Visual and anatomical outcomes of primary retinectomy for diabetic tractional retinal detachment.
Article in BMC ophthalmology, 2025. 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
purposeUncontrolled proliferative diabetic retinopathy (PDR) can cause fibrovascular growth and retinal traction, leading to tractional retinal detachment (TRD). The role of primary retinectomy in diabetic TRD remains unclear, as most studies focus on rhegmatogenous retinal detachment (RRD) with PVR. This study aims to investigate the impact of retinectomy on anatomical and visual outcomes in patients undergoing pars plana vitrectomy (PPV) for diabetic TRD.
methodPatients who underwent primary retinectomy during PPV for diabetic TRD were retrospectively evaluated. Best corrected visual acuity (BCVA) before surgery and at the final follow-up, retinectomy characteristics, and final retinal attachment status were documented. TRD score, the quadrant and extent of the retinectomy, presence of macular displacement at final follow-up, and postoperative complications were evaluated. The relationship between the quadrants and extent of the retinectomy and visual acuity was also assessed.
resultThirty-eight eyes of 38 patients with mean age 60.55 ± 10.00 years were included. Mean follow-up was 23.53 ± 27.40 months. The most common locations of the retinectomy sites were extended posterior to the equator (39.5%), around the equatorial zone (34.2%), and peripheral retina (26.3%). The mean BCVA improved from 1.71 ± 0.53 logMAR to 1.48 ± 0.74 logMAR at the final follow-up. At the final visit 65.8% of patients experienced improved or maintained BCVA. Temporal retinectomy showed worse visual outcomes in the Chi-square test but not in binary logistic regression analysis. Furthermore, 26 (68.4%) eyes were attached without tamponade, 10 (26.3%) were attached under silicone oil and 2 (5.6%) remained detached under silicone oil.
conclusionThese findings suggest that retinectomy, when deemed necessary in eyes with diabetic TRD, may not lead to poor functional and anatomical outcomes, contrary to some previous assumptions.
