Visual field loss in Sturge-Weber syndrome and phakomatosis pigmentovascularis: Implications for glaucoma assessment.
Article in Indian journal of ophthalmology, 2026. 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
objectivesTo evaluate the patterns of visual field (VF) defects in patients with Sturge-Weber syndrome (SWS) and phakomatosis pigmentovascularis (PPV) using standard automated perimetry.
methodsThis retrospective study analyzed the clinical and VF data of patients with SWS or PPV undergoing treatment for glaucoma and had VF test data over a 27-year period. VF defects were classified as glaucomatous, neurological, combined, or unclassifiable. Statistical analyses were performed to determine factors associated with type of field defects.
resultsA total of 86 patients (172 eyes) were included, with 62 (72%) having SWS and 24 (28%) PPV. Glaucoma was present in 49.2% of SWS eyes and 91.6% of PPV eyes. Reliable VF tests were more common in SWS than in PPV ( P < 0.001). Glaucomatous defects were observed in 35.5% of eyes, 7.7% had neurological defects, and 4.1% had combined defects. Advanced field loss was the most common glaucomatous defect (54%). Eyes treated with external beam radiotherapy for diffuse choroidal hemangioma developed localized field defects mimicking glaucoma and homonymous hemianopia.
conclusionsGlaucoma remains the primary cause of VF loss in SWS and PPV, with a significant proportion of patients demonstrating advanced glaucomatous damage. Accurate interpretation of VF results is crucial for differentiating glaucomatous progression from other ocular and neurological causes in these rare phakomatoses.
