Benchmarking deep models on retinal fundus disease diagnosis and a large-scale dataset

Retinal fundus imaging contributes to monitoring the vision of patients by providing views of the interior surface of the eyes. Machine learning models greatly aided ophthalmologists in detecting retinal disorders from color fundus images. Hence, the quality of the data is pivotal for enhancing diagnosis algorithms, which ultimately benefits vision care and maintenance. To facilitate further research in this domain, we introduce the Eye Disease Diagnosis and Fundus Synthesis (EDDFS) dataset, comprising 28,877 fundus images. These include 15,000 healthy samples and a diverse range of images depicting various disorders such as diabetic retinopathy, age-related macular degeneration, glaucoma, pathological myopia, hypertension retinopathy, retinal vein occlusion, and Laser photocoagulation. In addition to providing the dataset, we propose a Transformer-joint convolution network for automated eye disease screening. Firstly, a co-attention structure is integrated to capture long-range attention information along with local features. Secondly, a cross-stage feature fusion module is designed to extract multi-level and disease-related information. By leveraging the dataset and our proposed network, we establish benchmarks for disease screening and grading tasks. Our experimental results underscore the network’s proficiency in both multi-label and single-label disease diagnosis, while also showcasing the dataset’s capability in supporting fundus synthesis. (The dataset and code will be available onhttps://github.com/xia-xx-cv/EDDFS_dataset.)

In Vivo Optical Coherence Elastography Unveils Spatial Variation of Human Corneal Stiffness.

The mechanical properties of corneal tissues play a crucial role in determining corneal shape and have significant implications in vision care. This study aimed to address the challenge of obtaining accurate in vivo data for the human cornea. We have developed a high-frequency optical coherence elastography (OCE) technique using shear-like antisymmetric (A0)-mode Lamb waves at frequencies above 10 kHz. By incorporating an anisotropic, nonlinear constitutive model and utilizing the acoustoelastic theory, we gained quantitative insights into the influence of corneal tension on wave speeds and elastic moduli. Our study revealed significant spatial variations in the shear modulus of the corneal stroma on healthy subjects for the first time. Over an age span from 21 to 34 (N = 6), the central corneas exhibited a mean shear modulus of 87 kPa, while the corneal periphery showed a significant decrease to 44 kPa. The central cornea's shear modulus decreases with age with a slope of -19 +/- 8 kPa per decade, whereas the periphery showed non-significant age dependence. The limbus demonstrated an increased shear modulus exceeding 100 kPa. We obtained wave displacement profiles that are consistent with highly anisotropic corneal tissues. Our approach enabled precise measurement of corneal tissue elastic moduli in situ with high precision (<7%) and high spatial resolution (<1 mm). Our results revealed significant stiffness variation from the central to peripheral corneas. The high-frequency OCE technique holds promise for biomechanical evaluation in clinical settings, providing valuable information for refractive surgeries, degenerative disorder diagnoses, and intraocular pressure assessments.

Health Management Service Models for the Elderly with Visual Impairment: A Scoping Review.

The incidence of visual impairment(VI) in older people is gradually increasing. This review aimed to summarise the evidence on existing health management models and strategies for older adults with VI to improve health-related and vision-related quality of life (QoL) in older people. Based on the framework of the scoping review methodology of Arksey and O'Malley (2005), a comprehensive literature search of relevant literature published between January 2010 and June 2022 in PubMed, CINAHL, EMBASE, Web of Science, Cochrane Library, CNKI, VIP, Wanfang database, Sinomed and the grey literature. Finally, 31 articles were included. The health management model had a multidisciplinary team low vision rehabilitation model, medical consortium two-way management model, low vision community comprehensive rehabilitation model, medical consortium-family contract service model, screening-referral-follow-up model, and three-level low vision care model. The health management strategy covers nine aspects, the combination of multi-element strategies is feasible, and network information technology has also shown positive results. In the future, under the Internet and hierarchical management model, we should provide demand-based personalized support to rationalize and scientifically achieve hierarchical management and improve resource utilization efficiency and eye health outcomes.

