ABSTRACT

RATIONALE: In this paper, we report on 2 patients who developed branch retinal vein occlusion (BRVO) exacerbation 1 day after administration of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine. PATIENT CONCERNS: Case 1: A 71 year-old female developed vision loss in her left eye 1 day after receiving a second dose of the SARS-CoV-2 mRNA vaccine. This patient was diagnosed with temporal inferior BRVO and secondary macular edema (ME) in her left eye. ME resolved after 3 doses of intravitreal aflibercept (IVA). After treatment, no recurrence of ME was observed.Case 2: A 72 year-old man developed vision loss in his right eye 1 day after receiving the first dose of the SARS-CoV-2 mRNA vaccine. This patient was diagnosed with temporal superior BRVO in the right eye without ME. The patient was followed up and did not undergo any additional treatment. DIAGNOSES: Case1: Temporal superior BRVO and secondary ME were observed in the left eye. Her best-corrected visual acuity (BCVA) was 20/30.Case2: Temporal superior BRVO recurrence and secondary ME were observed in the right eye. BCVA was 20/25. INTERVENTIONS: Case1: Additional dose of IVA was administered. Case2: Two times of Intravitreal ranibizumab was administered twice. OUTCOMES: Case1: Subsequently, ME resolved BCVA was 20/20. Case2: Subsequently, ME resolved BCVA was 20/25. LESSONS: Both cases showed a possible association between SARS-CoV-2 vaccination and the exacerbation of BRVO.

ABSTRACT

PURPOSE: To describe our managing strategy for COVID-19 emergency, to evaluate the adherence to intravitreal treatment (AtT) rate during the outbreak in a referral hospital in Milan, and to correlate it with patients' clinical features. METHODS: The AtT rate of patients with scheduled intravitreal injections during the COVID-19 outbreak from February 23, 2020 to March 31, 2020 was compared with the previous trimester and with March 2019. The impact of age, sex, visual function, and diagnosis on the AtT rate during unlocked/locked weeks (from March 8th) was evaluated. RESULTS: Of 650 consecutive patients with scheduled intravitreal injections, the AtT rate during the COVID-19 outbreak was 0.37. This was significantly lower compared with AtT registered in the previous trimester (0.92) and in the same weeks in 2019 (0.90) (both P < 0.001). Patients adherent to treatment were significantly younger (P < 0.001) and had a lower best-corrected visual acuity in the fellow eye (P = 0.046). During the lockdown weeks, the AtT rate was significantly lower than in the two unlocked weeks (0.19 vs. 0.73, P < 0.001). In addition, the AtT rate in patients classified as "emergent" during the lockdown weeks was 0.60. CONCLUSION: These preliminary results can help the retina specialist community to foresee this unique scenario and to develop successful management strategies.

ABSTRACT

PURPOSE: To assess functional and anatomical consequences of the delay in intravitreal injections for diabetic macular edema (DME) patients during the corona virus pandemic lockdown in Morocco as well as to evaluate factors associated with disease progression. PATIENTS AND METHODS: This cross-sectional study included DME patients who did not complete their scheduled intravitreal bevacizumab injections during the Lockdown period (March 20, 2020 to May 20, 2020). Data recorded included age, duration of diabetes, number of previous intravitreal injections, best-corrected visual acuity, and central macular thickness before and after the lockdown. RESULTS: One hundred and fifty four eyes of 104 patients were analyzed. 57.8% were male. The mean age was 59.4±9.04 years. The mean duration of delay of intravitreal injections was 57.3±6.7 days. The mean number of intravitreal bevacizumab injections received before the lockdown was 2.29±2.1. Worsening of visual acuity was noted in 44.8% of patients and was associated with a lower number of intravitreal injections performed prior to the lockdown (P=0.001) and with glycemic imbalance (P=0.04). An increase in central macular thickness was noted in 26.6% of patients and was associated with a lower number of intravitreal injections (P=0.038). CONCLUSION: The delay in intravitreal injections during the lockdown had negative effects on visual acuity and central macular thickness in eyes with DME. Prolonged delay in intravitreal anti-VEGF injections in diabetic patients should be avoided.

