Total tumor resection via an appropriate surgical route may improve post-operative visual field by preserving the optic radiation (OR).
Why this matters
Post-operative visual field defects, such as homonymous hemianopsia, may occur secondary to parietal and occipital lobe tumors. It is difficult to avoid damaging the OR during gross total tumor resection in the occipital and parietal lobes.
Only a few studies have reported the pre-operative and post-operative visual field assessment after metastatic brain tumor surgery.
An appropriate surgical approach may avoid damage to the visual tract and improve the risk of visual defects after removal of metastatic brain tumors in the parietal and occipital lobes.
