Effects on the contralateral eye after intravitreal bevacizumab and ranibizumab injections: a case report
1Doheny Retina Institute, Doheny Eye Institute, Los Angeles, CA 90033, USA.
Introduction:
We report a case in which intravitreal bevacizumab and ranibizumab appeared to have effects in the contralateral, uninjected eye.
Clinical Picture:
An 83-year-old man with macular oedema from branch retinal vein occlusion (BRVO) in the right eye developed neovascular macular degeneration in the left eye. Intravitreal bevacizumab in the left eye improved macular oedema in the right eye temporarily before it recurred. Subsequently, intravitreal ranibizumab in the left eye also resulted in significant reduction of macular oedema in the right eye.
Outcome:
Vision and macular oedema in the right eye improved.
Conclusion:
Bevacizumab and ranibizumab may have therapeutic effects in the uninjected eye, possibly because they may escape from the eye into the systemic circulation.