ABSTRACT

PURPOSE: To assess the clinical status of treatment-naive patients who had to delay 3-dose loading anti-VEGF (anti-vascular endothelial growth factor) injections during the COVID-19 lockdown, and to evaluate the effect of the delayed visual acuity treatment on spectral domain optical coherence tomography (SD-OCT) parameters. METHOD: A total of 55 eyes of 46 patients who were received in the study period participated in this retrospective study, including 28 patients (37 eyes) with diabetic macular edema (DME), 11 patients (11 eyes) with retinal vein occlusion (RVO), and 7 patients (7 eyes) with wet age-related macular degeneration (wet-AMD). The patients were diagnosed with DME, RVO, or wet-AMD in February 2020 and had planned 3-dose loading injections in March, April, and May 2020, but could not be injected due to the COVID-19 pandemic. RESULTS: From the patients' initial examination in February 2020, the mean best corrected visual acuity (BCVA) was 0.72 ± 59 logMAR. After the patients' lockdown visit in July 2020, the mean BCVA was 0.76 ± 64 logMAR. BCVA was stable in 11 eyes, decreased in 12 eyes, and increased in 14 eyes for patients with DME. BCVA was stable in 6, decreased in 3, and increased in 2 eyes for patients with RVO, and it was stable in 4 eyes and decreased in 3 eyes for patients with wet-AMD. CONCLUSION: We concluded that 6-month delay in treatment of DME patients with non-proliferative DRP had no adverse effect on the visual acuity. However, the loading dose in wet-AMD and RVO patients should be applied as soon as possible.

ABSTRACT

OBJECTIVE: Management of age-related macular degeneration (AMD) places a high demand on already constrained hospital-based eye services. This study aims to assess the safety and quality of follow-up within the community led by suitably trained non-medical practitioners for the management of quiescent neovascular AMD (QnAMD). METHODS/DESIGN: This is a prospective, multisite, randomised clinical trial. 742 participants with QnAMD will be recruited and randomised to either continue hospital-based secondary care or to receive follow-up within a community setting. Participants in both groups will be monitored for disease reactivation over the course of 12 months and referred for treatment as necessary. Outcomes measures will assess the non-inferiority of primary care follow-up accounting for accuracy of the identification of disease reactivation, patient loss to follow-up and accrued costs and the budget impact to the National Health Service. ETHICS AND DISSEMINATION: Research ethics approval was obtained from the London Bloomsbury Ethics Committee. The results of this study will be disseminated through academic peer-reviewed publications, conferences and collaborations with eye charities to insure the findings reach the appropriate patient populations. TRIAL REGISTRATION NUMBER: NCT03893474.

ABSTRACT

PURPOSE: The coronavirus pandemic has prompted unprecedented delays to treatment with anti-VEGF intravitreal injections due to the need to reduce hospital attendances and prioritise the patients at highest risk of vision loss. This study aims to quantify the effect of these delays on visual acuity (VA) outcomes and optical coherence tomography (OCT) features for patients receiving treatment for neovascular age-related macular degeneration (nAMD), retinal vein occlusions (RVO) and diabetic macular oedema (DMO) and correlate to the Royal College of Ophthalmologists guidelines (RCOphth). METHODS: A retrospective data analysis of an electronic medical record was performed on a random sample of eyes receiving anti-VEGF injections for nAMD, RVO or DMO. Data collected included age, sex, reason for injection, number of weeks delay if > 8 weeks from that planned, VA at baseline and follow-up and the OCT features, if delayed. For those eyes not delayed, a visual acuity at 20 weeks was recorded to provide a control group. RESULTS: A sample of 981 eyes (858 patients) were analysed. There was a delay in review of 8 weeks or more in 39.6% of patients of which 30.4% had since returned for review (28.4% nAMD, 37.6% RVO and 30.0% DMO). There was no demographic difference identified between the delayed and non-delayed patients; however, the delayed group was significantly more likely to have better vision in their non-treated eye (p = 0.0003). A statistically significant difference was found in the change in VA between the delayed and the not-delayed group for eyes with nAMD (p = 0.001) but not for RVO or DMO. For the delayed group, mean CMT increased by 33 and 100 µm, respectively, for nAMD and RVO and decreased by 7.8 µm for DMO. The VA of 89.7% of DMO eyes returned to baseline, compared to 74.6% and 76.9% of nAMD and RVO eyes. CONCLUSION: The RCOphth guidance to prioritise intravitreal injections for nAMD over DMO appears appropriate in this cohort but not for RVO. Eyes with nAMD experienced the greatest loss of vision with treatment delay, and nAMD and RVO eyes were less likely to return to baseline on restarting treatment.

