Topiramate-Induced Bilateral Acute Angle Closure in a Healthy Young Female.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Topiramate is a widely prescribed medication for epilepsy, migraine prophylaxis, and weight management, but it can rarely cause acute bilateral angle closure with myopic shift. We describe a healthy 35-year-old woman who developed sudden bilateral painful red eyes, blurred vision, and a myopic shift within one week of initiating topiramate. Examination revealed shallow anterior chambers, elevated intraocular pressure, and iridocorneal touch bilaterally. Prompt discontinuation of topiramate led to full resolution. Laser peripheral iridotomies (LPIs) were performed while the etiology was uncertain, and are not typically required in medication-induced effusion-related angle closure. This case underscores that cycloplegia and drug cessation are the key interventions, while LPI may be performed only when the underlying mechanism is unclear. This case highlights the importance of recognizing medication-induced angle closure and distinguishing it from primary pupillary-block mechanisms to ensure timely, vision-saving management.
