The influence of mild cataract on ISCEV standard electroretinogram recorded from mydriatic eyes.

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 investigate the effect of mild cataract and its surgery on the ISCEV standard electroretinogram (ERG) by comparing pre- and postoperative ERGs elicited from fully dilated eyes.
methodsTwenty-two patients participated. Each eye had cataract of grade 2 according to Emery-Little classification. None had complications during and after phacoemulsification and intraocular lens implantation. According to the ISCEV standard, pre- and 1-week postoperative full-field ERGs, dark adapted (DA) 0.01, DA 3, DA 3 oscillatory potentials (OPs), DA 10, and light adapted (LA) 3, and LA 3 flicker, were elicited from fully dilated eyes using skin electrodes. Photopic negative response (PhNR) 1 amplitude was measured from the baseline to the trough before the i-wave in the LA 3 ERG waveform. Statistical analysis was performed using SigmaPlot version 11.0 (Systat Software, Inc., San Jose, CA, USA). Pre- and postoperative data were compared using a paired t-test. Non-normally distributed data were evaluated using the Wilcoxon signed rank test.
resultsThe pre- and 1-week postoperative amplitudes in each component were as follows: DA 0.01: 48.4 ± 19.5 μV and 57.1 ± 20.0 μV (p = 0.002), a-wave of DA3: 51.5 ± 14.8 μV and 58.3 ± 17.3 μV (p = 0.003), b-wave of DA3: 88.3 ± 27.5 μV and 101.5 ± 29.7 μV (p = 0.003), DA 3 ΣOPs (sum of DA 3 OP1, OP2, and OP3 amplitude): 30.7 ± 16.3 μV and 37.1 ± 21.9 μV (p < 0.001), a-wave of DA 10: 65.5 ± 18.8 μV and 74.2 ± 19.5 μV (p < 0.001), b-wave of DA 10: 95.5 ± 29.6 μV and 111.1 ± 29.9 μV (p < 0.001), a-wave of LA 3: 7.2 ± 2.6 μV and 8.2 ± 2.2 μV (p = 0.025), b-wave of LA 3: 30.6 ± 12.9 μV and 35.3 ± 12.7 μV (p = 0.003), PhNR1: 5.8 ± 2.5 μV and 5.5 ± 2.6 μV (p = 0.562), and LA 3 flicker: 25.4 ± 8.9 μV and 27.8 ± 8.6 μV (p = 0.039), respectively. The implicit time of all the components did not reveal significant differences before and after surgery.
conclusionsCataractous lens removal and intraocular lens implantation may influence ISCEV standard ERGs, even if the cataract is relatively mild.