Addressing Disparities in Vision Health and Eye Care in the US

Health disparities are a prevalent issue that continues to affect health outcomes. In ophthalmology, these disparities affect eye care utilization increasing the burden of eye care disorders and vision impairment/loss. Various factors contribute to disparities in vision care. They include age, gender, socioeconomic status, geographic location, and race and ethnicity. These factors make it difficult for people affected by eye conditions to access care. Addressing these disparities can help to increase eye care utilization and improve patient outcomes. Some measures that can address these disparities and increase utilization are providing patient education, increasing insurance coverage, implementing community-based eye care programs, using teleophthalmology, providing transport services, providing reminder alerts, and creating community centres that are federally funded among others. This review seeks to identify measures that can help to address disparities in vision and eye care in the US. The review also identifies drivers of health disparities in vision health and how they affect the ability to access care.

Eye Care in Federally Qualified Health Centers

PurposeTo understand the availability of vision care provided within Federally Qualified Health Centers (FQHCs) in 2017 versus 2021, and to assess whether differences exist in neighborhood-level demographic factors and social risk factors (SRFs) between FQHCs based on the availability of eye care services. DesignSecondary data analysis of the Health Resources and Services Administration (HRSA) FQHC data and 2017-2021 American Community Survey neighborhood SRFs. ParticipantsFQHCs in 2017 and 2021. MethodsPatient and neighborhood characteristics for each SRF were summarized. Differences in FQHCs providing and not providing vision care were compared via Wilcoxon Mann–Whitney tests for continuous measures and chi-square tests for categorical measures. Logistic regression models were used to test the associations between neighborhood measures and FQHCs providing vision care, adjusted for patient characteristics. Main Outcome MeasuresOdds ratios (ORs) with 95% confidence intervals for neighborhood-level predictors of FQHCs providing vision care services. ResultsOverall, 28.5% of FQHCs (n=375/1318) provided vision care in 2017 vs. 32% (n=435/1362) in 2021 with some increases and decreases in both the number of FQHCs and those with and without vision services. Only 2.6% of people who accessed FQHC services received eye care in 2021. Among the 435 FQHCs that provided vision care in 2021, 27.1% (n=118) had added vision services between 2017 and 2021, 71.5% (n=311) had been offering vision services since at least 2017, and 1.4% were newly established. Logistic regression models demonstrated FQHCs providing vision care in 2021 were more likely to be in neighborhoods with higher percentage of Hispanic/Latino individuals (OR=1.08, 95% CI=1.02-1.14, p=0.0094), Medicaid-insured individuals (OR=1.08, 95% CI=1.02-1.14, p=0.0120), and no car households (OR=1.07, 95% CI=1.01-1.13, p=0.0142). However, FQHCs with vision care, compared to FQHCs without vision care, served a lower percentage of Hispanic/Latino individuals (27.2% vs. 33.9%, p=0.0007), Medicaid-insured patients (42.8% vs. 46.8%, p<0.0001), and patients living at/below 100% of the federal poverty line (61.3% vs. 66.3%, p<0.0001). ConclusionsVision care services are available at few FQHCs, localized to a few states. Expanding access to eye care at FQHCs would meet patients where they seek care to mitigate vision loss to underserved communities.

Continued care and provision of glasses are necessary to improve visual and academic outcomes in children: Experience from a cluster-randomized controlled trial of school-based vision screening

ObjectiveTo assess the effectiveness of a kindergarten vision screening program by randomly assigning schools to receive or not receive vision screening, then following up 1.5 years later.MethodsFifty high-needs elementary schools were randomly assigned to participate or not in a vision screening program for children in senior kindergarten (SK; age 5‒6 years). When the children were in Grade 2 (age 6‒7 years), vision screening was conducted at all 50 schools.ResultsContrary to expectations, screened and non-screened schools did not differ in the prevalence of suspected amblyopia in Grade 2 (8.6% vs. 7.5%, p = 0.10), nor prevalence of other visual problems such as astigmatism (45.1% vs. 47.1%, p = 0.51). There was also no difference between screened and non-screened schools in academic outcomes such as the proportion of children below grade level in reading (33% vs. 29%) or math (44% vs. 38%) (p = 0.86). However, more children were wearing glasses in screened than in non-screened schools (10.2% vs. 7.8%, p = 0.05), and more children reported their glasses as missing or broken (8.3% vs. 4.7%, p = 0.01), suggesting that SK screening had identified successfully those in need of glasses. Examination of individual results revealed that 72% of children diagnosed and treated for amblyopia in SK no longer had amblyopia in Grade 2.ConclusionThe prevalence of amblyopia and other visual problems was not reduced in Grade 2 by our SK vision screening program, perhaps because of poor treatment compliance and high attrition. The results suggest that a single screening intervention is insufficient to reduce visual problems among young children. However, the data from individuals with amblyopia suggest that continuing vision care and access to glasses benefits children, especially children from lower socioeconomic class.

