Infrared light could replace injections to treat macular oedema
A clinical trial at Sydney Eye Hospital is evaluating the safety and efficacy of using infrared light to treat macula oedema from retinal vein occlusions, instead of the current standard treatment of eye injections.
Near infrared light treatment is thought to work by stimulating cellular metabolism and repair.
According to the researchers, retinal vein occlusions typically occur in patients aged over 50 with cardiovascular risk factors such as hypertension, diabetes, high cholesterol, obesity and smoking.
The results of the trial have shown that 12 90-second treatment sessions with infrared light reduced the patients' macular oedema and the subsequent requirement for eye injections.
