A Systematic Review of Ophthalmology Education in Medical Schools: The Global Decline.

TOPIC: This systematic review examined geographical and temporal trends in medical school ophthalmology education in relationship to course and student outcomes. CLINICAL RELEVANCE: Evidence suggesting a decline in ophthalmology teaching in medical schools is increasing, raising concern for the adequacy of eye knowledge across the rest of the medical profession. METHODS: Systematic review of Embase and SCOPUS, with inclusion of studies containing data on medical school ophthalmic course length; 1 or more outcome measures on student ophthalmology knowledge, skills, self-evaluation of knowledge or skills, or student course appraisal; or both. The systematic review was registered prospectively on the International Prospective Register of Systematic Reviews (identifier, CRD42022323865). Results were aggregated with outcome subgroup analysis and description in relationship to geographical and temporal trends. Descriptive statistics, including nonparametric correlations, were used to analyze data and trends. RESULTS: Systematic review yielded 4596 publication titles, of which 52 were included in the analysis, with data from 19 countries. Average course length ranged from 12.5 to 208.7 hours, with significant continental disparity among mean course lengths. Africa reported the longest average course length at 103.3 hours, and North America reported the shortest at 36.4 hours. On average, course lengths have been declining over the last 2 decades, from an average overall course length of 92.9 hours in the 2000s to 52.9 hours in the 2020s. Mean student self-evaluation of skills was 51.3%, and mean student self-evaluation of knowledge was 55.4%. Objective mean assessment mark of skills was 57.5% and that of knowledge was 71.7%, compared with an average pass mark of 66.7%. On average, 26.4% of students felt confident in their ophthalmology knowledge and 34.5% felt confident in their skills. DISCUSSION: Most evidence describes declining length of courses devoted to ophthalmology in the last 20 years, significant student dissatisfaction with courses and content, and suboptimal knowledge and confidence.

Endophthalmitis following intravitreal injections administered by junior medical officers in rural Western Australia.

BACKGROUND: Patients in rural Australia have limited access to intravitreal treatments due to a maldistribution of the ophthalmology workforce. To improve access, a novel outreach service model was implemented whereby junior medical staff administered intravitreal injections under a supervising ophthalmology consultant. This model involves outreach visits in hospitals, mobile clinics and a remote hub with intravitreal injections administered by junior doctors overseen by an ophthalmologist. The article explores the safety of this approach with respect to the rate of post-injection endophthalmitis. METHODS: A retrospective audit was conducted by the Lions Outback Vision outreach ophthalmology service from 2017 to mid-2023. The number of injections, locations, diagnoses, intravitreal agents used, designation of administering doctor and cases of endophthalmitis were reviewed. RESULTS: A 12 632 intravitreal injections were administered across 32 locations throughout rural Western Australia in the 6.5-year period. Three cases of endophthalmitis occurred representing a rate of 0.0237%. CONCLUSION: The rate of endophthalmitis in the outreach service is comparable to other centres. The outreach model with supervising ophthalmology consultant support in person or via telehealth and administration of injections by junior medical staff has improved access for underserved or marginalised populations.

Educators' consideration of learner motivation in ophthalmology education in medical school: Influences on teaching practice and course design.

BACKGROUND: Ophthalmology education in medical school has historically neglected the impact of autonomous motivation on student learning and wellbeing. This study aimed to understand ophthalmology educators' consideration and application of student motivation in ophthalmology medical education. MATERIAL AND METHODS: Lead ophthalmology educators from Australian and New Zealand medical schools participated in an online semi-structured in-depth interview. Interview transcripts were analysed using thematic analysis. Codes were generated and aligned into overarching themes. FINDINGS: Six educators participated in the study. Five main themes arose from the transcripts: the lack of explicit consideration of student motivation, implicit consideration of motivation in curriculum design and in teaching practices, the impact of innovation on motivation and the relationship between teacher and student motivation. Participants also commented on trends in ophthalmology education including generalists' confidence in managing ophthalmic disease, the role of fundoscopy in medical education and time pressure on ophthalmology in medical schools. CONCLUSION: There has only been an implicit instead of explicit consideration of motivation in ophthalmology education in medical school, which leaves an unfulfilled potential for teaching practices to impact the affective along with cognitive and metacognitive aspects of learning. This study highlights the need for motivation to be explicitly incorporated into the development of teaching practices and curriculum reform.

Intravitreal dexamethasone versus bevacizumab in Aboriginal and Torres Strait Islander patients with diabetic macular oedema: The OASIS study (a randomised control trial).

