Kalaw FGP, Tavakoli K, Baxter SL. Evaluation of Publications from the American Academy of Ophthalmology: A 5-Year Analysis of Ophthalmology Literature. OPHTHALMOLOGY SCIENCE 2023; 3:100395. [PMID: 38025157 PMCID: PMC10630667 DOI: 10.1016/j.xops.2023.100395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/21/2023] [Accepted: 09/05/2023] [Indexed: 12/01/2023]
Abstract
Objective To analyze recent publications in Ophthalmology, the journal of the American Academy of Ophthalmology. Design Retrospective review of published articles. Participants No human participants were involved in the study. Methods Articles published in Ophthalmology from January 2018 to December 2022 were reviewed and analyzed. Main Outcome Measures Research and review articles were included and analyzed per the following: total number of published articles based on related subspecialty area, level of evidence using the modified Oxford level of evidence, number of citations, number of listed authors, gender of the corresponding author, country of affiliation of the corresponding and contributing author(s), and involvement of consortium(s), group(s), or committee(s). Results A total of 965 articles were included. The mean (standard deviation) number of authors per article was 8.6 (5.7) and the majority of corresponding authors were male (665, 70.7%). The greatest number of published articles were related to retina (296, 30.7%) followed by glaucoma (172, 17.8%). The greatest number of Preferred Practice Pattern guidelines were also related to retina (7/24, 29.1%), followed by cornea/dry eye syndrome/external disease (6/24, 25%). Retina (77) had the most level 1 evidence, glaucoma (30) for level 2 evidence, and retina for levels 3 (69) and 4 (65). There were 223 articles contributed by consortia/groups/committees, with most from retina (73, 32.7%) followed by glaucoma (40, 17.9%). The mean number of citations per subspecialty article was highest in retina (45.8/article), followed by uveitis (31.7/article). The United States had the greatest number of affiliated corresponding authors (544, 56.4%), followed by the United Kingdom (68, 7.0%). There were 357 (37.0%) articles with coauthors affiliated outside the corresponding author's country of affiliation, although with a downward trend over the most recent 5-year period. There has been an increasing trend in the number of authors and consortia/group/committee involvement in publications. Conclusions Although team science and collaborations have increased recently, ongoing efforts to diversify individuals, groups, and subspecialties may be needed. Financial Disclosures Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

Geographic Atrophy Management Consensus (GA-MAC): a Delphi panel study on identification, diagnosis and treatment. BMJ Open Ophthalmol 2023; 8:e001395. [PMID: 37857560 PMCID: PMC10603481 DOI: 10.1136/bmjophth-2023-001395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 10/03/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND/AIMS With a paradigm shift in geographic atrophy (GA) treatments now available, establishing consensus on the identification and diagnosis of the disease along with considerations for management of patients with GA will assist eye care professionals (ECP) in their day-to-day practices, leading to improved patient outcomes. METHODS A modified Delphi panel process (Geographic Atrophy Management Consensus) consisting of three total surveys and one virtual live meeting held between survey 2 and survey 3. Data were collected from July to October 2022. Participants included expert members of the eye care community that have demonstrated outstanding leadership among peers: a steering committee with three ECPs and a 15-member panel divided between five optometrists, five comprehensive ophthalmologists and five retina specialists. Consensus on statements related to the management of patients with GA was calculated using the RAND/UCLA Appropriateness Method. RESULTS At the conclusion of the third survey, consensus was reached on 91% of the 77 statements. Critical consensus topics include: (1) optical coherence tomography as the favoured method to diagnose and monitor GA, (2) preferred practice patterns regarding referral of patients to retina specialists and (3) treatment criteria given the advent of emerging therapeutics for GA. CONCLUSIONS Generating awareness of early signs of disease development, progression and identifying the best tools to evaluate GA establishes ideal management and referral strategies. Given the paradigm shift in GA management driven by approved therapies, coupled with the fact that the disease is progressive resulting in devastating vision loss, these strategies are critical to ensure best overall outcomes.

Patel AJ, Vanner EA, Chou B, Sridhar J. Prevalence of Visual Impairment and Availability of Eye Care Providers in Florida. Am J Ophthalmol 2023; 253:215-223. [PMID: 37269971 DOI: 10.1016/j.ajo.2023.05.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 05/17/2023] [Accepted: 05/24/2023] [Indexed: 06/05/2023]
Abstract
PURPOSE To determine the association between prevalence of visual impairment (VI) and density of eye care providers in Florida counties. DESIGN Cross-sectional study. METHODS Population-based study included ophthalmologist members of the American Academy of Ophthalmology, licensed optometrists, and respondents of the 2015-2020 American Community Survey (ACS) administered by the US Census Bureau. The number of ophthalmologists collected from the American Academy of Ophthalmology member directory and the number of optometrists collected from the Florida Department of Health License registry were compared with prevalence of VI in each county as reported by ACS 2020 5-year estimates. Median age, mean income, race, and percent uninsured of each county were collected from ACS 2020 5-year estimates. Main outcome measures included the number of eye care providers and prevalence of VI per Florida county. RESULTS Eye care provider density and mean income of each county were negatively correlated with VI prevalence. Counties with zero eye care providers had significantly higher prevalence of VI per 100 000 residents than those with at least 1 eye care provider. While adjusting for mean income, for every increase in 1 eye care provider per 100 000 people, there was an expected decrease in VI prevalence by 31.15 ± 14.58 people per 100 000 residents. For every increase in mean county income by $1000, there was an expected mean ± SE decrease in prevalence of VI by 24.02 ± 9.90 people per 100 000 people. CONCLUSIONS Increased eye care provider density and mean county income are associated with lower prevalence of VI in Florida counties. Further studies may elucidate the cause for this relationship and solutions to decrease VI prevalence.

