Spontaneous Recovery of Traumatic Unilateral Superior Oblique Palsy and Ocular Factors for Predicting Prognosis.
Article in Korean journal of ophthalmology : KJO, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 evaluated the prognosis of patients with traumatic unilateral superior oblique palsy (SOP) and clinical factors associated with spontaneous resolution.
methodsMedical records of patients with traumatic unilateral SOP who visited two hospitals (Yeungnam University Hospital and Daegu Catholic University Medical Center) between January 2015 and June 2020 were reviewed retrospectively. When traumatic unilateral SOP did not recover within at least 1 year of follow-up, no spontaneous resolution was considered. Both traumatic and ocular factors were evaluated to evaluate their association with spontaneous recovery.
resultsFifty-nine patients (mean age, 52.6 years; 48 male patients) were enrolled in this study. The mean interval from trauma to initial presentation was 3.9 months. The mean vertical deviation at initial presentation was 6.34 ± 5.22 prism diopters (PD) (range, 0-25 PD). During the mean 24.1-month follow-up period, 28 patients (47.5%) achieved spontaneous resolution of SOP. Thirteen patients underwent surgical treatment for SOP. Vertical deviation <6 PD at the initial visit and low fundus torsion in the nonparetic eye and both eyes were significantly associated with spontaneous recovery (p < 0.05, logistic regression analysis). Traumatic factors, including the trauma type, presence of intracranial lesion, loss of consciousness, and Glasgow Coma Scale score, were not associated with spontaneous recovery.
conclusionsIn this multicenter study, spontaneously recovery was achieved in 47.5% patients with traumatic unilateral SOP. Even mild head trauma can lead to permanent SOP. Ocular factors, including the angle of deviation and fundus torsion, may better predict spontaneous resolution than traumatic factors in patients with traumatic unilateral SOP.
