Objectives: To describe the etiologies of binocular diplopia for patients presenting to the ophthalmologic emergency department of the Regional University Center Hospital (CHRU) of Tours., Methods: This is a retrospective study of the medical records of patients who presented with binocular diplopia in the ophthalmic emergency department of the CHRU of Tours between January 1st and December 31st, 2019. Binocular diplopia was classified as paralytic or non-paralytic according to the ocular motility examination., Results: One hundred twelve patients were included. The median age was 61 years. Internal referral from other hospital services represented 44.6% of the patients. On ophthalmological examination, 73.2% had paralytic diplopia, 13.4% non-paralytic diplopia and 13.4% normal examination. Neuroimaging was performed in 88.3% of cases, with 75.7% of patients receiving it on the same day. Oculomotor nerve palsy was the most frequent cause of diplopia in 58.9%, the majority represented by abducens nerve palsy (60.6%). The most frequent etiology of binocular diplopia was ischemic, with microvascular damage in 26.8% of cases and stroke in 10.7% of cases., Conclusion: Among patients assessed in an ophthalmological emergency department setting, one in ten patients had stroke. It is essential to inform patients of the urgent nature of ophthalmological evaluation in the case of acute binocular diplopia. Urgent neurovascular management is also mandatory and should be based on the clinical description provided by the ophthalmologist. Neuroimaging should be performed as soon as possible, based on the ophthalmologic and neurological findings., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

Introduction: E-learning is a pedagogic approach that relies on the use of electronic media and devices as tools to improve access to training, communication and interaction, facilitating the adoption of knowledge, skills and/or behaviors. Learning games offer a learning and training environment using entertaining elements from video games in a real-life scenario. The objective of this work is the conception of a learning game for training ophthalmic technician students., Methods: Design of a learning game, in collaboration with iLumens and the Dowino® corporation, allowing the performance of an orthoptic evaluation in a child without ocular pathology., Results: We developed the "Orthoptist Simulator" a learning game that faithfully reproduces an orthoptic box with necessary tools to carry out an orthoptic evaluation with ocular motility examination. The game offers learning, training and self-evaluation modes. It allows the student to evaluate a young patient, take a history and perform the 17 most frequently used orthoptic tests. The student thus creates a report of the results of these tests to be transmitted to the ophthalmologist who requested the workup., Conclusions: To our knowledge, we have set up the first learning game for the training of future ophthalmic technicians, which is an innovative educational tool and complementary to traditional training. This game could also be used to train ophthalmology residents in ocular motility examination. This new instrument will require future evaluation to determine its real impact on training., (Copyright © 2022. Published by Elsevier Masson SAS.)
