Abstract

OBJECTIVE : To assess the efficacy of intravitreal aflibercept in patients suffering from post-radiation macular edema following plaque radiotherapy for choroidal melanoma.
METHODS : This prospective, interventional case series included patients affected by radiation maculopathy (RM) with macular edema secondary to ruthenium-106 plaque brachytherapy for choroidal melanoma. The effect of intravitreal aflibercept on best-corrected visual acuity (BCVA), central foveal thickness (CFT) detected by spectral domain optical coherence tomography (sd-OCT), and Horgan's grading scale of RM was evaluated throughout the 24-month follow-up. Intraocular pressure (IOP) and possible complications were also recorded.
RESULTS : Nine eyes of 9 patients were included. A mean of 4.4 ± 1.2 injections were given over the 24 months. At the end of follow-up, mean BCVA was significantly improved, from 0.9 ± 0.19 logMAR at baseline to 0.56 ± 0.3 logMAR (P = 0.028), and mean CFT was significantly decreased, from 546 ± 123 μm at baseline to 223 ± 34 μm (P < 0.001). Intravitreal aflibercept lowered baseline maculopathy stage as well. No significant change in IOP values and no complications, such as endophthalmitis, was recorded.
CONCLUSIONS : Intravitreal aflibercept is an effective treatment for patients with radiation-induced macular edema, allowing functional and anatomical improvements to be achieved with a relatively low number of injections.
