Deep learning-based algorithm for the detection of idiopathic full thickness macular holes in spectral domain optical coherence tomography.

BACKGROUND: Automated identification of spectral domain optical coherence tomography (SD-OCT) features can improve retina clinic workflow efficiency as they are able to detect pathologic findings. The purpose of this study was to test a deep learning (DL)-based algorithm for the identification of Idiopathic Full Thickness Macular Hole (IFTMH) features and stages of severity in SD-OCT B-scans. METHODS: In this cross-sectional study, subjects solely diagnosed with either IFTMH or Posterior Vitreous Detachment (PVD) were identified excluding secondary causes of macular holes, any concurrent maculopathies, or incomplete records. SD-OCT scans (512 × 128) from all subjects were acquired with CIRRUS™ HD-OCT (ZEISS, Dublin, CA) and reviewed for quality. In order to establish a ground truth classification, each SD-OCT B-scan was labeled by two trained graders and adjudicated by a retina specialist when applicable. Two test sets were built based on different gold-standard classification methods. The sensitivity, specificity and accuracy of the algorithm to identify IFTMH features in SD-OCT B-scans were determined. Spearman's correlation was run to examine if the algorithm's probability score was associated with the severity stages of IFTMH. RESULTS: Six hundred and one SD-OCT cube scans from 601 subjects (299 with IFTMH and 302 with PVD) were used. A total of 76,928 individual SD-OCT B-scans were labeled gradable by the algorithm and yielded an accuracy of 88.5% (test set 1, 33,024 B-scans) and 91.4% (test set 2, 43,904 B-scans) in identifying SD-OCT features of IFTMHs. A Spearman's correlation coefficient of 0.15 was achieved between the algorithm's probability score and the stages of the 299 (47 [15.7%] stage 2, 56 [18.7%] stage 3 and 196 [65.6%] stage 4) IFTMHs cubes studied. CONCLUSIONS: The DL-based algorithm was able to accurately detect IFTMHs features on individual SD-OCT B-scans in both test sets. However, there was a low correlation between the algorithm's probability score and IFTMH severity stages. The algorithm may serve as a clinical decision support tool that assists with the identification of IFTMHs. Further training is necessary for the algorithm to identify stages of IFTMHs.

Most cited articles involving lacrosse since 1990 primarily focus on concussion and traumatic brain injury.

OBJECTIVES: The purpose of this study was to identify the 50 most-cited publications relating to lacrosse since 1990 and conduct a bibliometric analysis of the identified studies. METHODS: Clarivate Analytics Web of Science database was queried to identify all publication titles, abstracts, and keywords for the term 'lacrosse' on 9 June 2023. The resulting articles were sorted by total number of citations. Titles and abstracts were included based on their relevance to lacrosse. Once the 50 most cited articles were identified, each article was further analyzed to obtain author name, publication year, country of origin, journal name, article type, research topic, competition level, total number of citations, and the level of evidence. Citation density (total number of citations/years since publication) was calculated and recorded for each of the most-cited studies. RESULTS: The 50 most-cited articles were cited 4237 of times with an average of 84 citations per article. The most cited article was cited 637 (15.0%) times. The articles came from 2 different countries, with the United States and Australia comprising 49 and 1 articles, respectively. All articles were published in English. The American Journal of Sports Medicine published the most articles (n = 21, 42.0%). The most studied topic was concussion/traumatic brain injury (n = 18) followed by studies assessing all injuries (n = 7). Collegiate-level lacrosse was the most studied level of competition (n = 22), while high school-level followed (n = 12). CONCLUSIONS: The majority of the 50 most-cited articles related to lacrosse since 1990 focus on the prevalence, diagnosis and identification of concussion/traumatic brain injury in high school and collegiate-level athletes. These articles are predominantly epidemiological or cohort studies with Level III or IV evidence that almost unanimously originate from the United States.

Predictors of response to a lapse in anti-VEGF treatment in patients with macular edema secondary to retinal vein occlusion.