BACKGROUND: Frequent intravitreal anti-VEGF injections are impractical for many Aboriginal patients with diabetic macular oedema (DMO). The longer acting intravitreal dexamethasone implant (DEX-implant) is approved for DMO but has not been assessed in an Aboriginal population. METHODS: This was a prospective, multicentre, randomised, single-masked, non-inferiority clinical trial. Aboriginal adults from Western Australia with DMO were randomised to receive 3-monthly DEX-implant, or monthly intravitreal bevacizumab. The primary outcome was the change in best corrected visual acuity (BCVA) at 12 months. RESULTS: The final endpoint was analysed for 24 DEX-implant and 28 bevacizumab injection eyes. Mean BCVA improved by 4.0 letters (-0.08 LogMAR) in the DEX-implant group and worsened by 5.5 letters (0.11 LogMAR) in the bevacizumab group. Before adjusting for cataract surgery, the upper bound of the two-sided 90% CI for the DEX-implant was 3.5 letters (0.07 LogMAR), which met non-inferiority criteria. The BCVA of remote participants who received the DEX-implant improved by 5.5 letters (0.11 LogMAR), compared to an 18.5 letter (0.37 LogMAR) decline for bevacizumab (p = 0.04). The incidence of steroid-induced ocular hypertension for the DEX-implant was 33.3%. CONCLUSIONS: Before adjusting for the effect of cataract surgery, the DEX-implant was non-inferior to bevacizumab for treating DMO in Aboriginal participants. In remote participants, the DEX-implant surpassed non-inferiority to achieve superior outcomes to bevacizumab. The incidence of steroid-induced hypertension was comparable to that reported in non-Aboriginal populations. We provide guidelines for the judicious use of DEX-implant among Aboriginal people, and a framework for performing ophthalmic clinical trials in Aboriginal communities.

Gaming to improve vision: 21st century self-monitoring for patients with age-related macular degeneration.

IMPORTANCE: Improved vision self-monitoring tools are required for people at risk of neovascular complications from age related macular degeneration (AMD). BACKGROUND: to report the self-monitoring habits of participants with intermediate AMD using the Amsler grid chart, and the use of personal electronic devices and gameplay in this over 50 year old cohort. DESIGN: single-centre descriptive study carried out at the Centre for Eye Research (CERA), Melbourne, Australia. PARTICIPANTS: 140 participants over 50 years of age, with a diagnosis of intermediate AMD and best-corrected visual acuity (BCVA) of ≥6/12 in each eye. METHODS: structured questionnaire survey of participants who were enrolled in natural history of AMD studies at CERA. MAIN OUTCOME MEASURES: frequency of vision self-monitoring using the Amsler grid chart, and frequency of general use of personal electronic devices and gameplay. RESULTS: Of 140 participants with mean age of 70.5 years, 83.6% used an Amsler grid chart, but only 39.3% used it once per week. Most participants (91.4%) used one or more personal electronic devices. Of these, over half (54.7%) played games on them, among whom 39% played games once a day. Of participants aged 50-69 years, 92% (95%CI 85.1-98.9) were willing to play a game to monitor their vision, compared to 78% (95%CI 69.0-87.0) of those aged 70 years and older (P < 0.05). CONCLUSIONS AND RELEVANCE: a large proportion of AMD patients already use personal electronic devices. Gamification techniques are likely to increase compliance with self-monitoring, leading to earlier detection in the next generation of patients with neovascular AMD.

Increasing the impact of teleophthalmology in Australia: Analysis of structural and economic drivers in a state service.

PROBLEM: Despite its potential to improve service provision for country patients, teleophthalmology is currently underused in Australia. There is an associated lack of cost-effectiveness data for teleophthamology. DESIGN: Retrospective and prospective hospital-based clinical audits of 5456 patients; descriptive survey of available telehealth equipment in 129 regional facilities; cost calculations for teleophthalmology, patient transfers and outreach services. SETTING: Primary (optometry, general practice [GP], Aboriginal Medical Service [AMS]) and secondary (hospital) sites in regional Western Australia; a tertiary hospital in Perth. KEY MEASURES FOR IMPROVEMENT: Proportion of patients suitable for teleophthalmology; proportion of regional practices with telehealth technology; capital expenditure to equip regional practices for teleophthalmology; total savings from increased utilisation of teleophthalmology. STRATEGIES FOR CHANGE: Advocacy for funding, regulatory, training and infrastructure recommendations, in order to support efficient models of teleophthalmology. EFFECTS OF CHANGE: A total of 15% and 24% of urgent patient transfers and outreach consultations, respectively, were found to be suitable for teleophthalmology, equating to a potential total cost saving of $1.1 million/year. Capital expenditure required for basic telehealth equipment was negligible for optometrists, compared to $20 500 per GP/AMS practice. Successful advocacy led to funding, training and policy changes to support optometry-led teleophthalmology for country patients in Australia. LESSONS LEARNT: Public-private partnerships can result in significant cost-savings for the Australian health system. Targeted, evidence-based advocacy can inform government health reforms.

