Abstract
Proliferative vitreoretinopathy (PVR) remains the main cause of failure in retinal detachment (RD) surgery and a demanding challenge for vitreoretinal surgeons. Despite the large improvements in surgical techniques and a better understanding of PVR pathogenesis in the last years, satisfactory anatomical and visual outcomes have not been provided yet. For this reason, several different adjunctive pharmacological agents have been investigated in combination with surgery. In this review, we analyze the current and emerging adjunctive treatment options for the management of PVR and we discuss their possible clinical application and beneficial role in this subgroup of patients.

Abstract
INTRODUCTION Geographic atrophy (GA) is a progressive form of age-related macular degeneration (AMD) that leads to severe visual impairment and central vision loss. Traditional treatment options for GA are limited, highlighting the need for new therapeutic approaches. In recent years, targeting the complement system has emerged as a promising strategy for the treatment of GA. AREAS COVERED This expert opinion article reviews the investigational drugs inhibiting the complement cascade for the treatment of GA. Specifically, it focuses on the recent FDA approved pegcetacoplan, a C3 complement inhibitor, and avacincaptad pegol, a C5 complement inhibitor, highlighting their potential efficacy and safety profiles based on clinical trial data. EXPERT OPINION FDA approval of intravitreal pegcetacoplan and avacincaptad pegol marks significant progress in the landscape of GA treatment. However, variable results from trials underscore the complex nature of GA and the importance of patient selection. Complement inhibition holds promise, but ongoing research is vital to refine treatment strategies and offer improved outcomes for GA patients.

Abstract
OBJECTIVES (1) To assess dynamic postural stability before and after cochlear implantation using a functional gait assessment (FGA). (2) To evaluate the correlation between loss of residual hearing and changes in dynamic postural stability after cochlear implantation. METHODS Candidates for first-sided cochlear implantation were prospectively included. The FGAs and pure-tone audiograms were performed before and 4-6 weeks after cochlear implantation. RESULTS Twenty-three subjects were included. Forty-eight percent (n = 11) showed FGA performance below the age-referenced norm before surgery. One subject had a clinically relevant decrease of the FGA score after cochlear implantation. No significant difference between the mean pre- and postoperative FGA scores was detectable (p = 0.4). Postoperative hearing loss showed no correlation with a change in FGA score after surgery (r = 0.3, p = 0.3, n = 16). CONCLUSION Single-sided cochlear implantation does not adversely affect dynamic postural stability 5 weeks after surgery. Loss of functional residual hearing is not correlated with a decrease in dynamic postural stability.
