Assessment of internal limiting membrane flap and autologous whole blood techniques in complicated macular hole surgery.
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
purposeTo evaluate and compare the outcomes of internal limiting membrane (ILM) flap and autologous whole blood application for treatment of complicated macular holes (CMHs).
methodsA retrospective analysis of medical records was performed for patients who underwent vitrectomy for CMHs, including preoperative and postoperative evaluations at 1, 3, and 6 months. Patients were divided into two groups: Group 1 autologous whole blood and Group 2 ILM flap application. The hole parameters were measured using preoperative OCT images. The integrity of the external limiting membrane (ELM)-ellipsoid zone (EZ) and anatomical closure patterns was evaluated on postoperative OCT images. Closure patterns were scored.
resultsThe study included 37 eyes: 17 (45.9%) in Group 1 and 20 (54.1%) in Group 2. The postoperative closure rate was 94.1% in Group 1 and 100% in Group 2, with an overall rate of 97.3%. No significant differences were found between Groups 1 and 2 in OCT parameters, best-corrected visual acuity, ELM-EZ recovery, or macular edema reduction at any follow-up time point (p > 0.05). The optimal closure score was higher in group 2 at the first month postoperatively (p = 0.036), but no difference was detected at the third and sixth months (p = 0.870 and p = 0.780, respectively).
conclusionsThis study demonstrated that both autologous whole blood and ILM flap techniques are effective in the surgical management of CMHs, achieving high closure rates. Given its comparable postoperative results to the ILM flap, autologous whole blood may be a beneficial option in CMH surgery.
