  • Only one eye may be randomized per participating individual, in case both are eligible, the investigator may choose either eye according his/her criteria.
  • BVCA according to ETDRS between \<78 (20/32 or worse) and \>24 (20/320 or better) within 8 days prior to the randomization.
  • Clinically evident diabetic macular edema, with central macular thickening.
  • Diabetic macular edema demonstrated in OCT scan (macular central thickness \> 300 μm for men and \> 290 μm for women) within 8 days prior to the randomization.
  • Presenting characteristics that allow an adequate fundus examination (transparent means, adequate pupil dilation, etc).

Exclusion

  • Chronic renal disease with renal insufficiency that requires dialysis or transplant.
  • Individuals with conditions that may compromise their participation during the span of the study (unstable concomitant diseases, possible change of residence, etc)
  • Individuals with a poor glycemic control who have started insulin treatment within 4 months previous to the study.
  • Participation in another clinical study (at least 90 days must have elapsed between the finalization of his/her participation in a previous essay and randomization in the present study).
  • Known allergies to the treatment.
  • Poorly controlled blood pressure (average of 3 readings while sitting with ≥160 mmHg systolic or ≥100 mmHg diastolic in the selection visit.
  • Heart attack or other cardiovascular event (cerebral vascular disease, transitory ischemia, hospitalization for cardiac insufficiency) during the 4 months prior to the start of the study, or patients with active myocardial insufficiency.
  • Previous systemic treatment with VEGF-related medications within 4 months prior to the start of the study.
  • Women of child-bearing age who are pregnant, lactating of planning to get pregnant within the time span of the study.
  • Known allergy to anesthetic medications used during the procedures, intravitreal injection and photocoagulation.
  • Diagnosis of non-diabetic macular edema.
  • Ophthalmic conditions that interfere with the evaluation of BCVA (for example: foveal atrophy, pigmentary abnormalities, dense foveal exudates, etc)
  • Additional conditions to DM that may compromise the evaluation of the edema (for example: venous occlusions, uveitis or other inflammatory diseases, neovascular glaucoma, etc)
  • Lens opacities that according to the LOCS III classification system exceed one or more of the following: \> NO3C3, \> C2, \> P1.
  • Previous history of anti-VEGF treatment for diabetic macular edema or any treatment for diabetic macular edema within 4 months prior to the start of the study (corticosteroids, photocoagulation, etc)
  • Anticipation of the need of panphotocoagulation (for example: proliferative diabetic retinopathy or any other indication) during the period of the study or history of panphotocoagulation within the 4 months prior to the start of the study.
  • History of ocular surgery (cataract extraction, any intraocular surgery, aphakia, etc) within 4 months prior to the start of the study, or planned to occur within the time span of the study.
  • Intraocular pressure \> 21 mmHg, measured through Goldmann tonometry during the selection visit.
  • Presence of macular ischemia or important loss of perifoveal capilaries (avascular foveal zone greater than 350 μm) demonstrated through fluorescein angiography during the selection visit.
  • Evidence of macular traction and hyaloid thickening in OCT scan.
  • History of YAG capsulotomy within 2 months prior to the randomization.
  • Evidence of external ocular infections or any important disease of the ocular surface.
  • History of vitrectomy.
