Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to evaluate if combination of intravitreal ranibizumab with micropulse laser shows non inferiority compared to intravitreal ranibizumab only in diabetic macular edema.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To investigate the efficacy of intravitreal ranibizumab injections compared to combination with Micropulse Laser in Chinese patients with visual impairment in DME.

The result of the study will be used to support new therapy in DME patients in China.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Informed consent form must be signed before any tests or procedures are done
* Male or female of 30 to 80 years of age (inclusive) at the first screening visit
* Diagnosis of type 2 diabetes, with fasting blood glucose≤10mmol/L, HbA1C≤10.0%
* Diabetic medication must be stable for at least 3 months before first screening visit and remain stable during study
* Diagnosis of non-proliferative diabetic retinopathy with diabetic macular edema resulting in visual acuity reduction
* Study eye's BCVA between 24 to 78 ETDRS letters at screening and baseline of the study
* Macular edema of the study eye and central retinal thickness ≥300 µm determined by SD-OCT
* Study eye had not had grid pattern photocoagulation, intraocular surgery, intravitreal corticosteroid injections and intravitreal anti-VEGF injections for at least 3 months before baseline
* Non-study eye's BCVA ≥ 24 ETDRS letters at screening and baseline of the study
* Non-study eye had not had intravitreal anti-VEGF injections for at least 3 months before baseline
