This study aimed to compare the clinical performance between a smartphone-based fundus photography device and a contact imaging device for retinopathy of prematurity (ROP) screening. All patients were first examined with binocular indirect ophthalmoscopy (BIO), which served as the reference standard. The patients were then assessed by two devices. Imaging quality, ability to judge the zone and stage of ROP, agreement with the BIO results, vital signs, and pain scores were compared between these two devices. In total, 142 eyes of 71 infants were included. For the smartphone-based fundus photography, image quality was graded excellent or acceptable in 91.4% of examinations, although it was still significantly inferior to that of the contact imaging device (p < 0.001). The smartphone-based fundus photography images had moderate agreement with the BIO results regarding the presence or absence of plus disease (Cohen’s κ = 0.619), but evaluating the zone (p < 0.001) and stage (p < 0.001) of ROP was difficult. Systemic parameters, except for heart rate, were similar between the two imaging devices (all p > 0.05). In conclusion, although the smartphone-based fundus photography showed moderate agreement for determining the presence or absence of plus disease, it failed to identify the zone and stage of ROP.

Introduction: This study aimed to compare ocular torsion measurements to investigate normative objective cyclotorsion values in a population of healthy, full‐term and preterm children.Materials and Methods: The participants enrolled in this study had an age range of 3–12 years and were divided into two groups, full‐term (gestational age (GA) > 37 weeks) and preterm without retinopathy of prematurity (ROP) (GA ≤ 37 weeks). The disc‐center‐fovea angle (DFA) was used to evaluate ocular torsion using two different imaging modalities: optical coherence tomography (OCT) with a 55‐degree field of view (FV) and conventional fundus photography (CFP) with a 45‐degree FV. The values measured from both right and left eyes were combined to obtain a single value to compensate for the effect of head tilt during measurement.Results: A total of 86 full‐term and 145 preterm children were enrolled in this study. The DFAs measured using OCT and CFP were −11.57° ± 5.27° and −12.07° ± 5.66° in the full‐term group and −10.64° ± 5.40° and −11.25° ± 4.80° in the preterm group, respectively. There were no significant differences between the results obtained from OCT and CFP in the two groups (p = 0.109 and p = 0.512, respectively). There was a strong correlation between OCT and CFP in all patients, with a Pearson’s correlation coefficient of 0.74 and an intraclass correlation coefficient (ICC) of 0.74 (both p < 0.001). Multivariate regression analysis showed that the average axial length (AXL) was associated with DFA.Conclusions: This study found a significant correlation between DFA measured using OCT and CFP, making either measurement modality feasible in pediatric populations. There was no significant difference in the DFA between full‐term and preterm children. AXL demonstrated an association with the DFA.

Although Taiwan was one of the first countries to develop coronavirus disease 2019 (COVID-19), with effective antiepidemic measures, Taiwan has effectively controlled the spread of the disease. The purpose of this article is to provide useful safety strategies for ophthalmologists in daily practice during the COVID-19 pandemic. Infection control strategies in the hospital and Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou, are discussed. Ophthalmologists are at high risk of contracting COVID-19 infection, as they have close contact with patients during ocular examinations, and are also facing high patient volume in outpatient clinics as well as emergency consultations. Furthermore, ocular symptoms, such as conjunctivitis, may be the presenting signs of COVID-19 infection. We provide our strategies, which include hospital's gate control with triage station, patient volume control, proper personal protective equipment, and consultation with telemedicine technology, to decrease the risk of cross-infection between medical staffs and patients. To achieve the goal of preventing viral spread and maximizing patient and medical staffs' safety, besides providing proper protective equipment, it is also crucial for staffs and patients to strictly follow antiepidemic measures. We hope that our experience can help ophthalmologists and health-care workers to have a safer working environment when facing COVID-19 pandemic.

This prospective study aimed at determine whether eye irrigation removes ocular foreign bodies (FBs) and whether ocular pain predicts FBs. Emergency department patients complaining of ocular FBs were enrolled. In the irrigation group (n = 52), pain was evaluated with a visual analog scale before and after irrigation, and the presence of FBs was determined under a slit-lamp. In the nonirrigation group (n = 27), the evaluations were performed upon arrival. The corneal FB retention rate was found significantly lower in the irrigation (13/52, 25%) than in the nonirrigation groups (13/27, 48%; P = 0.04). After irrigation, those without FBs had more patients experiencing pain reduction (67%) compared to those with retained FBs (46%; P = 0.14) and had a greater magnitude of change in pain score (mean ± SD, − 2.6 ± 2.7 vs. − 0.7 ± 1.4; P = 0.02). An improvement in ocular pain score ≥ 5 points after irrigation predicted the absence of FBs with a negative predictive value of 100%. Eye irrigation significantly lowered corneal FB retention; if ocular pain decreased considerably, the probability of retained FBs was low, making irrigation-associated pain score reduction a feasible diagnostic method to exclude FB retention without needing specialized ophthalmic examinations.
