Correlation between Portable Photopic Electroretinography and Postoperative Best-Corrected Visual Acuity in Patients with Diabetic Vitreous Hemorrhage.
Article in Korean journal of ophthalmology : KJO, 2026. 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
purposeTo determine the correlation between electroretinography (ERG) performed using a handheld ERG device equipped with skin electrodes and postoperative best-corrected visual acuity (BCVA) in patients with vitreous hemorrhage (VH) due to proliferative diabetic retinopathy (PDR).
methodsThe medical records of patients who underwent vitrectomy for diabetic VH caused by PDR at our institution between July 1, 2017, and June 30, 2023, were reviewed retrospectively. We analyzed the correlation between preoperative ERG obtained using a handheld ERG device (RETeval), RETeval skin electrodes (Sensor Strips), and postoperative BCVA.
resultsWe evaluated the medical records of 70 eyes of 70 patients. The BCVA, which was measured in logMAR units, improved from 1.910 ± 0.504 preoperatively to 0.287 ± 0.225 postoperatively (p < 0.001). In the group that underwent panretinal photocoagulation before VH, the amplitudes of the b-wave in photopic ERG and 30-Hz flicker ERG were negatively correlated with the postoperative BCVA. The implicit times of the b-wave in photopic ERG and 30-Hz flicker ERG were positively correlated with the postoperative BCVA (p < 0.05).
conclusionsPhotopic ERG recorded using a handheld retinal ERG device equipped with skin electrodes can aid in predicting the visual prognosis in patients with severe VH caused by diabetes mellitus.
