Efficacy and safety of brolucizumab for serous drusenoid pigment epithelium detachment non-responder to bevacizumab and aflibercept.

ABSTRACT

INTRODUCTION: We report the case of a woman with drusenoid pigment epithelial detachment (DPED) in age-related macular degeneration who was successfully treated with two monthly intravitreal injections of brolucizumab after failing to respond to previous intravitreal injections of bevacizumab and aflibercept. CASE DESCRIPTION A 56-year-old woman with mixed DPED and overlying subretinal fluid in her right eye was initially treated with three intravitreal injections of bevacizumab and three intravitreal injections of aflibercept with no visual and anatomical improvement. Switching to intravitreal injection of brolucizumab was performed. After two consecutive monthly intravitreal injections of brolucizumab, optical coherence tomography (OCT) showed first subretinal fluid resolution and then DPED collapse in the following months. After nine months, the best corrected visual acuity had improved from 20/40 to 20/20. There were no signs of retinal atrophy and exudative activity on OCT examination. No serious or minor adverse events were reported during the follow-up period. CONCLUSIONS: Switching to intravitreal brolucizumab injection might be an effective therapeutic option for treatment of mixed DPED with subretinal fluid refractory to other anti-VEGF drugs.
