Visual deterioration secondary to medial sphenoid wing meningioma: systematic assessment of patient-reported outcomes and factors contributing to recovery after surgical treatment.

Abstract

Objective: Visual acuity (VA) constitutes an important outcome measure in surgery for medial sphenoid wing meningioma (SWM). This study aimed to assess the recovery of tumor-associated impairment of VA and its impact on patient-reported outcome measures (PROMs) as an indication of vision-related quality of life in patients who had undergone surgery for medial SWM.

Methods: From 2009 to 2018, 153 consecutive patients with medial SWM underwent surgical treatment at the authors' institutions. Tumor-associated VA was evaluated both on admission and during postoperative follow-up examinations, using Snellen charts. Multivariable analysis was performed to identify independent predictors for postoperative improvement of VA. PROMs were collected based on the National Eye Institute 25-Item Visual Function Questionnaire.

Results: Of patients with medial SWM, 53 of 153 (35%) experienced preoperative impairment of VA. The median preoperative duration of visual symptoms was 12 (IQR 3-17) months for the entire study cohort. Multivariable analysis revealed a preoperative duration of visual symptoms ≤ 4 months to be independently associated with postoperative improvement of VA (p = 0.009). Evaluation of PROMs indicated a superior postoperative qualitative extent in the overall health (p = 0.027) and activities of daily living (p = 0.031) categories if preoperative duration of visual impairment was ≤ 4 months.

Conclusions: The overall preoperative duration of tumor-related visual impairment significantly correlates to the extent of postoperative visual improvement as well as vision-related PROMs in medial SWM surgery. These results might aid in preoperative patient counseling and help optimize decision-making and preoperative estimation of long-term visual outcome.
