Changes in Macular Pigment Optical Density after Intravitreal Faricimab in Neovascular Age-Related Macular...

Background: This study aimed to evaluate the effects of faricimab intravitreal injections in patients with exudative age macular degeneration (nAMD) after the loading dose using spectral domain optical coherence tomography (SD-OCT) and macular pigment optical density (MPOD). Methods: In this observational prospective study, we enlisted a total of 12 consecutive eyes of 12 patients (six females, six males; mean age 70.47 ± 2.46 years) affected by nAMD who consecutively presented to the Eye Clinic of the University of Naples "Federico II" and Monaldi Hospital of Naples, from June 2023 to December 2023. All patients received four once-monthly intravitreal injections of faricimab (6 mg/0.05 mL) (loading phase). At baseline and 1 month after the fourth faricimab monthly injection, all patients underwent assessment of best correct visual acuity (BCVA) and ophthalmic examination, including slit-lamp biomicroscopy, intraocular pressure (IOP), fundus biomicroscopy, SD-OCT, and MPOD. Results: A total of 12 eyes of 12 patients (six women, six men; mean age 70.47 ± 2.46 years) were included in this study. A statistically significant raise in BCVA and MOPD parameters was shown between baseline and after the loading phase (p < 0.001). Conclusions: Intravitreal injections of faricimab led in the short term to a significant functional and MPOD improvement along with a decrease in central macular thickness (CMT) and thus appears to be an effective treatment option without relevant adverse effects. MOPD may be considered as a prognostic factor associated with a good visual prognosis after intravitreal injections treatment.
