Olfactory Groove Meningioma Compressing the Optic Chiasm and Optic Nerve: Improvement of Visual Functions by Surgical Intervention.
Article in Romanian journal of ophthalmology. 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
Objective: Olfactory groove meningiomas (OGMs) are rare but serious tumours that can cause visual loss. Surgical treatment of such meningiomas is critical for the recovery of visual functions. Methods: In this case report, a 62-year-old patient presented to our clinic with sudden visual loss in the right eye and underwent ophthalmological examination. Visual field (VF), retinal nerve fibre layer (RNFL) thickness test, and contrast-enhanced cranial and orbital magnetic resonance imaging (MRI) were performed. The patient was diagnosed with OGM compressing the optic chiasm and nerve, and was operated on by the neurosurgery department. Post-operative examinations were repeated, and the patient was followed up regularly. Results: Evaluations revealed a significant improvement in the patient's visual functions, including visual acuity and visual field (VF). Postoperative RNFL-thickness tests showed minimum variation. Early surgical treatment of OGMs compressing the optic chiasm and the optic nerve resulted in significant improvements in visual acuity and visual field (VF). Discussion: This case demonstrates that early surgical intervention in olfactory groove meningiomas can result in substantial improvements in visual acuity and visual fields, regardless of the initial severity of visual impairment. Even in cases with profoundly reduced vision, significant functional recovery is possible following timely decompression. Preoperative preservation of retinal nerve fiber layer (RNFL) thickness may serve as a favorable prognostic indicator for postoperative visual outcomes. The integration of MRI, VF, and OCT findings provides a comprehensive framework for diagnosis, treatment planning, and follow-up. Conclusions: According to the literature, surgical intervention is efficacious in improving visual functions and emphasizes the importance of early surgical treatment for such cases.