BACKGROUND: Macular edema (ME) in the setting of retinal vein occlusions (RVO) is a common cause of vision loss worldwide. Anti-vascular endothelial growth factor (anti-VEGF) injections are the gold standard for ME secondary to RVO. Despite their efficacy, anti-VEGF injections carry significant burdens for patients, resulting in high rates of loss to follow-up and treatment lapses. METHODS: A sub-analysis examining the effects of a treatment lapse in RVO patients was conducted. Sixty patients were included and separated into vision-loss and stable-vision groups based on change in vision after a lapse. A logistic regression with age, body mass index (BMI), history of dyslipidemia, and time since diagnosis of RVO as predictors was used to predict whether patients would experience vision loss after a lapse. RESULTS: The average lapse was 5.6 months and similar in the vision-loss and stable-vision groups. At baseline, the vision-loss group was older and had a lower BMI (p < 0.05). Age and history of dyslipidemia increased the odds of vision loss by factors of 1.23 (range, 1.10-1.45) and 8.40 (range, 1.62-66.2), respectively. BMI and time since RVO diagnosis decreased the odds of vision loss by factors of 0.83 (range, 0.69-0.95) and 0.95 (range, 0.90-0.99), respectively. The final model had a specificity of 87.5% and a sensitivity of 70.0%. CONCLUSIONS: Patients' responses to treatment lapses for ME secondary to RVO can be predicted with reasonable accuracy using readily available clinical data, particularly age, BMI, time since diagnosis, and history of dyslipidemia. Providers should consider these factors when counselling patients and determining follow-up schedules.

Perioperative COVID-19 Screening at a Tertiary Ophthalmic Institution.

Purpose: To characterize the rate of COVID-19 positivity during presurgical screening and the surgical outcomes of ophthalmic patients who were positive for COVID-19 and to report the overall cost. Methods: This retrospective study included patients 18 years or older who had ophthalmic surgical procedures at a tertiary institution between May 11, 2020, and December 31, 2020. Patients without a valid presurgical COVID-19 test within 3 days before their scheduled procedure, who had incomplete or mislabeled visits, or who had incomplete or missing data in their file were excluded. COVID-19 screening was completed using a polymerase chain reaction (PCR) kit. Results: Of the 3585 patients who met the inclusion criteria, 2044 (57.02%) were women; the mean age was 68.2 years ± 12.8 (SD). Thirteen asymptomatic patients (0.36%) tested positive for COVID-19 via PCR screening. Three patients had a known positive COVID-19 infection within the 90 days before surgery; thus, 10 patients (0.28%) were found to have asymptomatic naïve COVID-19 infection via PCR testing. Testing was associated with a total charge of US $800 000. Five of the 13 patients (38.46%) who tested positive for COVID-19 experienced a delay in their surgery; the mean delay was 17.23 ± 22.97 days. Conclusions: Asymptomatic ophthalmic surgical patients had a low positivity rate with a limited impact on surgery scheduling at a significant cost. Further studies would be valuable in evaluating a targeted presurgical screening population as opposed to universal testing.

Functional Imaging of Mitochondria in Age-Related Macular Degeneration Using Flavoprotein Fluorescence.

PURPOSE: Oxidative stress-induced mitochondrial dysfunction is implicated in the pathogenesis of age-related macular degeneration (AMD). Oxidized mitochondrial flavoprotein fluorescence (FPF) may serve as a quantifiable biomarker of oxidative stress, reported as either mean score for the entire image (intensity) or variability (heterogeneity). This study examines FPF intensity and heterogeneity across a large patient cohort of various Beckman stages of AMD. METHODS: This study enrolled patients with isolated AMD and healthy control patients with no retinopathy between 2018 and 2021. Multivariate logistic regression analysis included stage of AMD, age, gender, ethnicity, and smoking status. Analysis of Variance test compared mean FPF intensity and heterogeneity between disease states. RESULTS: Four hundred fifty-six eyes (228 AMD eyes, 228 age-matched control eyes) were included in the final multivariate analysis. Intermediate, geographic atrophy (GA), and neovascular AMD correlated with significantly increased FPF intensity (P < 0.001, respectively), while all AMD stages correlated with increased FPF heterogeneity (P < 0.001, respectively). FPF intensity and heterogeneity were significant negative predictors of visual acuity (P = 0.018 and 0.024, respectively). CONCLUSIONS: This prospective observational study further implicates mitochondrial damage in AMD pathophysiology. Long-term clinical trials will be needed to examine the predictive role of FPF imaging in patients over time. [Ophthalmic Surg Lasers Imaging Retina 2023;54:24-31.].

