Swept-Source OCT Angiography Features of Melanotic Choroidal Tumors: An Analysis of 102 Consecutive Cases.

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
Purpose: To quantitatively analyze swept-source OCT angiography (SS-OCTA) features of choroidal melanoma and nevi, focusing on their distinguishing angiographic features. Design: Case-series study. Participants: This retrospective study included 102 consecutive patients with choroidal melanoma or nevi who were referred to Beijing Tongren Hospital between July 2019 and June 2024. Main Outcome Measures: The choriocapillaris and choroid slabs were en face reconstructed. A 5-grade system was developed based on the density and morphology of disorganized vasculature in the choroid slab. Choriocapillaris flow deficit (CCFD%) void was calculated within circular regions defined by the tumor's radius and diameter. Methods: This retrospective study included 102 consecutive patients with choroidal melanoma or nevi referred to Beijing Tongren Hospital between July 2019 and June 2024. The choriocapillaris and choroid slabs were en face reconstructed. A 5-grade system was developed based on the density and morphology of disorganized vasculature in the choroid slab. Choriocapillaris flow deficit (CCFD%) void was calculated within circular regions defined by the tumor's radius and diameter. Results: Of all the 102 patients, 87 (85%) patients with qualified SS-OCTA images, comprising 61 cases of choroidal melanoma and 26 cases of nevi. Sixty melanoma cases (98%) exhibited disorganized tumor vasculature forming twisted vessel loops and networks on the choroid slab (grade ≥2). Nevi showed 2 types of intrinsic tumor vasculature patterns in the choroidal slab: well-organized (grade 0 or 1) and melanoma-like disorganized networks (grade ≥2). Classified based on multimodal imaging risk score, nevi with a high risk for growth (≥2 risk factors) were more likely to exhibit melanoma-like disorganized networks tumor vasculature (82% vs. 27%, Conclusions: Swept-source OCT angiography enables detailed noninvasive assessment of intrinsic vasculature in melanotic choroidal tumors.