Deemer AD, Goldstein JE, Ramulu PY. Approaching rehabilitation in patients with advanced glaucoma. Eye (Lond) 2023; 37:1993-2006. [PMID: 36526861 PMCID: PMC10333291 DOI: 10.1038/s41433-022-02303-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 09/12/2021] [Accepted: 09/21/2021] [Indexed: 12/23/2022] Open
Abstract
Vision loss from advanced glaucoma is currently irreversible and impairs functional visual ability to effectively perform everyday tasks in a number of distinct functional domains. Vision rehabilitation strategies have been demonstrated to be effective in low vision populations and should be utilized in persons with advanced glaucoma to reduce disability and improve quality of life. Initial challenges to rehabilitation include an incomplete understanding of vision rehabilitation by the physician and patient, motivation to integrate rehabilitation into the plan of care, and availability of suitable providers to deliver this care. Physicians, working with well-trained vision rehabilitation providers can maximize function in important visual domains customized to the patient based on their needs, specific complaints, severity/pattern of visual damage, and comorbidities. Potential rehabilitative strategies to be considered for reading impairment include spectacle correction, visual assistive equipment, and sensory substitution, while potential strategies to facilitate driving in those deemed safe to do so include refractive correction, lens design, building confidence, restriction of driving to safer conditions, and avoiding situations where cognitive load is high. Mobility is frequently disrupted in advanced glaucoma, and can be addressed through careful distance refraction, behavior modification, home modification, mobility aids, walking assistance (i.e., sighted guide techniques), and smartphone/wearable technologies. Visual motor complaints are best addressed through optimization of lighting/contrast, sensory substitution, IADL training, and education. Special rehabilitative concerns may arise in children, where plans must be coordinated with schools, and working adults, where patients should be aware of their rights to accommodations to facilitate specific job tasks.

Abstract
OBJECTIVE Predicting the impact of neovascular age-related macular degeneration (nAMD) service disruption on visual outcomes following national lockdown in the UK to contain SARS-CoV-2. METHODS AND ANALYSIS This retrospective cohort study includes deidentified data from 2229 UK patients from the INSIGHT Health Data Research digital hub. We forecasted the number of treatment-naïve nAMD patients requiring anti-vascular endothelial growth factor (anti-VEGF) initiation during UK lockdown (16 March 2020 through 31 July 2020) at Moorfields Eye Hospital (MEH) and University Hospitals Birmingham (UHB). Best-measured visual acuity (VA) changes without anti-VEGF therapy were predicted using post hoc analysis of Minimally Classic/Occult Trial of the Anti-VEGF Antibody Ranibizumab in the Treatment of Neovascular AMD trial sham-control arm data (n=238). RESULTS At our centres, 376 patients were predicted to require anti-VEGF initiation during lockdown (MEH: 325; UHB: 51). Without treatment, mean VA was projected to decline after 12 months. The proportion of eyes in the MEH cohort predicted to maintain the key positive visual outcome of ≥70 ETDRS letters (Snellen equivalent 6/12) fell from 25.5% at baseline to 5.8% at 12 months (UHB: 9.8%-7.8%). Similarly, eyes with VA <25 ETDRS letters (6/96) were predicted to increase from 4.3% to 14.2% at MEH (UHB: 5.9%-7.8%) after 12 months without treatment. CONCLUSIONS Here, we demonstrate how combining data from a recently founded national digital health data repository with historical industry-funded clinical trial data can enhance predictive modelling in nAMD. The demonstrated detrimental effects of prolonged treatment delay should incentivise healthcare providers to support nAMD patients accessing care in safe environments.

