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.

偏头痛通常与剧烈头痛有关,但它们也会影响您的视力。眼部偏头痛,也称为视网膜偏头痛或视觉偏头痛,是一种独特类型的偏头痛,主要表现为视觉障碍。这意味着症状与您的眼睛和您感知周围世界的方式有关。与眼部偏头痛相关的视觉障碍是短暂的,持续时间不到一个小时。  

视觉障碍可能包括:

  • 闪烁的灯光
  • 闪烁或锯齿形线条
  • 临时盲点
  • 一只眼睛暂时失明

触发器可以包括:

  • 压力
  • 荷尔蒙波动
  • 特定食物
  • 暴露在明亮的灯光下,甚至是明显的图案下

尽管眼部偏头痛相对良性,但必须将其与可能导致类似视觉障碍(例如视网膜脱离)的更严重疾病区分开来。

如果您的视力突然发生变化,请务必立即就医。
