“…That correlation was weaker and insignificant at 6 months and 1 year after intervention. These results partly match those of Ali et al (21) whose study included 30 patients who were treated for AVPM and were followed for 1 year. Their patients' VF significantly improved over time, with the most significant improvement having been achieved at 6 months after intervention, followed by additional improvement over the remaining 6 months until study closure (21).…”

Their patients' VF significantly improved over time, with the most significant improvement having been achieved at 6 months after intervention, followed by additional improvement over the remaining 6 months until study closure (21). This long duration of improvement in VF after intervention, albeit to a greater extent occurring a short time after treatment, is in agreement with the high correlation of preintervention GCC thickness recorded 2 years after intervention in our study.…”

Background:Anterior visual pathway meningiomas (AVPM) represent 2.5%–18% of all meningiomas. They may affect visual function, including visual acuity (VA) and visual field (VF). The principal modes of treatment are surgery and radiotherapy. The prognostic value of macular ganglion cell complex count (GCC) thickness has not been assessed in the literature thus far. The purpose of this study was to evaluate the prognostic value of pre-treatment optical coherence tomography (OCT) parameters (retinal nerve fiber layer and GCC) for visual outcomes in patients with AVPM.Methods:We retrospectively reviewed the medical records of all patients with AVPM who were treated in the Sheba Medical Center between 2011 and 2020. Included were patients with valid data containing preintervention OCT findings on the CIRRUS device and a minimum follow-up of 6 months. Preintervention and postintervention data on comprehensive ophthalmic examinations and OCT parameters of the affected eyes were retrieved. The correlation between preintervention OCT parameters and the visual outcome was assessed. The patients were also divided into 2 groups according to preintervention GCC (thin vs normal), and the visual outcome was compared between groups.Results:In total, 186 patients' medical records were analyzed, and 38 patients who met the inclusion criteria were included in the study (mean age at diagnosis 52.8 ± 12.2 years, 28 women). Twenty-nine patients had 1 affected eye, and 9 had bilateral insult. A higher preinterventional average GCC was associated with better VA at 6 months, 1 year, and 2 years after intervention (r = −0.5, P ≤ 0.004, 0.005, and 0.03, respectively). There was a significant correlation between preinterventional GCC and VF mean deviation 2 years after intervention (r = 0.7, P ≤ 0.001). The thinner the GCC, the more prominent was the change in VA from before intervention to 2 years after intervention (P ≤ 0.008). Correction for multiple comparisons with the Benjamini–Hochberg procedure did not change the significance of our findings.Conclusions:OCT parameters (GCC) have a predictive value in AVPM. There is strong correlation between preinterventional GCC and VA shortly after the intervention. Although a thin GCC is generally considered a negative prognostic factor, improvement in clinical parameters was also evident in patients with thin GCC. The potential of improvement despite preinterventional GCC thinning can add to the clinical discussion of the prognosis, and therefore, we recommend the patients with AVPM to undergo OCT and to be advised that GCC thinning alone should not be used as a major criterion in deciding whether treatment should be pursued.
