title: Intravitreal bevacizumab for macular oedema secondary to branch retinal vein occlusion.
abstract: OBJECTIVE
  To report short-term results of intravitreal bevacizumab (IVB) injection for macular oedema (ME) associated with branch retinal vein occlusion (BRVO).
  
  
  METHODS
  Retrospective interventional case series of 12 eyes of 12 consecutive patients. IVB injections (1.25 mg/0.05 ml) were given as needed based on the presence of ME on optical coherence tomography. Changes in Snellen visual acuity (VA) and central macular thickness (CMT) were analysed using the Student's paired t-test.
  
  
  RESULTS
  At a mean follow-up of 9.8 months (range: 6-17 months), the mean number of IVB injections given was 4 (range: 1-6). No ocular or systemic side effects were noted. The differences in logMAR VA between baseline and 1 month, between baseline and 6 months, and between baseline and final follow-up were statistically significant (P<0.05). The differences in CMT between baseline and 1 month, baseline and 6 months, and between baseline and final follow-up were also statistically significant (P<0.05).
  
  
  CONCLUSIONS
  Short-term results indicate that IVB is useful in decreasing ME and improving VA in eyes with BRVO.
