Methods: An online survey was sent to practicing ophthalmologists around the world through email, Whatsapp (TM) ListServ17.0 (TM) (for pediatric ophthalmologists), WeChat (TM) (China) and ophthalmology associations (Indonesia, Philippines, Ireland). All queries were collected and categorized. Responses to the queries were given according to the recommendations by the Ophthalmology association. Practices ability to deal with the COVID were also classified according to country and type of access to PPE. Statistical analyses of the association between these data and queries, where appropriate were carried out. Results: One thousand nine hundred sixteen ophthalmologists were invited to participate in a survey between April 10(th) and April 30(th), 2020 of which 1207 responded, which is a response rate of approximately 63%. The majority of respondents were from India, Indonesia, China, Singapore and the USA. Our study indicates a precipitous drop in surgical procedures with 46% (n = 538) ophthalmologists ceased to operate on their patients and almost 40% (n = 486) were doing less than 25% of their original number of surgeries. The intent to resume elective surgeries was a consideration in 41% (n = 495) after an evaluation of the situation and in consultation with professional bodies. More than 2/3 of the respondents (n = 703) made it a priority to use and mandate their patients to practice physical distancing, wearing masks, and hand dis-infection for protection to limit the spread of infection. Conclusion: This global survey provides a real-world assessment of diverse practices that were in various forms of "shut down mode" and circumstances with varying capabilities to deal with COVID. It is unprecedented that the collective wisdom for a curtailment of practice has had an enormous immediate and far reaching implications on the livelihoods of ophthalmologists, their staff, and their families. Nevertheless, ophthalmologists and their staff remain resilient and have adapted to these changes pragmatically.

Methods: Cross-sectional study of students who were taking online classes. In May 2020, the participants completed a Dry Eye Questionnaire (DEQ-5) and a self-report survey, which included demographics, medical history, information on the use of VDT and presence of VDT-related symptoms. Participants were classified as having mild/moderate (7-12) or severe (>12) DE symptoms based on their DEQ-5 score. The associations between severe DE symptoms and relevant factors were also evaluated. Results: The data of 1450 eligible students were analyzed. The mean age of the participants was 21.1 (2.7) years. 42.8% of the participants had mild/moderate DE symptoms, whereas 34.7% had severe symptoms. Associated factors for severe DE were female sex (OR = 2.57, CI [1.97-3.35]), allergic disease (OR = 1.63, CI [1.24-2.13]), previous dry eye diagnosis (OR = 13.49, CI [7.10-25.63]), keratoconus (OR = 5.56, CI [1.27-24.44], contact lens use (OR = 1.77, CI [1.24-2.53]) and duration of VDT use (OR = 1.02, CI [1.01-1.05]). Prior to the pandemic, the mean reported duration of VDT use was 9.8 (4.7) hours; this increased to 15.9 (5.8) hours during the online classes (p < .001). 80.6% of the participants reported a global increase in VDT-related symptoms. Conclusion: Students taking online classes had a high frequency of DE symptoms. They also reported a significant increase in VDT-related symptoms. DE should be considered as an emerging health problem among the young population, which is probably related to the recent changes in lifestyle.

Methods We conducted 20 focus groups with 105 parents and teachers at schools in Baltimore, MD, that participated in a SBVP. Facilitators used a semi-structured interview guide to discuss participants' perceptions of the SBVP. Focus groups were audio-recorded, transcribed, and coded using inductive thematic analysis. Results Participant perceptions fell into three categories: benefits of school-based eye care, limitations of school-based eye care, and observation of impact. The majority of participants had positive comments about the programme; benefits included convenience (location, time, and cost), the comprehensive nature of the programme, the quality of the eyeglasses and ability to receive replacements, and a positive screening/exam experience. Limitations of programme impact were related to communication and organisation, the time to receive the glasses, missed instructional time, and uncertainty about screenings. Observations of impact included academic and classroom improvements, as well as visual and other health improvements. Conclusion Parents and teachers reported mostly positive perceptions regarding the SBVP. Their appreciation for the convenience underscores that location, cost, time, and comprehensive services are crucial aspects for implementing a successful programme. To maximize impact, programs must also implement robust communication campaigns that integrate into the schools' workflow to help parents and teachers stay engaged in the process from start to finish.

Methods : This prospective, multicentre, observational study used data extracted from the eye injury registry for tertiary teaching hospitals in Daegu, South Korea, between August 2016 and July 2018. Children aged < 16 years were classified as infants, pre-schoolers, school children, and adolescents based on their age group. Results : This study included 502 patients; most eye injuries occurred among boys (n = 349, 69.5%) and school children (n = 168, 33.5%). Unstructured play (n = 268, 53.4%) was the most common cause of eye injury, followed by sports (n = 69, 13.7%) and home activities (n = 52, 10.4%). Among adolescent boys, eye injuries were mostly caused by sports activities (n = 49, 37.7%), including soccer and basketball. Only 1 out of 69 children wore protective eyewear during sports activities. Eye injuries occurred most often in school (n = 63, 41.2%) during adolescence and at home (n = 270, 53.8%) in most other age groups. Conclusion : Eye injuries were more common in boys. Boys and girls had relatively higher proportion of eye injuries during sports and home activities, respectively. In infants to school children, eye injuries mainly occurred at home and by unstructured play, whereas in adolescents, they mostly occurred at school and during sports activities. To prevent eye injuries sustained during sports in adolescents, wearing personal protective equipment during high-risk exercise in schools or sports facilities is recommended.