Impact of retinal fluid in patients with diabetic macular edema treated with anti-VEGF in routine clinical practice.

OBJECTIVE: This study aims to determine the effect of intraretinal (IRF) and subretinal (SRF) fluid on visual outcomes for diabetic macular edema (DME) patients treated with anti-vascular endothelial growth factor (anti-VEGF) in routine clinical practice. DESIGN: Optical coherence tomography scans were analyzed with a deep-learning artificial intelligence software to quantify IRF, SRF, and total retinal fluid (TRF) at baseline and at 3, 6, and 12 months. Predictive variables for best-corrected visual acuity (BCVA) were evaluated with linear mixed-effects regression models. PARTICIPANTS: A total of 220 DME eyes of 220 patients from the Cole Eye Institute at Cleveland Clinic. METHODS: Retrospective, nonrandomized cohort study. RESULTS: BCVA improved from baseline to 12 months (63.36 ± 14.72 to 68.49 ± 13.14 Early Treatment Diabetic Retinopathy Study letters, p < 0.001, respectively). Central subfield thickness improved from baseline to 12 months (411.74 ± 129.7 to 335.94 ± 116.91 mm, p < 0.001, respectively). Injection frequency per patient was 8.25 ± 2.5 injections over 12 months. The linear mixed-effects regression model in the foveal region for TRF, IRF, and SRF volume at the fourth quartile showed BCVA losses of -8.29 letters (range, -10.96 to -5.62 letters, p < 0.001), -7.52 letters (range, -10.3 to -4.74 letters, p < .001), and -6.93 letters (range, -10.54 to -3.41 letters, p < .001), respectively. CONCLUSIONS: The highest quartile of TRF, IRF, and SRF volumes led to worse visual outcomes after 12 months of anti-VEGF treatment in patients with DME. Further studies designed to investigate the effect of anti-VEGF treatment on retinal fluid morphology could provide greater insight into individualized DME treatment.

Characterization of ophthalmology virtual visits during the COVID-19 pandemic.

OBJECTIVES: To characterize the use of virtual visits, as well as compare the characteristics to in-person visits during the pandemic period. METHODS: This retrospective study included patients who had virtual and in-person ophthalmology visits from March 19, 2020, to July 31, 2020, in a large multispecialty ophthalmic center. Exclusion criteria included patients aged less than 18 years old; canceled, incomplete, mislabelled, and duplicated visits. 2943 virtual and 56,174 in-person visits were identified. A random sample of 3000 in-person visits was created. Each visit was analyzed as an individual data point. RESULTS: 2,266 virtual visits (2,049 patients, 64.3% female, mean [SD] age 64.3 [16.6] years old) and 2590 in-person visits (2509 patients, 59.5% female, 65.9 [15.8] years old) were included. Most virtual visits were classified as comprehensive ophthalmology (34.6%), optometry-related (19.5%), and oculoplastics (13.0%). For in-person visits, the most common specialties were optometry (29.8%), comprehensive ophthalmology (23.9%), and retina and uveitis (17.3%). The most common diagnoses in the virtual group were from the eyelids, lacrimal system, and orbits group (26.9%), while in the in-person groups were choroid and retina conditions (19.3%). CONCLUSIONS: Numerous ocular conditions were evaluated and managed through virtual visits, and external complaints and oculoplastic consults appear to be well-suited to the virtual format. Further studies focusing on visual outcomes and patient experience will be beneficial.

Consequences of anti-vascular endothelial growth factor treatment lapse in patients with retinal vein occlusion.

