BackgroundIn this review, we appraised the current literature on the utility of optical coherence tomography (OCT) as a diagnostic and predictive factor for postoperative visual function outcomes in patients with sellar/suprasellar lesions with chiasmal impingement.MethodsA systematic search of PubMed, CINAHL, Scopus, and Cochrane Library was conducted following PRISMA guidelines. Included studies described diagnostic or prognostic utility of OCT in patients with sellar/suprasellar lesions with chiasmal impingement. Meta-analysis was represented as mean difference (MD) with 95% confidence intervals. Meta-regression was performed to determine predictive factors of visual outcomes.ResultsForty-eight articles were identified for final pooled analysis, representing a total of 2435 patients with compressive sellar/suprasellar lesions and 952 healthy controls. Mean age was 43.3 (11.4) years, with 1494 (48.8%) male and 1566 (51.2%) female patients. Mean retinal nerve fiber layer (RNFL) was significantly different in the study population compared with healthy controls (75.8 μ [13.2] vs. 91.4 μ [10.8], P < 0.00001). The nasal segment of RNFL had the largest mean difference (MD -9.76 [-12.39, -7.13], P < 0.0001). Visual acuity, visual field mean deviation, and visual field pattern standard deviation all showed significant differences between the study population and healthy controls as well (P < 0.0001). Meta-regressions showed significant predictive capability of preoperative RNFL in determining visual function outcome (P < 0.05).ConclusionsOur findings provide promising support for the growing evidence that OCT parameters can be utilized as both a diagnostic and prognostic tool for patients with compression of the optic apparatus. There is a need for further studies to gain a better understanding of OCTs and to improve patient outcomes.Copyright © 2022 Elsevier Inc. All rights reserved.