    查看更多>>摘要：Purpose: To determine incidence, risk factors for, and outcomes of dropped nucleus (DN) during cataract surgery. Methods: This is a matched case-control study at the Aravind Eye Hospital in Madurai, India. Out of 184 consecutive DN cases, 171 were included. The case immediately preceding the DN case by the same surgeon served as matched concurrent control. The proportion of cataract surgeries with DN was calculated with a 95% confidence interval (CI). Conditional logistic regression was used to generate odds ratios for potential risk factors. Results: Among 415,487 consecutive cataract surgeries, incidence risk of DN was 0.044% [95% CI 0.038%, 0.051%], or 0.44 per 1,000 surgeries in 52 months. Significant preoperative risk factors were posterior polar cataract (adjusted odds ratio [aOR] 21.73, p = .003); suspected loose zonules (aOR 8.85, p < .001); older age (aOR 1.57, p = .001); and presence of diabetes mellitus (aOR 1.79, p = .03). Associated intraoperative complications included zonular dialysis (OR 34.49, p < .001), vitreous disturbance (OR 193.36, p < .001), and posterior capsule rent (OR 384.39, p < .001). Phacoemulsification and manual small incision cataract surgery did not significantly differ in DN incidence. DN most commonly occurred during nucleus removal (35.1%) or during/immediately following hydrodissection (24.0%). Visual outcomes of DN were worse than controls on average, but 51.9% achieved visual acuity 20/40 or better at 1 month. Conclusions: DN occurred rarely, with low absolute risk even when a strong risk factor was present. Nearly all cases followed posterior capsular rent or zonular dialysis, usually with observed vitreous loss. In spite of increased risk of postoperative complications in the DN group, the majority achieved favorable results.

    查看更多>>摘要：Purpose: To analyze differences between rates of complex and routine cataract surgery based on demographics and social determinants of health (SDOH) at the community level. Methods: Data from adults ages 18 to 84 relevant to cataract surgery billing codes were extracted from the 2017 Florida Ambulatory Surgery dataset from the Agency for Healthcare Research and Quality merged with SDOH measures from the American Community Survey. A multivariable logistic regression model was used to determine associations between complex cataract surgery and SDOH according to patient ZIP code. Outcomes were reported as odds ratios (OR) with 95% confidence intervals (CI). Results: A total of 171,754 and 11,340 patients received routine and complex cataract surgeries, respectively; females received the majority of routine surgeries (58.87%); most common age group (79.11%) was from 65 to 84 years. Male (odds ratio [OR] 2.034; p < 0.0001) and black patients (OR 1.998; p < 0.0001) more likely received complex surgery. Compared to Medicare patients, patients insured with Medicaid (OR 2.058; p < 0.0001), private insurance (OR 1.057; p = 0.0182), or self-pay (OR 1.570; p < 0.0001) were more likely to receive a complex surgery. ZIP codes with higher adult poverty (OR 2.614; p < 0.001) were more likely complex surgery patients, whereas those with higher rates of high school attendance (OR 0.487; p = 0.0193) and home occupancy (OR 0.704; p = 0.0047) were less likely to be complex. Conclusions: Selected patient- and community-level factors including being male, Black, Asian, Hispanic, non-Medicare, or within lower education, higher poverty ZIP codes were associated with a higher likelihood of receiving complex cataract surgery.

    查看更多>>摘要：Background: Screening for diabetic eye disease (DED) and general diabetes care is often separate, which leads to delays and low adherence to DED screening recommendations. Thus, we assessed the feasibility, achieved image quality, and possible barriers of telemedical DED screening in a point-of-care general practice setting and the accuracy of an automated algorithm for detection of DED. Methods: Patients with diabetes were recruited at general practices. Retinal images were acquired using a non-mydriatic camera (CenterVue, Italy) by medical assistants. Images were quality assessed and double graded by two graders. All images were also graded automatically using a commercially available artificial intelligence (AI) algorithm (EyeArt version 2.1.0, Eyenuk Inc.). Results: A total of 75 patients (147 eyes; mean age 69 years, 96% type 2 diabetes) were included. Most of the patients (51; 68%) preferred DED screening at the general practice, but only twenty-four (32%) were willing to pay for this service. Images of 63 patients (84%) were determined to be evaluable, and DED was diagnosed in 6 patients (8.0%). The algorithm's positive/negative predictive values (95% confidence interval) were 0.80 (0.28-0.99)/1.00 (0.92-1.00) and 0.75 (0.19-0.99)/0.98 (0.88-1.00) for detection of any DED and referral-warranted DED, respectively. Overall, the number of referrals was 18 (24%) for manual telemedical assessment and 31 (41%) for the artificial intelligence (AI) algorithm, resulting in a relative increase of referrals by 72% when using AI. Conclusions: Our study shows that achieved overall image quality in a telemedical GP-based DED screening was sufficient and that it would be accepted by medical assistants and patients in most cases. However, good image quality and integration into existing workflow remain challenging. Based on these findings, a larger-scale implementation study is warranted.