ABSTRACT

PURPOSE: To evaluate the rates of postintravitreal injection-related endophthalmitis during the COVID-19 pandemic with institution of both physician and patient face masking. METHODS: All eyes receiving intravitreal injections of any kind from a single large tertiary retina practice in Houston, TX before (August 2017-March 22, 2020) and after (March 23, 2020-September 2020) COVID-19 pandemic universal masking protocols. The total number of injections and cases of acute injection-related endophthalmitis were determined from billing records and subsequent retrospective chart review. The primary outcome was the rate of endophthalmitis after intravitreal injection. Secondary outcomes included visual acuity, time until initial presentation, patient age, and differences in the overall number of injections performed monthly pre-COVID-19 and post-COVID-19. RESULTS: A total of 134, 097 intravitreal injections were performed during the study period (111,679 pre-COVID-19 and 22,418 post-COVID-19 masking protocols). A total of 41 cases of acute endophthalmitis occurred in the pre-COVID group (0.04%, one in 2,500) and 7 cases in the post-COVID group (0.03%, one in 3,333) P = 0.85. CONCLUSION: In this single center, retrospective study, the implementation of universal patient and physician masking as practiced during the COVID-19 pandemic did not significantly affect the rate of postintravitreal injection endophthalmitis.

ABSTRACT

INTRODUCTION: Age-related macular degeneration (AMD) is a common cause of visual impairment, affecting central vision. Geographic atrophy (GA) is an advanced form of the non-neovascular (dry) type of AMD. Late-stage clinical trials suggest that intravitreal injections of novel therapeutics may slow down the rate of GA progression by up to 30% in 1 year, thus allowing people with GA to preserve central vision for a longer period. While intravitreal injections have become an established treatment modality for neovascular (wet) AMD, it is unknown whether patients with (more gradually progressing) GA would accept regular injections that slow down, but do not stop or reverse, vision loss. Therefore, this mixed-methods pilot study will aim to explore whether regular intravitreal injections will be acceptable as treatment for patients with GA, and the factors that may affect treatment acceptability. METHODS AND ANALYSIS: A mixed-methods survey has been designed in collaboration with a GA patient advisory group. The survey comprises of structured questionnaires, semi-structured interview questions regarding patients' perceptions of intravitreal injections and the burden of treatment, and a task eliciting preferences between different potential treatments. Due to COVID-19 restrictions, this study will be conducted remotely by telephone. Thirty individuals will be recruited from NHS Medical Retina clinics at Central Middlesex Hospital, London. Half of the participants will be naïve to intravitreal injections, while half will have previous experience of intravitreal injections for neovascular (wet) AMD. Qualitative data analysis will be conducted using the Framework Method of analysis to identify key themes from participants' accounts. ETHICS AND DISSEMINATION: The study received Health Research Authority approval on 23 March 2021 (IRAS Project ID: 287824). Findings will be disseminated through peer-reviewed publications and conference presentations to the medical retina community, as well as through dialogue with patients and macular disease charities.

