Background and Objective:Subthreshold laser therapy has emerged as a therapeutic alternative to traditional laser photocoagulation for certain ophthalmic diseases including central serous chorioretinopathy(CSCR),diabetic macular edema(DME),macular edema secondary to branch retinal vein occlusion(BRVO),and age-related macular degeneration(AMD).The objective of this paper is to review and discuss the clinical applications of subthreshold laser and the mechanisms of different subthreshold laser techniques including subthreshold micropulse laser(SMPL),selective retina therapy(SRT),subthreshold nanosecond laser(SNL),endpoint management(EpM),and transpupillary thermotherapy(TTT).Methods:A narrative review of English literature and publicly available information published before November 2021 from literature databases and computerized *** discuss the currently available subthreshold laser systems and the advancements made to perform different subthreshold laser techniques for various ophthalmic *** highlight various clinical studies and therapeutic techniques that have been conducted to further understand the effectiveness of subthreshold laser in the clinical *** conclude the article by covering emerging subthreshold laser systems that are currently being developed for future clinical *** PubMed database was utilized for peer-reviewed articles and pertinent information on subthreshold systems was cited from publicly available online websites covering specific *** Content and Findings:Various subthreshold laser systems have been developed to treat certain retinal *** systems are currently in development for future clinical ***:While conventional laser photocoagulation has been effective in treating various retinal diseases,subthreshold laser systems aim to provide a therapeutic effect without visible signs of damage to the underlying *** technology may be particularly effective in treating macular di
