Perifoveal exudative vascular anomalous complex (PEVAC) resembling lesion in a patient with multiple myeloma.

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 report a case of a perifoveal exudative vascular anomalous complex (PEVAC) resembling lesion in a patient with multiple myeloma. Observations: A 56-year-old male with multiple myeloma presented with sudden moderate vision loss in the right eye. Best-corrected visual acuity was 20/25 in his right eye. Fundus examination showed a vascular irregularity in the perifoveal region. Fluorescein angiography (FA) revealed an isolated perifoveal aneurysmal lesion with minimal leakage. On optical coherence tomography (OCT) examination, a large oval structure with a hyperreflective wall and exudation was visualised. Three weeks later, spontaneous improvement of the intraretinal fluid was observed on OCT without treatment. However, 3 months later the macular edema recurred. The appearance of the aneurysmal lesion is similar to a PEVAC lesion, which is an isolated well-defined perifoveal intraretinal vascular abnormality presenting on OCT as a round hyperreflective structure with a dark lumen containing variably reflective material and is commonly associated with cystic intraretinal fluid. Conclusions and Importance: PEVAC was originally described as occurring in healthy patients, but recent observations suggest that it also appears in association with other retinal/choroidal vascular abnormalities or underlying cardiovascular abnormalities. Our case supports this hypothesis by demonstrating a PEVAC resembling lesion in a patient with multiple myeloma.
