Continuous-wave and Micropulse 577 nm Yellow Laser Photocoagulation: A Laser for All Reasons
Retinal photocoagulation is effective, but it is also destructive. In the past, the prevailing view was that to be useful, laser therapy had to destroy oxygen-consuming rods and cones or retinal pigment epithelium (RPE) cells that produce angiogenic mediators. That perspective has been disproven now by numerous clinical trials and better understanding of the cellular and molecular changes induc...
متن کاملYellow Pattern 577-nm Micropulse Laser: Treatment of Macular Edema from Radiation Retinopathy – A Case Report
We report a case of a 60-year-old Asian male who developed radiation retinopathy 23 years after initial radiotherapy for nasopharyngeal carcinoma and was successfully treated with yellow pattern 577-nm micropulse laser. Secondary macular edema and visual acuity improved following a single treatment session with minimal scarring. Yellow pattern micropulse laser is a safe and effective treatment ...
متن کاملThe Short-term Efficacy of Subthreshold Micropulse Yellow (577-nm) Laser Photocoagulation for Diabetic Macular Edema
PURPOSE This pilot study aimed to evaluate the efficacy and safety of subthreshold micropulse yellow (577-nm) laser photocoagulation (SMYLP) in the treatment of diabetic macular edema (DME). METHODS We reviewed 14 eyes of 12 patients with DME who underwent SMYLP with a 15% duty cycle at an energy level immediately below that of the test burn. The laser exposure time was 20 ms and the spot dia...
متن کاملSubthreshold 577 nm micropulse laser treatment for central serous chorioretinopathy
PURPOSE To compare the efficacy of the subthreshold micropulse laser (SML) to conventional laser (CL) in treating focal leakages of the retinal pigment epithelium (RPE) in the eyes with central serous chorioretinopathy (CSC). METHODS Twenty-nine eyes of 28 patients with CSC and typical focal leakage were treated with CL or SML. Both treatments were made with a 577 nm yellow laser (CL: NIDEK M...
متن کاملTherapeutic window of retinal photocoagulation with green (532-nm) and yellow (577-nm) lasers.
BACKGROUND AND OBJECTIVE The 577-nm (yellow) laser provides an alternative to the 532-nm (green) laser in retinal photocoagulation, with potential benefits in macular treatment and through ocular opacities. To assess relative risk of thermomechanical rupture of Bruch's membrane with yellow laser in photocoagulation, the therapeutic window, the ratio of threshold powers for mild coagulation and ...
