12-year cumulative incidence rate of rare retinal diseases: a nationwide study in Korea.
Article in Eye (London, England), 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
purposeUnderstanding the incidence of rare diseases is important in establishing a proper public health care system and setting target diseases in medical research. Herein, we report the 12-year cumulative incidence of seven rare ocular diseases of the retina in South Korea.
methodsWe analysed clinical records of 1,126,250 South Korean population during 2006~2019. We conducted a nationwide, population-based, cohort study using data from the Korean National Health Claims database. With codes in the Korean Standard Classification of Diseases, the cumulative incidence of each retinal disease (Choroideremia, Eales disease, Coats disease, Retinitis pigmentosa, Best disease, Stargardt disease, and Leber's congenital amaurosis) was calculated. Incidences in different sex and age groups were also assessed.
resultsLate-onset diseases had a higher incidence rate in adulthood, but there were no definite differences between sex. The 12-year cumulative incidence per 100,000 people in rare retinal diseases was 0.66 to 28.45. Among them, retinitis pigmentosa revealed higher incidence (28.45 (95% CI 25.59-31.30) in total, 29.33 (95% CI 23.67-34.99) in males, 29.47 (95% CI 25.38-33.55) in female). Late-onset rare retinal diseases such as Eales diseases and Best diseases have higher incidence rates in adults. The incidence difference according to gender was not significant.
conclusionsThis study determined the estimated long-term cumulative incidence rate of rare retinal diseases and the distribution of the incidence based on sex and age. The nationwide epidemiological data would give useful information for public health and further research.
