少。2个月后的荧光素血管造影显示既无进一步渗漏，也无任何视网膜下液。经过3个月的随访，最佳矫正视力提高到了0.4。经瞳孔温热疗法可能是治疗黄斑区慢性、持续性中心性浆液性脉络膜视网膜病变的一种有效替代方法。
