Clinical value of phenylephrine testing in the upper and lower eyelids of patients with aponeurotic and congenital eyelid ptosis.

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 characterize the phenylephrine test in aponeurotic and congenital eyelid ptosis, to determine the appropriate timing of the phenylephrine test, and to assess the responses of the upper and lower eyelids.
methodsThis was a retrospective analysis of 140 eyes of 87 patients (mean age 52.29±16.45y; 22 males, 65 females) with upper eyelid ptosis. Totally 88.6% had aponeurotic and 11.4% had congenital ptosis. For the evaluation of the responses of the upper and lower eyelids to topical 2.5% phenylephrine, the scleral show height, the marginal reflex distance (MRD) between the inferior margin of the upper eyelid and pupillary light reflex (MRD1), and between the central portion of the lower eyelid and pupillary light reflex (MRD2) were measured at the 2
resultsThe mean MRD1, MRD2, and scleral show heights increased within 5min after testing, remaining largely stable between the 5
conclusionPerforming the phenylephrine test 5min after instilling the reagent is adequate to assess the maximum response of the upper and lower eyelids. The upper and lower eyelid responses in phenylephrine testing are poorly correlated. However, the ΔMRD2 is related with baseline scleral show degree that may be a postoperative predictive factor. Further studies are necessary to determine the relationship between the responses of the lower eyelids to phenylephrine testing.
