ABSTRACT: Objectives: To study the visual field changes after intravitreal ranibizumab (IVR) injection and sulfotanshinone sodium (SS) injection for macular edema (ME) secondary to retinal vein occlusion (RVO), and discuss the value of microperimetry as a routine diagnostic test in the follow-up of RVO patients. Methods: This was a retrospective, interventional, case-series study. Twelve eyes of 12 RVO patients, including 6 eyes with central RVO (CRVO) and 6 eyes with branch RVO (BRVO) were included. The eyes were treated with IVR (0.5 mg) injections and SS injections (20 mg per day, one week consecutively in one month). The outcomes measured included best corrected visual acuity (BCVA), central retinal thickness (CRT), mean defect (MD), pattern standard deviation (PSD), macular light sensitivity of the central 16 points in CRVO group and the central 8 points in BRVO group before and after the treatment. Statistical analyses were then performed on the main outcome measures. Results: An improvement of BCVA was found in all patients after treatment with significant difference (t = 7.74, p p p p > 0.05). All RVO patients had their macular light sensitivity of the involved part improved significantly (t = 5.03, p p p
