No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
Multicentre randomized controlled trial to evaluate whether 5 monthly fixed dosing of 700 µg Dexamethasone Posterior Segment Drug Delivery System (Ozurdex) is as efficacious as Optical coherence tomography (OCT)-guided PRN dosing in patients with refractory diabetic macular edema.

Eligibility Criteria
Inclusion Criteria
- Subjects of either sex aged 18 years or over
- Diagnosis of diabetes mellitus (type 1 or type 2).
- Best corrected visual acuity in the study eye between ≥34 and ≤73 ETDRS letters at 1m at baseline attributable to diabetic macular edema (DME)
- On clinical exam at baseline in the study eye, retinal thickening due to diabetic macular oedema involving the centre of the macula and OCT central subfield > 300 microns despite previous therapy.
- Media clarity, pupillary dilation, and subject cooperation sufficient for adequate fundus photographs.
- Ability to return for study visits
- Visual acuity in fellow eye ≥ 2/60
- Ability to give informed consent throughout the duration of the study
Main Exclusion Criteria:
- Macular ischaemia
- Macular oedema is considered to be due to a cause other than diabetic macular oedema.
- Co-existent ocular disease
- An ocular condition is present (other than diabetes) that, in the opinion of the investigator, might affect macular oedema or alter visual acuity during the course of the study.
- A substantial cataract that, in the opinion of the investigator, is likely to be decreasing visual acuity by 3 lines or more.