ABSTRACT

PURPOSE: To investigate the adherence rate of neovascular age-related macular degeneration (nAMD) patients in treat-and-extend (TAE) protocol to their anti-vascular endothelial growth factor (anti-VEGF) intravitreal injection (IVI) appointments and to evaluate the functional and anatomical outcomes of the patients who attended and did not attend their IVI appointments during the coronavirus disease 2019 (COVID-19) restriction period (RP). METHODS: The patients with nAMD having IVI appointments between March 16 and June 1, 2020 (RP in Turkey) were included in this retrospective study. For adherence analysis, the patients who attended (Group 1, n = 44) and who did not attend (Group 2, n = 60) their IVI appointment visits during the RP (VRP) were evaluated according to their last visit before the RP (V0). For outcome analysis, the patients who attend VRP and have follow-up (Group 1a, 46 eyes) and who did not attend VRP but later attended for follow-up (Group 2a, 33 eyes) were evaluated for functional (best-corrected visual acuity, BCVA [logMAR]) and anatomical (optical coherence tomography [OCT] disease activity) outcomes at the first visit after RP (V1) and last visit within six months after RP (V2). Patients received a complete ophthalmologic evaluation with anti-VEGF (Aflibercept) IVI administration at all visits. RESULTS: The adherence rate of the patients to VRP was 42.3% (44/104). The patients in Group 1 were significantly younger (mean ± SD years, 71.0 ± 8.1 vs. 74.7 ± 8.0, p = 0.024), had better median [IQR] BCVA at their first presentation (0.30 [0.54] vs. 0.61 [1.08], p = 0.023) and V0 (0.40 [0.48] vs. 0.52 [0.70], p = 0.031), and had less hypertension (36.4% vs. 58.3%, p = 0.044) than Group 2. The mean ± SD delay of planned IVI at VRP in Group 2a was 13.9 ± 6.2 weeks. Disease activity in OCT was significantly higher in Group 2a than Group 1a at V1 (60.6% vs. 32.6%, p = 0.025). In Group 2a, the median (IQR) BCVA was significantly worse at V1 (0.70 [0.58]) and V2 (0.70 [0.59]) than V0 (0.52 [0.40], p = 0.047 and p = 0.035, respectively). CONCLUSIONS: More than half of the scheduled nAMD patients in TAE protocol missed their IVI visits during the RP, which resulted in a delay of their treatments. The delay of IVI treatment in those patients resulted in an increase in OCT disease activity and a decrease in BCVA.

ABSTRACT

OBJECTIVES: To investigate the effects of the COVID-19 pandemic on the treatment course of neovascular age-related macular degeneration (nAMD) patients who received anti-VEGF injection therapy with real-life data. METHODS: This retrospective study consisted of 116 eyes of 106 patients. Ophthalmic examination, assessment of best-corrected visual acuity (BCVA), optical coherence tomography (OCT) findings and data of last two visits before restrictions (V-2 and V-1) and the first visit (V0) after the release of national lockdown and subsequent visits (V1 and Vlast) were recorded. The lockdown period was determined by the time interval between March 11 and June 1, 2020. MAIN RESULTS: The injection interval before V-1 was significantly longer than the interval after V0 (2.56±0.9 vs. 2.14±0.8 months, P=0.02). While the median central macular thickness (CMT) was significantly increased at V0 compared to V-1 [274(132-711) vs. 238(136-628), P<0.001], the median CMT was significantly lower at V1 compared to V0 [256 (136-591) vs. 274(132-711), P=0.003]. The median BCVA was 0.67(0.1-1.1) logMAR at V-1 and significantly worsened to 0.78 (0.1-1.2) logMAR at V0 (P=0.003). Although the median BCVA improved to 0.69 logMAR (0.1-1.2) at Vlast, the difference did not reach statistical significance compared to V0 (P=0.08). CONCLUSION: Treatment delay due to the COVID-19 pandemic cause progression of nAMD and visual impairment. To plan more frequent anti-VEGF treatments and visits may be an appropriate approach until the disease stabilizes. However, it should be kept in mind that despite the improvement in OCT findings, the desired success in VA could not be achieved in the short term.

