How is eye operation freezer to return a responsibility?

summary

Cryotherapy is the use of local tissue freezing, controllable destruction or resection of living tissue, treatment, also known as cryosurgery. When the tissue is frozen rapidly, the temperature drops below 0 ℃, and the tissue inside and outside the cell forms ice crystals, and the cell structure is destroyed. Then the cells dehydrated, the membrane system protein denatured, tissue defect infarction, nutritional deficiency and necrosis. It can destroy the deep and waterproof cells by freezing to reduce the intraocular pressure and relieve the pain. It is suitable for the patients who have lost their vision completely and have no hope of recovery. Glaucoma is caused by the increase of intraocular pressure, which can eventually lead to blindness. Let's take a look at the following.

How is eye operation freezer to return a responsibility?

First: cryosurgery is a kind of surgery that uses special instruments with liquid oxygen to rapidly reduce the local temperature to destroy the diseased tissue, but does no damage to the surrounding normal tissue. Generally speaking, no matter what type of glaucoma, we should consider surgery if we encounter the following situations. After drug treatment, intraocular pressure can not be controlled in the normal range of intraocular pressure patients.

Second: liquid nitrogen is a colorless and odorless liquid, not easy to burn, low refrigeration, safe to use, is currently the most commonly used in domestic dermatology refrigerant. The mechanism of cryopreservation is to use hypothermia to cause tissue degeneration and necrosis in order to achieve the purpose of treatment. The cause of glaucoma itself is unknown, and it may recur after surgery, as short as one year. So strictly speaking, glaucoma cannot be cured.

Third: after drug treatment, the intraocular pressure is still in the normal range, but the visual acuity is further decreased, the visual field is gradually reduced, the fundus is gradually expanded, and the optic nerve atrophy occurs. The patient has some systemic diseases or is unwilling to receive medication. The patient is allergic to drugs, or has serious systemic side effects, and can not persist.

matters needing attention

To prevent glaucoma, you need to live a regular life, combine work and rest with exercise, do not take part in strenuous exercise, maintain sleep quality, eat light and nutritious, and prohibit smoking, drinking, strong tea and coffee. Appropriate control of water inflow.