Exploring Pediatric Vision Care: Insights from Five Years of Referral Cases in the UCI Eye Mobile and Implications of COVID-19.

To analyze referral rates, patient demographics, referral indications, and the impact of socioeconomic factors on ocular health from the University of California Irvine (UCI) Eye Mobile for Children, particularly during the coronavirus disease 2019 (COVID-19) pandemic. A retrospective chart review was performed on de-identified records of children examined on the UCI Eye Mobile. GraphPad Prism 10.0.0 and Python software were used for statistical analyses. In the academic years from 2018 to 2022, 3,619 children received comprehensive eye examinations on the UCI Eye Mobile. Among them, 76 were referred to a pediatric ophthalmologist. The majority of these children were Hispanic (72.6%, 54 of 74), followed by Asian (10.9%, 8 of 74). A significant proportion (82.9%, 63 of 76) attended school districts with median incomes below that of Orange County. Statistically significant differences were found in age (P = .001; pre-COVID: 3.98 ± 1.08 years vs COVID: 5.75 ± 2.92 years) and gender (P = .023; pre-COVID female: 31 of 41 vs COVID female: 15 of 32) between the pre-COVID and COVID years. Additionally, there were significant differences in the proportion of children with hyperopia with astigmatism between the pre-COVID and COVID years (P = .044; pre-COVID: 23 of 40 vs COVID: 12 of 35). The most common indications for ophthalmologist referrals were for strabismus evaluation/treatment (28.9%, 22 of 76), followed by abnormal cup-to-disc ratio (21.1%, 16 of 76). The study highlights the pivotal role of the UCI Eye Mobile for children in identifying ocular conditions needing referrals to subspecialty care. The majority of children needing these referrals attended schools in lower economic communities. Additionally, the COVID-19 pandemic appears to have influenced the demographic and clinical characteristics. [J Pediatr Ophthalmol Strabismus. 20XX:X(X):XXX-XXX.].

EXAMINING THE DECREASE IN SYMPTOMS IN PATIENTS WITH DACRYOCYSTORHINOSTOMY BOTH WITH AND WITHOUT SILICON INTUBATION A RANDOMIZED CONTROLLED TRIAL

Objective: To determine if dacryocystorhinostomy or silicon intubation is more effective in treating nasolacrimalduct obstructionStudy Design: A Randomized Controlled Trial StudyPlace and duration of study: This research was conducted over a six-month period, from October 9, 2021, to April 9,2022, at the Department of Clinical Ophthalmology, Khyber Girls’ Medical College, Hayatabad Medical Complex(HMC), Peshawar.Materials and Methods: The study comprised 446 patients with nasolacrimal duct blockage (NLDO). Eachpatient was split up into two cohorts. Group A had cryocystorhinostomy (DCR) with silicon intubation, whereasGroup B underwent DCR without intubation.Results: The average age of the sample was 35.1 + 9.2 years. The mean age of Group B was 35.2 + 9.1 years,whereas the mean age of Group A was 34.9 + 9.3 years (p 0.730). Group A consisted of 61.9% males and groupB had 56.5% males (p 0.248). The average number of days that symptoms persisted was 11 + 3.2 days in group Aand 10.4 + 2.9 days in group B (p 0.082). As determined by the overall remission of symptoms, group A’s efficacywas 79.4% at follow-up, whereas group B’s was 69.5% (p 0.017).Conclusion: For those with NLDO, silicon intubation significantly boosts the efficacy of DCR when compared toDCR without intubation.Key Words: Nasolacrimal duct obstruction, dacryocystorhinostomy, intubation, silicon, and efficacy.

