玻璃體切割手術(shù)中突發(fā)單純性漿液滲出性脈絡(luò)膜脫離的影響因素的分析
[Abstract]:Objective: to investigate the main influencing factors of burst simple serous exudative choroidal detachment during vitrectomy. To investigate the correct diagnosis and effective treatment of simple serous exudative choroidal detachment. Methods: from December 2010 to December 2012, 5 eyes of patients with sudden exudative choroidal detachment during vitrectomy in our group were retrospectively analyzed. All the 5 cases underwent general patient consultation, ophthalmological examination and fundus examination before operation, and there were no signs of choroidal detachment before operation. These include 1 eye with retinal detachment, 1 eye with stage IV diabetic retinopathy, 1 eye with stage VI diabetic retinopathy (another eye has undergone vitrectomy), Traumatic choroidal laceration with ciliary body detachment in 1 eye, hypertensive vitreous hemorrhage in 1 eye. The clinical data and related examination were analyzed, and the related literature was reviewed to summarize the main factors, effective treatment methods and the application and role of triamcinolone acetonide in the course of operation in patients with burst simple serous exudative choroidal detachment. The effect of intraoperative management was evaluated by short-term and long-term (visual acuity VA), intraocular pressure (intraocular pressure IOP). Results: sudden simple serous exudative choroidal detachment was rare in vitrectomy. Its occurrence is related to the increase of blood pressure, the change of intraocular pressure, the operation mode, the operation of the other eye, the treatment of digoxin and vitrectomy through the flat part of the ciliary body, etc. A retrospective analysis of these 5 patients showed that their blood pressure increased in varying degrees during operation. The fundus manifestation of the simple serous exudative choroidal detachment that occurs during surgery is the brown-red hemispherical bulge of the entire retina that occurs during the cutting of the central axis and the surrounding vitreous body, and may be a hemispherical eminence. It can also be two or more at the same time. Four of them were diagnosed at the time of operation. They were immediately given elevated intraocular pressure above 90cmH2O, lower blood pressure, intravitreal injection of triamcinolone acetonide, and intravitreal injection of triamcinolone acetonide. The exudation disappeared within half an hour to one hour after vitrectomy, and vitrectomy was completed. The other patient, suspected of haemorrhagic choroidal detachment, closed the incision directly during the operation, and completed vitrectomy on the second day when there were no obvious signs of suprachoroidal hemorrhage in the fundus examination. The visual acuity of the patients with diabetic retinopathy stage VI was less than 0.1, and the visual acuity of the other 4 patients was between 0.2 and 0.8. The IOP of all the patients was within the normal range. Conclusion: (1) for the simple serous choroidal detachment during vitrectomy, we should take static treatment, increase intraocular pressure, lower blood pressure, and local use of corticosteroids to promote the spontaneous absorption of the fluid beneath the choroid. No further development of exudation, the above treatment stabilized the lesion, good after recovery. Postoperative visual acuity is related to the degree of primary lesion. Studies have shown that the intraoperative burst of simple exudative choroidal detachment does not affect the postoperative visual acuity as long as it is properly treated. (2) injecting triamcinolone acetonide into the vitreous cavity can reduce the exudation. Stable lesions. (3) regulating the whole body of patients, stable intraoperative blood pressure fluctuations can reduce the probability of occurrence. (4) intraoperative intraocular pressure changes too fast can increase the probability of occurrence.
