Transvitreal endoresection of peripheral exudative hemorrhagic chorioretinopathy: a clinicopathological study.
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
backgroundTo report a rare case of presumed early-stage peripheral exudative hemorrhagic chorioretinopathy (PEHCR), which was removed by transvitreal approach, and analyze the histological findings. CASE PRESENTATION: A 76-year-old Japanese woman presented with a fundus lesion in her left eye, and was referred to our university hospital. Her best-corrected visual acuity was 1.0 with normal intraocular pressure in both eyes. The color fundus revealed a whitish elevated lesion, measuring about 2 disc diameters, in the inferior fundus. Fluorescein angiography depicted hyperfluorescence and fluorescein leakages in the lesion in the early and late phases, respectively. Indocyanine green angiography demonstrated the hypofluorescence in the lesion without any hyperfluorescent spots. Swept-source optical coherence tomography of the lesion demonstrated a subretinal solid mass with subretinal fluid and pigment epithelial detachments. Since clinical diagnosis of the fundus lesion could not be made, transvitreal endoresection of the lesion was conducted by pars plana vitrectomy. Her visual acuity remained good with no any complications 1 year after vitrectomy. Histopathologically, the lesion was made up of AE1/AE3 (an epithelial marker)-positive retinal pigment epithelial cells, with CD34 and alpha-smooth muscle actin-positive vessel walls, which were consistent with choroidal neovascularization (CNV). These clinicopathological findings led to the diagnosis of PEHCR.
conclusionThis is the first reported case of transvitreal endoresection of PEHCR, and the histopathology indicated that the origin was peripheral CNV.