Enhancing Vision Care through Psychological Assessment in Sub-Saharan Africa: An Overview

Enhancing Vision Care through Psychological Assessment in Sub-Saharan Africa: An Overview

Simulation-based training for intraoperative posterior capsule rupture management: an analysis of nontechnical skills development and the relationship between technical and nontechnical skills.

To analyse development of individual nontechnical skills (NTS) domains after undertaking a previously developed simulation-based training model and analyse the relationship between technical skills (TS) and NTS in ophthalmic surgery. The simulation-based training model involved a cataract surgery case complicated by intraoperative posterior capsule rupture. Cataract surgeons underwent the simulation twice, separated by a training intervention. Two blinded independent experts assessed participants' NTS using HUFOES, NOn-Technical Skills for Surgeons (NOTSS), and the OSATS global rating scale for TS. Paired t-tests assessed differences in individual NTS domains, with p < 0.05 indicating significance. The Pearson Product Moment Correlation Coefficient was used to assess the correlation between scores from each scoring system. All NTS domains within HUFOES and NOTSS demonstrated statistically significant improvements secondary to the training intervention. Positive correlations were demonstrated between HUFOES and OSATS scores in the pre- and post-training simulations, r = 0.870 (p < 0.001) and r = 0.861 (p < 0.001), respectively. Positive correlations were also demonstrated between NOTSS and OSATS scores in pre- and post-training simulations, r = 0.849 (p < 0.001) and r = 0.757 (p = 0.001), respectively. Positive correlations were demonstrated between HUFOES and NOTSS scores; r = 0.979 (p < 0.001) (n = 17) and r = 0.959 (p < 0.001) for pre- and post-training simulations, respectively. All NTS domains contained within HUFOES and NOTSS demonstrated significant increases following the completion of the simulation-based training model. Positive correlations exist between an ophthalmic surgeon's TS and NTS. This is the first study to report these findings within ophthalmic surgery.

Using Smartphones to Enhance Vision Screening in Rural Areas: Pilot Study.

While it is treatable, uncorrected refractive error is the number one cause of visual impairment worldwide. This eye condition alone, or together with ocular misalignment, can also cause amblyopia, which is also treatable if detected early but still occurs in about 4% of the population. Mass vision screening is the first and most critical step to address these issues, but due to limited resources, vision screening in many rural areas remains a major challenge. We aimed to pilot-test the feasibility of using smartphone apps to enhance vision screening in areas where access to eye care is limited. A vision screening program was piggybacked on a charity summer camp program in a rural county in Sichuan, China. A total of 73 fourth and fifth graders were tested for visual acuity using a standard eye chart and were then tested for refractive error and heterophoria using 2 smartphone apps (a refraction app and a strabismus app, respectively) by nonprofessional personnel. A total of 5 of 73 (6.8%, 95% CI 2.3%-15.3%) students were found to have visual acuity worse than 20/20 (logarithm of minimal angle of resolution [logMAR] 0) in at least one eye. Among the 5 students, 3 primarily had refractive error according to the refraction app. The other 2 students had manifest strabismus (one with 72-prism diopter [PD] esotropia and one with 33-PD exotropia) according to the strabismus app. Students without manifest strabismus were also measured for phoria using the strabismus app in cover/uncover mode. The median phoria was 0.0-PD (IQR 2.9-PD esophoria to 2.2-PD exophoria). The results from this vision screening study are consistent with findings from other population-based vision screening studies in which conventional tools were used by ophthalmic professionals. The smartphone apps are promising and have the potential to be used in mass vision screenings for identifying risk factors for amblyopia and for myopia control. The smartphone apps may have significant implications for the future of low-cost vision care, particularly in resource-constrained and geographically remote areas.

