Topical azithromycin or ofloxacin for endophthalmitis prophylaxis after intravitreal injection.

Background: The number of patients who have undergone intravitreal injections has increased enormously in recent years, but a consensus is still lacking on prophylaxis for endophthalmitis. The aim of this prospective, observational study was to evaluate the prophylactic effect of azithromycin eye drops versus ofloxacin eye drops. Methods: The study was conducted in five hospitals in Spain and included all patients under going intravitreal injections of triamcinolone, bevacizumab, ranibizumab, or pegaptanib over one year. Patients received azithromycin 15 mg/g eye drops (twice daily on the day prior to injection and for another 2 days) or ofloxacin 3 mg/g eye drops (every 6 hours on the day prior to injection and for another 7 days). Results: In the azithromycin group, there were 4045 injections in 972 eyes of 701 patients. In the ofloxacin group, there were 4151 injections in 944 eyes of 682 patients. There were two cases of endophthalmitis (0.049%) in the azithromycin group and five (0.12%) in the ofloxacin group. The odds ratio of presenting with endophthalmitis in the ofloxacin group compared with the azithromycin group was 2.37 (95% confidence interval [CI] 1.32-3.72, P ,0.001). There were two cases of noninfectious uveitis after triamcinolone injection in the azithromycin group (0.049%) and two (0.048%) in the ofloxacin group; no significant differences were observed (odds ratio 0.902, 95% CI 0.622-1.407, P= 0.407). Conjunctival hyperemia was observed in 12 cases in the azithromycin group and none in the ofloxacin group. Conclusion: The risk of endophthalmitis was significantly greater with ofloxacin than with azithromycin. These findings provide a valuable addition to the ever-increasing pool of infor - mation on endophthalmitis prophylaxis after intravitreal injection, although further large-scale studies are required to provide definitive conclusions

Guía de recomendaciones para el manejo de brolucizumab

Brolucizumab; Intraocular inflammation; Patient managementBrolucizumab; Inflamación intraocular; Manejo del pacienteBrolucizumab; Inflamació intraocular; Maneig del pacientPurpose: Brolucizumab, a new generation anti-VEGF, has demonstrated efficacy and safety in AMD in the pivotal HAWK and HARRIER trials. Post-marketing, previously undetected adverse events related to intraocular inflammation have been reported. An independent post hoc review of the pivotal trials puts the rate of IOI at 4.6%. The aim of this paper is to propose a set of recommendations for implementing the management of brolucizumab in clinical practice. Methods: The recommendations made by the authors are based on their clinical experience, critical review of (i) the pivotal trials, the post-hoc analysis of the Safety Review Committee, (ii), and (iii) the published literature. Results: In the pivotal trials, brolucizumab showed sustained functional gains, superior anatomical outcomes with potentially longer intervals between injections and a well-tolerated overall safety profile. Adverse events reported post-marketing include retinal vasculitis and retinal vascular occlusion. Based on the available information, experts recommend (i) ruling out non-recommended patient profiles (prior history of ORI), (ii) screening the patient prior to each injection to rule out active ORI, (iii) monitoring the patient for early warning signs, and (iv) treating immediately should any adverse events develop. Conclusions: The adverse events reported are rare, but may be associated with severe and irreversible loss of visual acuity. The recommendations made are intended to facilitate the management of brolucizumab in the routine practice of retinologists, to ensure patient safety and, should any adverse events occur, to minimise their impact on vision.Objetivo Brolucizumab, un anti-VEGF de nueva generación, ha demostrado su eficacia y seguridad en degeneración macular asociada a la edad neovascular exudativa (DMAEn) en los ensayos pivotales HAWK y HARRIER. Tras su comercialización, se han reportado eventos adversos relacionados con la inflamación intraocular no detectados previamente. Una revision post hoc independiente de los ensayos pivotales cifra la tasa de IIO en 4,6%. El objetivo de este trabajo es proponer una serie de recomendaciones para implementar el manejo de brolucizumab en la práctica clínica. Método Las recomendaciones realizadas por los autores se han basado en su experiencia clínica y la revisión crítica de: 1) los ensayos pivotales; 2) el análisis post hoc del Comité de Revisión de Seguridad, y 3) la literatura publicada. Resultados En los ensayos pivotales, brolucizumab mostró ganancias funcionales sostenidas, resultados anatómicos superiores con intervalos entre inyecciones potencialmente más prolongados y un perfil de seguridad global bien tolerado. Los eventos adversos reportados tras la comercialización incluyen vasculitis retiniana y la oclusión vascular retiniana. De acuerdo con la información disponible, los expertos recomiendan 1) descartar los perfiles de pacientes no recomendados (historial previo de IIO), 2) explorar al paciente antes de cada inyección para descartar la presencia de IIO activa, 3) monitorizar al paciente para detectar precozmente los signos de alerta, y 4) tratar de inmediato en el caso de que se desarrolle algún evento adverso. Conclusiones Los eventos adversos reportados son poco frecuentes, pero pueden estar asociados con una pérdida severa e irreversible de agudeza visual. Las recomendaciones realizadas pretenden facilitar el manejo de brolucizumab en la práctica habitual de los retinólogos, garantizar la seguridad del paciente y, en caso de que se produzca alguno de los eventos adversos, minimizar su impacto sobre la visión

