Abstract

Purpose: To investigate the effect of Henle fiber layer hemorrhage (HFLh) on retinal sensitivity (RS) before and after displacement of the submacular hemorrhage (SMH) caused by retinal arterial macroaneurysm (RAM) rupture.

Methods: This retrospective study included 31 eyes undergoing vitrectomy for SMH. Eyes were grouped based on the presence or absence of HFLh (HFLh [+/-] group). RS was assessed in the fovea and in the area of the HFLh present preoperatively.

Results: The HFLh (+) and HFLh (-) groups had 21 and 10 eyes, respectively. Both groups showed improved postoperative foveal RS (both P < 0.05), which was significantly higher in the HFLh (-) group (P = 0.02). In the HFLh (+) group, RS was significantly lower in the affected eye when compared to the fellow eye (P < 0.01), whereas in the HFLh (-) group, no significant difference was noted between both eyes (P = 0.58). Despite the significant improvement in the postoperative RS in areas with preoperative HFLh (P < 0.001), it remained lower than the RS of the fellow eye (P < 0.05).

Conclusion: SMH displacement improved RS regardless of HFLh presence, although the degree of improvement was limited in the presence of HFLh.

视网膜大动脉瘤破裂致亨勒纤维层出血对视网膜敏感性的影响。

目的：探讨Henle纤维层出血（HFLh）对视网膜大动脉瘤（RAM）破裂所致黄斑下出血（SMH）移位前后视网膜敏感性（RS）的影响。方法：对31只眼进行玻璃体切除治疗SMH的回顾性研究。根据是否存在HFLh进行分组（HFLh[+/-]组）。术前在中央窝和HFLh区域评估RS。结果：HFLh（+）组和HFLh（-）组分别有21眼和10眼。两组术后中央凹RS均有改善（P < 0.05），其中HFLh（-）组明显高于HFLh（-）组（P = 0.02）。HFLh（+）组患眼RS明显低于同侧眼RS (P < 0.01)，而HFLh（-）组两眼RS无显著差异（P = 0.58）。尽管术前HFLh区术后RS有显著改善（P < 0.001），但仍低于同侧眼RS （P < 0.05）。结论：不论HFLh是否存在，SMH置换均可改善RS，尽管HFLh存在时改善程度有限。
