Intravitreal Ranibizumab Versus Its Combination With Dexamethasone in The Treatment of Diabetic Macular Edema
Diabetic Macular Edema
About this trial
This is an interventional treatment trial for Diabetic Macular Edema
Eligibility Criteria
Inclusion Criteria:
- Diabetic macular edema with central macular thickness of 300 μm or greater (as measured by spectral domain optical coherence tomography [OCT]).
- Best corrected visual acuity of 6/12 or less.
Exclusion Criteria:
● History of any treatment for DME (including grid or focal laser photocoagulation) within the last 6 months
- History of panretinal photocoagulation within the last 6 months.
- PDR as indicated with Fluorescein Angiography as it will require PRP which may affect DME.
- Macular ischemia, as indicated with Fluorescein Angiography.
- Cataract surgery within three months or cataract that requires surgical intervention during the follow-up period.
- Pseudophakia with Irvine Gass syndrome, as indicated with Fluorescein Angiography.
- Vitreomacular traction syndrome.
- Other causes of macular edema (eg. CRVO, CNV, uveitis, etc).
- Glaucoma, whether suspected or confirmed.
- Significant media opacity.
- Patients with ocular or periocular infections, or infection in the other eye
- Signs of Active or resolved uveitis and intraocular inflammation.

Active Comparator
Active Comparator
The first group, Lucentis alone group
The second group, Lucentis dexamethasone group
The first group received 3 monthly intravitreal injections of 0.5 mg in 0.05 mL ranibizumab alone (Lucentis, by Novartis), aspirated from vial through 5-micron sterile filter needle (19-gauge × 1-1/2 inch), with a 1-mL syringe and injected through a 30-gauge × ½ inch sterile injection needle.
The second group received monthly intravitreal injections of the same dose of ranibizumab combined with 0.4 mg in 0.1 ml dexamethasone (Dexamethasone sodium phosphate, Amriya Pharmaceuticals, Cairo, Egypt) in a separate 1ml syringe with 27- gauge × ½ inch sterile injection needle, followed by 2 Intravitreal ranibizumab, 1 month apart (with dexamethasone if follow up OCT shows less than 10% improvement from baseline i.e., PRN).