Creation of a neovascular age-related macular degeneration national database using a web-based platform: Fight Retinal Blindness Spain. Report 1: Visual outcomes

Background: To study the visual outcomes of neovascular AMD (nAMD) treated with anti-vascular endothelial growth factor (VEGF) drugs at national level. Methods: Multicenter national database of nAMD eyes treated with anti-VEGF intravitreal injections (ranibizumab, aflibercept, bevacizumab) in fixed bimonthly (FB) or treat-and-extend (TAE) regimens. Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution (logMAR) ETDRS letters at baseline and subsequent visits, number of injections and visits data were collected using a validated web-based tool (Fight Retinal Blindness!). Results: 1273 eyes (1014 patients) were included, 971 treatment naïve (TN) and 302 previously treated (PT). Baseline VA (mean ± SD) was 57.5 (±19.5) and 62.2 (±17) (p > 0.001), and 24 months final VA was 60.4 (±21.2) and 58.8 (±21.1) (p = 0.326), respectively. Mean VA change at 12/24 months was +4.2/+2.9 letters in TN eyes and +0.1/-3.4 letters in PT eyes (p < 0.001/p < 0.001). The percentage of ≥15 letters gainers/losers at 24 months was 24.8%/14.5% in TN, and 10.3%/15.7% in PT eyes. The median number of injections/visits at 12 months was 7/9 in TN and 6/8 in PT (p = 0.002/p < 0.001) and at 24 months was 11/16 in TN and 11/14 in PT (p = 0.329/p < 0.001). Study drugs included ranibizumab (39.5%), aflibercept (41.2%) and bevacizumab (19.3%). Conclusion: Independent, large-scale national audits are feasible if committed health care professionals are provided with efficient information technology systems to do them. The results described here represent an adequate measurement of the quality of care delivered nationwide and benchmark the clinical management of nAMD at a country level compared to other real-world international cohorts.

Vascular endothelial growth factor inhibitors for predominantly Caucasian myopic choroidal neovascularization: 2-year treatment outcomes in clinical practice: data from the Fight Retinal Blindness! Registry

Purpose: To report the 24-month outcomes of vascular endothelial growth factor (VEGF) inhibitors for myopic choroidal neovascularization (mCNV) in predominantly Caucasian eyes in routine clinical practice. Methods: Retrospective analysis of treatment-na¿ıve eyes starting intravitreal injection of VEGF inhibitors of either bevacizumab (1.25 mg) or ranibizumab (0.5 mg) for mCNV from 1 January 2006 to 31 May 2018 that were tracked in the Fight Retinal Blindness! registry. Results: We identified 203 eyes (bevacizumab-85 and ranibizumab-118) of 189 patients. The estimated mean (95% CI) change in VA over 24 months for all eyes using longitudinal models was +8 (5, 11) letters with a median (Q1, Q3) of 3 (2, 5) injections given mostly during the first year. The estimated mean change in VA at 24 months was similar between bevacizumab and ranibizumab [+9 (5, 13) letters for bevacizumab versus +9 (6, 13) letters for ranibizumab; p = 0.37]. Both agents were also similar in the mCNV activity outcomes, treatment frequency and visit frequency. Conclusions: The 24-month treatment outcomes of VEGF inhibitors for mCNV were favourable in this largest series yet reported of predominantly Caucasian eyes in routine clinical practice,with approximately two lines of visual gain and amedian of three injections given mostly during the first year. These outcomes are similar to those reported for predominantly Asian eyes.Bevacizumab appeared to be as safeandeffective as ranibizumab.

Dexamethasone Implant for Diabetic Macular Oedema: 1-Year Treatment Outcomes from the Fight Retinal Blindness! Registry

INTRODUCTION Phase III clinical trials of dexamethasone intravitreal implant for diabetic macular oedema (DMO) have reported significant improvements in visual acuity (VA). Studies evaluating the treatment of DMO in routine clinical practice provide data to identify areas that need improvement. This study evaluated 12-month treatment outcomes of dexamethasone implant for DMO in routine clinical practice. METHODS Retrospective data analysis of eyes that started dexamethasone implant for DMO from 1 June 2013 to 30 April 2019 in routine clinical practice tracked in the Fight Retinal Blindness! Registry. RESULTS Of the 4282 eyes (2518 patients) that started DMO treatment in the specified period, 267 (6%) eyes (204 patients) received 454 dexamethasone implant injections. Two-fifths (106 eyes) had received prior treatment for DMO. The mean (95% confidence interval [CI]) VA change at 12 months was 1.8 (- 0.5, 4.2) letters from the mean (standard deviation [SD]) VA of 56.5 (19.8) letters at baseline, with 41% eyes achieving at least 20/40. The mean (95% CI) change in central subfield thickness over 1 year was - 79 (- 104, - 54) µm from a mean (SD) of 459 (120) µm at baseline. Eyes that completed 1 year of follow-up received a median (Q1, Q3) of 2 (1, 2) dexamethasone implants. One-tenth of phakic eyes received cataract surgery while 2% had a pressure response requiring anti-glaucoma medications. CONCLUSIONS One-year treatment outcomes of dexamethasone intravitreal implant for DMO in routine clinical practice were inferior to those in the clinical trials perhaps because of fewer treatments in clinical practice

