Treating refractory corneal hydrops in a male patient with vernal keratoconjunctivitis and mental retardation: a case report.
Article in BMC ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundKeratoconus is the most common noninflammatory bilateral corneal ectasia. Vernal keratoconjunctivitis (VKC) and eye rubbing may be associated with keratoconus in children and young adults. Timely management of advanced keratoconus is important to improve visual quality. In addition, it is challenging to carry out VKC treatment with an intent to avoid the occurrence of punctate epithelial keratitis, ulceration, or corneal neovascularization on corneal grafts. CASE PRESENTATION: We report the case of an 18-year-old male patient with a long-term history of mental retardation due to megalencephaly presenting with acute onset of corneal hydrops with prominent bulging and refractory steroid-induced glaucoma of the right eye. The topography of the right eye was unavailable due to advanced ectasia, and that of the left eye revealed central steepening with inferior-superior dioptric asymmetry. According to the clinical findings, the patient was diagnosed with keratoconus. Because of progressive corneal opacity and neovascularization, the patient underwent penetrating keratoplasty (PK) with combination of interrupted and intrastromal running suturing after receiving a preoperative subconjunctival injection of bevacizumab in his right eye, followed by lower eyelid correction. After surgery, the patient was treated with 0.1% tacrolimus dermatological ointment, 0.1% cyclosporine eye drops, artificial tears, and 0.5% loteprednol for keratoplasty and VKC. Repeated education on avoiding eye rubbing was offered to the patient. Two years after PK treatment, his best-corrected visual acuity of the right eye successfully improved from hand motion at 10 cm preoperatively to 6/20 postoperatively.
conclusionsLarge-diameter PK with intrastromal suturing technique for advanced keratoconus could achieve better visual outcomes and avoid suture-related complications. In addition, tacrolimus dermatological ointment rather than tacrolimus topical eye drops or ointment showed satisfactory efficacy when combined with topical cyclosporine and steroid that no significant VKC reactivation were noted after PK.
