Purpose: To review sustained-release intraocular platforms used to treat diseases of the retina and choroid. Methods: A literature review of the current applications of biomaterials for sustained-release therapy in retinal and choroidal diseases was performed. Results: Retinal and choroidal diseases, such as neovascular age-related macular degeneration (nAMD), diabetic retinopathy (DR), diabetic macular edema (DME), and uveitis, are commonly treated using intravitreal (IVT) therapies that require frequent IVT injections. Multiple sustained-release options for IVT therapy have been approved by the US Food and Drug Administration for the treatment of inflammatory eye diseases, including noninfectious uveitis, infectious diseases, and exudative retinal diseases (eg, retinal venous occlusive disease and DME) using drugs such as fluocinolone acetonide, ganciclovir, and dexamethasone. The platforms for these drugs are biodegradable or nonbiodegradable. They use biomaterials such as polymers and hydrogels and are typically implanted surgically or injected into the vitreous, where they release the drug gradually over months or years. Building on these technologies, novel platforms are being studied that are intended to treat conditions including nAMD, DR, DME, and uveitis. These platforms are being tested for their safety, efficacy, and ability to reduce the injection and visit burden. Conclusions: Multiple sustained-release ocular drug-delivery platforms are currently commercially available, and many new sustained-release IVT platforms are being investigated. The hope is that meaningfully reducing the injection burden by extending intervals between treatments while maintaining optimal efficacy will improve long-term outcomes., Competing Interests: Dr. Wykoff: Consulting—4DMT, AbbVie, Adverum, Aerie, AGTC, Alcon, Annexon, Apellis, Arrowhead, Ascidian, Bayer, Bausch+ Lomb, Boehringer Ingelheim, Cholgene, Clearside, Curacle, Eyebiotech, EyePoint, Foresite, Frontera, Genentech, Gyroscope, Iveric Bio, Janssen, Kato, Kiora, Kodiak, Kriya, Merck, Nanoscope, Neurotech, NGM, Notal Vision, Novartis, Ocular Therapeutix, Ocuphire, OcuTerra, ONL, Opthea, Oxular, Palatin, PerceiveBio, Perfuse, Ray, RecensMedical, Regeneron, RegenxBio, Resonance, Roche, Sanofi, SciNeuro, Stealth, Surrozen, Suzhou Raymon, THEA, TissueGen, Valo.

Purpose: To report a case of a suspected open-globe injury and globe penetration complicated by a rhegmatogenous retinal detachment (RRD) after administration of intraoral anesthetic injections during an endodontic procedure. Methods: A retrospective chart review was performed. Results: A 34-year-old woman presented with acute onset of flashes, floaters, and a curtain-like shadow across her field of vision. Four days previously, she had multiple left-sided anesthetic injections during an endodontic procedure. The visual acuity (VA) in the left eye was 20/25. Ophthalmoscopy showed a suspected globe-penetration site inferiorly, associated multilayered hemorrhages, and adjacent subretinal fluid. Laser demarcation of the inferior RRD was performed at sequential clinical visits. Through 8 months, the multilayered hemorrhages improved while proliferative vitreoretinopathy-associated tissue formation over the posterior pole caused macular distortion and mild visual deterioration. The VA in the left eye was 20/40 at the last follow-up. Conclusions : Iatrogenic globe penetration during intraoral anesthesia delivery associated with an endodontic procedure may result in globe injury., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Purpose: To evaluate clinical trials in the literature that focus on suprachoroidal drug delivery for the treatment of noninfectious uveitis and other posterior segment diseases. Methods: A synthesis of the literature was performed. Results: In 2021, suprachoroidal space triamcinolone acetonide, a corticosteroid delivery system used for the treatment of uveitic macular edema (ME), was approved by the US Food and Drug Administration. The drug-delivery system targets the suprachoroidal space using a microneedle-based device and has a favorable pharmacokinetic profile. Suprachoroidally administered investigational therapies have also been assessed in clinical trials for other posterior segment diseases, including diabetic ME, retinal vein occlusion, age-related macular degeneration, and choroidal melanoma. Conclusions: The safety and efficacy of suprachoroidal corticosteroid injections to treat uveitic ME have been shown in recent phase III clinical trials. Multiple programs are also investigating this modality of drug delivery for use in many other retinal and choroidal pathologies., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr. Yeh reports consulting and advisory board fees from Bausch + Lomb, Clearside Biomedical, Inc, and RegenxBio.

