• Status: Unknown status
• Trial end date: 2020-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The aim of this study is to evaluate the one-year visual outcome and prognostic factors after intraocular injections of ranibizumab under pro re nata treatment regimen for the patients with diabetic macular edema (DME).

• Phase: Phase 1/Phase 2

Details

• Lead Sponsor: Sun Yat-sen University
• Treatments: Ranibizumab

Criteria

Inclusion Criteria:

• 1) patients (aged>18 years) with DME who had a best-corrected visual acuity (BCVA) between 20/32 and 20/200, and CRT≥300μm; 2) clinically significant DME confirmed by both fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) (Spectralis HRA+OCT; Heidelberg Engineering, Germany); 3) decreased vision caused by foveal thickening from DME, which could not be explained by any other cause.

Exclusion Criteria:

• 1) previous anti-VEGF or laser treatment; 2) proliferative diabetic retinopathy who required immediate panretinal photocoagulation; 3) active proliferative diabetic retinopathy; 4) other causes for macular edema, for example, branch retinal vein occlusion; 5) other causes of visual loss in the study; 6) unstable systemic conditions, for example, uncontrolled blood pressure, stroke, renal or kidney failure.
