Abstract
Background and objective: To assess outcomes of visual acuity (VA) and central retinal thickness (RT) in patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO) who were initially treated with bevacizumab and followed for up to four years. Study design/Materials and methods: In this observational case series, 51 patients with non-ischemic and ischemic CRVO who had initial treatment with bevacizumab were included. Main outcome measures were VA and RT at one year, with follow-up of up to four years. Results: Mean VA improved from 20/214 at baseline to 20/107 at one year (p = 0.0009) and this improvement was maintained clinically at four years. RT decreased from 595 μm to 339 μm at one year (p = 0.0027) and this was maintained at four years. Conclusion: Patients who received bevacizumab as initial therapy for ME from CRVO maintained VA and RT improvement for up to four years.
