Dry eye parameters measured with an ocular surface analyzer in eyes after vitrectomy for vitreomacular interface disorders.

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
Purpose: Dry eye disease (DED) might be caused by multiple ocular surgical interventions. The aim of the study was to estimate the extent of DED in patients undergoing core vitrectomy for vitreoretinal interface disorders. Methods: In this prospective observational study, we included patients with 12 months of follow-up after vitrectomy. The following data were collected as controls: age, sex, best-corrected visual acuity before and after surgery, and phakic status. In OSA (ocular surface analysis), the following parameters were evaluated: NIBUT (non-invasive tear break-up time), sltDear (thickness of the lipid layer), Meibomian gland (MGD) loss, and the height of tear meniscus. Shapiro-Wilk test, Wilcoxon rank-sum test, and Mann-Whitney U tests were used for statistical analysis. Results: We evaluated 48 eyes of 24 patients (10 men, 14 women; 64.63 ± 14.10 years) 1 year after vitrectomy. From the analyzed ocular surface parameters, NIBUT was significantly lower in operated versus non-operated eyes (P = 0.048). The higher the level of difference in MGD loss between both eyes, the higher the level of difference in NIBUT between both eyes (r Conclusion: NIBUT levels were still decreased 12 months after vitrectomy. Patients with more pronounced MGD loss or decreased NIBUT levels in the fellow eye were more likely to experience such disorders. The tear meniscus height was lower in patients undergoing surgery for retinal detachment than in those with vitreoretinal disorders. This might allow the suggestion to include artificial tears in pre- and post-operative care in vitrectomized eyes.
