Changing the paradigm for AMD
Until now, therapies for Age-Related Macular Degeneration (AMD) have only focused on late stage treatments that attempt to manage the symptoms experienced by patients — by which stage vision loss, and or damage has already occurred.
Currently, the sole option for the more aggressive wet form of AMD is the administration of expensive and invasive anti-VEGF injections. These are only suitable for advanced or end stage disease, and merely address complications associated with AMD.
In contrast, 2RT® Retinal Rejuvenation Therapy enables ophthalmologists the potential to intervene earlier in the disease process with the aim of slowing the degeneration process.
Clinically proven to delay AMD
The Laser Intervention in Early AMD (LEAD) clinical trial, a large randomized, controlled clinical trial, has demonstrated the potential for 2RT® to significantly reduce the rate of disease progression in a specific group of intermediate AMD patients.1 The trial, which enrolled 292 patients, examined whether the application of 2RT® could delay progression of intermediate AMD to late-stage disease. Each participant was randomly assigned to 2RT® treatment, or a sham laser procedure (placebo group) and received treatment and/or follow-up over three years.
Despite not reaching statistical significance, when considering all patients enrolled in the trial, there was a trend to delay progression from early to late stage AMD in those treated with 2RT® Retinal Rejuvenation Therapy.
Post hoc analyses showed that in patients who did not have coexistent reticular pseudodrusen (RPD), a fatty deposit that is associated with later stages of AMD (76% of patients enrolled), treatment with 2RT® resulted in a clinically meaningful 77% reduction in the rate of disease progression.
Taking the heat out of photocoagulation
For Diabetic Macular Edema and Proliferative Retinopathy, CW retinal photocoagulation remains a mainstream pathway. The use of CW photocoagulation to treat retinal disease represents a two-fold challenge. First — the treatment causes irreversible collateral damage to retinal tissue, and, second — it is an often painful procedure for the patient.
Clinical studies have shown 2RT® can deliver a therapeutic benefit for the treatment of Clinically Significant Macular Edema (CSME) similar to that achieved through thermal retinal photocoagulation laser treatment, but without the collateral damage associated with the conventional method. Using 500 times less energy than retinal photocoagulation, 2RT® eliminates the incidence of heat damage to the retina and surrounding cells.1
Gentle stimulation, natural renewal
Retinal Rejuvenation Therapy stimulates a biological healing process that results in cellular rejuvenation, renewing the entire transport mechanism of the retina and improving the hydraulic conductivity of Bruch’s Membrane. In suitable patients, this rejuvenation process preserves or improves functional vision and reduces disease progression.
Ellex 2RT® utilizes an ultra-short nanosecond laser pulse that allows the precise and specific delivery of laser energy to nano-sized targets within the cellular structure of ageing RPE cells – without causing collateral damage to the overlying photoreceptor rods and cones of the retina.
“… if we can slow down the basal rate of Bruch’s Membrane aging with 2RT® and restore function to what it was when the patient was in their teens, we should be able to significantly delay AMD onset.”