Graefes Arch Clin Exp Ophthalmol 2023; 261:1743-1755. [PMID: 36633669 DOI: 10.1007/s00417-022-05972-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 10/31/2022] [Accepted: 12/30/2022] [Indexed: 01/13/2023] Open
Abstract
INTRODUCTION Developments in image processing techniques and display technology have led to the emergence of augmented reality (AR) and virtual reality (VR)-based low vision devices (LVDs). However, their promise and limitations in low vision rehabilitation are poorly understood. The objective of this systematic review is to appraise the application of AR/VR LVDs aimed at visual field expansion and visual acuity improvement in low vision rehabilitation. METHODS A systematic search of the literature was performed using MEDLINE, Embase, PsychInfo, HealthStar, and National Library of Medicine (PubMed) from inception to March 6, 2022. Articles were eligible if they included an AR or VR LVD tested on a sample of individuals with low vision and provided visual outcomes such as visual acuity, visual fields, and object recognition. RESULTS Of the 652 articles identified, 16 studies comprising 382 individuals with a mean age of 52.17 (SD = 18.30) years, and with heterogeneous low vision etiologies (i.e., glaucoma, age-related macular degeneration, retinitis pigmentosa) were included in this systematic review. Most articles used AR (53%), VR (40%), and one article used both AR and VR. The main visual outcomes evaluated were visual fields (67%), visual acuity (65%), and contrast sensitivity (27%). Various visual enhancement techniques were employed including variable magnification using digital zoom (67%), contrast enhancements (53%), and minification (27%). AR LVDs were reported to expand the visual field from threefold to ninefold. On average, individuals using AR/VR LVDs experienced an improved in visual acuity from 0.9 to 0.2 logMAR. Ten articles were classified as high or moderate risk of bias. CONCLUSION AR/VR LVDs were found to afford visual field expansion and visual acuity improvement in low vision populations. Even though the results of this review are promising, the lack of controlled studies with well-defined populations, use of small, convenience samples, and incomplete reporting of inclusion and exclusion criteria among included studies makes it challenging to judge the true impact of these devices. Future studies should address these limitations and compare various AR/LVDs to determine what is the ideal LVD type and vision enhancement combination based on the user's level of visual ability and lifestyle.

Abstract
SIGNIFICANCE We assessed the number of referrals for low vision (LV) services to determine if establishing an LV program at a large academic medical center impacted referral rates. Visual acuity (VA), referral outcome, location, and specialty were examined as factors that could impact referrals. PURPOSE This study aimed to identify gaps in the referral process to LV services. METHODS Electronic medical records of patients were reviewed to ascertain the referral rate among those who qualified for services, both before (2014 to 2016) and after (2017 to 2019) the establishment of an LV program. The medical records were further subdivided into two categories based on VA in the better-seeing eye: 20/70 to 20/200 and 20/200 to worse vision. RESULTS A total of 2014 patient records with VA qualifying for LV services were reviewed. The proportion of patients who had a VA of 20/70 to 20/200 inclusive in their better eye was 91.7%. A majority (89.8%) of patients with VA of 20/70 to 20/200 and 74.4% of patients with VA worse than 20/200 were never referred. Before establishing an LV program, only 2.2% of patients with VA of 20/70 to 20/200 were referred for services on their first visit, which improved to 8% after the program was established (odds ratio [OR], 3.88; 95% confidence interval [CI], 2.37 to 6.33; P < .001). Also, before the program's establishment, 12.5% of patients with VA worse than 20/200 were referred on their first visit, which increased to 31.9% after the program's establishment (OR, 3.29; 95% CI, 1.50 to 7.19; P = .002). Patients with VA worse than 20/200 were more likely to be referred (before: OR, 6.34 [95% CI, 3.03 to 13.28; P < .001]; after: OR, 5.38 [95% CI, 3.09 to 9.37; P < .001]). Our data also showed that 10.3% of patients in this study declined referral to LV services. CONCLUSIONS Referral rates to LV services are low among patients who qualify. The establishment of an LV program at the medical center significantly increased referral rates. However, more improvement is necessary to connect patients to LV services.

Abstract
Traditional Persian medicine (TPM) is one of the richest medical schools in the world, which has nurtured valuable books. From Ibn Sina's law to Heravi's successful medicinal facts, all emphasize the treatment of various diseases, especially eye diseases based on herbal medicines, as well as their prevention. In this study, by reviewing the authoritative books of Traditional Persian Medicine, we are looking for medicinal plants so that they can be used in the treatment of glaucoma or glaucoma. the purpose of this study is not to express the complete cure of glaucoma, but this article seeks to classify plants that from the perspective of Traditional Persian Medicine can be used as complementary medicine alongside conventional medical treatments. Methods and Materials: This is a summative qualitative content analysis that focused on Traditional Persian Medicine (TPM) texts from 2th to 13th AH centuries. Literature was searched during centuries 4th to 13th AH, and after described of glaucoma, extracting and classifying plants. Results: The scholars of TPM have opinions in the field of recognizing, describing and treating eye diseases and defining practical words. In almost all books of general Persian PM, the diagnosis and treatment of eye diseases have been discussed. Glaucoma in Traditional Persian Medicine is called “black water”. Conclusion: Unlike other medical schools in the world, in addition to treating diseases, Persian medicine has a strong recommendation to prevent the occurrence of disease and also to strengthen the body's visual powers by using 6 principles of maintaining health along with herbal medicines"

