Subthreshold Micropulse Yellow Laser (577 nm) for Idiopathic Macular Telangiectasia Type 1 Resistant to Intravitreal Injection

Yellow Subthreshold Micropulse Laser in Retinal Diseases: An In-Depth Analysis and Review of the Literature

“…Therapeutic options consist of laser photocoagulation, intravitreal injections of steroids or anti-VEGF agents [ 132 ]. Kang et al reported a case of a 54-year-old man with type 1 MacTel in the left eye [ 133 ]. BCVA was 20/800 at baseline, and spectral domain (SD)-OCT showed severe CME, for which he underwent two ineffective intravitreal injections of bevacizumab before receiving three YSML sessions.…”

“…However, after 1 year the treated area showed focal atrophic changes, which the authors claimed to potentially be associated with the chronic CME but they could not exclude that it was triggered by repeated YSLT. Nevertheless, at 3-year follow-up BCVA still improved to 20/40 in the treated eye [ 133 ].…”

Multiple-Session Subthreshold Micropulse Laser Therapy for Exudative Perifoveal Vascular Anomalous Complex: A Case Report

“…We followed a similar SMPL protocol as that described in previous reports. 8,9 We increased the duty cycle and duration after the first session of SMPL on the aneurysmal lesion more repeatedly to expect closure of aneurysm. After treatment, the involution of aneurysm was achieved; however, it was not clear whether it means preclinical nonexudative stage PVAC stage or complete resolution.…”
