Outcome of Patients Treated by Intravitreal Injections During the COVID-19 Lockdown: An Institutional Experience.

PURPOSE: To determine the loss of follow-up ratio and reasons during the COVID-19 lockdown in patients with retinal diseases treated by anti-vascular endothelial growth factor intravitreal injections and to report the visual outcome and rate of complications of these patients 1 year after the end of the lockdown. METHODS: This is a prospective descriptive cohort study (NCT04395859) conducted at the Rothschild Foundation Hospital - Paris between April 2020 and May 2021. Patients with retinal diseases treated by repeated intravitreal anti-VEGF injections (IVI) since before October 2019 were included. They filled-out a questionnaire and were followed up during a period of 1 year. RESULTS: During the COVID-19 lockdown 198 eyes (82.5%) of 157 patients (82.6%) received their injections in a timely manner (group 1) while 42 eyes (17.5%) of 33 patients (17.4%) had their injections delayed or missed (group 2). No statistically significant difference was found between group 1 and group 2 when comparing the change of mean best corrected distance visual acuity (BCVA) between month 12 and inclusion (p = 0.6) and the rate of ocular complications. The most frequent reasons for missing scheduled injections are appointments cancellation by the hospital (12 patients, 36%), fear of virus exposure during transportation (7 patients, 21%) or at the hospital (5 patients, 15%). Eighty-four percent (130/157 patients) of patients who attended their appointment were satisfied by the protective measures used in the hospital. CONCLUSION: COVID-19 lockdown did not seem to negatively affect the 1-year outcome of patients with retinal diseases treated by anti-VEGF IVIs who missed their scheduled injections. The BCVA and rate of complications at 1 year did not differ whether patients missed their scheduled injections or not. Maintaining IVIs during lockdown periods and educating patients about the risks of missing injections are pivotal in improving prognosis of retinal diseases.

Emotional and physical experiences of people with neovascular age-related macular degeneration during the injection process in Germany: a qualitative study.

OBJECTIVES: In order to better understand the continued barriers to the provision of vascular endothelial inhibitor therapy, this study aims to investigate patients' experiences with neovascular age-related macular degeneration (nvAMD) in Germany during the injection process and how they deal with it. DESIGN AND PARTICIPANTS: This analysis is part of the qualitative arm of a wider mixed-methods study. We recruited participants all over Germany via ophthalmologists, eye clinics, general practitioners, care bases and support groups between June 2018 and December 2020 and selected a subsample of study participants with nvAMD who were either undergoing or had previously undergone vascular endothelial growth factor inhibitor therapy. We conducted narrative, semistructured, face-to-face interviews at the participants' homes, which were audio-recorded. The interviews were thematically analysed. RESULTS: Twenty-two participants were included in this analysis. Experiencing neovascular macular degeneration was dominated by the injection experience. Study participants perceived the treatment with vascular endothelial inhibitor injections as uncomfortable, and they described undergoing varying levels of anxiety during the whole injection process. After some years of receiving multiple injections, the pain and not experiencing any positive effects made participants with significant vision loss want to discontinue therapy. Furthermore, they narrated negative injection experiences in association with their interactions with medical staff and doctors. CONCLUSION: Although time in the medical setting is limited, efficient and good doctor-patient relationships seem crucial for satisfying care experiences. A respectful and humane relationship may be one key to achieving treatment adherence.

The Influence of COVID-19 on the Stability of Patients with Neovascular Age-Related Macular Degeneration with Different Treatment Regimens.

INTRODUCTION: To explore the impact of coronavirus disease 2019 (COVID-19) on the stability of patients with neovascular age-related macular degeneration (nAMD) receiving the treat and extend (T&E) or the pro re nata (PRN) treatment regimen and to identify indicators that may predict the disease stability of nAMD. METHODS: This is a retrospective study of patients with nAMD treated at the Second Affiliated Hospital of Harbin Medical University whose treatment schedule was interrupted at least once between 1 February and 31 May 2020. The demographic and clinical characteristics, including the best corrected visual acuity (BCVA), optical coherence tomography (OCT) features, subfoveal choroidal thickness (SFCT), interval between the last injection and the beginning of the pandemic, and the number of anti-vascular endothelial growth factor (VEGF) injections, were analyzed. RESULTS: A total of 209 stable patients with nAMD (122 eyes received the T&E regimen; 87 eyes received the PRN regimen) were identified. Compared to those who received the PRN regimen, the patients who received the T&E regimen were more stable during the first visit after COVID-19 (53.3% vs. 33.3%, P = 0.004), the BCVA was significantly better (58.5 letters vs. 56 letters, P = 0.006), and the CRT fluctuated only slightly (15 µm vs. 35 µm, P = 0.001). Furthermore, a multivariate logistic regression analysis showed that stable patients with nAMD with type 1 choroidal neovascularization (CNV) (OR 2.493 [95% CI 1.179-5.272], compared with type 2 CNV; P = 0.017; OR 2.912 [95% CI 1.133-7.485], compared with retinal angiomatous proliferation; P = 0.026) or with pigment epithelial detachment (PED) were more likely to remain stable when treatment was interrupted (OR 0.392 [95% CI 0.181-0.852], compared with no PED; P = 0.018). CONCLUSION: Compared to patients who received the PRN treatment regimen, stable patients with nAMD who received the T&E treatment regimen could better maintain stability when the treatments were suddenly interrupted by the COVID-19 pandemic. In addition, patients with type 1 CNV or patients with PED were more likely to remain stable. At present, the COVID-19 pandemic is becoming increasingly normalized, and the T&E regimen can become a more advanced treatment option for patients undergoing therapy.

Extended intervals for wet AMD patients with high retreatment needs: informing the risk during COVID-19, data from real-world evidence.

BACKGROUND/OBJECTIVE: Some clinicians may be forced to temporarily extend treatment intervals in neovascular age-related macular degeneration (nAMD) eyes with frequent retreatments to reduce the number of visits during the COVID-19 pandemic. To provide an indication of what these outcomes may be, we studied eyes with active lesions with unplanned treatment interval extensions before the pandemic occurred. METHODS: We compared eyes with active disease despite ≤6 weekly injections whose next injection was extended to ≥7 weeks and those whose intervals were not extended. We identified 1559 (16%) of 9602 eyes from the Fight Retinal Blindness! (FRB!) registry (2013 and 2018) that fit this criteria. Eyes were further stratified into four groups by the mean interval over the following 6 months: (1) ≤6 weeks (81%), (2) 7-9 weeks (9%), (3) 10-12 weeks (5%) and (4) >12 weeks (5%). RESULTS: There was a significant loss in VA in eyes extended to >12 weeks compared to the non-extended group (adjusted VA change, mean (95% CI): ≤6 weeks, 0.4 (-1.5 to 2.2), versus >12 weeks, -4.7 (-7.4 to -2.1), letters, p = 0.03 and a threefold increase in relative risk of losing ≥15 letters (absolute risk (14% versus 4%, p < 0.01)). CONCLUSION: Mean VA remained stable for 6 months in eyes requiring frequent treatment despite retreatment interval extension up to 10-12 weeks. There was a significant short-term risk to vision when retreatment interval was extended beyond 12 weeks, hence extensions to this level should be considered cautiously. These data may be useful for physicians who are considering reducing visits to mitigate the risk of COVID-19.