Abstract
Despite effective vision rehabilitation (VR) interventions, no gold standard model of care delivery has been established. The institution of the South East Ontario Vision Rehabilitation Service (SOVRS) introduced a centralized intake, an occupational therapist as a systems navigator, and improved communication pathways between low vision services in order to optimize regional VR care. The aim of this study is to compare the SOVRS model of VR to a traditional, hospital-based pre-SOVRS-implementation model using referral data. A single-site (Vision Rehabilitation Clinic at Kingston Health Sciences Center), retrospective medical chart review was performed. Data were gathered from the electronic medical records of patients who received a low vision assessment at the pre-SOVRS-implementation clinic (2017) and the SOVRS clinics (2019). A total of 245 charts were reviewed over the two study periods. There were no significant differences in the age, gender, or diagnoses causing vision loss between 2017 and 2019. One hundred nine incoming referrals were received in 2017, with 136 in 2019, representing a 25% increase in incoming referrals ( p < .001). The proportion of incoming referrals from non-ophthalmologists rose from 3.7% in 2017 to 31.9% in 2019 ( p < .001). The number of outgoing referrals also increased significantly, from 113 outgoing referrals in 2017 to 259 in 2019 ( p < .001), equivalent to a mean of 1.04 ± 0.68 (± standard deviation) outgoing referrals per incoming referral in 2017 and 1.90 ± 0.97 outgoing referrals per incoming referral in 2019. Outgoing service referrals also diversified significantly in 2019 ( p < .001), with more referrals to services such as VR health service organizations and community services. The SOVRS model was able to increase both the quantity and diversity of incoming and outgoing referrals by adopting several key strategies during its development. By expanding referrals, SOVRS increased the services available to patients and enabled a larger population to receive VR care.

Abstract
Low-vision rehabilitation (LVR) has significant benefit in improving the quality of life of visually impaired patients. However, these services are highly underutilized in ophthalmology practices. A quality improvement study was performed to investigate barriers to LVR services for patients at the University of Texas Medical Branch (UTMB) between 2010 and 2020. Low vision was defined as the best corrected visual acuity of 20/70 or worse in the better-seeing eye or a visual field less than 20 degrees. Potential subjects were screened (n = 577) from the electronic medical record using International Classification of Disease (ICD) codes for legal blindness, impaired vision, and low vision. Chart review identified 190 subjects who met criteria for low-vision analysis. Patients who received LVR referrals to attend at least one LVR service visit from the eligible subjects were contacted for participation in phone interviews regarding their LVR experience. Practicing eye care providers (ECPs) at UTMB completed a questionnaire to capture their referral patterns. Of the eligible subjects, 64% were referred to LVR services by ECPs. Reported patient barriers included mental health issues (76%), denial of need for low-vision aid (71%), poor physical health (67%), lack of transportation (57.1%), and lack of referrals (36%). EPCs reported patient's overall health (67%), older age (44%), lack of social support (44%), poor cognitive function (44%), and low likelihood of follow-up (44%) as barriers to referring patients to LVR. This study identified several modifiable barriers that can be addressed to access LVR services for low-vision patients. Changing referral patterns, eliminating variations in referral criteria, and increasing patient awareness and knowledge of LVR resources may tremendously improve the quality of life of low-vision patients.

Cortical Visual Impairment in Childhood: 'Blindsight' and the Sprague Effect Revisited. Brain Sci 2021; 11:brainsci11101279. [PMID: 34679344 PMCID: PMC8533908 DOI: 10.3390/brainsci11101279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 09/14/2021] [Accepted: 09/24/2021] [Indexed: 11/29/2022] Open
Abstract
The paper discusses and provides support for diverse processes of brain plasticity in visual function after damage in infancy and childhood in comparison with injury that occurs in the adult brain. We provide support and description of neuroplastic mechanisms in childhood that do not seemingly exist in the same way in the adult brain. Examples include the ability to foster the development of thalamocortical connectivities that can circumvent the lesion and reach their cortical destination in the occipital cortex as the developing brain is more efficient in building new connections. Supporting this claim is the fact that in those with central visual field defects we can note that the extrastriatal visual connectivities are greater when a lesion occurs earlier in life as opposed to in the neurologically mature adult. The result is a significantly more optimized system of visual and spatial exploration within the ‘blind’ field of view. The discussion is provided within the context of “blindsight” and the “Sprague Effect”.

Abstract
Purpose TO assess perceptions and implications of COVID-19 infection across the spectrum of individuals with visually impairment (VI) and those with normal sight. Design Prospective cross-sectional comparative study. Methods Setting: institutional. Patients: 232 patients and their caregivers. Four groups were created based on better eye characteristics: blind (best-corrected distance visual acuity [BCDVA] <3/60 or visual field <10 central degrees); severe VI (BCDVA ≤3/60 to <6/60; vertical cup-to-disc ratio ≥0.85 or neuroretinal rim width ≤0.1); moderate VI (BCDVA ≤6/60 to <6/18); or no or mild VI (controls: BCDVA ≥6/18) based on International Classification of Diseases-10 criteria and Foster and Quigley's consensus definition of glaucoma. Procedure: telephone questionnaires. Main outcome measures: differences in perceptions and implications of COVID-19 infection across various levels of VI. Caregiver perceptions were a secondary outcome measure. Results Surveys were completed by 232 participants, with 58 participants in each VI group. Mean age was 58.9 ± 13.2 years old. Greater degrees of VI were associated with older age (P = .008) and lower education level (P = .046). Blind participants more commonly perceived vision as a risk factor for contracting COVID-19 (P = .045), were concerned about access to health care (P <.001), obtained news through word of mouth (P <.001), and less commonly wore masks (P = .003). Controls more commonly performed frequent handwashing (P = .001), were aware of telemedicine (P = .029), and had fewer concerns about social interactions (P = .020) than groups with substantial VI. All caregivers reported more frequent patient care since the COVID-19 pandemic began. Conclusions The pandemic might have had a disproportionate impact on the visually impaired, and evidence-based assessments of COVID-19 health outcomes in this population are warranted.