FREQUENCY OF CYSTOID MACULAR EDEMA ON OPTICAL COHERENCE TOMOGRAPHY IN TWO DIFFERENT TYPES OF CATARACT SURGERY

Cystoid macular edema (CME), also known as Irvine-Gass syndrome, has been recognized as a non-specific manifestation of various ocular conditions, with cataract surgery being a significant contributing factor. First reported by Sir Irvine in 1953 and further discussed by Sir Norton in 1966, CME following cataract surgery remains a topic of interest and concern in ophthalmology. The precise etiology of CME in post-cataract surgery patients remains elusive; however, it is widely accepted that post-surgical inflammation plays a pivotal role. To address this issue, we conducted a comparative study to assess the frequency of CME using spectral-domain optical coherence tomography (SD-OCT) in patients undergoing extracapsular cataract extraction (ECCE) versus phacoemulsification cataract surgeries. The study was conducted at the Department of Clinical Ophthalmology, Khyber Institute of Ophthalmic Medical Sciences; Medical Teaching Institute Hayatabad Medical Complex, Peshawar, over a period of 6 months. Utilizing a randomized controlled trial design and non-probability consecutive sampling, we determined a sample size of 70 patients, with 35 patients allocated to each group (Group A: ECCE, Group B: Phacoemulsification). The age of the participants ranged from 50 to 85 years, with a median of 60 years and a mean of 65±8 years. Our findings revealed that CME was observed in 11% of patients in Group A and 6% in Group B, indicating a lower frequency in post-operative cases. However, the difference in CME incidence between ECCE and phacoemulsification cases was not statistically significant. These results suggest that the risk of CME in post-operative cases may be influenced by various factors, including surgical technique and patient-specific variables. In conclusion, our study contributes to the understanding of CME following cataract surgery and underscores the importance of continued vigilance and further research in this area. Improved surgical techniques and perioperative management may help mitigate the risk of CME and enhance patient outcomes in the postoperative period.

Insights Into Eye Care Accessibility: Geospatial Distribution of Eye Care Providers and Socioeconomic Factors by ZIP Code.

In the United States, the ZIP Code has long been used to collect geospatial data revealing disparities in social determinants of health. This cross-sectional study examines the distribution of eye care access in association with local socioeconomic factors at a ZIP Code level. Data from the 2020 Centers of Medicare and Medicaid Services and American Community Survey were used to examine locations of 47,949 providers (17,631 ophthalmologists and 30,318 optometrists) and corresponding local socioeconomic variables (education, employment, and income). Multivariable zero-inflated negative binomial regression was used to model eye care provider count per capita in each ZIP Code area with socioeconomic factors as independent covariates. For every 1% increase in percentage of population over 25 years with a bachelor's degree or higher, the expected number of providers increases by 4.4% (incidence rate ratio [IRR] = 1.044; 95% confidence interval [CI], 1.041-1.046; P < 0.001). For every 1% increase in percentage unemployment, the expected number of providers decreases by 2.7% (IRR = 0.973; 95% CI, 0.964-0.983; P < 0.001). However, for every $1000 increase in median household income, the expected number of providers decreases by 1.6% (IRR = 0.984; 95% CI, 0.983-0.986; P < 0.001). Disparities in access exist in areas of lower employment and educational attainment, as both have positive correlations with eye care provider access. Conversely, areas of greater median household income have lower access to providers. This research contributes to a greater field studying social determinants of health and may inform public health strategies on allocation of providers to improve equitable access to vision care.

Клинический случай факоэмульсификации катаракты после термокератопластики в анамнезе

Purpose. To present a clinical case of cataract phacoemulsification in a patient with a thermokeratoplasty in anamnesis. Material and methods. Patient M., went to the clinic with complaints of decreased vision, “fog” in front of both eyes, especially in front of the right one. In the anamnesis 30 years ago, she had thermokeratoplasty for high degree hypermetropia (+8.00D) in both eyes. Due to the existing complaints and the presence of cataracts in both eyes, cataract phacoemulsification was performed with the implantation of toric IOLs in both eyes. Results. When evaluating the results in the longterm postoperative period (1 year after surgery), it was revealed that despite the difficulties that the surgeon faces when calculating intraocular lenses in patients after keratorefractive operations, we managed to achieve high visual acuity. Conclusions. The presented clinical case indicates that the measurement of the refractive power of the cornea using a modern scanning keratotopograph, the axial length of the eye using a noncontact biometer, the use of modern formulas for calculating the IOL, as well as the experience of an ophthalmic surgeon, allow achieving high functional results in the rehabilitation of patients with this pathology. Keywords: thermokeratoplasty, phacoemulsification of cataract, toric intraocular lens

