Ocular perfusion in primary angle-closure suspect and primary angle-closure eyes without prior acute angle closure.

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
backgroundAcute intraocular pressure (IOP) spike in acute primary angle closure (APAC) decreases ocular blood flow. It is not known if this is true in primary angle-closure (PAC) eyes without prior APAC who may have had subacute attacks. Hence, we aimed to assess the ocular perfusion using optical coherence tomography angiography (OCTA) characteristics in normal, PAC suspect (PACS), and PAC eyes without APAC. MATERIALS AND
methodsThis was a prospective cross-sectional study, which determined patients' (40-80 years) optic nerve peripapillary perfusion, flux, and macular vessel density (6 mm × 6 mm and 3 mm × 3 mm) in the superficial retinal layer on OCTA.
resultsWe included 135 eyes of 135 patients (45 per subgroup). The mean age was 59.7 ± 8.3 years. The mean peripapillary perfusion was 44.4% ±1.5% in normal, 44.2% ±1.7% in PACS, and 44.1% ±1.5% in PAC eyes. There was no significant difference between OCTA parameters among normal, PACS, and PAC eyes (
conclusionSimilar OCTA parameters were seen in normal, PACS, and PAC eyes without prior APAC, suggestive of absence of vascular factors in eyes without APAC in angle-closure disease. Functional impairment, despite similar structural and perfusion parameters in PAC eyes compared to PACS eyes, may be suggestive of ganglion cell dysfunction prior to loss.