BACKGROUND: Anti-vascular endothelial growth factor (VEGF) treatments are the first-line treatment for Retinal Vein Occlusion (RVO). Although effectiveness and safety of these treatments is well documented, knowledge regarding the effect of lapses in anti-VEGF treatment among RVO patients is lacking. The purpose of this study is to analyse the anatomic and visual outcomes from a lapse in anti-VEGF treatment in patients with RVO. METHODS: This retrospective case-control study evaluated 136 patients diagnosed with RVO and treated with anti-VEGF between January 2012 and June 2020 at Cole Eye Institute, Cleveland Clinic. Patients were divided into two cohorts: RVO patients with no lapse in anti-VEGF treatment (control group) and RVO patients with a lapse ≥3 months (lapse group). Central subfield thickness (CST) and best corrected visual acuity (BCVA) were collected pre-lapse, the first appointment post-lapse, and at 3-, 6-, and 12-month follow-up appointments. RESULTS: Lapse patients (n = 68) and control patients (n = 68) had similar pre-lapse CST (p = 0.466) and BCVA (p = 0.303). Lapse patients experienced a significant increase in CST after discontinuing anti-VEGF therapy (lapse: 400.6 ± 192.1 µm, control: 333.0 ± 111.1 µm, p = 0.024). This persisted 12 months post-lapse after re-initiation of anti-VEGF agents (lapse: 381.6 ± 161.1 µm, control: 307.5 ± 95.4 µm, p = 0.030). Lapse patients also experienced a decrease in BCVA after lapse (lapse: 54.3 ± 25.1 ETDRS, control: 64.4 ± 17.8 ETDRS, p < 0.001) that recovered after 6 months of anti-VEGF treatment. CONCLUSIONS: RVO patients with any lapse of anti-VEGF treatment are at risk for poorer anatomic and visual outcomes. Though BCVA normalizes upon treatment resumption, patients experience a statistically significant increase in CST that does not recover.

Interventions to reduce loss to follow up in common retinal pathology: A systematic review.

PURPOSE: Loss to follow-up or fragmented follow-up episodes (LTFU) may contribute to suboptimal clinical outcomes, especially when comparing real world data to clinical trials. This systemic review gathers available evidence around interventions meant to decrease the LTFU in AMD, RVO, and DME patients. PATIENTS AND METHODS: PubMed was queried using a literature search strategy and reviewed by the authors. Studies with interventions aimed at reducing lost to follow up were included. RESULTS: Ten studies were extracted from 89 candidate publications. DISCUSSION: Telephone interventions featuring assistance in scheduling in improving LTFU in urban, African American populations over 50 years old with diabetic retinopathy. The same interventions have shown promise in glaucoma, but remain understudied in AMD, RVO, and other geographic, ethnic, and socioeconomic demographics. CONCLUSION: No sole intervention with efficacy in improving LTFU has been developed. A standardized definition of LTFU, as well as testing interventions across broad age, geography, ethnic, racial, and socioeconomic lines. Longitudinal data would also add credence to the efficacy of purported interventions. OTHER: No sources of funding for this article.

Rhegmatogenous Retinal Detachment: Variations in Clinical Presentation and Surgical Outcomes by Socioeconomic Status and Race.

BACKGROUND AND OBJECTIVE: To characterize rhegmatogenous retinal detachment (RRD) presentation and repair outcomes by race and socioeconomic status. MATERIALS AND METHODS: Retrospective cohort one-center study of adults with a new RRD repair from 2012 to 2020. Logistic and linear regression analyses were conducted. RESULTS: 61.7% were male, 84.5% White and 9.4% Black (total n = 1092). 95.8% White and 94.2% Black patients had retinal reattachment (P = .234). Macula-off status was more likely with Medicare/Medicaid than private insurance (OR 1.63, 95% CI 1.11 to 2.41, P = .014); and less likely with higher income (OR 0.88, CI 0.81 to 0.96, P = .003). Black patients had worse best visual acuity (BVA) at presentation and follow-up (follow-up -6.93 letters, CI -13.19 to -0.64, P = .031), and higher odds of postoperative ocular hypertension (OHTN) (OR 2.41, CI 1.28 to 4.60, P = .007). CONCLUSIONS: Despite equivalent retinal reattachment rates, Black patients have worse BVA, and are more likely to develop OHTN than White patients. Macula-off status is less likely in patients with higher income or private insurance. [Ophthalmic Surg Lasers Imaging Retina 2022;53:538-545.].

Assessment of freely available online videos of cardiac electrophysiological procedures from a shared decision-making perspective.

