Embodiment Construction

[0042] The invention described and claimed herein relates broadly to any substance inserted into the vitreous cavity that alters one of the fluids in the vitreous cavity (e.g., the natural vitreous or fluid that has replaced a removed vitreous) for the purpose of treating retinal detachment or properties (eg, viscosity) to slow the diffusion of water and / or solutes through the vitreous cavity. Current treatment for retinal detachment involves sealing the retinal tear with a packing agent such as gas or silicone oil. The present invention is fundamentally different from traditional retinal detachment repair methods. Rather than sealing a retinal hole, the present invention reduces the flow of water and / or solutes through the vitreous cavity. An unexpected result was a reduced rate of subretinal fluid accumulation. In addition, traditionally all fluid flow through the tear must be stopped to allow the retina to reattach. However, the present invention challenges this orthodox...

Abstract

A method of treating a detachment of a retina of an eye is provided. The method includes the steps of injecting a substance into a vitreous cavity of the eye, the substance slowing flow of fluid through the vitreous cavity into a subretinal space to reduce a rate of accumulation of a subretinal fluid in the subretinal space to below a rate of removal of the subretinal fluid from the subretinal space by retinal pigment epithelium; and permitting the retinal pigment epithelium to reattach the retina. The invention also includes devices for practicing the method.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Application No. 62 / 441,817, filed January 3, 2017, and US Application No. 62 / 470,324, filed March 12, 2017, each of which is incorporated herein by reference in its entirety. [0003] incorporated by reference [0004] All publications and patent applications mentioned in this specification are herein incorporated by reference in their entirety in the same manner as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. Background technique [0005] Retinal detachment is a vision-threatening condition that affects approximately 1 in 10,000 people worldwide. While there are different causes of retinal detachment, by far the most common type is due to retinal tears. This disruption of retinal integrity allows fluid from the anterior chamber to flow through the vitreous cavity to accumulate beneath the reti...
