Retinal vasculitis after intravitreal aflibercept 8 mg for neovascular age-related macular degeneration

To evaluate short-term outcomes of intravitreal injection of aflibercept 8 mg for neovascular age-related macular degeneration (nAMD).

Retrospective, interventional case series.

We retrospectively studied 35 eyes of 34 consecutive patients with nAMD, assessing best-corrected visual acuity (BCVA), foveal thickness (FT), and central choroidal thickness (CCT) before and 4 weeks after the initial intravitreal dose of aflibercept 8 mg. The rate of achieving a dry macula and the incidence of intraocular inflammation (IOI) at week 4 were also determined.

BCVA showed significant improvement, with significant reductions in FT and CCT 4 weeks after the initial injection of aflibercept 8 mg (all P < 0.01), with a dry macula being achieved in 20 eyes (57.1%). However, 3 eyes (8.6%) developed non-infectious IOI associated with retinal vasculitis, an adverse event not reported previously. The IOI in these eyes was relatively mild and treated with a posterior subtenon injection of triamcinolone acetonide with or without betamethasone eye drops, resulting in amelioration of IOI without any visual loss.

Intravitreal aflibercept 8 mg appears to be effective for improving visual acuity and ameliorating exudative changes in eyes with nAMD. However, special attention should be given to the potential development of IOI associated with retinal vasculitis.