Vascular endothelial growth factor inhibitors for predominantly Caucasian myopic choroidal neovascularization: 2-year treatment outcomes in clinical practice: data from the Fight Retinal Blindness! Registry

PURPOSE To report the 24-month outcomes of vascular endothelial growth factor (VEGF) inhibitors for myopic choroidal neovascularization (mCNV) in predominantly Caucasian eyes in routine clinical practice. METHODS Retrospective analysis of treatment-naïve eyes starting intravitreal injection of VEGF inhibitors of either bevacizumab (1.25 mg) or ranibizumab (0.5 mg) for mCNV from 1 January 2006 to 31 May 2018 that were tracked in the Fight Retinal Blindness! registry. RESULTS We identified 203 eyes (bevacizumab-85 and ranibizumab-118) of 189 patients. The estimated mean (95% CI) change in VA over 24 months for all eyes using longitudinal models was +8 (5, 11) letters with a median (Q1, Q3) of 3 (2, 5) injections given mostly during the first year. The estimated mean change in VA at 24 months was similar between bevacizumab and ranibizumab [+9 (5, 13) letters for bevacizumab versus +9 (6, 13) letters for ranibizumab; p = 0.37]. Both agents were also similar in the mCNV activity outcomes, treatment frequency and visit frequency. CONCLUSIONS The 24-month treatment outcomes of VEGF inhibitors for mCNV were favourable in this largest series yet reported of predominantly Caucasian eyes in routine clinical practice, with approximately two lines of visual gain and a median of three injections given mostly during the first year. These outcomes are similar to those reported for predominantly Asian eyes. Bevacizumab appeared to be as safe and effective as ranibizumab

Single-Chain Antibody Fragment VEGF Inhibitor RTH258 for Neovascular Age-Related Macular Degeneration:A Randomized Controlled Study

PurposeTo assess the safety and efficacy of different doses of RTH258 applied as single intravitreal administration compared with ranibizumab 0.5 mg in patients with neovascular age-related macular degeneration (AMD).DesignSix-month, phase 1/2, prospective, multicenter, double-masked, randomized, ascending single-dose, active-controlled, parallel-group study.ParticipantsA total of 194 treatment-naive patients, aged ≥50 years, with primary subfoveal choroidal neovascularization secondary to AMD.MethodsPatients received a single intravitreal injection of RTH258 0.5 mg (n = 11), 3.0 mg (n = 31), 4.5 mg (n = 47), or 6.0 mg (n = 44), or ranibizumab 0.5 mg (n = 61).Main Outcome MeasuresThe primary efficacy end point was the change from baseline to month 1 in central subfield thickness (CSFT) measured by spectral-domain optical coherence tomography. The secondary efficacy end point was the duration of treatment effect measured as time from the initial injection to receipt of post-baseline therapy (PBT) guided by protocol-defined criteria. Adverse events (AEs) were recorded throughout the study.ResultsRTH258 demonstrated noninferiority compared with ranibizumab in mean change in CSFT from baseline to month 1 for the 4.5- and 6.0-mg dose groups (margin: 40 μm, 1-sided alpha 0.05). The difference in CSFT change at month 1 comparison with ranibizumab was 22.86 μm (90% confidence interval [CI], −9.28 to 54.99) and 19.40 μm (95% CI, −9.00 to 47.80) for RTH258 4.5 and 6 mg, respectively. The median time to PBT after baseline therapy was 60 and 75 days for patients in the RTH258 4.5- and 6.0-mg groups, respectively, compared with 45 days for ranibizumab. Changes in best-corrected visual acuity with RTH258 were comparable to those observed with ranibizumab. The most frequent AEs reported for the RTH258 groups were conjunctival hemorrhage, eye pain, and conjunctival hyperemia; the majority of these events were mild in intensity.ConclusionsThis first-in-human study of RTH258 demonstrated noninferiority in the change in CSFT at 1 month for the 4.5- and 6.0-mg doses compared with ranibizumab and an increase of 30 days in the median time to PBT for the 6.0-mg dose. There were no unexpected safety concerns, and the results support the continued development of RTH258 for the treatment of neovascular AMD
