1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aimed to evaluate the feasibility of ultra-widefield swept-source optical coherence tomography angiography (UWF SS-OCTA) in guiding laser photocoagulation for retinal vascular diseases.

methodsA total of 285 eyes from 195 patients with retinal vein occlusion and diabetic retinopathy were retrospectively evaluated at the Medical Retina Department of Zhongshan Ophthalmic Center, Sun Yat-sen University, from July 24 to October 27, 2023. All patients underwent UWF SS-OCTA (VG200, Intalight Imaging, Ltd, Luoyang, China) examination with a single scan using the widefield AngioMosaic protocol. A subset of patients also underwent fluorescein fundus angiography and fundus photography based on clinical discretion. Retinal nonperfusion area, a key biomarker for guiding laser photocoagulation, along with other findings such as existing laser spots were analyzed to guide treatment.

resultsThe UWF SS-OCTA produced a 29 × 24-mm single-scan angiographic image and generated a 220° field-of-view montage. Images of the retinal superficial vascular complex could distinctly depict nonperfusion area, retinal neovascularization, and intraretinal microvascular abnormalities, while enhanced angio mode images of the choroidal capillary layer effectively demonstrated the location of existing laser spots. Using the UWF SS-OCTA findings, initial photocoagulation therapy was performed in 34.3% of patients with retinal vein occlusion and 15.8% of patients with diabetic retinopathy, and supplementary photocoagulation was applied in 13.9% of patients with retinal vein occlusion and 13.6% of patients with diabetic retinopathy.

conclusionUWF SS-OCTA images of the retinal superficial vascular complex and the choroidal capillary layer with the enhanced angio mode provide a noninvasive, efficient, and precise method for guiding retinal photocoagulation, representing a viable alternative to conventional invasive techniques.