Background: Physicians recommend electrophysiological (EP) procedures to patients with arrhythmic risk. This involves shared decision-making (SDM). Patients increasingly search for additional information online. Freely available online videos are an attractive source. Objective: We assessed freely available online videos for EP procedures from the perspective of SDM to determine if such videos can be shared with patients for SDM. Methods: We searched for freely available online videos related to 6 common EP procedures limited to English language and duration between 1 and 10 minutes using Google and Bing. Data collected included date and source of upload, number of hits, and duration. Videos were assessed systematically for understandability, actionability (PEMAT tool), relatability, teamwork, and mention of risk. Results: A total of 78 videos met our inclusion criteria, out of 960 video links. Overall inter-rater agreement was moderate to good. Video upload dates spanned 12 years and number of hits ranged from 87 to 594,000. The majority of videos (63%) were produced by health care systems or academic institutions. For all 78 videos the mean total PEMAT tool score was 48.6%. Thirty-five percent of videos showed a patient engaged in a conversation with the physician or a team member; 41% of videos showed other team members. The potential for complications was mentioned in 10%. Conclusion: The majority of online, freely available videos for common EP procedures lack features useful for SDM and may not be helpful for sharing with patients from that perspective. It is possible to create high-quality videos that can facilitate SDM.

Association of Socioeconomic Health Care Disparities With Use of Anti-Vascular Endothelial Growth Factor and Visual Acuity Outcomes in Patients With Diabetic Macular Edema.

BACKGROUND AND OBJECTIVE: This study characterizes the impact of race, ethnicity, insurance status, and geographic location on anti-vascular endothelial growth factor (VEGF) use for the treatment of diabetic macular edema (DME). PATIENTS AND METHODS: This study is a retrospective cohort study. The American Academy of Ophthalmology Intelligent Research in Sight Registry was queried for patients diagnosed with DME who received at least one anti-VEGF injection between 2012 and 2020 (n = 203,707). Multivariate regression analyses investigated associations between race, ethnicity, insurance status, and geographic location and anti-VEGF use and visual outcomes. RESULTS: White race, non-Hispanic/Latino ethnicity, and private insurance were associated with higher use of anti-VEGF injections during a 60-month period (incidence rate ratio, 1.2, 1.25, and 1.17, respectively; P < .01). Furthermore, being of non-Hispanic/Latino ethnicity and having private health insurance were associated with higher longitudinal visual acuity (odds ratio, 1.44 [P = .02] and odds ratio, 1.43 [P < .01], respectively). CONCLUSION: Ethnicity and insurance status are associated with anti-VEGF use and visual acuity outcomes in DME. [Ophthalmic Surg Lasers Imaging Retina 2022; 53:380-391.].

Impact of Persistent Retinal Fluid in Patients with Neovascular Age-Related Macular Degeneration in Routine Clinical Practice.

BACKGROUND AND OBJECTIVE: To determine whether quantification of intraretinal fluid (IRF) and subretinal fluid (SRF) can be used as a biomarker for predicting visual prognosis in routine clinical practice. PATIENTS AND METHODS: Retrospective, nonrandomized cohort study review of patients with neovascular age-related macular degeneration from January 1, 2012, to March 1, 2018. RESULTS: In the 286-patient cohort, the mean baseline, 6-month, and 12-month best-corrected visual acuity (BCVA) was 60.24 ± 18.63, 65.57 ± 16.56, and 65.61 ± 17.37 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, respectively (P < .001). The regression coefficient in the linear mixed effects regression model quantifying the association between eyes in the fourth and first quartile of IRF and 12-month BCVA was -4.14 (95% CI, -6.65 to -1.63) (P = .001) ETDRS letters. The regression coefficient quantifying the association between eyes in the fourth and first quartile of SRF and 12-month BCVA was -0.7 (95% CI, -3.07 to 1.27) (P = .56) ETDRS letters. CONCLUSION: IRF and SRF are valuable biomarkers for BCVA outcomes in treatment-naïve neovascular age-related macular degeneration in routine clinical practice.

Influence of Race, Ethnicity, and Socioeconomic Factors in Idiopathic Macular Hole Presentation and Surgical Outcomes.

BACKGROUND AND OBJECTIVE: To characterize the influence of race, ethnicity, and socioeconomic factors on idiopathic macular hole (IMH) presentation and surgical outcomes. PATIENTS AND METHODS: This retrospective cohort study of patients diagnosed with IMH who underwent surgical repair collected IMH data from optical coherence tomography scans as well as demographic information. Univariate and multivariate regression models interrogated relevant relationships. RESULTS: Of 292 eyes analyzed, 223 (76.4%) patients were White and 53 (18.2%) were Black. Mean income was $57,076.9 ± 17,794.7. Black patients presented with 0.05 mm2 larger IMH area (95% CI, 0.01 to 0.09; P = .01) and 69.07 µm wider minimum linear diameter (95% CI, 15.05 to 123.10; P = .01). Patients with higher income presented with 3.76 µm narrower base diameter (95% CI, -6.42 to -1.09; P = .006). CONCLUSIONS: Black patients were associated with larger IMH at presentation, and higher income patients were associated with smaller IMH.