Evaluating Reading Performance in Different Preferred Retinal Loci in Persian-Speaking Patients with Age-Related Macular Degeneration. J Curr Ophthalmol 2021; 33:48-55. [PMID: 34084957 PMCID: PMC8102939 DOI: 10.4103/joco.joco_192_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 06/26/2020] [Accepted: 08/20/2020] [Indexed: 11/04/2022] Open
Abstract
Purpose: To evaluate reading performance in different preferred retinal loci (PRLs) using a Persian version of a Minnesota Low Vision Reading (MNREAD) chart in Persian-speaking patients with age-related macular degeneration (AMD). Methods: In this cross-sectional study, 35 patients with AMD were assessed. The reading performance was investigated by the MNREAD chart without using low vision aids. The location of PRL was determined monocularly using an MP1 microperimeter (Nidek Technologies, Padua, Italy). The anatomical location of the fovea was determined using optical coherence tomography (OCT). Images were taken with the MP1 microperimeter, and Spectralis HRA-OCT device was processed using graphic software to determine the location of the PRL on the retina. Results: Thirty-five patients (51 eyes) with a mean age of 73.8 ± 7.7 years (range, 54–88 years) were assessed. Mean best corrected distance visual acuity (logMAR) was 0.65 ± 0.35 (range, 0.2–1.3). Mean levels of reading acuity (RA) (P = 0.009) and critical print size (CPS) (P = 0.015) were significantly different in different locations of PRL. Average scores of maximum reading speed (MRS) (P = 0.058) and reading accessibility index (ACC) (P = 0.058) were not statistically significant in different locations of PRL. There was a positive correlation between PRL-fovea distance and RA (P < 0.001, r = 0.591) and CPS (P < 0.001, r = 0.614). Significant negative correlations were observed between PRL-fovea distance and MRS (P < 0.001, r = −0.519) and ACC (P < 0.001, r = −0.545). Conclusions: This study provides evidence for differences in the reading performance of Persian-speaking patients with AMD in different PRL locations. The average scores of all reading indices obtained in the right-field PRL are lower than those in other areas and are highly correlated with the PRL-fovea distance.

Abstract
OBJECTIVE To develop and evaluate novel word embeddings (WEs) specific to ophthalmology, using text corpora from published literature and electronic health records (EHR). MATERIALS AND METHODS We trained ophthalmology-specific WEs using 121,740 PubMed abstracts and 89,282 EHR notes using word2vec continuous bag-of-words architecture. PubMed and EHR WEs were compared to general domain GloVe WEs and general biomedical domain BioWordVec embeddings using a novel ophthalmology-domain-specific 200-question analogy test and prediction of prognosis in 5547 low vision patients using EHR notes as inputs to a deep learning model. RESULTS We found that many words representing important ophthalmic concepts in the EHR were missing from the general domain GloVe vocabulary, but covered in the ophthalmology abstract corpus. On ophthalmology analogy testing, PubMed WEs scored 95.0 %, outperforming EHR (86.0 %) and GloVe (91.0 %) but less than BioWordVec (99.5 %). On predicting low vision prognosis, PubMed and EHR WEs resulted in similar AUROC (0.830; 0.826), outperforming GloVe (0.778) and BioWordVec (0.784). CONCLUSION We found that using ophthalmology domain-specific WEs improved performance in ophthalmology-related clinical prediction compared to general WEs. Deep learning models using clinical notes as inputs can predict the prognosis of visually impaired patients. This work provides a framework to improve predictive models using domain-specific WEs.

Abstract
Nordic and alpine skiing-related visual tasks such as identifying hill contours, slope characteristics, and snow conditions increase demands on contrast processing and other visual functions. Prospective observational studies were conducted to assess the relationships between skiing performance and a broad range of visual functions in nordic and alpine skiers with vision impairments. The study hypothesized that contrast sensitivity (CS), visual acuity (VA), and visual field (VF) would be predictive of skiing performance. Binocular static VA, CS, light sensitivity, glare sensitivity, glare recovery, dynamic VA, translational and radial motion perception, and VF were assessed in elite Para nordic (n = 26) and Para alpine (n = 15) skiers. Skiing performance was assessed based on skiers’ raw race times. Performance on the visual function tests was compared with skiing performances using Kendall’s correlations (with and without Bonferroni–Holm corrections) and linear multivariable regressions (p < 0.05 considered significant). None of the vision variables were significantly correlated with performance in Para nordic or Para alpine skiing after Bonferroni–Holm corrections were applied. Before applying the corrections, VF extent (ρ = -0.37, p = 0.011), and static VA (ρ = 0.26, p = 0.066) demonstrated the strongest correlations with Para nordic skiing performance; in Para alpine skiing, static VA and CS demonstrated the strongest correlations with downhill (static VA: ρ = 0.54, p = 0.046, CS: ρ = -0.50, p = 0.06), super G (static VA: ρ = 0.50, p = 0.007, CS: ρ = -0.51, p = 0.017), and giant slalom (static VA: ρ = 0.57, p = 0.01, CS: ρ = -0.46, p = 0.017) performance. Dynamic VA and VF were significantly associated with downhill (ρ = 0.593, p = 0.04) and slalom (ρ = -0.49, p = 0.013) performances, respectively. Static VA was a significant predictor of giant slalom [(F(3,11) = 24.71, p < 0.001), and R of 0.87], super G [(F(3,9) = 17.34, p = 0.002), and R of 0.85], and slalom [(F(3,11) = 11.8, p = 0.002), and R of 0.80] performance, but CS and VF were not. Interestingly, static VA and CS were highly correlated in both Para nordic (ρ = -0.60, p < 0.001) and Para alpine (ρ = -0.80, p < 0.001) skiers. Of the vision variables, only static VA and VF were associated with skiing performance and should be included as the in Para nordic and Para alpine classifications. The strong correlations between static VA and CS in these skiers with vision impairment may have masked relationships between CS and skiing performance.

