Efficacy of pars plana vitrectomy for symptomatic vitreous floaters associated with Fuchs heterochromic iridocyclitis.
Article in BMC ophthalmology, 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
backgroundSymptomatic vitreous floaters can significantly impair visual function and quality of life. While pars plana vitrectomy (PPV) has been shown to be effective for vitreous opacifications, data regarding its outcomes in patients with Fuchs heterochromic uveitis (FHU) remain limited.
methodsThis retrospective study included 17 eyes of 17 pseudophakic patients with Fuchs heterochromic uveitis who underwent pars plana vitrectomy for visually significant vitreous opacification and were followed for a minimum of 3 months postoperatively. Preoperative and postoperative best-corrected visual acuity (BCVA), vitreous haze graded according to the Standardization of Uveitis Nomenclature (SUN) classification, intraocular pressure (IOP), and macular optical coherence tomography (OCT) findings were evaluated. BCVA values were converted to logarithm of the minimum angle of resolution (logMAR) for statistical analysis. Changes in visual and anatomical outcomes were analyzed, and the association between preoperative vitreous haze grade and postoperative visual improvement was assessed.
resultsThe mean duration of symptomatic vitreous floaters was 15.5 ± 6.2 months. Mean BCVA improved significantly from 0.57 ± 0.33 logMAR preoperatively to 0.18 ± 0.21 logMAR at the final follow-up (p < 0.001). The mean vitreous haze grade decreased significantly from 1.88 ± 0.78 to 0.12 ± 0.49 postoperatively (p < 0.001). A moderate positive correlation was observed between preoperative vitreous haze grade and postoperative visual improvement (Spearman’s ρ = 0.49, p = 0.044). Mean IOP did not differ significantly between preoperative and postoperative periods. One patient (5.8%) developed postoperative retinal detachment. No cases of cystoid macular edema or secondary epiretinal membrane formation were observed during follow-up.
conclusionsPars plana vitrectomy is an effective treatment option for symptomatic vitreous floaters associated with Fuchs heterochromic uveitis, providing significant visual improvement with an acceptable short-term safety profile. Careful patient selection and meticulous surgical technique are essential to optimize outcomes.
