Corneal edema can cause blindness if left untreated. Actually, most eye diseases can cause blindness if the patient cannot get timely or proper treatment. Corneal edema or corneal swelling is caused by excessive fluid accumulation in the cornea potion. The symptoms of the early stage are as following: distorted or blurred vision, halos around light, discomfort in eyes, severe sensitivity to light and foreign particles. Since corneal edema can lead to blurred vision, the patient may consequently be blind if this condition continually deteriorates. Besides, corneal edema can also result in chronic eye conditions like stromal edema and intercellular epithelial edema. However, there are several treatments for corneal edema according to various causes as long as you find it out and receive medical treatment in time.
The eyes have to get oxygen and water from the endothelial cells, and the cornea provides the clear and transparent tear drops from which the eyes could get the oxygen and water. When there is excessive corneal hydration accumulated, it will lead to the corneal edema. The corneal edema presents itself as the swelling of the eyes and the inflammation of the cornea, which may be caused by the infection of viruses, complications after surgery, high eye pressure, and some other eye problems. If the corneal edema is left untreated, the condition can be deteriorate. For example, if a person gets corneal edema, he or she needs to pay attention to the prevention of eye infection, or else it would be easy for the corneal edema to develop into keratohelcosis which will leave keratoleukoma affecting the transparency of the cornea and leading to eyelight imperiment. Therefore, if the case is extremely serious, it would be possible to get blindness from the corneal edema. If people get corneal edema, they should go to the doctor's for early diagnosis, in case that the condition gets worse.
Well, in my opinion, cornea edema cannot lead to blindness, so you do not need to worry about it. Generally speaking, for corneal edema, the cornea becomes overly hydrated by accumulated fluid. Because of this disorder, it will eventually cause corneal nerves to rupture, resulting in severe pain. By the way, blurred vision will be possible too. But there is no evidence which has shown that cornea edema can lead to blindness.
