Visual outcomes and anatomic changes after sub-threshold micropulse yellow laser (577-nm) treatment for chronic central serous chorioretinopathy: long-term follow-up.

摘要: To analyze the long-term efficacy of 577 nm sub-threshold micropulse yellow laser (SMYL) in treatment chronic central serous chorioretinopathy (CCSC) and to evaluate anatomic outcome, visual results safety profile treatment. This prospective study assessed 39 eyes patients with non-resolving CCSC lasting more than three months. All were treated by using SMYL system 5% duty cycle (DC) each was monitored monthly. The main outcome measures best-corrected acuity (BCVA), contrast sensitivity (CS) subretinal fluid (SRF) height, macular thickness (CMT), volume (CMV), total (TMV), subfoveal choroidal (SFCT) measured spectral domain optical coherence tomography (SD-OCT). median follow-up time period 17.82±0.42 (13−23 months) BCVA improved significantly at final comparison baseline visit (P<0.01) 35 (89.7%) 4 (10.3%) stable. CMT, CMV, TMV before 369 μm, 0.30 mm3, 9.86 mm3, 250 μm, 0.19 mm3, 8.76 mm3 follow-up, respectively (P<0.01 for all these parameters). Initial SFCT recorded as 364 μm 342 μm (P<0.001). Results suggest that is an effective method response rapid procedure safe manage eyes.
