Geographic atrophy (GA) is a form of advanced age-related macular degeneration (AMD) affecting approximately 1 million people in the USA and 5 million globally. In this review, retinal imaging techniques used for diagnosis and monitoring progression of GA in AMD, and the risk factors associated with the development and progression of GA are summarised. To familiarise clinicians with common phenotypes of patients with GA, the clinical and imaging features that may lead to rapid progression of GA in various phenotypes are highlighted. With the recent US Food and Drug Administration approval of new GA treatments that reduce lesion growth, understanding the risk of progression to GA and factors contributing to GA growth may aid in patient selection and guide patient-level management and treatment.

Purpose: To review the first Research and Safety in Therapeutics (ReST) Committee webinar and summarize the most current recommendations regarding diagnosis and management. Methods: 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. Results: 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. Conclusions: 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.

Syringes containing anti-vascular endothelial growth factor drugs to treat retinal diseases are prepared in different ways by various parties with syringe selection, preparation, and storage conditions affecting the risk of injecting particles into the vitreous. This study examines particle loads from various syringes over time. Four syringes were studied: two plastic transfer syringes lubricated with silicone oil or oleamide, a glass syringe with baked-on silicone, and a lubricant-free polymer syringe. Syringes were rinsed with water or filled with buffer and analyzed over time; particles were quantified by flow imaging. Particle formation in a bevacizumab formulation was also characterized. Insulin syringes consistently showed very high particle counts. Oleamide-lubricated syringes had substantially fewer particles, but showed appreciable increases over time (leading to visible particles). Baked-on silicone glass syringes and lubricant-free polymer syringes both showed low particle levels ≥10 μm. Lubricant-free syringes showed the lowest particle levels ≥1 μm and the lowest particle levels with bevacizumab agitation. Syringes have different intrinsic particle loads which can contribute to particle loads in the delivered drug. Oleamide-lubricated transfer syringes, commonly used for bevacizumab repackaging, have time-dependent particle loads and are associated with the formation of visible particles beyond 30 days of storage.

To assess the risk of lung cancer associated with occupations and industries. A French population-based case-control study included 2923 cases and 3555 controls. Lifelong occupational history was collected. Two lists of occupations known (A) or suspected (B) to be associated with lung cancer were used. Occupations and industries not included in these lists were also explored. Among men, the smoking-adjusted odds ratio was 1.97 for list A (attributable fraction: 12.3%), 1.4 for list B (due especially to carpenters/joiners and transport workers). Among unlisted occupations, excess risks were found for welders, plumbers, and several construction crafts. Odds ratios among women were elevated for list A, list B (due especially to launderers/dry cleaners), cleaners and hairdressers. These results confirm the role of known occupations and give insight into new occupational risk factors among men and women.
