RESUMEN
Purpose: To investigate the long-term visual outcome and their determinants after an operation in Thai pituitary adenoma (PA). Patients and Methods: A retrospective cohort study was conducted on PA patients who underwent surgery at Rajavithi Hospital. Baseline characteristics and visual parameters, including visual acuity (VA) and visual field (VF), were analyzed in relation to the visual prognosis outcome. The outcome was defined as VA improvement at 1-year postoperatively. Visual parameters were measured at each follow-up visit and compared. Factors for improved visual prognosis were evaluated using logistic regression analysis. Results: A total cohort of 87 patients (64.37% female), 62.07% showed improvement in visual outcome. Most improvement occurred immediately after surgery, evident at the 1-month visit. The mean follow-up time was 47.45 months (±28.49 SD), mean difference in VA improvement at 1-year was -0.56 logMAR (95% CI -0.73, -0.47). In multivariable logistic regression model, prolonged onset duration was associated with a reduced odds of improved visual outcome, with an odds ratio (OR) of 0.946 (95% CI 0.899-0.996, p = 0.034). Baseline characteristics, tumor volume, Hardy and Knops classification, and surgical approaches were not identified as significant predictors. Conclusion: Both TSS and transcranial approaches are effective for pituitary adenoma. A prompt operation is recommended for patients with prolonged onset duration, with thorough discussion on poor postoperative visual outcomes.
RESUMEN
PURPOSE: Addressing Dysthyroid Optic Neuropathy (DON) is crucial due to its debilitating impact in thyroid eye disease (TED). Prompt treatment can preserve vision. Despite lacking definitive diagnostic criteria, computed tomography's (CT) parameters are commonly used for diagnosis. However, these parameters exist without consensus on their diagnostic performance. DESIGN: Systematic review and meta-analysis. METHODS: We conducted a meta-analysis of studies assessing orbital CT diagnostic performance for DON in adults with TED. We searched various databases including Medline, PubMed, Scopus, and EMBASE, and others electronic databases, until July 2023. Evaluated CT parameters includes Barrett index (BI), fat prolapse via superior-orbital-fissure (SOF), superior-ophthalmic-vein-dilatation (SOVD), and the Nugent score. Diagnostic Test Accuracy analysis (DTA) was performed using R. RESULTS: A total of 9 articles with documented target parameters, collectively analysed 212 orbits with DON. Nugent score exhibited highest diagnostic ability with a log diagnostic odd ratio (logDOR) of 2.64 (95% CI, 2.02, 3.25). Another significant DON indicator was a BI ≥ 50%, with a logDOR of 1.97 (95% CI, 1.17; 2.77). Conversely, fat prolapse via SOF and SOVD proved less sensitive, with a logDOR of 1.42 and 1.09 respectively. Regarding the SROC curve, Nugent score and the BI have the greatest AUC. Variations in study locale, participant demographics, and measurement methods accounted for heterogeneity in meta-analysis. CONCLUSIONS: Nugent score and a BI ≥ 50% prove to be significant diagnostic parameters for DON, distinguishing them from fat prolapse via SOF and SOVD. Prioritizing these parameters can lead to prompt treatment and thus enhanced visual outcomes. PROSPERO REGISTRATION NUMBER: CRD42023446376.