ABSTRACT

On the basis of Covid-19-induced pulmonary pathological and vascular changes, we hypothesize that the anti-vascular endothelial growth factor (VEGF) drug bevacizumab might be beneficial for treating Covid-19 patients. From Feb 15 to April 5, 2020, we conducted a single-arm trial (NCT04275414) and recruited 26 patients from 2-centers (China and Italy) with severe Covid-19, with respiratory rate ≥30 times/min, oxygen saturation ≤93% with ambient air, or partial arterial oxygen pressure to fraction of inspiration O2 ratio (PaO2/FiO2) >100 mmHg and ≤300 mmHg, and diffuse pneumonia confirmed by chest imaging. Followed up for 28 days. Among these, bevacizumab plus standard care markedly improves the PaO2/FiO2 ratios at days 1 and 7. By day 28, 24 (92%) patients show improvement in oxygen-support status, 17 (65%) patients are discharged, and none show worsen oxygen-support status nor die. Significant reduction of lesion areas/ratios are shown in chest computed tomography (CT) or X-ray within 7 days. Of 14 patients with fever, body temperature normalizes within 72 h in 13 (93%) patients. Relative to comparable controls, bevacizumab shows clinical efficacy by improving oxygenation and shortening oxygen-support duration. Our findings suggest bevacizumab plus standard care is highly beneficial for patients with severe Covid-19. Randomized controlled trial is warranted.

ABSTRACT

BACKGROUND: The aims of this study were to provide real-life data about the effect of COVID-19 pandemic on the practice of anti-VEGF injections and to evaluate the safety of the modifications in the injection protocol imposed during the ongoing pandemic on the anatomical and functional outcome of patients. METHODS: All patients attending Tanta University hospital for receiving intravitreal anti-VEGF injections were screened. Patients who were previously deferred according to a modified protocol implemented in the hospital in response to the pandemic or who demonstrated deviation from it were included for further analysis. RESULTS: During the audit period, 83 patients attending for anti-VEGF injections were screened, of whom 40 met the abovementioned criteria and were included for analysis. In the deferred subgroup (11 eyes), predeferral mean values of logMAR best corrected visual acuity (BCVA) and central retinal subfield thickness (CST) were 1 ± 0.23 and 444.57 ± 200.1 µm, respectively. There was no significant change when the patients returned for their deferred injections, with the mean BCVA and CST values being 0.8 ± 0.22 and 413.71 ± 237.7 µm, respectively (p = 0.27 and p = 0.12). Moreover, 29 patients encountered a disturbed injection schedule, particularly skipping their injection appointments due to infection fear as found in 18 patients. CONCLUSION: The COVID-19 pandemic has imposed pressing challenges in maintaining essential health care while ensuring the prevention of spread of infection. Although the modified injection protocol confirmed to be safe for patients, the pandemic caused deflection from the optimum practice in the form of successive skipping of appointments and delays in the processing of patient injection schedules.

ABSTRACT

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.

ABSTRACT

In the last months, a rapidly increasing number of people have been infected with severe acute respiratory syndrome coronavirus 2, the virus causing coronavirus disease 2019 (COVID-19). Due to the risk of cross-infections, the number of visits and injections was dramatically reduced in the last months, and the time between visits has been rescheduled from every 15 to 45 min, significantly impairing the total number of available visits. Although continuity of care has been allowed, a series of measures to diminish the risk of contamination need to be adopted until the end of this pandemic outbreak, which may persist until the development of an effective vaccine. For these reasons, we have introduced a new treatment regimen that is aimed at reducing the number of in-person visits and achieving continuity of treatment. This regimen is named "Triple and Plan" (TriPla). The main advantage of the TriPla regimen is to reduce the number of visits of patients in comparison to the pro re nata and treat and extend regimen. Using the TriPla regimen, the risk of contamination would be reduced. Furthermore, by reducing the number of scheduled visits, physicians could guarantee an adequate number of examinations for each patient, lengthening the interval between visits, and reducing the risk of cross-infections.