    查看更多>>摘要：Purpose: The G-ROP model was proposed to improve the retinopathy of prematurity (ROP) screening efficiency. It is based on gestational age, birth weight and postnatal weight gain. The current study aimed to validate the G-ROP model's ability to predict ROP in cohorts of premature infants from Egypt and the United Kingdom (UK). Methods: We retrospectively reviewed the records of preterm infants born between 1st of January and 30th of June 2018 with a known outcome for ROP screening and regular weight measurements until day 39 after birth. We applied the G-ROP model to the study group and calculated the sensitivity of the model for detecting Early Treatment of ROP (ETROP) study type 1 ROP and for any ROP and calculated the reduction of the number of infants requiring ROP screening by the model application. Results: We applied the G-ROP model on 605 infants (504 from Egypt and 101 from the UK). The model successfully predicted all type 1 ROP cases (100% sensitivity) in both cohorts (95% confidence interval [CI], 91.1-100% in the Egyptian cohort and 65.5-100% in the UK cohort). The model reduced the number of infants requiring screening by 14.1% in the Egyptian cohort and 21.8% in the UK cohort. Conclusions: The G-ROP model was successfully validated for detecting type 1 ROP and in both cohorts from Egypt and the UK.

    查看更多>>摘要：Purpose: To evaluate the association between obstructive sleep apnea (OSA) and central serous chorioretinopathy (CSCR). Methods: A retrospective, cohort, longitudinal study was conducted using the national health insurance database in Taiwan between 1996 and 2013. Patients diagnosed with OSA were enrolled after exclusion, and a control group with similar age, gender, and major systemic co-morbidities were included in a 1:1 ratio by propensity score matching. The primary outcome is the occurrence of CSCR, and patients with CSCR were categorized via severity for further analysis. The percentage of incident CSCR in the OSA group and control groups and the adjusted hazard ratios (aHR) of CSCR were determined by Cox proportional hazard regression. Results: There were 13,084 patients enrolled in both the OSA group and control groups, respectively. The total event of CSCR was 50 (0.4%) in the OSA group and 25 (0.2%) in the control group (P < .001). Moreover, the OSA group has an increased aHR of 1.9 (P = .012) for developing CSCR. In the subgroup analysis, patients with OSA aged from 30 to 39 and 50 to 59 demonstrated higher risk of developing CSCR compared to the control group, and the presence of OSA would lead to a higher incidence of mild CSCR (all P < .05). Conclusions: OSA patients aged from 30 to 39 and 50 to 59 have a higher risk of developing CSCR, while the severity of CSCR will not be worsen by OSA.

    查看更多>>摘要：Purpose: To investigate the prevalence of dual sensory impairment (DSI), its associated factors and relationship with health-related quality of life (HR-QoL) in residential care facilities (RCF) in Singapore. Methods: This was a cross-sectional study of 123 residents aged >= 40 years from six RCFs, conducted between 2016 and 2018. DSI was defined as concomitant presenting visual acuity (better-eye) >0.3 logarithm of the minimum angle of resolution and a pure-tone air conduction threshold (better-ear) >40 dB HL in any of the four tested frequencies (500, 1000, 2000 and 4000 Hz). HR-QoL was quantified using the EuroQol five-dimension questionnaire. Multivariable Poisson regression was used to determine the associated factors of DSI. Multivariable linear regression was used to determine the association between DSI and HR-QoL adjusted for traditional confounders. Results: Of the 123 residents (age [mean +/- standard deviation] 75.3 +/- 10.8 years; 56.9% male), 97 (78.9%[95% confidence interval(CI):71.6%, 86.1%]) had DSI, with 110 (98.2%) not on follow-up care for their sensory disabilities. In multivariable models, male gender (prevalence ratio(PR) [95%CI] = 1.3[1.1, 1.6]), older age (per 10-year increase (1.2[1.1, 1.3])), education <= 6 years (1.3[1.1, 1.7]) and the presence of cataract (1.3[1.0, 1.7]) were independently associated with DSI. DSI was independently associated with a substantial worsening in HR-QoL (beta = -0.61; 95%CI: -0.76, -0.45; p < .001). Conclusions: DSI affects four in five residential care residents and is substantially associated with reductions in HR-QoL in these residents. Our finding highlights an urgent need for the implementation of routine vision and hearing screening and follow-up care for residents living in these facilities.
