About this study
Official title: Aflibercept Plus Micropulse Laser Versus Aflibercept Monotherapy for Diabetic Macular Edema. One Year Results of a Randomized Clinical Trial
Purpose: To evaluate the role of adjuvent micropulse laser with Aflibercept injections in the management of treatment naïve centre involving DME, looking at decreased treatment burden and increased efficacy as outcomes.
Methods: This was a prospective, single centre, randomized trial that included 40 eyes (40 patients) with previously untreated centre involved DME. Patients were randomly assigned to receive either Aflibercept plus micropulse laser (group A) or Aflibercept monotherapy (group B).
Read the detailed description
Patients were randomly distributed in a 1:1 ratio between the two studied groups. Group A received 3 monthly injections of Aflibercept 2 mg/0.05 mL (Eylea; Bayer, Berlin, Germany) as a loading dose, followed one month later by one 577 nm yellow micropulse laser session with monthly PRN Aflibercept injections. Group B received 3 monthly injections of Aflibercept 2 mg/0.05 mL as a loading dose, followed by monthly PRN Aflibercept injections. Patients in both groups were assessed one month after the end of loading phase; At this point, group A received the micropulse laser session and started PRN Aflibercept injections, while group B started PRN Aflibercept injections without receiving the micropulse laser session. After that, both groups were followed for 12 months.

micropulse laserDevice
Micropulse session details:
Mainster focal grid contact lens (×1.05 laser magnification) was used to perform laser. The 577-nm yellow laser (OcuLight SLx, Iridex Corp., Mountain View, California, USA) was used. Fixed treatment parameters were used in all cases: 200-μm spot size, 200-ms exposure duration, 400-mW power, and a 5% duty cycle. Confluent applications with no spacing were administered using 5x5 grid pattern over the entire edematous area including the fovea.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number of Aflibercept injections in both groups (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2019.
