Improving the training abilities of ophthalmic educators: the Ophthalmology Foundation’s initiatives

Our goal as medical educators is for our students to learn what they need to know and competently perform ophthalmic procedures.In addition,the students need to have good communication skills and behave professionally and ethically(1,2).Most medical educators are not taught how to teach but rather learn by role-modeling their mentors.This can be good or bad depending on the mentor!In addition,the amount of knowledge and numbers of surgical procedures is ever increasing and yet,in most countries,the amount of time to train and become competent is not changing.Thus,our goal of creating competent ophthalmologists is ever more challenging.

Flipped classroom approach to global outreach:cross-cultural teaching of horizontal strabismus to Chinese ophthalmology residents

AIM:To evaluate the flipped classroom model for teaching horizontal strabismus didactics in an ophthalmology residency program in China as part of a visiting professorship from the United States.METHODS:Residents from an ophthalmology residency program in China were invited to participate in flipped classroom sessions taught by an experienced American ophthalmology faculty in 2018.Residents were instructed to watch a pre-class video lecture prior to the in-class-casebased activity.Content tests(5 Ophthalmic Knowledge Assessment Program style questions)and surveys were administered before and after the classroom sessions(100%response rate).These results were compared to that of an American cohort who were taught the same content.RESULTS:The Chinese cohort of 12 residents preferred the flipped classroom to the traditional classroom at higher rates than the American cohort of 40 residents(92%vs 55%,P=0.04)and felt that all ophthalmology topics would be appropriate for the flipped classroom teaching style(P-values between 0.008 and<0.001).In both Chinese and American cohorts,we found that the exotropia curriculum saw a small but significant improvement in performance following the flipped classroom session(P=0.025 for Chinese residents;P=0.001 for US residents),whereas scores in both groups for the esotropia course did not significantly improve.CONCLUSION:This is the first study to evaluate the flipped classroom model implemented by a visiting ophthalmology professor in a global outreach setting.The flipped classroom sessions are viewed favorably by the Chinese residents relative to the US cohort with a modest impact on knowledge.Decreased in-person interpreter requirement and increased student engagement make this model valuable in cross-cultural visiting professorship settings.Finally,the flipped classroom may lend itself well to a virtual format to prevent the transmission of COVID-19,although such a format requires further study.

Stem Cell Ophthalmology Treatment Study(SCOTS) for retinal and optic nerve diseases: a case report of improvement in relapsing auto-immune optic neuropathy

We present the results from a patient with relapsing optic neuropathy treated within the Stem Cell Ophthalmology Treatment Study （SCOTS）. SCOTS is an Institutional Review Board ap- proved clinical trial and has become the largest ophthalmology stem cell study registered at the National Institutes of Health to date （www.clinicaltrials.gov Identifier NCT 01920867）. SCOTS utilizes autologous bone marrow-derived stem cells （BMSCs） for treatment of retinal and optic nerve diseases. Pre-treatment and post-treatment comprehensive eye exams of a 54 year old female patient were performed both at the Florida Study Center, USA and at The Eye Center of Columbus, USA. As a consequence of a relapsing optic neuritis, the patient＇s previously normal visual acuity decreased to between 20/350 and 20/400 in the right eye and to 20/70 in the left eye. Significant visual field loss developed bilaterally. The patient underwent a right eye vitrectomy with injection of BMSCs into the optic nerve of the right eyeand retrobulbar, subtenon and in- travitreal injection of BMSCs in the left eye. At 15 months after SCOTS treatment, the patient＇s visual acuity had improved to 20/150 in the right eye and 20/20 in the left eye. Bilateral visual fields improved markedly. Both macular thickness and fast retinal nerve fiber layer thickness were maximally improved at 3 and 6 months after SCOTS treatment. The patient also reduced her mycophenylate dose from 1,500 mg per day to 500 mg per day and required no steroid pulse therapy during the 15-month follow up.

Ophthalmology simulation for undergraduate and postgraduate clinical education

This is a review education paper on the current ophthalmology simulators utilized worldwide for undergraduate and postgraduate training. At present, various simulators such as the EYE Exam Simulator （Kyoto Kagaku Co. Ltd., Kyoto, Japan）, Eyesi direct ophthalmoscope simulator （VRmagic, GmbH, Mannheim, Germany）, Eyesi indirect ophthalmoscope simulator （VRmagic, GmbH, Mannheim, Germany） and Eyesi cataract simulators （VRmagic, GmbH, Mannheim, Germany）. These simulators are thought to be able to reduce the initial learning curve for the ophthalmology training but further research will need to be conducted to assess the effectiveness of the simulation-assisted ophthalmology training. Future research will be of great value to assess the medical students and residents responses and performance regarding the usefulness of the individual eye simulator.

Teleophthalmology: a strategy for timely diagnosis of sight-threatening diabetic retinopathy in primary care, Concepción, Chile

AIM: To estimate the prevalence of diabetic retinopathy(DR) in a diabetic population of the public health system. METHODS: This non-experimental, descriptive and crosssectional study, with no direct control over the variables analysed, was carried out by the Telemedicine Unit of the University of Concepción(TELMED) and the Family Health Centers(CESFAM) of the Health Service Concepción, Chile, among a population of 7382 diabetic patients of the public health system, from October 2014 to June 2015. Two digital images for each patient’s eyes were obtained and uploaded to the TELMED tele-ophthalmology platform. The images were remotely evaluated by a retina expert ophthalmologist for diagnosis. Treatment and a referral(if required) were recommended, and an individualised report for each patient was sent to the place of origin.RESULTS: The prevalence of DR in this study was 14.9%. Of these, 48.7% had mild non-proliferative DR(NPDR), 30.8% moderate NPDR, 15.9% severe NPDR, and 4.6% proliferative DR. Of the patients with DR, 17.8% were referred for fluorescein angiography, 4.3% for panretinal photocoagulation, 1.2% for vitrectomy, and 0.4% for cataract surgery.CONCLUSION: The use of telemedicine allowed an increased screening coverage for DR in diabetic patients. The different types of DR were detected in a timely manner, decreasing waiting times due to the lack of specialists in ophthalmology in the public health system.

Application of artificial intelligence in ophthalmology

Artificial intelligence is a general term that means to accomplish a task mainly by a computer, with the least human beings participation, and it is widely accepted as the invention of robots. With the development of this new technology, artificial intelligence has been one of the most influential information technology revolutions. We searched these English-language studies relative to ophthalmology published on PubMed and Springer databases. The application of artificial intelligence in ophthalmology mainly concentrates on the diseases with a high incidence, such as diabetic retinopathy, agerelated macular degeneration, glaucoma, retinopathy of prematurity, age-related or congenital cataract and few with retinal vein occlusion. According to the above studies, we conclude that the sensitivity of detection and accuracy for proliferative diabetic retinopathy ranged from 75% to 91.7%, for non-proliferative diabetic retinopathy ranged from 75% to 94.7%, for age-related macular degeneration it ranged from 75% to 100%, for retinopathy of prematurity ranged over 95%, for retinal vein occlusion just one study reported ranged over 97%, for glaucoma ranged 63.7% to 93.1%, and for cataract it achieved a more than 70% similarity against clinical grading.