Purpose: Advancements in retinal imaging have augmented our understanding of the pathology and structure-function relationships of retinal disease. No single diagnostic test is sufficient; rather, diagnostic and management strategies increasingly involve the synthesis of multiple imaging modalities. Methods: This literature review and editorial offer practical clinical guidelines for how the retina specialist can use multimodal imaging to manage retinal conditions. Results: Various imaging modalities offer information on different aspects of retinal structure and function. For example, optical coherence tomography (OCT) and B-scan ultrasonography can provide insights into the microstructural anatomy; fluorescein angiography (FA), indocyanine green angiography (ICGA), and OCT angiography (OCTA) can reveal vascular integrity and perfusion status; and near-infrared reflectance and fundus autofluorescence (FAF) can characterize molecular components within tissues. Managing retinal vascular diseases often includes fundus photography, OCT, OCTA, and FA to evaluate for macular edema, retinal ischemia, and the secondary complications of neovascularization (NV). OCT and FAF play a key role in diagnosing and treating maculopathies. FA, OCTA, and ICGA can help identify macular NV, posterior uveitis, and choroidal venous insufficiency, which guides treatment strategies. Finally, OCT and B-scan ultrasonography can help with preoperative planning and prognostication in vitreoretinal surgical conditions. Conclusions: Today, the retina specialist has access to numerous retinal imaging modalities that can augment the clinical examination to help diagnose and manage retinal conditions. Understanding the capabilities and limitations of each modality is critical to maximizing its clinical utility., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr. Berrocal has financial interests in Aerie Pharmaceuticals, ProQR therapeutics, Oculus Surgical, Alcon, Allergan, Bayer, DORC, Phoenix Clinical, Vizunex Medical Systems, Zeiss, and Novartis.

Purpose: To compare rates of endophthalmitis (1) following intravitreal injection of antivascular endothelial growth factor therapies with glass-vial preparation (GVP) vs prefilled syringes (PFS) and (2) before and after masking protocols were implemented. Methods: Medical records within a multicenter retina practice in Houston, Texas, from January 2015 to August 2021 were retrospectively reviewed. The primary outcome was rate of endophthalmitis after intravitreal injection. Results: A total of 307 349 injections were performed during the study period and 101 cases of endophthalmitis were identified (0.033%). PFS use was associated with a decreased risk of endophthalmitis (relative risk [RR], 0.320; 95% CI, 0.198-0.518, P  < .001); 54 cases of endophthalmitis occurred in the GVP group of aflibercept and ranibizumab (0.052%) compared with 24 in the PFS group (0.017%). There was no difference in the endophthalmitis rates with or without universal masking (RR, 0.953; 95% CI 0.616-1.473, P  = .91). Discussion: PFS use was associated with a significant reduction in the rate of endophthalmitis while the use of surgical face masks did not appear to significantly impact the rate of endophthalmitis., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: CCW declares the following conflicts of interest: Consulting fees/honoraria for ongoing services provided as a Consultant for: 4DMT, AbbVie, Adverum, Aerie, AGTC, Alcon, Annexon, Apellis, Arrowhead, Bausch + Lomb, Boehringer Ingelheim, Cholgene, Clearside, Curacle, EyePoint, Foresite, Frontera, Genentech, IVERIC Bio, Janssen, Kato, Kiora, Kodiak, Kriya, Merck, Nanoscope, NGM, Notal Vision, Novartis, Ocular Therapeutix, OcuTerra, ONL, Opthea, Oxular, Palatin, PerceiveBio, Perfuse, Ray, RecensMedical, Regeneron, RegenXBio, Resonance, Roche, SciNeuro, Stealth, Surrozen, Suzhou Raymon, THEA, TissueGen, Valo Grants paid to my institution for ongoing research support as a Principal Investigator for trials sponsored by: 4DMT, Adverum, AffaMed, Alexion, Alimera, Alkahest, Allgenesis, Amgen, Annexin, Annexon, Apellis, Asclepix, Bayer, Boehringer Ingelheim, Chengdu Kanghong, Clearside, Curacle, EyePoint, Gemini, Genentech, GlaxoSmithKline, Gyroscope, IONIS, iRENIX, IVERIC bio, Kodiak, LMRI, Nanoscope, Neurotech, NGM, Novartis, Ocular Therapeutix, Ocuphire, OcuTerra, Ophthotech, Opthea, Oxurion, Oxular, Oyster Point, PerceiveBio, Regeneron, RegenXBio, Roche, SamChunDang Pharm, Sandoz, UNITY, Verily, Xbrane Stock Options (not owner) from ongoing relationships as a Consultant from Private For-Profit Entities: ONL, PolyPhotonix, RecensMedical, TissueGen, Visgenx, Vitranu The remaining authors declare that there are no conflicts of interest., (© The Author(s) 2023.)

