J Neural Eng:干眼症患者的福音——新型电子装置可有效刺激泪液的分泌

2015-12-14 MedSci MedSci原创

日前,科学家已研制出一种可刺激眼泪分泌的电子装置,这或可为干眼综合征患者的治疗带来新的希望,该研究结果已于12月11日发表于 Journal of Neural Engineering。

日前,科学家已研制出一种可刺激眼泪分泌的电子装置,这或可为干眼综合征患者的治疗带来新的希望,该研究结果已于12月11日发表于 Journal of Neural Engineering。

该电子装置,长16 mm,宽3-4 mm,厚1-2 mm,植入在兔眼的泪腺下。无线控制,可增加了近57% 泪液的分泌量。

“干眼症”——泪液分泌量较少导致角膜和结膜发炎,是一种最常见的眼部疾病。在美国,干眼症影响了5-6%的人口,近500万65岁以上老人患有干眼症。目前还未有有效的治疗方法。

研究人员还发现,传入神经通路(从感觉神经元到大脑的神经通路,激活泪腺分泌的发射弧)提供了一个刺激泪腺分泌泪液的更有效的方式。

研究人员最初的目的是为了刺激泪腺分泌泪液,意外发现刺激传入神经通路则会提供一种更有效且持久的分泌效果。

研究的下一个阶段将是评估改装置刺激产生的泪液的质量、体积、蛋白质和脂质含量。目前该设备正在进行临床试验以获得FDA的批准。

研究人员希望该设备可在明年上市,同时,他们还将继续研究泪液分泌发射的机制,完善该装置,并提高该设备刺激所产生的泪液的质量。
