冷冻手术学并非新发现,Scholar(1903)和Bietti(1930)早就用来使视网膜和脉络膜发生粘连,可惜当时未能设法控制冷冻的程度。只是近5年来,冷冻手术学再被应用于眼科,并且创造了新型的可以控制温度的冷冻器。一般原则;强烈冷冻引起组织脱水,电解质浓缩,细胞膜破裂,结晶体形成,淋巴管和血管淤滞。如果再降温,血液不凝固而是溶血。冷
Cryostomy is not new and Scholar (1903) and Bietti (1930) have long been used to cause adhesion between the retina and the choroid, but at the time failed to find ways to control the degree of freezing. In just five years, cryosurgery has been applied to ophthalmology and a new type of freezer has been created that can control the temperature. General principles; intense freezing causes tissue dehydration, electrolyte concentration, cell membrane rupture, crystal formation, lymphatic vessels and vascular stasis. If you cool down again, the blood does not coagulate but hemolysis. cold
