PurposeTo describe the Versatile Teaching Eye (VT Eye), a 3D-printed model eye designed to provide an affordable examination simulator, and to report the results of a pilot program introducing the VT Eye and an ophthalmic training curriculum at a teaching hospital in Ghana.MethodsTinkerCAD was used to design the VT Eye, which was printed with ABS plastic. The design features an adapter that permits use of a smartphone as a digital fundus. We developed a set of digital flashcards allowing for an interactive review of a range of retinal pathologies. An analog fundus was developed for practicing traditional slit lamp and indirect examinations as well as retinal laser practice. The model was used for a period of 2 weeks by ophthalmic trainees at Komfo Anokye Teaching Hospital, Kumasi, Ghana, to practice indirect ophthalmoscopy, slit lamp biomicroscopy, smartphone funduscopy, and retinal image drawing. Results were assessed at by means of a pre-/post-training survey of 6 residents.ResultsThe VT Eye accommodates diverse fundus examination techniques. Its 3D-printed design ensures cost-effective, high-quality replication. When paired with a 20 D practice examination lens, the digital fundus provides a comprehensive, interactive training environment for <$30.00 (USD). This device allows for indirect examination practice without requiring an indirect headset, which may increase the amount of available practice for trainees early in their careers. In the Ghana pilot program, the model’s use in indirect examination training sessions significantly boosted residents’ confidence in various examination techniques. Comparing pre- and post-session ratings, average reported confidence levels rose by 30% for acquiring clear views of the posterior pole, 42% for visualizing the periphery, and 141% for capturing important pathology using personal smartphones combined with a 20 D lens (all P < 0.05).ConclusionsThe VT Eye is readily reproducible and can be easily integrated into ophthalmic training curricula, even in regions with limited resources. It offers an effective and affordable training solution, underscoring its potential for global adoption and the benefits of incorporating innovative technologies in medical education.

PurposeTo evaluate the prevalence of musculoskeletal (MSK) complaints in ophthalmologists and to assess whether participation in an online Iyengar yoga video program improves the baseline pain scores and awareness of proper posture in the clinic and operating room.MethodsOphthalmologists were recruited from online professional forums for this nonrandomized, prospective study. A pre-intervention survey, including demographics, office and procedure volumes, wellness activities, and baseline MSK pain scores, was completed. A fifteen-minute instructional video focusing on simple yoga poses for the neck, shoulder, and lower back created by one of the authors, who is both an ophthalmologist and a certified Iyengar yoga teacher, was provided to participants to complete three times weekly for a total of 4 weeks. A post-intervention survey collecting MSK pain scores and information about ergonomics and compliance was completed.ResultsFifty ophthalmologists completed the pre-intervention survey, of whom 49 (98%) reported at least 1 episode of MSK discomfort in the preceding year. Of those, discomfort was cervical in 36 (72%), in the shoulder(s) in 15 (29%), thoracic spinal in 23 (46%), lumbar spinal in 23 (46%), and centered in the wrist, hand, or finger in 22 (44%). Of the 50 ophthalmologists, 22 submitted the post-intervention surveys. The post-intervention pain scores were decreased compared to baseline for cervical spine (P < 0.01), shoulder (P < 0.01), thoracic spine (P < 0.01), lumbar spine (P < 0.01) and wrist, hand, or finger (P < 0.01). 20 respondents (91%) reported improved awareness of their posture in the clinic and operating room, and 19 (86%) felt that this awareness would decrease their MSK symptoms.ConclusionsAmong our small group of survey respondents, a fifteen-minute Iyengar yoga video program specifically designed for ophthalmologists reduced MSK pain and improving awareness of proper ergonomics for practicing ophthalmologists.

BackgroundLaboratory confirmation is crucial for diagnosis and management of herpes simplex virus (HSV) keratitis. However, the sensitivity of polymerase chain reaction (PCR) in keratitis is low (25%) compared with that of mucocutaneous disease (75%). We developed an educational intervention aimed at improving the diagnostic yield of PCR. MethodsThe medical records of keratitis cases seen at the emergency department of a London tertiary ophthalmic referral hospital over two distinct periods, before and after an educational program on swab technique, were reviewed retrospectively. ResultsA total of 252 HSV cases were included. Increases in the laboratory-confirmed diagnosis of HSV-1 were observed, in both first presentations (11.1%-57.7%) and recurrent cases (20%-57.6%). The rate of positive HSV-1 PCR in eyes with an epithelial defect increased from 19% pre-intervention to 62% post intervention. Notably, 3% were positive for varicella zoster virus DNA, and there was a single case of Acanthamoeba keratitis. ConclusionOur results suggest that, with proper swabbing technique, PCR may be more sensitive than previously reported.
