Summary
The study involves the enrollment of patients over 18 years of age with diabetic macular
edema(DME). Patients with one study eye will be randomly assigned (stratified by visual
acuity and prior laser) with equal probability to one of the three treatment groups:
1. Laser photocoagulation
2. 1mg intravitreal triamcinolone acetonide injection
3. 4mg intravitreal triamcinolone acetonide injection
For patients with two study eyes (both eyes eligible at the time of randomization), the right
eye (stratified by visual acuity and prior laser) will be randomly assigned with equal
probabilities to one of the three treatment groups listed above. The left eye will be
assigned to the alternative treatment (laser or triamcinolone). If the left eye is assigned
to triamcinolone, then the dose (1mg or 4 mg) will be randomly assigned to the left eye with
equal probability (stratified by visual acuity and prior laser).
The study drug, triamcinolone acetonide, has been manufactured as a sterile intravitreal
injectable by Allergan. Study eyes assigned to an intravitreal triamcinolone injection will
receive a dose of either 1mg or 4mg. There is no indication of which treatment regimen will
be better.
Patients enrolled into the study will be followed for three years and will have study visits
every 4 months after receiving their assigned study treatment. In addition, standard of care
post-treatment visits will be performed at 4 weeks after each intravitreal injection.
