Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
【Abstract】ObjectiveTo generally analyze the current situations of clinical research and applications in early enteral nutrition (EEN) after abdominal surgery. MethodsThe published papers about the current situations of clinical research and applications in EEN after abdominal surgery were reviewed. ResultsEEN after abdominal surgery seems to be safe and effective, produces a positive nitrogen balance, keeps the integrality of structure and function of the apparatus, protects gut barrier, and reduces or prevents septic complications. ConclusionEEN may be of more benefits and will be one of the best methods of nutrition support after abdominal surgery.
Objective To observe the clinical efficacy of external-route microsurgery for retinal detachment (RD). Methods In 36 patients (36 eyes) with single rhegmatogenous RD, the silica gel piece and/or buckling bands were preplaced, and drainage of subretinal fluid, retinal cryotherapy, e xamination of locating the holes, and intraocular injection of gas were performe d under surgical microscope. The surgical effects were compared with those of ot her simultaneous 37 patients with rhegmatogenous RD who underwent surgery under binocular indirect ophthalmscope. Results The simultaneous intraoperative observation of the fundus details and the sclera through the microscope was excellent in all cases. Under the surgical microscope, the reaction of r etinal cryotherapy was clearly visible without any serious surgical sequela. The observation of reaction of retinal cryotherapy and the orientation of the holes were not affected by mild opacity of the refractive media. Retinal reattachment was achieved in 31 eyes after the primary surgery and in 3 eyes after the secon dary surgery, with the final rate of rettachment of 94%. The best-corrected vi sual acuity was ＜0.1 in 6 eyes (16.7%), 0.1-0.4 in 15 eyes (41.7%), and ≥ 0.5 in 15 eyes(41.7%). The results were similar to those of the patients underwent surgery under indirect ophthalmoscope.Conclusion The external route microsurgery is simple, convenient, reliable, and effective.

Purpose To evaluate the safety and efficacy of draining subretinal fluid with transchoroidal probing by using the traditional needling and diode endolaser probing. Methods The investigation included 70 consecutive patients(74 eyes) with rhegmatogenous retinal detachment undergoing scleral buckling surgery.Seventy cases were randomly divided into 2 groups,group A 34 cases(36 eyes)with the needle drainage procedure and group B 36 cases(38 eyes) with the diode probe respectively.The safety and efficacy were compared in between the 2 groups. Results No operative failure was found in these 2 groups.In group A,subretinal hemorrhage occurred in 3 eyes,and retinal incarceration,retinal preforation in one eye. No significant complication occurred in group B. Conclusion Diode laser drainage has the advantage in that it may reduce the incidence of operative complication with drainage.This technique might be used in any case requiring drainage of subretinal fluid especially of rhegmat ogenous retinal detachment in cases of shallow retinal detachment.

Objective To evaluate the curative effects of vitreoctomy or simple scleral buckling on retinal multiple-tear detachment associated with tracted anterior flap. Methods The clinical data of 89 eyes in 89 patients with retinal multiple-tear detachment associated with tracted anterior flap diagnosed in Jan, 1999-Jan, 2002 were retrospectively analyzed. In the 89 patients, 41 had undergone vitreoctomy and 48 had undergone scleral buckling without vitrectomy. In the duration of 2- to 36-month follow-up with the mean of (11.02±7.90) months, visual acuity, retinal reattached rate and postoperative complication were examined and the results in the 2 groups were compared. Results In 41 eyes underwent vitreocotmy, successful reattachment was found in 38 (92.7% ); visual acuity increased in 33 (80.5%), didn′t change in 6 (14.6%), and decreased in 2 (4.9%); leakage of flocculent membrane in anterior chamber occured was found in 2 (4.9%), complicated cataract in 3 (7.3%),and severe proliferative vitreoretinopathy (PVR) in 3 (7.3%). In 48 eyes underwent scleral buckling, 41 (85.4%) had success reattachment; visual acuity increased in 36 (75.0%), didn′t change in 4 (8.3%), and decreased in 8 (16.7%); leakage of flocculent membrane in anterior chamber was found in 6 (12.5%), complicated cataract in 9 (18.8 %), and severe PVR in 8 (16.7%). Conclusion There isn′t any difference of the success rate of the surgery between vitrectomy and scleral buckling for retinal multiple-tear detachment associated with tracted anterior flap.The better visual acuity and less complications are found in the vitrectomy gro up than those in the scleral buckling group.
