Interventions/Control_1

This is a 6 months, prospective, interventional, exploratory, consecutive case series study, and followed by 6 months extension. Patients receive ranibizumab once a month during first two months. After three consecutive monthly injection of ranibizumab, patients are classified into two groups: "Initial responder" and "Initial non-responder".
Initial responder is defined that an improvement of more than 5 letters in BCVA or a decrease of at least 20% in CRT from baseline.
1)Initial responder: After three monthly injections, ranibizumab treatment is continued until macula becomes dry (Dry means CRT=<250um). After that, the injection is continued pro re nata (PRN) regimen. (Retreatment criteria of intravitreal ranibizumab is CRT=>250um)
2)Initial non-responder: After three consecutive monthly injections, FA is performed to clarify the vascular leak from microaneurysm close to macula edema or avascular area at Month 3 visit. Patients are treated with additional focal laser to microaneurysm and avascular area in edema region by judging from FA, fundus photograph and SD-OCT at this visit, if these regions are applicable for focal laser. After focal laser, ranibizumab injection is given at this visit followed by ranibizumab injections by same manner in "initial responder". Otherwise, if focal laser is not applicable to the regions based on the examinations, patients receive ranibizumab injections by similar manner in "initial responder". Focal laser treatment is able to be performed at intervals no shorter than 3 months from the first focal laser.
Laser condition: power80-100mA, spot size 50-100um, duration 0.1second, Area Centralis/TransEquater as lens.
Fundus condition has to be estimated by FA, SD-OCT and fundus photograph during examination. If patient lose therapeutic effect during only ranibizumab therapy, focal laser have to be performed after examination.