Purpose: To detail the rationale behind recommendations recently published by the American Society of Retina Specialists (ASRS) outlining best practices for safety of vitreoretinal surgeons and staff while performing vitreoretinal surgery during the coronavirus disease (COVID)-19 pandemic., Methods: The committee for ASRS Best Practices for Retinal Surgery during the COVID-19 Pandemic reviewed existing evidence and information on SARS-CoV-2 transmission, and risk factors during vitreoretinal surgery. Recommendations were based on best available published data, cumulative clinical experiences, and recommendations and policies from other organizations. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the strength of recommendations and confidence in the evidence. These serve as interim recommendations which are routinely updated given gaps of knowledge and lack of high-quality data on this evolving subject., Results: Relevant existing literature related to methods of transmission, and ocular manifestations of SARS-CoV-2 are summarized. The data and clinical experiences driving recommendations for pre-operative, intraoperative and post-operative surgical considerations, anesthesia choice, as well as considerations for intravitreal injections are provided., Conclusion: Recommendations are provided with the goal of protecting vitreoretinal surgeons and associated personnel from exposure to SARS-CoV-2 during interventional vitreoretinal procedures. This is a rapidly evolving topic with numerous remaining gaps in our current knowledge. As such, recommendations will evolve and the current manuscript is intended to serve as a foundation for continued dialogue on best practices., Competing Interests: Conflicts of Interests: J.S., C.C.W, Y.Y, A.M.B., T.M. are consultants for Alcon. A.E.K. is a consultant for Bausch and Lomb.

Purpose: Nonproliferative (NPDR) and proliferative diabetic retinopathy (PDR) without diabetic macular edema (DME) affect millions of individuals living with diabetes throughout the world. There is increasing data on various management strategies for such patients, but there is limited consensus on how the data should be adopted into clinical practice., Methods: This literature review and editorial presents and synthesizes the current evidence for various management paradigms for NPDR and PDR without DME., Results: Retina specialists are an integral member of the diabetes management team, and should encourage patients on the importance of glycemic and cardiovascular optimization for both systemic and retinopathy risk factor reduction. The diabetic retinopathy severity scale (DRSS) is now an approvable endpoint for clinical trials in the United States, therefore becoming more clinically relevant. For PDR without DME, the Diabetic Retinopathy Study (DRS) and the Early Treatment Diabetic Retinopathy Study (ETDRS) established the standard of care with panretinal photocoagulation (PRP). Laser parameters have since evolved to include less intense and earlier intervention. Studies have recently demonstrated that anti-vascular endothelial growth factor (VEGF) treatment of PDR is effective at regressing neovascularization and improving DRSS levels in many patients. Further evidence is required to determine optimal treatment frequency, duration, and retreatment criteria, in the real world. There are concerns for adverse events in patients being lost to follow up during anti-VEGF treatment. For NPDR without DME, the standard of care has been a wait-and-watch approach. Data within the DRS and the ETDRS suggest that PRP for severe NPDR can be an option for select patients as well. Multiple clinical trials have now demonstrated that anti-VEGF treatment can improve the DRSS score in NPDR. Further studies are required to assess whether this positively affects long-term visual outcomes, and whether the benefits outweigh the risks in the real world for routine use., Conclusions: There is cumulative evidence demonstrating the efficacy of various treatment options for NPDR and PDR without DME. Currently, patients would most likely benefit from thoughtful management strategies that are tailored to the individual patient.
