What is it?

The retina plays an important role in providing us our vision. Sometimes we can have a retinal detachment which results in the retina pulling away from its normal position resulting in vision loss. It is also possible to have retinal holes and tears which results in a break in the retina and the accumulation of fluid resulting in a detachment occurring. This can result in someone having symptoms of blurred vision, flashes of light, a curtain veil blocking some of their vision and floaters covering their vision.

Who is at risk and how do you treat it?

Individuals who have had previous eye surgeries, high nearsightedness, or trauma to the eye or head will also increase the chance of a retinal detachment occurring. Age also plays a factor in this as the vitreous gel found in our eye shrinks overtime and can pull away from the retina resulting in a possible hole or tear. Yearly dilated eye exams are done to help detect and prevent retinal detachments from occurring. It is especially important that you see an optometrist if you have any symptoms of flashes of light or floaters in your vision. Different treatment options exist such as laser therapy, cryopexy and surgery which are chosen depending on the severity of the detachment, hole, or tear.

许多患者都担心眼前会一直出现一个漂浮的“黑点”。大多数人注意到,当注视空白的墙壁、强光或天空时,这种情况会加重。虽然这令人十分困扰,但却是患者常见的抱怨。.

眼球内充满一种称为玻璃体的凝胶状物质,它能使眼球保持形状。随着时间的推移,这种凝胶中的蛋白质会开始聚集并凝固,从而形成“飞蚊症”。.

飞蚊症可能出现在单眼或双眼。通常情况下,飞蚊症是良性的。然而,当玻璃体与视网膜层紧密粘连并牵拉视网膜时,情况就值得关注了。这可能导致视网膜裂孔、撕裂,甚至视网膜脱离。这些情况都可能损害视力,因此,如果出现这些症状,请务必立即就医。.

需要注意的症状:

  • 飞蚊症患者数量突然增多
  • 闪光
  • 遮挡视线的帘幕

如何治疗飞蚊症?

遗憾的是,除非通过手术切除整个玻璃体,否则无法去除飞蚊症。这种手术风险大于益处,通常不用于治疗这种情况。好消息是,随着时间的推移,大脑会逐渐适应飞蚊症,并能够忽略它们,从而使其不再那么令人烦恼和明显。.
