W e read with great interest the study by Shanmugam et al. examining the feasibility of systematic nonmydriatic ocular fundus photography combined with optical coherence tomography in a general emergency department setting. The authors provide valuable prospective data on workflow integration, image quality, and real-world barriers to implementation. Their findings offer an important contribution to the ongoing discussion regarding the role of ocular imaging as an adjunct to emergency neurologic and ophthalmologic evaluation.
The reported 51% imaging completion rate, despite 24/7 dedicated study personnel, frames the practical constraints of large-volume emergency departments. Although the authors characterize this as a best-case scenario, the inclusion of broad screening indications such as history of diabetes mellitus and end-stage renal disease likely inflated the denominator of eligible patients beyond what most emergency clinicians would prioritize during acute triage. A stratified feasibility analysis restricted to time-sensitive indications, including acute vision loss, headache with suspected papilledema, hypertensive crisis, and focal neurologic deficits, would clarify the achievable completion rate for clinically urgent presentations and better inform implementation strategies.
The association between older age and lower imaging completion also warrants closer clinical interpretation. The decline in imaging likelihood per additional year of age suggests that patients at potentially higher risk for sight-threatening or cerebrovascular disease were less frequently imaged due to instability or competing medical priorities. This introduces a selection effect that may limit the applicability of systematic screening models. Future protocols could incorporate portable or bedside imaging solutions for medically unstable patients to mitigate this disparity.
Image quality metrics were robust, with more than 90% of studies providing adequate diagnostic information from either color photography or optical coherence tomography. The complementary value of structural optical coherence tomography in cases where fundus photography alone was insufficient reinforces the advantage of hybrid systems. However, the clinical impact of these imaging findings on downstream management remains incompletely quantified. Reporting time-to-diagnosis, reduction in unnecessary neuroimaging, or changes in consultation patterns would strengthen the argument for routine integration.
Workflow analysis identified process-related barriers, including early admission, discharge prior to imaging, and camera-room access. These operational bottlenecks suggest that integration into triage pathways rather than post-evaluation workflows may improve completion rates. Embedding imaging orders within standardized headache or vision-loss order sets may also enhance consistency without overextending emergency department resources.
The authors appropriately caution against indiscriminate expansion of screening in busy tertiary centers. While the concept of “oculomics” holds promise, emergency departments primarily serve to identify and stabilize acute pathology. Systematic screening for chronic conditions must be balanced against throughput pressures and acuity demands. Implementation decisions should therefore remain context-specific and aligned with institutional capacity.
Overall, this study provides thoughtful, data-driven insight into the realities of adopting advanced ocular imaging technology in acute care settings. By delineating both diagnostic yield and operational constraints, it advances a nuanced framework for integrating nonmydriatic fundus imaging into emergency practice while maintaining realistic expectations regarding feasibility and scope.
