To report a case of polypoidal choroidal vasculopathy (PCV) recalcitrant to treatment with ranibizumab and with a ranibizumab port delivery system (Susvimo) but responsive to faricimab-svoa. A case and its findings were analyzed. A 69-year-old Filipino man with PCV in the left eye was treated for 2 years with multiple ranibizumab intravitreal (IVT) injections followed by ranibizumab port delivery combined with rescue ranibizumab IVT injections, with no significant response clinically or on imaging. The visual acuity (VA) worsened to 20/100 OD. IVT treatment was switched to faricimab-svoa injections. After 2 injections, there was significant improvement on optical coherence tomography and in VA (20/60). This case shows the potential therapeutic benefits of targeting angiopoietin-2 in addition to vascular endothelial growth factor to treat PCV refractory to ranibizumab. Faricimab may provide an alternative to therapy with ranibizumab and verteporfin photodynamic therapy for the treatment of PCV.

Background: We aimed to describe 1-year outcomes of eyes switched to faricimab from first-generation vascular endothelial growth factor (VEGF) inhibitors for neovascular age-related macular degeneration (nAMD) in routine care.
Methods: Multicentre, observational study of 383 eyes tracked in the Fight Retinal Blindness! registry switched to faricimab from aflibercept 2 mg, ranibizumab, or bevacizumab between 1st January-1st August 2023 in Australia.
Results: One-year completion rates were high (335/383 [88%]).

Introduction: Intravitreal injections remain the standard for treating common retinal diseases including age-related macular degeneration (AMD), diabetic macular edema (DME) and diabetic retinopathy. However, frequent administration creates significant treatment burden due to limited drug half-life and the chronic nature of these conditions.
Areas Covered: This review summarizes emerging drug delivery techniques and therapies for retinal disease that have achieved FDA approval within the past five years or have advanced to Phase 3 development, including intravitreal sustained-release platforms and alternative delivery routes (suprachoroidal, subretinal, topical, and subcutaneous).

Purpose: The purpose of this study was to report the impact of component-level changes and manufacturing process improvements on septum durability in the ocular implant of the Port Delivery Platform (PD-P), more commonly known as the Port Delivery System with ranibizumab (PDS) with its current formulation.
Methods: Laboratory tests were conducted to determine (1) the bond strength of the septum to the overmold, (2) the amount of force utilized for the refill needle to puncture the septum, and (3) septum durability over 50 years. To simulate multiple refill-exchanges over long-term clinical use, implants were aged at elevated temperature in saline and the septum was repetitively punctured at random locations using the refill needle every 3.

Importance: Frequent visits and intravitreal anti-vascular endothelial growth factor (VEGF) injections are often required to manage diabetic macular edema (DME), burdening patients and their health care networks. The Port Delivery System (PDS) with ranibizumab is the first continuous anti-VEGF therapy that has the potential to reduce visit and treatment burden without sacrificing vision outcomes for patients with DME.
Objective: To evaluate the efficacy and safety through 64 weeks of ranibizumab, 100 mg/mL, via PDS with refill exchanges every 24 weeks (PDS Q24W) in patients with DME vs intravitreal injections of ranibizumab, 0.

Importance: Frequent prophylactic intravitreal anti-vascular endothelial growth factor injections can reduce risk of progression to vision-threatening complications in nonproliferative diabetic retinopathy (NPDR). A refillable drug delivery system for continuous intraocular ranibizumab release could offer less frequent treatment regimens.
Objective: To evaluate the Port Delivery System (PDS) with ranibizumab, 100 mg/mL, with refill-exchange procedures every 36 weeks (PDS Q36W), vs no PDS (control) in moderately severe to severe NPDR without center-involved diabetic macular edema (CI-DME), monitoring both groups every 4 weeks.
