An Uncommon Aflibercept Side Effect: Full Thickness Macular Hole Formation After Intravitreal Injections in Patients...

Aflibercept is an intravitreally injected anti-vascular endothelial growth factor, commonly used in patients with several retinal pathologies, including neovascular age-related macular degeneration. We report a case series of three patients under treatment with an aflibercept regime for neovascular age-related macular degeneration, who were referred to vitreoretinal service between 2015-2016. In all cases, pre-existing vitreomacular traction was detected with an optical coherence tomography scan. All of them developed full-thickness macular hole after aflibercept intravitreal injections. The combined cataract and macular hole surgery was successful, with improvement in visual acuity. We suggest that dynamic alterations of the size of the pigment epithelium detachment resulting from intravitreal injections might intensify the pre-existing pathological adhesion of the vitreous-retinal interface and subsequently cause the formation of a full-thickness macular hole. Therefore, all practitioners treating patients with aflibercept intravitreal injections and pre-existing vitreomacular traction should be aware of the possible macular hole formation.