Abstract
PURPOSE In this study, we describe common demographic and clinical characteristics of the glaucoma patient population attending vision rehabilitation. DESIGN Cross-sectional study. PARTICIPANTS Patients attending a hospital-based vision rehabilitation center with a primary ocular diagnosis of glaucoma. METHODS Participants' charts were retrospectively reviewed. Data extracted from medical records included demographics, referring physician, ocular history, glaucoma diagnosis, past ocular surgery, intraocular pressure, optic nerve findings, results of a functional intake assessing activities of daily living, depression, visual hallucinations, best-corrected visual acuity (BCVA), mean deviation (MD) scores on visual field testing, and log contrast sensitivity (CS). MAIN OUTCOME MEASURES Participant demographic information, ocular history, self-reported difficulty with activities of daily living, depression, visual hallucinations, BCVA, visual field, and CS. RESULTS The mean age of patients in this study was 77 years and ranged from 8 to 103 years. Ninety percent of patients were referred to vision rehabilitation by an ophthalmologist. Median BCVA was 20/50. Fifty-five percent of patients were functionally monocular, and for all patients, there was a median 9-line difference in BCVA between eyes. Median MD score was -13.95 decibels (dB). Median CS was 1.05. Patients reported having the greatest difficulty with reading (88%), writing (72%), and mobility (67%). Seventy-eight percent of patients stopped driving, and 12% reported difficulty driving. Among those experiencing depression, there was a 4:1 ratio of depressed patients having difficulty with mobility. One-third of patients experienced visual hallucinations. CONCLUSIONS Most glaucoma patients attending vision rehabilitation are not legally blind, but many are functionally monocular. This may cause greater difficulty performing functions that require the use of binocularity. Increasing the referral of younger glaucoma patients to vision rehabilitation may help patients learn to cope with the loss of visual function that occurs over time.

Abstract
PURPOSE To evaluate the outcomes of a 4-point scleral-fixated foldable Akreos AO60 intraocular lens (IOL) insertion using Gore-Tex suture performed by trainees under supervision of a single attending surgeon. METHODS Retrospective chart review for 53 eyes of 50 patients whose surgery was performed by trainees under supervision of a single surgeon between 2015 and 2018 at a tertiary care hospital (Johns Hopkins Wilmer Eye Institute, Baltimore, MD). Indications for surgery, preoperative risk factors, and intraoperative techniques were analyzed. Outcome measures included final best-corrected visual acuity (BCVA), change in BCVA, difference between expected and final spherical equivalent (SE), and postoperative complications. RESULTS Mean patient age was 62.8 years (range 26.9 to 88.4). The most common indication for surgery was IOL dislocation (59.6%) due to trauma in 21 cases (40.4%) and pseudoexfoliation in 6 (11.5%). Combined pars plana vitrectomy was performed simultaneously in 46 cases (88.5%). Mean BCVA improved from 20/100 to 20/40 (p < 0.001). The difference between expected and final SE was within 1.0 D in 28 cases (53.8%). Postoperative hypotony occurred in 12 eyes (21.2%) on day 1; all were resolved at last follow-up. Postoperative cystoid macular edema (CME) occurred in 20 cases (38.5%); 11 (21.2%) persisted through last follow-up. CONCLUSION Scleral-fixation of Akreos AO60 IOL in absence of capsular support can be performed by trainees under supervision and results in effective visual rehabilitation. Postoperative CME occurred at a higher rate than previously reported in the literature. Future studies should assess the rates of postoperative complications amongst different techniques of secondary IOL fixation performed by trainees to determine which is the safest.

