目的：观察视网膜大动脉瘤行25G+微创玻璃体切割术的治疗效果。

方法：收录我院自2021年1月至2024年5月因视网膜大动脉瘤致玻璃体积血或黄斑区视网膜前浓厚出血入院行25G+微创玻璃体切割术的患者40例40眼，观察手术前后最佳矫正视力(BCVA)、并发症并分析特殊病例。

结果：患者一般资料与既往文献报道相符，术后最佳矫正视力显著改善(t=9.72，P<0.01)，未见明显严重手术并发症，但需注意的是术中发现3眼继发黄斑裂孔，导致视力预后差。

结论：对于视网膜大动脉瘤引起的玻璃体积血或黄斑区视网膜前浓厚出血，25G+微创玻璃体切割术是一种安全、有效的治疗方法，但如继发黄斑裂孔则视力预后较差。

METHODS:Totally 40 patients(40 eyes)who admitted to Jinan Mingshui Eye Hospital from January 2021 to May 2024 and with vitreous hemorrhage or dense premacular hemorrhage in the macular area caused by retinal arterial macroaneurysm, underwent 25G+minimally invasive vitrectomy. Preoperative and postoperative best-corrected visual acuity(BCVA), complications, and special cases were analyzed.

RESULTS: The general patient data aligned with previous literature reports. The postoperative BCVA was significantly improved(t=9.72, P<0.01), and no significant serious surgical complications were observed. Notably, intraoperative findings revealed secondary macular holes in 3 eyes, resulting in poor visual prognosis.

CONCLUSION: For vitreous hemorrhage or dense premacular hemorrhage caused by retinal arterial macroaneurysm, 25G+ minimally invasive vitrectomy is a safe and effective treatment. Visual prognosis was excluded for secondary macular holes.
