Brief Summary

Macular edema is the main cause of vision loss in diabetic patients. Its treatment is mainly based on laser photocoagulation, but has limited results. Alternative treatment are under investigation, such as vitrectomy and intravitreal injections of triamcinolone .The aim of VITRILASE is to compare the efficacy of these two treatments to laser photocoagulation for diabetic macular edema.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient with type 1 or type 2 diabetes
  • Visual acuity (VA) : 0.1≤ VA \< 0.5 (35 ≤ ETDRS score \< 70)
  • Patient with diffuse diabetic macular edema , as defined by :§ Retinal thickening involving the center of the macular on biomicroscopy§ AND diffuse leakage on fluorescein angiography .
  • Macular thickness in the central area 1000 µm in diameter ³ 300 µm.
  • Patient with :· Either diffuse diabetic macular edema · Or combined diffuse and focal diabetic macular edema with persistent diffuse macular edema 6 months after laser treatment of the focal edema .
  • Systolic blood pressure ≤ 160 mmHg and diastolic blood pressure ≤ 90 mmHg.,
  • HbA1c \< 10%.

You may not qualify if:

  • Patient with tractional diabetic macular edema, as defined by· A taut, thickened posterior hyaloid on biomicroscopy AND/OR· a thickened , highly reflective posterior hyaloid on OCT , partially detached from the posterior pole, and exerting a traction on the macula
  • Active proliferative diabetic retinopathy (ETDRS stage 61 or more severe)
  • Structural damage to the center of the macula in the study eye likely to preclude improvement in visual acuity following the resolution of macular edema, including atrophy of the retinal pigment epithelium, subretinal fibrosis, laser scar(s), or organized central hard exudate plaque³ 1 disk area
  • Hypertensive retinopathy
  • Epiretinal membrane.
  • Rubeosis irides .
  • Patient requiring immediate panretinal photocoagulation or panretinal photocoagulation performed within the past 6 months .
  • History of chronic glaucoma in the study eye
  • History of elevated intraocular pressure ≥30 mm Hg and/or alteration of visual field
  • Concomitant therapy with systemic or topical ocular corticosteroids within the last 15 days .

  • Aphakia
  • Patient with pseudophakic macula edema
  • Unstable medical status including glycemic control and blood pressure. Patients in poor glycemic control who, within the last 4 months, initiated intensive insulin treatment (a pump or multiple daily injections) should not be enrolled.
  • Chronic renal failure
