Inverted internal limiting membrane flap technique for full-thickness macular holes in Black Africans.
Article in International 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
purposeTo report the outcomes of inverted internal limiting membrane (ILM) flap 'flower-petal' surgical technique for the treatment of full-thickness macular hole (FTMH) in patients from Rwanda.
methodsThis is a retrospective consecutive case series of all cases of FTMH that underwent pars plana vitrectomy (PPV) surgery with inverted ILM flap technique between April 2022 and March 2023 at the Kabgayi Eye Unit. The primary outcome was the anatomical success defined as FTMH closure. The secondary outcome was the change in best-corrected visual acuity (BCVA) before surgery and at final visit, termed as ΔBCVA.
resultsA total of ninety-eight eyes of ninety-eight patients (65% females) were included in the analysis. Mean patient age was 61.3 ± 15.7 years (range 7-82). Mean follow-up duration was 8.9 ± 4.2 months (range 2-15). Mean minimum linear diameter (MLD) was 549 ± 315 µm (range 50-2150). Postoperative macular hole closure rate was 93%. Mean BCVA improved from 1.24 ± 0.37 logMAR (range 0.4-2) to 0.95 ± 0.50 logMAR (range 0-3; p-value < 0.001). Most patients (56%) underwent PPV only, while in the remainder PPV was combined with phacoemulsification cataract surgery. SF6 gas was the most commonly used postoperative tamponade (37%), followed by C3F8 (36%) and C2F6 (27%). Postoperative complications were encountered in 6 cases (6%), the most common being eccentric macular holes (5%).
conclusionThe inverted ILM flap technique for FTMH in a Black African population demonstrated a high anatomical success rate. Our results will guide future management practices for the Black African ethnicity where FTMH outcomes are notoriously worse.
