AI Article Synopsis
- The optokinetic reflex (OKR) is crucial for assessing visual system development in infants and can be effectively studied using zebrafish larvae due to their rapid growth and suitability as a model organism.
- This research introduces a new, portable OKR assay that utilizes the Samsung Galaxy Z Flip, contrasting it with a traditional LCD setup for zebrafish testing.
- The study found that both assays successfully measured eye movements with similar accuracy and no significant differences in results, highlighting the advantages of the new approach in terms of convenience and cost-effectiveness.
Article Abstract
The optokinetic reflex (OKR) serves as a vital index for visual system development in early life, commonly observed within the first six months post-birth in humans. Zebrafish larvae offer a robust and convenient model for OKR studies due to their rapid development and manageable size. Existing OKR assays often involve cumbersome setups and offer limited portability. In this study, we present an innovative OKR assay that leverages the flexible screen of the Samsung Galaxy Z Flip to optimize setup and portability. We conducted paired slow-phase velocity measurements in 5-day post-fertilization (dpf) zebrafish larvae (n = 15), using both the novel flip-phone-based assay and a traditional liquid-crystal display (LCD) arena. Utilizing Bland-Altman plots, we assessed the agreement between the two methods. Both assays were efficacious in eliciting OKR, with eye movement analysis indicating high tracking precision in the flip-phone-based assay. No statistically significant difference was observed in slow-phase velocities between the two assays (p = 0.40). Our findings underscore the feasibility and non-inferiority of the flip-phone-based approach, offering streamlined assembly, enhanced portability, and the potential for cost-effective alternatives. This study contributes to the evolution of OKR assay methodologies, aligning them with emerging research paradigms.
