Ocular fundus and optical coherence tomography (OCT) findings in children prenatally exposed to opioid maintenance therapy (OMT).
Article in BMC 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
backgroundOptical coherence tomography (OCT) has been of great importance in the diagnostics and follow-up of many retinal diseases the last 25 years. More recently, this technology has also proved useful in the evaluation and follow-up of various neurological and psychiatric disorders. Also, certain prenatal impacts, such as prematurity and foetal alcohol spectrum disorder have shown abnormal findings on OCT. The aim of this study was to examine children that have been prenatally exposed to opioid maintenance therapy (OMT) with OCT.
methodsAs a part of a comprehensive study on visual and visual-motor function, 63 children aged 5-13 years exposed prenatally to OMT and 77 age-matched controls were examined with OCT, collecting data from the peripapillary retinal nerve fibre layer (RNLF) and the macular region. The participants were recruited at two different centres with different OCT-instruments.
resultsA highly significant thinning of the peripapillary RNFL was found in the OMT-exposed children compared to the controls at both study centres. The macular data did also show a reduced retinal thickness and volumes in several macular regions in the OMT-exposed children, but to a variable degree at the two participating study centres. The reasons for this variability remain uncertain. There was no correlation between the OCT data and visual acuity.
conclusionsThis is the first study reporting OCT-data from children prenatally exposed to OMT. The significant thinning of the peripapillary RNFL in the OMT-exposed children most probably reflects a negative impact of the opioid substances on the foetal neurodevelopment. Further OCT-studies on OMT-exposed children should be carried out.
