Uveitis-Glaucoma-Hyphema Syndrome Secondary to Asymmetric Intraocular Lens (IOL) Haptic Fixation: A Clinical Lesson in Mechanism-Based Diagnosis and Treatment.

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
Uveitis-glaucoma-hyphema (UGH) syndrome is a rare complication of cataract surgery caused by mechanical chafing between the intraocular lens (IOL) and adjacent uveal structures. We report a case of UGH syndrome caused by inadvertent sulcus placement of an IOL haptic. An 80-year-old man developed progressive ocular hypertension after apparently uncomplicated cataract surgery and was treated with topical antiglaucoma therapy. Approximately 30 months after cataract surgery, hyphema and decreased vision occurred, and the patient was referred to our institution. Slit-lamp examination showed mild nasal IOL decentration, while gonioscopy revealed marked inferior angle pigmentation. Anterior segment optical coherence tomography (AS-OCT) demonstrated IOL tilt and contact between the posterior iris surface and the nasal haptic. The patient underwent repositioning of the displaced haptic into the capsular bag, combined with Ahmed glaucoma valve implantation and pars plana tube insertion. After surgery, AS-OCT confirmed resolution of iris-IOL contact, and intraocular pressure was well controlled. This case may serve as a lesson for residents and young ophthalmologists who may encounter ocular hypertension of unclear origin, emphasizing the need to maintain a high index of suspicion for UGH syndrome. Careful anterior segment examination, together with AS-OCT, may help identify occult iris-IOL chafing and guide appropriate surgical management.