Progression to Vision-Threatening Retinopathy Complications Following Panretinal Laser for Proliferative Diabetic Retinopathy.

BACKGROUND AND OBJECTIVE: To report the time in which patients with panretinal photocoagulation (PDR) progress to vision-threatening retinopathy (VTR) complications after receiving PRP, and risk factors in routine clinical practice. PATIENTS AND METHODS: Records of patients with complete PRP for PDR were retrospectively reviewed for up to 3.5 years after PRP. Two hundred twenty eyes were selected. RESULTS: Time from PRP to VTR was 1.25 ± 0.82 years. Age, Black race, neovascularization of the disc on examination, diabetic foot disease (DFD), and high-risk PDR characteristics on fluorescein angiography were identified as significant risk factors. Half of patients with DFD on examination developed a VTR within 1.5 years after PRP (P < .001). CONCLUSION: In clinical practice, providers may consider DFD and Black race as predictors of time to VTR event within 4 years after PRP in patients with PDR.

The Quantification and Impact of Persistent Retinal Fluid Compartments on Best-Corrected Visual Acuity of Patients With Retinal Vein Occlusion.

BACKGROUND AND OBJECTIVES: To evaluate the impact of persistent intraretinal fluid (IRF) and subretinal fluid (SRF) on best visual acuity (BVA) of patients with retinal vein occlusions (RVOs). PATIENTS AND METHODS: This retrospective cohort study observed 92 treatment-naïve patients with RVO during 12 months of treatment with anti-vascular endothelial growth factor agents. Deep learning was used to quantify IRF and SRF volumes, and linear mixed effects regression modeled the impact on BVA. RESULTS: Average IRF volume declined -923.1 ± 2,382.5 nL from baseline to 12 months (P < .001). Average SRF volume declined -35.4 ± 223.4 nL from baseline to 12 months (P = .139). linear mixed effects regression modeling disclosed IRF≥ 1,616 nL at all time points predicted a -10.38 letter loss at 12 months (95% CI, -14.58 to -5.9 letters; P < .001). A similar relationship was not found for SRF. CONCLUSION: Persistent IRF may be an important prognostic biomarker for BVA outcomes in real-world patients with RVO.

Performance of a Machine-Learning Computational Image Analysis Algorithm in Retinal Fluid Quantification for Patients With Diabetic Macular Edema and Retinal Vein Occlusions.

BACKGROUND AND OBJECTIVE: The objective is to validate an automated artificial intelligence model in detecting and quantifying fluid in diabetic macular edema (DME) and retinal vein occlusion (RVO) optical coherence tomography images. PATIENTS AND METHODS: DME (n = 100) and RVO (n = 100) images of adult patients were reviewed. The performance of machine-learning (ML) computational image analysis algorithm was evaluated against consensus manual grading. Main outcomes were accuracy and sensitivity for detection and Pearson's correlation coefficients for quantification. RESULTS: The ML algorithm had a high accuracy and sensitivity in both DME (intraretinal fluid [IRF]: 0.92, 0.97; subretinal fluid [SRF]: 0.93, 1.00) and RVO (IRF: 0.94, 0.99; SRF: 0.93, 1.00). It had moderate-high correlation in quantifying fluid in DME (total retinal fluid: 0.88; IRF: 0.88; SRF: 0.97) and RVO (total retinal fluid: 0.83; IRF: 0.76; SRF: 0.64). CONCLUSION: The ML algorithm is highly accurate and sensitive in detecting fluid in DME and RVO optical coherence tomography images and effectively quantifies IRF and SRF in both disease states, particularly in images with low to moderate fluid burden.

Ocular occupational injuries in the United States between 2011-2018.