Describing the Eye Health of Newly Arrived Refugees in Adelaide, South Australia.

This study describes the eye health of newly arrived refugees attending a state-funded health service in Adelaide, South Australia, helping to address the paucity of data on the eye health of refugees. Patients attending the Refugee Health Service undergo comprehensive assessment by an on-site optometrist with accredited interpreters if they have eye symptoms, personal or family history of eye disease, or visual impairment (using World Health Organization definitions). A retrospective audit of this service was performed to obtain patient demographics, presenting best-corrected distance visual acuity (better-seeing eye), diagnoses, and management. In 2017-2018, 494 of the 1400 refugees attending the service underwent an optometry assessment (age range 1-86 years, mean age 33.1 ± 18.6 years, 53% female). Regions of origin included the Middle East (25%), Bhutan (24%), Afghanistan (22%), Myanmar (15%), and Africa (14%). Of the 124 cases of visual impairment, 78% resolved with corrective lenses and 11% were due to cataracts. Ophthalmology follow-up was required for 56 (11%) patients, mostly for cataracts (22 patients). Newly arrived refugees have high rates of visual impairment from refractive error and cataracts. Integration of optometry and state-based refugee health services may improve the timely detection and treatment of these conditions.

Self-determination theory in ophthalmology education: factors influencing autonomy, competence and relatedness in medical students.

BACKGROUND: The affective components of learning, including student motivation, has yet to be thoroughly investigated in undergraduate ophthalmology education. This study aims to use Self-Determination Theory (SDT) as a framework to describe the variations in student perceptions of motivation in studying ophthalmology through their satisfactions of autonomy, competence and relatedness, and to highlight factors that stimulate or hinder this. METHODS: Penultimate year medical students from a single tertiary educational institution undertaking a clinical placement in ophthalmology participated in in-depth interviews to explore factors affecting their perceptions of motivation in studying ophthalmology. Interviews were transcribed and analysed according to the principles of interpretive phenomenography through the theoretical framework of SDT. RESULTS: Of the 39 students invited, 10 agreed to participate. Variations in perceptions of experiences generated the outcome space. Participants experienced either amotivation, external locus extrinsic motivation, internal locus extrinsic motivation and intrinsic motivation (conceptions of the outcome space). This was described with respect to their satisfaction of autonomy, competence and relatedness (dimensions of the outcome space). Additionally, 21 factors that impacted on motivation were identified, of which five over-arching factors impacted all three basic psychological needs - guidance, growth mindset, assessment, curricular pressure and extracurricular pressure. CONCLUSIONS: The findings of this study provide a unique insight into the motivation of medical students studying ophthalmology. This provides an exciting opportunity for medical educators to address the affective aspect of learning.

Preoperative visual acuity among cataract surgery patients and countries' state of development: a global study.

OBJECTIVE: To describe the preoperative surgical case mix among patients undergoing cataract extraction and explore associations between case mix, country level of development (as measured by the Human Development Index, HDI) and cataract surgery rates (CSRs). METHODS: Ophthalmologists in 50 countries were invited to join the newly-established International Eye Research Network and asked to complete a web-based questionnaire about their eye hospitals. Those who complied received a data collection form for recording demographic and clinical data on 100 consecutive patients about to undergo cataract surgery. Countries were ranked into five HDI categories and multivariable regression was used to explore associations. FINDINGS: Ophthalmologists at 112 eye hospitals (54% of them nongovernmental) in 50 countries provided data on 11,048 cataract procedures over 9 months in 2008. Patients whose visual acuity (VA) before surgery was < 6/60 in the better eye comprised 47% of the total case mix in poorly developed countries and 1% in developed countries (P < 0.001). Overall, 72% of the eyes undergoing surgery had a VA < 6/60. Very low VA before cataract surgery was strongly associated with poor development at the country level and inversely associated with national CSR. CONCLUSION: The proportion of patients with very poor preoperative VA is a simple indicator that can be easily measured periodically to monitor progress in ophthalmological services. Additionally, the internet can be an effective tool for developing and supporting an ophthalmological research network capable of providing a global snapshot of service activity, particularly in developing countries.

