Abstrakt: Aim: The aim of this retrospective review was to analyse the frequency of patients presenting with flashes and/or floaters (F/F) on bright versus dark days to the eye emergency department of a tertiary referral hospital (the Mater Misericordiae University Hospital) over a 3-year period. The diagnostic and clinical outcomes of F/F presentations were also analysed. Methods: This retrospective study assessed eye casualty attendances between January 2018 and December 2020. Solar irradiation (j/cm2) at ground level was retrieved from the records of Met Eireann (Irish National Meteorological Service) via their open access records. A review of electronic patient medical records using the in-house database patient centre was carried out of all patients who attended EED of during the study timeline on the 5 'brightest' and 5 'darkest' days of each year. Results: Seven hundred forty patient presentations were analysed in total. Overall, 16% (n = 119) of all patients that attended EED during the timeframe of the study presented with F/F. One hundred six patients (89%) presented with floaters, 40 patients (34%) presented with flashing lights/photopsia, and 35 patients (29%) presented with both F/F. More patients presented to EED with F/F on bright days when compared with dark days (74 vs 45, p < 0.05). Eighty-nine percent of all patients with F/F presented with monocular floaters. There were more floater presentations during bright when compared with dark days (70 vs 36, p < 0.05). More patients were diagnosed with PVD on bright days when compared with those diagnosed with PVD on dark days (43vs 15, p < 0.05). More RDs were diagnosed on dark days compared with bright days (7 vs 3, p < 0.05). Conclusion: This study established that F/F presentations were more likely to present during bright days when compared with dark days. The diagnosis of PVD was more common during bright days, and RDs were diagnosed significantly more frequently on dark days. Although incident solar radiation was correlated with greater floaters/PVD presentation, causation is unlikely, and the duration of PVD may have been longer in patients presenting on bright days (i.e. pseudo-sudden symptoms).
