テルソン症候群の存在は、SAHの重症度を反映する予後不良の指標となりうる点が重要な臨床的特徴である。テルソン症候群を合併したSAH患者は、合併しない患者と比較して死亡率が著しく高い。系統的レビューでは死亡率43% vs 9%(オッズ比4.8)7)、別報告では28.6% vs 2.0%8)、頭蓋内圧(ICP)と関連付けた研究ではオッズ比45.0と報告されている。9) Glasgow Coma Scale(GCS)スコアが低いほど、Hunt and Hess分類およびFisher gradeが高いほどテルソン症候群を合併しやすいとされる。8,9)
硝子体手術(経毛様体扁平部硝子体切除術、pars plana vitrectomy: PPV)では、硝子体出血を除去する。TBIに続発するテルソン症候群に対する硝子体手術では、術後早期の視力改善が多くの症例で得られると報告されている2,5)。小児症例の検討でも硝子体切除術により解剖学的・機能的に良好な転帰が得られている6)。
