BACKGROUND/AIMS: Descemet stripping automated endothelial keratoplasty (DSAEK) is increasingly gaining popularity as an effective alternative to traditional penetrating keratoplasty for the treatment of endothelial diseases. However, new complications such as donor graft dislocation are seen after DSAEK. Surface venting incisions have been advocated to reduce rates of graft dislocation. We report a case of post-DSAEK fungal endophthalmitis in which the clinical course may have been influenced by the presence of surface venting incisions.
A retrospective case report.
A 72-year-old woman, who developed primary/iatrogenic graft failure after DSAEK, underwent a repeat DSAEK. Corneal venting incisions were reopened at the original sites as her first operation. Early postoperatively, she developed intrastromal opacities, which were thought to be epithelial downgrowth, but progression and increasing stromal and intraocular inflammation required anterior chamber and vitreous tap, which confirmed the presence of Candida parapsilosis, confirming the diagnosis of fungal endophthalmitis. Penetrating keratoplasty, removal of the posterior lamellar graft, removal of the posterior chamber intraocular lens implant (PCIOL) and capsular bag, and anterior vitrectomy were performed after failure of conservative antifungal therapy. Postoperatively, no recurrence of infection occurred, and the graft has remained clear at her most recent follow-up at 6 months, with a best-corrected visual acuity of 20/40.
Corneal venting incisions in DSAEK surgery may be a portal of entry for microorganisms, leading to corneal and intraocular infection, and a high index of suspicion is warranted in the presence of stromal infiltrates or inflammation at venting sites.
背景/目的:作为治疗内皮疾病的传统穿透性角膜移植术的有效替代方法,Descemet 撕囊自动化内皮角膜移植术(DSAEK)越来越受到欢迎。然而,DSAEK 后会出现供体移植物脱位等新并发症。表面通气切口已被提倡用于降低移植物脱位的发生率。我们报告了一例 DSAEK 后真菌性眼内炎病例,其临床过程可能受到表面通气切口的影响。
回顾性病例报告。
一名 72 岁女性,在 DSAEK 后发生原发性/医源性移植物失败,接受了再次 DSAEK。由于她的第一次手术,角膜通气切口在原部位重新开放。术后早期,她出现了基质内混浊,被认为是上皮下生长,但进展和持续增加的基质和眼内炎症需要前房和玻璃体抽吸,这证实了存在近平滑念珠菌,从而确诊为真菌性眼内炎。穿透性角膜移植术、后板层移植物切除、后房人工晶状体植入物(PCIOL)和囊袋切除以及前段玻璃体切除术在保守抗真菌治疗失败后进行。术后,感染未再复发,在最近的 6 个月随访时,移植物仍保持清晰,最佳矫正视力为 20/40。
DSAEK 手术中的角膜通气切口可能是微生物进入的门户,导致角膜和眼内感染,因此在通气部位出现基质浸润或炎症时,应高度怀疑。