ABSTRACT

PURPOSE: To estimate the impact of delayed care during the coronavirus disease 2019 (COVID-19) pandemic on the outcomes of patients with neovascular age-related macular degeneration (AMD). METHODS: Consecutive patients with diagnosis of neovascular AMD were consecutively enrolled between March 9, 2020, and June 12, 2020, (during and immediately after the Italian COVID-19 quarantine). During the inclusion (or pandemic) visit (V0), patients received a complete ophthalmologic evaluation, including optical coherence tomography (OCT). Best-corrected visual acuity (BCVA) and OCT findings from the two preceding visits (V-1 and V-2) were compared with data at V0. RESULTS: One-hundred patients (112 eyes) were enrolled in this study. The time interval between following visits was 110.7 ± 37.5 days within V0 and V-1 and 80.8 ± 39.7 days within V-1 and V-2, respectively (P < 0.0001). BCVA was statistically worse at the V0 visit as compared with the immediately preceding (V-1) visit (0.50 ± 0.43 LogMAR and 0.45 ± 0.38 LogMAR at the V0 and V-1 visits, respectively; P = 0.046). On structural OCT, 91 out of 112 (81.2%) neovascular AMD eyes displayed the evidence of exudative disease activity at the V0 visit, while 77 (68.7%) eyes exhibited signs of exudation at the V-1 visit (P = 0.022). No differences in terms of BCVA and OCT findings were detected between the V-1 and V-2 visits. In multiple regression analysis, the difference in BCVA between V0 and V-1 visits was significantly associated with the interval time within these two visits (P = 0.026). CONCLUSION: The COVID-19 pandemic-related postponement in patient care proved to be significantly associated with worse short-term outcomes in these patients.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is a form of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has been declared a pandemic by the World Health Organization (WHO). Ocular manifestations related to COVID-19 are uncommon with conjunctivitis being reported in a few cases. We report a unique case of vasculitic retinal vein occlusion (RVO) secondary to COVID-19 in a 52-year-old patient who presented with the diminution of vision in the left eye 10 days after he tested positive for SARS-CoV-2. All investigations for vasculitis were negative. This case supports the mechanism of thrombo-inflammatory state secondary to the "cytokine-storm" as the pathogenesis for systemic manifestations of COVID-19.

ABSTRACT

PURPOSE: To quantify the shrinking in outpatient and intravitreal injections' volumes in a tertiary referral retina unit secondary to virus causing coronavirus disease 2019 (COVID-19). METHODS: In this retrospective cross-sectional study, we reviewed the charts of all patients who had a visit at a medical retina referral center during the Italian quarantine (from 9th of March 2020 to 3rd of May 2020). Number and characteristics of these data were compared with data from the same period in 2019 (from 9th of March 2019 to 3rd of May 2019). RESULTS: In the 2019 study period, there were 303 patients attending clinic (150 males, 153 females). In the 2020 study period, patients decreased to 75 (48 males, 27 females; P = 0.022 comparing gender prevalence between the two periods) with an overall reduction of 75.2%. Mean ± SD age was 71.4 ± 14.3 years (range 25-93 years) in the 2019 study period and 66.7 ± 13.1 years (range 32-91 years) in the 2020 study period (P = 0.005). The largest drop in outpatient volume was recorded in AMD patients (- 79.9%). Regarding the intravitreal treatments, there were 1252 injections in the 2019 period and 583 injections in the 2020 period (- 53.6% in injections). The drop in intravitreal treatments was larger in patients with posterior uveitis, retinal vein occlusion, and diabetes (- 85.7%, - 61.9%, and - 59.6%, respectively). CONCLUSION: The volume of outpatient visits and intravitreal injections declined during the COVID-19 quarantine. The short- and long-term impacts are that routine in-person visits and intravitreal injections are expected to increase after the quarantine and, even more, after the pandemic.
