Update on Retinal Drug Safety: Proceedings of the ASRS ReST Committee Webinar Part 1.

To review the first Research and Safety in Therapeutics (ReST) Committee webinar and summarize the most current recommendations regarding diagnosis and management. The ReST Committee is comprised of members of the American Society of Retina Surgeons (ASRS). At regular internal meetings, safety issue reports from the website are reviewed. A webinar series was started in 2021 to update members on multiple relevant potential safety events. Topics reviewed in the webinar included pentosan polysulfate sodium (Elmiron) maculopathy, intraocular pressure elevation reported with the aflibercept prefilled syringe (PFS), and brolucizumab-associated inflammation with occlusive retinal vasculitis. Retinal toxicity related to intraoperative medications was reviewed, including hemorrhagic occlusive retinal vasculitis after intraocular vancomycin, dilution errors with intravitreal aminoglycosides, inadvertent overdoses of cefuroxime after cataract surgery, and toxic posterior segment syndrome after dropless cataract surgery using compounded triamcinolone-moxifloxacin. Indocyanine green toxicity has been reported after its use as an adjuvant during macular hole surgery. The past decade has seen advances in retinal pharmaceuticals and drug-delivery devices. The ASRS ReST Committee collects data from its website reporting system to inform members about up-to-date pharmaceutical and device safety concerns. Recently, a webinar was used to inform members of pigmentary maculopathy associated with pentosan polysulfate sodium, safety regarding the aflibercept PFS, intraocular inflammation and occlusive retinal vasculitis secondary to brolucizumab, and retinal toxicity from intraoperative ocular medications.
