Our hypothesis is that implementing laser photocoagulation (IGTL) as an adjunctive treatment to intravitreal injections should lead to a significant reduction in the need for intravitreal injections in patients with diabetic macular edema without adverse consequences for visual acuity.
Full description
This study will be French, multicenter parallel group, 2-arms, randomized, sham laser-controlled, double-blind trial evaluating the effect of IGTL as an adjunctive procedure to intravitreal injections in patients with DME.
Acts which are the subject of the study: indocyanine green-Guided Targeted Laser photocoagulation (IGTL): this combines routine procedures, that are, the detection of macro-aneurysms by ICG angiography, laser photocoagulation and optional post-laser verification of the effectiveness of the photothrombosis by OCT.
Study act: the treatment study includes a baseline laser treatment (experimental group) or sham laser (control group) at randomization, repeated if needed 3 month later, administered in combination with anti VEGF treatment, consisting of 3 monthly injections in the first 3 months, and a maintenance phase with monthly visits where retreatment is administered as needed through a PRN regimen, based on morphological (retinal thickness on OCT) and functional (visual acuity) criteria.
To evaluate the interest of IGTL in real conditions, the choice of the anti VEGF treatment used for intravitreal injection (Ranibizumab or Aflibercept, which have French marketing authorizations) is left to each investigator (equivalent therapeutic efficacy). Bevacizumab is ruled out due to its lower efficacy compared with Aflibercept among eyes with worse baseline VA, that represent the majority of the patients in our study. In addition, bevacizumab is currently off-label in France for DME If both eyes are eligible at the time of randomization, only one eye will be included and analyzed. However, the fellow eye will be treated with the randomization-assigned treatment and the testing will be performed on each eye.
Risks and constraints involved in the study: these procedures are commonly done in ophthalmology care settings; no additional risk is expected due to the study.
Expected benefits for the participants and for the company: These procedures are commonly done in ophthalmology care settings; no additional risk is expected due to the study.
