在高度球形有孔性视网膜脱离病例中,大量的视网膜下液体将视网膜裂孔错位,使巩膜扣带难以确切放置造成手术中不得不反复操作,冷凝裂孔的效果亦难以观察,以致脉络膜有出血的危险。手术前如能使脱离的视网膜变平,则会使视网膜脱离手术操作容易,并易获得成功。作者提出在视网膜下积液排出后,玻璃体内注入透明质酸钠(Healon)2-4ml使13例高度球形视网膜脱离的患者手术复位。作者在讨论中指出:在视网膜下液体排出后玻璃体内可注入气体或生理盐水,可使高度脱离的视网膜呈平脱离,有利于手术复位。但会形成
In highly spherical porous retinal detachment cases, a large number of subretinal fluid retinal holes will be dislocated, the scleral buckling is difficult to accurately place the operation had to repeat the operation, the effect of condensation holes is also difficult to observe, resulting in choroidal hemorrhage danger . Flattening the detachment of the retina before surgery can make the retina easier to operate and easier to achieve. The authors suggest that an intravitreal injection of 2 to 4 ml of sodium alginate after surgical effusion of the subretinal space resets the patient for surgery in 13 patients with highly spherical retinal detachment. The authors pointed out in the discussion: After the subretinal fluid is excreted into the vitreous body can be injected with gas or saline, can make a high degree of detachment of the retina were flat detachment, is conducive to surgical reduction. But will form
