Iris varix: 10-year experience with 28 eyes.
Observational study in Indian journal of ophthalmology, 2019. 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
purposeThe purpose of this study is to describe the clinical characteristics, multimodality imaging findings, and clinical course of iris varices.
methodsRetrospective, noncomparative, observational case series of 28 eyes of 26 patients with iris varices, diagnosed between 2007 and 2017, has been used.
resultsThe mean (±SD) age was 58.3 ± 12.5 years (median 57.5, range 37-81). Patients were 57.7% male and 27% hypertensive. Varices were bilateral in two patients. The mean and median visual acuities were both 20/20 (range 20/16-20/40). Intraocular pressures were 16 mmHg (10-23 mmHg). Secondary glaucoma did not occur. The inferotemporal iris quadrant was affected in 75%. A single varix was seen in 64% and 36% appeared multiple. Varix orientation was radial in 57% and circumferential in 21%. Combined radial and circumferential varix orientation was noted in 18%. One had independent radial and circumferential varices in separate quadrants. A single episcleral sentinel blood vessel directed to the varix was present in 36%. Ultrasound biomicroscopy (UBM) showed a slightly increased mean iris thickness of 0.8 mm and multiple echolucent iris stromal vascular channels. Iris angiography showed no leakage of dye. Managed by observation over a mean follow-up of 37.7 months (range, 3-129), 96.4% eyes were stable and one (3.6%) regressed. No corectopia, ectropion uveae, hyphema, or metachronous anterior segment benign or malignant tumors occurred.
conclusionIris varix is primarily located in the inferotemporal quadrant and not associated with dysmorphic pupillary findings, progression, secondary glaucoma, or malignancy. Iris varices were benign vasculopathies with no associated ocular or vision-related morbidity.
