The clinical value of the multi-channel PVEP and PERG in the diagnosis and management of the patient with pituitary adenoma: a case report.

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
purposeTo present a patient with a diagnosis of pituitary adenoma and progressive visual pathway dysfunction detected in the electrophysiological tests in one-year follow-up. Patient is a 59-year-old male with a non-secreting pituitary macroadenoma.
methodsRoutine ophthalmological evaluation, standard automatic perimetry (SAP), retinal nerve fibers layer and the ganglion cell complex thickness in optical coherent tomography (OCT), as well as electrophysiological examinations (pattern electroretinogram-PERG, multi-channel pattern visual evoked potentials-multi-channel PVEPs record according to ISCEV standards) were performed. The examination and additional tests were conducted 3 times (in 0, 6 and 12 months) and 6 months after neurosurgery.
resultsVisual acuity, funduscopic examinations, SAP, OCT and electrophysiological test results at the first visit were all normal. In both eyes, the abnormalities were observed only in the multi-channel PVEP and PERG despite the absence of the changes in the routine ophthalmological examination and additional tests after 6- and 12-month follow-up. The tumor growth but without chiasmal compression was confirmed by magnetic resonance imaging. The progression of the optic pathway dysfunction in the electrophysiological tests was a cause of surgical removal of the pituitary tumor.
conclusionThis case highlights novel observations that in patients with pituitary tumor, detection of the early dysfunction of the visual pathway may lead to modification of the medical treatment regimen and reduce the incidence of irreversible optic nerve damage.