Abstract
Introduction: Management of low vision in pediatric patients with greater result can affect their quality of life than in adult low vision patients.. Retinopathy of Prematurity is the main cause of blindness in children. A case study highlights the tertiary prevention (low vision examination and management) in a 5 year old boy with ROP related blindness to optimize his remaining visual capacity by using optical and non optical aids that support daily activity and educational learning.Case Report: A 5 year old boy with ROP related blindness visited to the low vision clinic after receiving the several treatments for ROP before. His visual acuities were light perception in the right eye and hand movement in the left eye using his current spectacle correction. He had anti VEGF bevacizumab intravitreal injection, vitrectomy and complicated cataract extraction history on the left eye. He wasdifficult to learn and read numbers and alphabets caused by visual impairment.Discussion : Upon evaluation by assessment low vision method, his distance visual acuity in the left eye was improved significantly up to 3/40 on LEA Acuity chart with +14.00D. His near vision became 10 M at 30 cm of reading distance (without near correction) and 4 M at 13 cm improved with +3.00 D by spectacle. The non optical aid devices as reading task were also suggested to improove continuous reading text without difficulty.Conclusion: ROP blindness can be preventable if appropriate, adequate and accessible screening programmes are available. Unfortunately, even with the current screening guidelines and recommended treatment of ROP, many babies suffer from blindness by this disease each year. Low vision assessment and management in pediatric patient with visual impairmentaccording to children’s need can optimize the recent visual capability of low vision patient and give self care daily activity and educational learning.

Abstract
INTRODUCTION A low-vision assessment (LVA) is central to developing a vision rehabilitation plan. However, access to LVAs is often limited by the quantity and geographic distribution of low-vision providers, as well as patient-centred transportation challenges. A tablet-based LVA tool kit, delivered virtually, has the potential to overcome many of these barriers. The purpose of this research was to validate a key component of the tablet-based tool kit - a commercially available iPad visual acuity (VA) test (Eye Chart Pro) iPad app - in a low-vision population. METHODS Participants with low vision (n = 26) and those who were normally sighted (n = 25) underwent VA testing with both the iPad VA test application and the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. The VA data were compared using a t-test, linear regression and Bland-Altman analysis. RESULTS There was no significant difference in the mean absolute difference in VA (log of minimum angle of resolution (logMAR)=0.11; p = 0.82). Eye Chart Pro and Standard ETDRS Chart measures were also not significantly different (p = 0.98). However, there were significant differences between test methods in the low-vision group and the normally sighted group (p > 0.0001 and p = 0.007, respectively). The Bland-Altman analysis showed a mean bias (difference) of -0.0005 logMAR between methods, and 95% limits of agreement of 0.298 and -0.299 logMAR. DISCUSSION The ETDRS chart function on the Eye Chart Pro application can reliably measure VA across a range, from normally sighted patients to those with low vision.

Abstract
INTRODUCTION A low-vision assessment (LVA) is critical in developing a vision rehabilitation plan. A remotely delivered LVA that replicates a standard in-clinic assessment may bridge the gap for patients not accessing care due to the limited quantity and distribution of low-vision providers. Within an LVA, an accurate and consistent assessment of refraction error is an essential component. No system has currently been validated for the purposes of a remote LVA. The purpose of this study was to validate a commercially available portable refraction approach in a low-vision population. METHODS Low-vision patients (n = 26) or normally sighted patients (n = 25) underwent a refraction assessment using the Adaptica® 2WIN autorefractor, adaptor scope (Kaleidos) and VisionFit phoropter portable refraction devices, as well as a standard autorefractor (Huvitz) and phoropter (Haag-Streit). Refraction data between systems and populations were compared using intraclass correlations. Bland-Altman plots were used to assess the differences between devices. RESULTS Spherical equivalent values were found to be reproducible between standard and experimental autorefraction devices (intraclass correlation coefficient (ICC) > 0.8) in both low-vision and normally sighted groups. Similarly, manifest refraction was highly consistent (ICC > 0.8) between devices in all groups. The Bland-Altman plots showed clinically acceptable mean differences of 0.701 between autorefraction methods and -0.116 between manifest refraction methods. DISCUSSION The 2WIN/VisionFit system can reliably generate refraction values across a spectrum of errors in normally sighted and visually impaired people, and would be feasible to deliver remotely.

Abstract
PURPOSE The aim of the study was to determine the functional concerns of patients with different clinical and demographic characteristics seeking low vision care in South India. DESIGN Cross-sectional clinic-based survey. METHODS Consecutive new patients evaluated by the low vision service at Aravind Eye Care System (AECS), Madurai, India, India from September 2016 to March 2017 were recruited. Clinical and sociodemographic data were collected and participants underwent a semistructured survey to determine vision-related functional concerns. Analyses were conducted to determine associations with functional concerns. This study was approved by the AECS Institutional Review Board and all participants provided informed consent. RESULTS The study included 419 participants (mean age 42.0 years, 65.2% male). Retinal dystrophy (35.8%) and acquired retinal disease (22.0%) were the most common diagnoses. The most frequently cited functional concerns were reading (37.7%), mobility (19.9%), and facial identification (13.8%). The number of functional concerns did not vary by diagnosis, age, sex, education, occupation, or presenting visual acuity (P > 0.05). Participants with retinal dystrophy were more likely to cite problems with night vision (P < .001). Age was significantly associated with greater difficulty recognizing faces [odds ratio (OR) = 1.20, 95% confidence interval (CI) = 1.01-1.43] and less night vision difficulty (OR = 0.75, 95% CI = 0.60-1.00). Worse presenting visual acuity was significantly associated with reporting a mobility problem (OR = 2.87, 95% CI = 2.09-3.93). CONCLUSIONS This study supports the expansion of low vision services in India targeted to common functional concerns including reading, mobility, and facial identification. However, results do not support the use of ocular diagnosis for this purpose.

