The invention provides the use of fluorosilicone oil, and the application of fluorosilicone oil in preparing intraocular fillers for assistant treatment of vitreoretinal diseases. Fluorosilicone oil, as an intraocular filler, can be used to treat refractory vitreoretinal diseases, such as retinal detachment with large or multiple retinal holes, posterior retinal holes, etc. It is colorless and transparent, and its refractive index is similar to saline. It is a good optical medium. After injection into the vitreous cavity, the fundus can be clearly seen, insoluble in water, and the shape between the retinal detachment and the perfusion solution. Comparing with ordinary silicone oil, it has a larger proportion and is easier to identify; it is larger than water, and can top pressure the retinal hole sufficiently, so that it can be repositioned. After filling, it does not need special posture and is not easy to enter the retina through the hole. It has lower surface tension and higher hydrophobicity, and is easier to remove from the eye, reduce the residual rate in the operation, and further ensure the safety of patients. The introduction of fluorine atoms increases the stability of the material, and the long-term intraocular filling is more stable and not easy to emulsify.

技术介绍
视网膜脱离(retinaldetachment,RD)指视网膜神经上皮层与视网膜色素上皮层之间出现分离,是临床上常见的眼病之一,复杂性视网膜脱离是临床上严重的致盲性眼病。随着玻璃体视网膜手术的发展,许多以前无法治疗的复杂视网膜脱离可以获得视网膜解剖复位和视力提高,在复杂的玻璃体视网膜疾病中往往需要进行玻璃体的切割和置换,玻璃体替代物可以替代病变的玻璃体在眼内填充、顶压视网膜以助其复位。良好的玻璃体替代物对玻璃体视网膜手术的疗效和技术改进有着重要的意义,玻璃体替代物的研究对提高玻璃体视网膜疾病的治疗成功率有很大的帮助。自1911年Ohm首次报道在玻璃体腔注入空气修复视网膜脱离至今,人们一直在不断地寻找理想的玻璃体腔替代物。目前,玻璃体切割联合硅油填充术是治疗复杂性视网膜脱离的主要方法,硅油属于聚有机硅氧烷系列(polysiloxane),化学性质稳定,光学透明性好,表面张力较大且生物耐受性好,1962年Cibis等(CibisPA,BeckherB,OkumE,etal.The ...
