Anterior vitrectomy, phacoemulsification cataract extraction and irido-zonulo-hyaloid-vitrectomy in protracted acute angle closure crisis.
Article in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
purposeTo describe a modified surgical approach with anterior vitrectomy, phacoemulsification (phaco) cataract extraction and irido-zonulo-hyaloid-vitrectomy (IZHV) in protracted acute angle closure crisis (AACC). PATIENTS AND
methodsNon-comparative, retrospective case series including 21 eyes in 19 consecutive cases of protracted AACC, which persists for at least 7 days despite maximal medical and laser therapies, were included in this study. All patients underwent a modified surgical procedure with anterior vitrectomy, phaco cataract extraction, IOL implantation, goniosynechialysis (GSL) and IZHV, using modest phaco dynamic parameters with intraocular pressure (IOP) set at 30 mmHg through the procedure using Centurion® Vision System equipped with active fluidics while the anterior vitrectomy was set at 4000 or 5000 rpm. IOP and anterior chamber space were maintained through the procedure using ophthalmic viscosurgical device (OVD) injected through paracentesis whenever the Phaco or I/A probe was withdrawn from within the anterior chamber. Medical history, visual acuity (VA), IOP and anterior and posterior segment findings were recorded and compared before and after surgical treatment.
resultsThe average age of all patients was 60.05 years old, while the average period of persistent AACC was 20.05 days. Preoperatively, the average IOP of all included eyes was 44.40 ± 8.42 mmHg despite maximal topical and systemic anti-glaucoma medications and/or laser surgeries, while the average VA was 1.46 ± 0.88 (log MAR). Postoperatively, IOP was well controlled in all patients with an average IOP at 12.06 ± 3.07 mmHg without any anti-glaucoma medications at follow-ups, which was decreased significantly from that in preoperative measurements (P < 0.001). Visual acuity was improved significantly at final follow-up with an average postoperative VA at 0.74 ± 0.77 (log MAR, P < 0.001). Anterior segment inflammation was surprisingly mild with no or minimal inflammatory cells or exudates. Anterior segment configuration was resolved in all the cases. There was no recurrent IOP spike, anterior chamber shallowing or severe complications during an average follow-up of 5.38 months (ranging from 3 to 6 months).
conclusionsProtracted AACC is a complex situation while a modified surgical strategy of anterior vitrectomy, phaco cataract extraction and IZHV provides a safe and efficient solution.
