COVID-19 impact on retinal detachment in Germany: seasonal peaks persist and shifts in surgical trends.
Observational study in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study investigated how the COVID-19 pandemic coincided with changes in incidence, seasonality, and surgical management of rhegmatogenous retinal detachment (RRD) and tractional retinal detachment (TRD) in Germany.
methodsWe performed an observational, retrospective analysis using data from the Diagnosis-Related Group database, covering 116,386 retinal detachment admissions between January 2019 and December 2022. RRD (ICD-10 H33.0) and TRD (ICD-10 H33.4) cases were examined separately. Seasonal decomposition and correlation analyses were applied to identify trends in admission numbers, surgical choices, and reoperations before and after the onset of COVID-19.
resultsA total of 96,620 RRD and 19,766 TRD admissions were analyzed. Post-pandemic, RRD decreased by 8.5%, whereas TRD declined by 2.9%. Despite disruptions, established seasonal peaks remained evident, with RRD peaking in July and TRD in March and August. A negative correlation between COVID-19 deaths and RRD cases suggested a temporal association that may reflect barriers to timely care during pandemic peaks. Surgical practice shifted toward more definitive vitrectomy approaches, and reoperation rates for RRD rose slightly from 12.1 to 12.9%.
conclusionThe pandemic correlated with reduced RRD admissions, smaller declines in TRD, and persistent seasonality in Germany. These findings underscore the importance of adaptive healthcare strategies that preserve timely surgical interventions and resource allocation for sight-threatening conditions during public health crises.
