Drug: Ranibizumab
DME patients who were diagnosed through fundus manifestations and FFA examination were treated by intravitreal injections of ranibizumab (0.5mg Lucentis®; Genentech, South San Francisco, CA) under the pro re nata (PRN) treatment regimen. The retreatment were conducted if BCVA was reduced by 0.1 logarithm of the minimal angle of resolution (logMAR) value or more from maximum acuity or if OCT central subfield thickness was more than 300μm. |

- Central foveal thickness [ Time Frame: one year ]changes of central foveal thickness

Ages Eligible for Study: | 18 Years to 90 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
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.