Addressing Disparities in Vision Health and Eye Care in the US

Health disparities are a prevalent issue that continues to affect health outcomes. In ophthalmology, these disparities affect eye care utilization increasing the burden of eye care disorders and vision impairment/loss. Various factors contribute to disparities in vision care. They include age, gender, socioeconomic status, geographic location, and race and ethnicity. These factors make it difficult for people affected by eye conditions to access care. Addressing these disparities can help to increase eye care utilization and improve patient outcomes. Some measures that can address these disparities and increase utilization are providing patient education, increasing insurance coverage, implementing community-based eye care programs, using teleophthalmology, providing transport services, providing reminder alerts, and creating community centres that are federally funded among others. This review seeks to identify measures that can help to address disparities in vision and eye care in the US. The review also identifies drivers of health disparities in vision health and how they affect the ability to access care. Keywords: eye disorders, disparities, vision health, eye care, utilization

Proliferative diabetic retinopathy in severe stages: modern approaches to diagnosis and treatment (systematic review)

Diabetic retinopathy (DR) is a leading complication in patients with diabetes mellitus (DM). Because of the increase in the clinical effectiveness of treatment for diabetes, the life expectancy of patients has increased, which accordingly increases the risk of severe forms of DR (proliferative DR), which is one of the main causes of blindness and low vision in the working-age population. In the literature, the overall prevalence of DR and proliferative DR is up to 34.6% and 12.0%, respectively, whereas 25% of cases of vision loss associated with DR are caused by complications of proliferative DR. Colour fundus photography and optical coherence tomography are the most informative clinical diagnostic methods for DR. In severe stages of proliferative DR, the information content of the presented indicators can be significantly reduced because of insufficient visualisation of the patient’s fundus. Thus, the literature proposes qualitative criteria (specific and single indicators) based on an expert assessment of the condition of the fundus by an ophthalmic surgeon. The described approach has a fairly high diagnostic efficiency. Along with this, it appears relevant to study the ‘quality of life’ of a patient with symptoms of proliferative DR caused by the occurrence of characteristic manifestations of psychological distress (psychological and anxiety disorders and depression). In surgical terms, functional results notably improved after vitrectomy for proliferative DR in 49–83% of cases. Moreover, the proposed methods for conducting vitrectomy for patients with advanced stages of proliferative DR do not fully consider ophthalmological and somatic features, which requires the consideration of the surgical treatment of this contingent as a separate area of vitrectomy for improving ophthalmological ‘techniques’, drug support and choice of anaesthesia.

Low Vision Practice and Service Provision Among Optometrists in Ghana: A Nationwide Survey

ABSTRACT Purpose To characterize practice patterns of low vision services among Optometrists in Ghana. Methods The nationwide cross-sectional survey identified entities through the Ghana Optometrists Association (GOA) registry and utilized a semi-structured questionnaire to consolidate survey information that comprises practitioners’ demographics, available services, diagnostic equipment, barriers to service provision and utilization, and interventions. Results 300 Optometrists were identified, with 213 surveyed (71% response rate). About fifty percent (52.6%) were in private practice, and more than two-thirds (77%) did not provide low vision services. Most (≥70%) reported lack of assistive devices, and basic eye care examination kits as the main barriers to low vision service provision. Similarly, practitioners reported unawareness of the presence of low vision centres (76.1%), and high cost of low vision aids (75.1%) as the prime perceived barriers for patients to utilize low vision services. Continuous professional development and public education (89–90%) were suggested as interventions to improve the uptake of low vision services. After statistical adjustment, private facility type (Adjusted odds ratio [AOR] = 0.35, p = 0.010) and lack of basic eye examination kits (AOR = 0.32, p = 0.002) were significantly associated with reduced odds of low vision service provision. Conversely, ≥15 years of work experience (AOR = 6.37, p = 0.011) was significantly associated with increased odds of low vision service provision. Conclusions Overall, the results indicate inadequate low vision coverage and service delivery. Government policies must be directed towards equipping practitioners with equipment and subsidize patient cost of treatment to optimize low vision care.
