Extension Study for the Port Delivery System With Ranibizumab (Portal)

This study will evaluate the long-term safety and tolerability of the Port Delivery System with ranibizumab (PDS) (100 mg/mL) in participants with neovascular age-related macular degeneration (nAMD) who have either completed Phase II Study GX28228 (Ladder), Phase III Study GR40548 (Archway), Phase IIIb Study WR42221 (Velodrome), or completed Week 24 visit in Study WR42221 but were not eligible to be randomized in WR42221.

The Transscleral Photocoagulation sub-study (sub-study 1) will evaluate the effectiveness of using transscleral photocoagulation (TPC) with the Iridex laser system to mitigate vitreous hemorrhages secondary to the Port Delivery System with ranibizumab (PDS) implantation procedure in participants with neovascular age-related macular degeneration (nAMD). The sub-study will enroll about 55 participants.

The Re-implantation sub-study (sub-study 2) will evaluate the safety of re-implantation with the updated PDS with ranibizumab . Up to 100 participants who previously participated in the main study in the United States will be enrolled and followed for a maximum of 72 weeks post-re-implantation in the substudy.

CNV Lesion Charateristics Study Eye

* Subretinal hemorrhage that involves the center of the fovea, if the hemorrhage is greater than 0.5 disc area (1.27 mm2 ) in size at screening
* Subfoveal fibrosis or subfoveal atrophy

Either Eye

- CNV due to other causes, such as ocular histoplasmosis, trauma, or pathologic myopia

Concurrent Ocular Conditions Study Eye

* Retinal pigment epithelial tear
* Any concurrent intraocular condition (e.g., cataract, glaucoma, diabetic retinopathy, or epiretinal membrane) that would either require surgical intervention during the study to prevent or treat visual loss that might result from that condition or affect interpretation of study results

* History of vitreous hemorrhage
* History of rhegmatogenous retinal detachment
* History of rhegmatogenous retinal tears or peripheral retinal breaks within 3 months prior to the enrollment visit
