NCT04857099

Brief Summary

The Navilas® micropulse laser can be used to treat patients with macular edema and good visual acuity, which therefore do not fall within the indications for conventional treatments by intravitreal injections. The CHU Brugmann Hospital is the only center to own this laser in Belgium.This study aims to evaluate the efficacy of this laser.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Retrospective study including 23 files of patients treated with the Navilas ® micropulse laser, in the period from 04/25/2018 to 11/10/2020

You may qualify if:

  • Diffuse macular edema without focal edema source accessible by focal laser (e.g. capillary telangiectasia)
  • Central retinal thickness ≤ 400microns.
  • Patient does not meet the reimbursement criteria for intra-vitreous injections(IVI) of anti-VEGF (eg AV\> 5/10).
  • IVI are contraindicated.
  • Physician considers that it is preferable to space out the injections because of the side effects (eg. ocular disturbance during IVI, eye pain, sensation of a foreign body, spots in the visual field generating a visual gene etc.)
  • Patient wishing to space the anti-VEGF IVI.

You may not qualify if:

  • Macular edema of a different etiology than diabetic macular edema or venous thrombosis (e.g. cataract extraction, vitreomacular traction, epiretinal membrane etc.)
  • Central retinal thickness \> 400 microns.
  • The eye presents a focal edematous maculopathy accessible to conventional laser.
