To describe the visual, tomographic, and electroretinographic findings in a patient with macular edema secondary to branch retinal vein occlusion who was submitted to three consecutive intravitreal injections of ziv-aflibercept.Methods:
The patient underwent a complete ophthalmic examination, as well as optical coherence tomography and full-field electroretinography at baseline and 90 days after the first injection.Results:
The best-corrected visual acuity improved from 20/400 to 20/40, and the central retinal thickness decreased from 791 μm to 198 μm after three consecutive intravitreal injections of ziv-aflibercept. Full-field electroretinography showed an increase in cone amplitude and decrease in rod amplitude. No adverse side effects were observed after injections.Conclusion:
Intravitreal injections of ziv-aflibercept showed both effectiveness and safety in the treatment of a patient with macular edema secondary to branch retinal vein occlusion. The observed anatomic (by ophthalmic examination, optical coherence tomography) and functional (best-corrected visual acuity, full-field electroretinography) improvements and lack of serious adverse side effects demonstrates the potential of intravitreal injections of ziv-aflibercept for the treatment of macular edema secondary to branch retinal vein occlusion.
