High myopia and non contagious, why can t I donate blood?

It is possible to donate blood for myopia, but it is not possible to donate blood for high myopia, because blood with high myopia may disrupt the balance of intraocular pressure. It may also cause vasospasm and affect vision, so people with high myopia from the perspective of protecting blood donors cannot donate blood.

In the criteria for blood donor health checkups, there are restrictions on blood donation for patients with high myopic fundus lesions, and blood donation for patients with high myopic fundus lesions may worsen due to factors such as changes in blood pressure. In order to prevent damage to the health of blood donors, it is necessary to limit blood donations from patients with fundus lesions with high myopia.

Myopic patients are not allowed to donate blood, which is also for the safety of the donor. Retinal detachment may occur if a person with myopia loses too much blood. The reason why high myopia is not recommended to participate in blood donation is usually due to the fact that during the blood donation process, due to blood pressure fluctuations, it is likely to lead to blood vessel rupture, retinal edema, retinal detachment.

However, the probability of these conditions usually occurring is relatively small, and as long as there is no problem with the fundus after the examination, you can donate blood.

Therefore, in the current national standards, there is no strict regulation that high myopia cannot donate blood. But theoretically, doctors should tell patients with high myopia diagnosed with fundus disease not to donate blood, and donors should use this as a judgment when filling out the questionnaire.

However, although there is no hard and fast rule that people with high myopia cannot donate blood, because people with high myopia are more likely to have fundus changes, considering factors such as time and cost, in most blood donation scenarios, blood collectors will discourage people with high myopia from donating blood.

In fact, mild myopia can donate blood, and high myopia may cause retinal detachment.

Although it is not contagious, it is likely to cause damage to the eyes and cause retinal detachment.

If you are highly myopic, donating blood will cause damage to your eyes, and the consequences will be irreparable.

Because they generally donate blood is not good for their own body, and they are afraid of hurting their body.

This is because some other factors are included in it that there is a certain amount of harm.

I don't think people with high myopia are physically fit, so don't donate blood.

Probably because high myopia has a certain effect on the blood.

Because it's not very good for them as human beings.

I think it's because the cerebral blood supply to myopia is relatively large, and donating blood will reduce the cerebral blood supply.

There should be a special reason why high myopia is not allowed to donate blood, do you think this is the case?

Blood donation is a matter of self-interest, many people have donated blood, everyone knows that people with blood infectious diseases cannot donate blood, so do you know why people with high myopia cannot donate blood?

Blood donation, generally understood in the mainland as unpaid blood donation, Hong Kong and Taiwan, also known as blood donation, refers to the process of donating whole blood, plasma or blood cell components by blood donors, usually the donor does not receive any remuneration, and the blood collection and supply institution presents souvenirs to the blood donor.

Donating blood can cause unstable blood pressure in the body, and people with myopia will induce some adverse symptoms due to insufficient blood supply to the eyes.

Because donating blood can increase intraocular pressure! Eye disease!!

High myopia, the eye area is often congested, and donating blood may cause insufficient blood supply to the eye, leading to further vision loss.

Generally, high myopia will be accompanied by fundus lesions, if in the case of a large amount of blood loss, it will lead to retinal detachment, resulting in danger, for the safety of blood donors, in order to facilitate the operation in actual work, generally do not check the fundus, and directly require high myopia can not donate blood.
