CHARACTERISTICS AND VITREORETINAL MANAGEMENT OF RETINAL DETACHMENT IN EYES AFTER PENETRATING KERATOPLASTY IN a 10-YEAR STUDY.
Article in Retina (Philadelphia, Pa.), 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 investigate the incidence, clinical characteristics, and possible pathogenesis of retinal detachment (RD) after penetrating keratoplasty (PK), and to assess the impact of RD and vitreoretinal surgery on the postoperative effects and prognosis of PK surgery.
methodsA retrospective review of 3,241 eyes from 2,884 patients who underwent PK was conducted. RD incidence, characteristics, and outcomes of vitreoretinal surgery were analyzed.
resultsThe incidence of RD after PK was 1.32%, with a mean follow-up of 7.7 years. RD occurred on average 28.3 months post-PK, sooner in eyes with multiple PKs. A unique traction RD pattern was identified, with anterior proliferative vitreoretinopathy (PVR) observed in 73.9% of cases during pars plana vitrectomy (PPV). This caused RD without detectable retinal breaks due to anterior displacement of the retina and vitreous base. Endoscope-assisted PPV in eyes with opaque corneas resulted in better visual acuity and silicone oil removal rates than standard techniques. Clear graft eyes retained silicone oil more frequently than those with opaque grafts.
conclusionRD after PK is a rare complication, characterized by severe anterior PVR, presenting significant surgical challenges. Effective management involves specialized surgical interventions. Early detection and tailored surgical strategies are crucial for improving patient outcomes after PK.