BACKGROUND: Current advocacy literature in occupational eye injury focuses on demographics and industries with the largest number of injuries. Additional demographics may also benefit from targeted advocacy that experience a greater proportion of eye injuries relative to all other occupational injuries. AIMS: To characterize which demographic groups are experiencing occupational ocular injuries in the United States. METHODS: This cross-sectional study examined de-identified individuals who experienced ocular workplace injuries from 2011 to 2018 and were reported to the survey of occupational injuries and illnesses (SOII). Data were stratified and analysed based on SOII reported characteristics. RESULTS: 197 160 out of 9 197 350 (2%) ocular workplace injuries were reported. 152 940 (78%) injuries occurred in males. Relative to all workplace injuries experienced by industry, farming, fishing and forestry saw the highest percentage of ocular injuries (6%), followed by production, and installation (4%), maintenance and repairs (4%). Employers cited contact with objects (65%) and exposure to harmful substances (26%) as leading reasons for eye injury. Relative to all injuries, chemicals frequently injured the eye (27%). CONCLUSIONS: A disproportionate number of American ocular workplace injuries occur in males who are likely relatively young. Industries such as fishing, farming and forestry see a high frequency of ocular injury relative to all occupational injuries. Hispanics see a slight increase in ocular occupational injury relative to other injuries. Advocates of occupational ocular safety should consider expanding their targeted audiences to include individuals who are part of demographics and occupations that more frequently experience an ocular workplace injury relative to all injuries.

Patient Satisfaction in the Era of COVID-19: Virtual Visit versus In-person Visit Satisfaction.

SIGNIFICANCE: Teleophthalmology became widely used during the coronavirus 2019 pandemic; however, the quality of this care remains to be understood. PURPOSE: This study aimed to compare patient satisfaction levels from virtual and in-person visits based on post-visit surveys, as well as investigate demographic characteristics that may predict patient satisfaction with virtual visits. METHODS: Virtual (n = 2943) and in-person (n = 56,175) visits from March 19, 2020, to July 31, 2020, were identified using the electronic health record system. For in-person visits, a random subset of 3000 visits was acquired using a random number generator. Of these, 2266 virtual and 2590 in-person visits met the inclusion criteria. Patients who completed the Telemedicine for Medical Practice Survey and Medical Practice Survey were analyzed in this report. Nonparametric Mann-Whitney test was used to compare scores between groups. RESULTS: Two hundred eleven virtual patients (9.31%; 82 phone, 115 video, 14 hybrid) and 307 in-person patients (11.85%) completed the Telemedicine for Medical Practice Survey and Medical Practice Survey, respectively. Satisfaction scores were similar and high in both groups-virtual visit satisfaction scores averaged 4.82, whereas in-person visit satisfaction averaged 4.85 (P = .80, θ = 0.501 [0.493 to 0.509]). Only one question yielded significantly different satisfaction scores, and no demographic variables were significant predictors of satisfaction scores. CONCLUSIONS: Patient satisfaction is comparable between virtual and in-person visits, validating the continued usage of telemedicine for eye care visits.

Racial, Ethnic, and Insurance-Based Disparities Upon Initiation of Anti-Vascular Endothelial Growth Factor Therapy for Diabetic Macular Edema in the US.

PURPOSE: This study characterizes the association of risk factors including race, ethnicity, and insurance status with presenting visual acuity (VA) and diabetic retinopathy (DR) severity in patients initiating treatment with anti-vascular endothelial growth factor (VEGF) therapy for diabetic macular edema (DME). DESIGN: Retrospective, cross-sectional study. PARTICIPANTS: The Academy Intelligent Research in Sight (IRIS) Registry database was queried for patients who initiated anti-VEGF injection treatment for DME between 2012 and 2020 (n = 203 707). METHODS: Multivariate regression analyses were conducted to understand how race, ethnicity, insurance status, and geographic location were associated with baseline features. MAIN OUTCOME MEASURES: Visual acuity and DR severity. RESULTS: Patients on Medicare and private insurance presented with higher baseline VA compared with patients on Medicaid (median of 2.31 and 4.17 greater Early Treatment Diabetic Retinopathy Scale [ETDRS] letters, respectively P < 0.01). White and non-Hispanic patients presented with better VA compared with their counterparts (median of 0.68 and 2.53 greater ETDRS letters, respectively; P < 0.01). Black and Hispanic patients presented with a worse baseline DR severity compared with White and non-Hispanic patients (odds ratio, 1.23 and 1.71, respectively; P < 0.01). CONCLUSIONS: There are ethnic and insurance-based disparities in VA and disease severity upon initiation of anti-VEGF therapy for DME treatment. Public health initiatives could improve timely initiation of treatment.
