Ultrasonographic visualization of lower eyelid structures and dynamic motion analysis.
Article in International journal of ophthalmology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimTo define the ultrasonographic structure of normal lower eyelid anatomic compartments and their spacial relationship in dynamic motion.
methodsHigh resolution ultrasound (15MHz) was performed on the lower eyelids of 7 normal subjects. Movements of the lower eyelid and its compartments were visualized with ultrasound. In addition, the maximal excursion area of the lower eyelid fat compartments and retractor motions was measured before and after motion.
resultsThe orbicularis muscle could be seen as an echolucent structure between the dermis and the echodence fat pads. Lower eyelid fat pad seems to be divided into 2 compartments as range of motion and direction of movement of each of them varies. It seems that these compartments have also different behavior. The measured profile area of the visible normal lower eyelid fat pads during movement of globe from up-gaze to down-gaze decreased by 50%. Order of movement of lower eyelid structures seems to be as follows: after globe movement fist we see retractor movement, anterior orbital fat pad, then skin and septum, and finally movement of inferior fat pad.
conclusionUltrasound represents a noninvasive tool for the visualization of lower eyelid morphology. Expanding its application could help us understand the compartmental changes in physiological eyelid movement, in aging and diseased study populations, as well as assess operative outcomes.