Abstract
Vision impairment is an important general health issue that imposes many costs on governments and the health system every year. Despite the decline in infectious eye diseases, which has reduced the vision impairment and blindness over the past two decades, vision impairment is still a major health problem in some parts of the world. In traditional medicine books, visual weakness is referred to as "any disturbance in the act of seeing ". Many medicinal herbs have been mentioned in books of Traditional Iranian medicine (TIM) for the management of vision impairment. The aim of this study is to review the medicinal plants mentioned in TIM, which are considered effective for the treatment of vision impairment or its enhancement. In this library-based study, medicinal plants effective in the treatment of vision impairment were searched using 6 valid sources of traditional medicine, including Makhzan ol-Adawiya, The Canon of Medicine, Tuhfat al-Momenin, Al-Abniyah An Haqaiq al-adwiya, Al-Shamil Fi al-Sana'at al-tebiyah, and Ekhtiarate Badiee. This was done in 10 steps (finding keywords, searching for resources, preparing a single list, finding synonyms, classifying, reviewing, extracting plants from compositions, summarizing, scoring and sorting based on the obtained score). A total of 89 medicinal plants were extracted, most of which had a hot and dry temperament. Based on the obtained score, 12 plants got the highest scores (10 and above). The extracted plants can be the basis for further clinical studies to make new effective drugs for the prevention and treatment of vision impairment.

Abstract
Importance The prevalence of irreversible vision impairment in the United States is expected to increase by 2050. Vision rehabilitation is the primary treatment option. Clinical trials have established its efficacy in improving quality of life. Yet studies indicate that patients experience many barriers to accessing low-vision care. Objectives To examine the rate of referral for low-vision rehabilitation services by resident and attending ophthalmologists for adults with irreversible vision impairment and to assess the knowledge, attitudes, and beliefs of patients about vision rehabilitation. Design, Setting, and Participants Cross-sectional study with enrollment from June 20, 2016, to January 31, 2017, of 143 adults 18 years or older seen in a publicly funded, comprehensive eye clinic in Jefferson County, Alabama, and having 1 or both eyes with irreversible vision impairment (visual acuity was defined as 20/60 or worse) per the electronic health record. Exposures Demographic characteristics; patient questionnaire on knowledge, attitudes, and beliefs about vision rehabilitation; general cognitive status (Short Orientation-Memory-Concentration test); depressive symptoms (Patient Health Questionnaire-9); health literacy (Rapid Estimate of Adult Literacy in Medicine, Revised [REALM-R]); and self-reported difficulty in everyday activities. Main Outcomes and Measures Proportion of patients with irreversible vision impairment who were referred by ophthalmologists to low-vision rehabilitation services per the electronic health record. Results Of 143 patients enrolled with irreversible vision impairment in 1 or both eyes, the mean (SD) age was 55.4 (11.1) years and 68 (47.6%) were women. Most patients were African American (123 [86.0%]), uninsured (88 [61.5%]), and unemployed (92 [64.3%]); on average, they had normal cognitive status, minor depressive symptoms, and limited health literacy. As noted in the electronic health record, the rate of referral for low-vision rehabilitation services was 11.4% for patients with irreversible bilateral vision impairment (4 of 35 patients) and 1.9% for those with unilateral impairment (2 of 108). Most patients with bilateral (31 of 34 [91.2%]) and unilateral (90 of 97 [92.8%]) impairment indicated that they were bothered by their vision impairment, and most reported difficulty with reading (33 of 34 patients [97.1%] who were bilaterally impaired vs 85 of 104 [81.7%] who were unilaterally impaired). Conclusions and Relevance Results of this study suggest a need to better educate ophthalmologists and residents in ophthalmology about referrals to low-vision rehabilitation services for patients with irreversible vision impairment.

Abstract
Introduction The aim of this study is to describe the barriers and facilitators to accessing low vision rehabilitation services in Massachusetts, USA, and determine differences between communities with and without existing low vision rehabilitation services for older adults with visual impairment. Method A sample of older adults with visual impairment ( n = 64) from both communities participated in the study. Barriers and facilitators to accessing the services were explored through focus groups and prioritized during one-on-one interviews, which allowed for comparison between communities. Results Twelve themes were identified: (a) bureaucracy and funding (public policy); (b) public awareness and stigma (community); (c) services available, knowledge of providers, care coordination, transportation (organizational); (d) people and lack of awareness of family/friends (interpersonal); and (e) income, health status, knowledge, self-advocacy, and time (individual). Conclusion This study provides insights into the perceived barriers and facilitators of accessing low vision rehabilitation services for older adults with vision impairment living in Massachusetts, USA. Key findings indicate the need for improved awareness of these services at the provider and consumer level, coordinated care, increased education on the efficacy of occupational therapy low vision rehabilitation services, client-centered care provided when the client is ready to accept services, and service provision that addresses sociodemographic factors.
