Brief Summary
Title of study: Effects of Ranibizumab to delay or regression non-proliferative diabetic retinopathy(NPDR) with DME assessed by microaneurysm changes: A pilot study Objectives Diabetic retinopathy (DR) is a major cause of visual impairment. Anti-vascular endothelial growth factors have demonstrated therapeutic benefits in diabetic macular edema (DME). We aimed to prospectively analyze the effects of early intensive treatment using intravitreal ranibizumab (IVR) injections in nonproliferative diabetic retinopathy patients with macular edema. Primary objective: To investigate other efficacy endpoints including other visual acuity, anatomical change in mild-to-moderate NPDR with DME after intravitreal Ranibizumab injection from baseline through 6 months after treatment. Secondary objectives: To compare microvascular changes assessed by microaneurysm counts and perifoveal non-perfusion area changes and safty in eyes of mild-to-moderate NPDR with DME after intravitreal Ranibizumab injection from baseline through 6 months after treatment.

Outcome Measures
Primary Outcomes (2)
The Best Corrected Visual Acuity (BCVA)
BCVA was performed using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at baseline and 6 months. The BCVA compare the degree of improvement or worsening of vision at baseline and 6 months. (value at 6 months minus value at baseline)
6 months
Central Macular Thickness(CMT)
CRT was performed using OCT at each visit. The OCT measured at each visit was analyzed statistically. the CMT compare the degree of improvement or worsening of vision at baseline and 6 months. (value at 6 months minus value at baseline)
6 months
Secondary Outcomes (6)
The Total Number of Microaneurysm
6 months
The Microaneurysm Formation Rate
6 months
The Microaneurysm Disappearance Rate
6 months
The Microaneurysm Turnover
6 months
Perifoveal Non-perfusion Area in FAG (mm²)

Study Arms (1)
Lucentis
EXPERIMENTALPatients were administered 0.5-mg IVR injections monthly for 6 months.
Interventions
Local anesthesia with T-caine with Saline irrigation. Routine eye drap was done by potadine-cotton ball. Lucentis injected to vitreous cavity, finally dressing.
