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.
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.
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).
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.
According to the literature, surgical intervention is efficacious in improving visual functions and emphasizes the importance of early surgical treatment for such cases.
嗅沟脑膜瘤（OGM）虽罕见但病情严重，可导致视力丧失。对此类脑膜瘤进行手术治疗对视力功能恢复至关重要。
在本病例报告中，一名62岁患者因右眼突然视力丧失前来我院就诊并接受眼科检查。进行了视野（VF）、视网膜神经纤维层（RNFL）厚度测试以及增强头颅和眼眶磁共振成像（MRI）检查。该患者被诊断为OGM压迫视交叉和视神经，由神经外科进行手术。术后重复进行检查，并对患者进行定期随访。
评估显示患者的视力功能有显著改善，包括视力和视野（VF）。术后RNFL厚度测试显示变化最小。对压迫视交叉和视神经的OGM进行早期手术治疗可使视力和视野（VF）得到显著改善。
本病例表明，对嗅沟脑膜瘤进行早期手术干预可使视力和视野得到实质性改善，无论初始视力损害的严重程度如何。即使在视力严重下降的病例中，及时减压后也可能实现显著的功能恢复。术前保留视网膜神经纤维层（RNFL）厚度可能是术后视力预后的有利指标。MRI、VF和OCT检查结果的综合为诊断、治疗规划和随访提供了全面的框架。
根据文献，手术干预在改善视力功能方面是有效的，并强调了对此类病例进行早期手术治疗的重要性。