Self-inflicted penetrating eye injuries using a razor blade: case report.

BACKGROUND: A 23 year old white male with a history of social and behavioural problems attempted to blind himself chemically, with alcohol, and mechanically, with a razor blade. METHODS: Observational case report of a patient who self-inflicted bilateral scleral lacerations with a razor blade, after losing his job. RESULTS: The patient sustained bilateral inferior scleral perforations, with hypotony and a right traumatic cataract. He received urgent surgical repair, and prophylactic antibiotics. There were no retinal breaks or detachments. He later underwent successful cataract surgery to the right eye. CONCLUSION: Self-inflicted ocular injury may be possible in non-psychotic patients, as a situational response to a life event. Urgent repair can completely restore vision in some cases. Referral for psychiatric counseling is mandatory.

Wii eye injury: self-inflicted globe rupture and vision loss in a 7-year-old boy from a video game accident.

The Nintendo Wii is a home video game console released in November 2006. It is distinguished by its Wii Remote, a wireless controller that can be used as a handheld pointing device. We report a self-inflicted penetrating eye injury, late retinal detachment, and vision loss in a 7-year-old boy resulting from the use of a Wii Remote. To our knowledge, this is the first reported case of severe ocular trauma from use of a wireless game controller.

Refractive error in Nigerian adults: prevalence, type, and spectacle coverage.

PURPOSE: To provide data on prevalence and types of refractive error and the spectacle-wearing rate among adults in Nigeria and the degree to which the need for distance correction could be met by off-the-shelf spectacles. METHODS: Multistage, stratified, cluster random sampling with probability proportional to size was used to identify a nationally representative sample of 15,027 persons aged ≥40 years. Distance vision was measured using a reduced logMAR tumbling-E chart. All participants underwent autorefraction, and those with presenting acuity of <6/12 in one or both eyes had their corrected acuity measured and underwent detailed clinical examination to determine the cause. RESULTS: Included in the survey were 13,599 (89.9%) of the 15,122 persons aged ≥40 years who were enumerated. Uncorrected refractive error was responsible for 77.9% of mild visual impairment (<6/12-6/18), 57.1% of moderate visual impairment (<6/18-6/60), 11.3% of severe visual impairment (<6/60-3/60), and 1.4% of blindness (<3/60). The crude prevalence of myopia (≤0.5 D) and high myopia (≤5.0 D) were 16.2% and 2.1%, respectively. Spectacles could improve the vision of 1279 (9.4%) and 882 (6.5%) participants at the 6/12 and 6/18 level, respectively, but only 3.4% and 4.4% of these individuals wore spectacles to the examination site. Approximately 2,140,000 adults in Nigeria would benefit from spectacles that improved their vision from <6/12 to ≥6/12. More than a third of the need could be met by low-cost, off-the-shelf spectacles. CONCLUSIONS: Uncorrected refractive errors are an important cause of visual impairment in Nigeria, and services must be dramatically improved to meet the need.

Prevalence and causes of severe visual impairment and blindness among children in the lorestan province of iran, using the key informant method.

PURPOSE: To estimate the prevalence and causes of severe visual impairment and blindness among children in Lorestan province of Iran, and to assess the feasibility of the Key Informant Method in this setting. METHODS: Potential cases were identified using the Key Informant Method, in 3 counties of Lorestan province during June through August 2008, and referred for examination. Causes of severe visual impairment/blindness were determined and categorized using standard World Health Organization methods. RESULTS: Of 123 children referred for examination, 27 children were confirmed to have severe visual impairment/blindness or blindness. The median age was11 years (interquartile range 6-13), and 59% were girls. After adjusting for non-attenders, the estimated prevalence of severe visual impairment/blindness was 0.04% (0.03-0.05). The main site of abnormality was retina (44%), followed by disorders of the whole eye (33%). The majority of causes had a hereditary etiology (70%), which was associated with a family history of blindness (P = 0.002). Potentially avoidable causes of severe visual impairment/blindness were found in 14 children (52%). Almost all children with severe visual impairment/blindness had a history of parental consanguinity (93%). CONCLUSIONS: Our findings suggest a moderate prevalence of childhood blindness in the Lorestan province of Iran, a high proportion of which may be avoidable, given improved access to ophthalmic and genetic counselling services in rural areas. The Key Informant Method is feasible in Iran; future research is discussed.
