To report the early vitreous involvement in a rare familial amyloidotic polyneuropathy (FAP) mutation and associated vitreous vascular endothelial growth factor (VEGF) levels.
Observational case series.
Review of clinical, pathological, photographic, and angiographic records of two FAP siblings with severe vitreous involvement. Laboratory ELISA analysis of vitreous samples for VEGF, and DNA sequence analysis of peripheral blood for transthyretin (TTR) mutational analysis.
Two patients underwent 25-gauge vitrectomy in three eyes with marked improvement of visual acuity. Neovascularisation seen intraoperatively responded to endolaser. Analysis of vitrectomy samples for VEGF showed raised levels in all three specimens. Mutational analysis revealed an isolated Glu54Gly mutation in the transthyretin gene.
Early involvement of the vitreous occurs in a rare transthyretin mutation of FAP, with increased vitreous levels of VEGF.
报告一种罕见的家族性淀粉样多神经病(FAP)突变早期玻璃体受累情况及相关的玻璃体血管内皮生长因子(VEGF)水平。
观察性病例系列。
回顾两名严重玻璃体受累的FAP同胞的临床、病理、摄影及血管造影记录。采用实验室酶联免疫吸附测定(ELISA)法分析玻璃体样本中的VEGF,并对外周血进行DNA序列分析以检测转甲状腺素蛋白(TTR)突变。
两名患者三只眼接受了25G玻璃体切除术,视力显著改善。术中所见新生血管对眼内激光治疗有反应。对玻璃体切除样本进行VEGF分析显示,所有三个样本中的VEGF水平均升高。突变分析显示转甲状腺素蛋白基因存在孤立的Glu54Gly突变。
FAP的一种罕见转甲状腺素蛋白突变会早期累及玻璃体,且玻璃体VEGF水平升高。
