    New retinal laser therapy options offer improvements to macular disease management

    A titratable tissue-sparing approach to retinal laser therapy provides safer treatment for the macula

    Laser photocoagulation has been used for many retinal applications; in the past, it was applied to treat choroidal neovascularisation in age-related macular degeneration (AMD). However, although the technique is effective, intense photocoagulation leaves a scar and associated scotoma.

    Today, anti-vascular endothelial growth factor (anti-VEGF) injections are favoured over laser treatment for neovascularisation, as well as branch retinal vein occlusion and proliferative diabetic retinopathy.1

    The Early Treatment Diabetic Retina Study (ETDRS) in the 1980s and, more recently, the Diabetic Retinopathy Clinical Research Network study, found grid photocoagulation to be efficient for the treatment of diabetic macular oedema (DMO), but its mechanism of action has been poorly understood.2 Now, evidence is increasing that macular diseases can be treated using thermal stress without tissue damage.
