  • Vitreous surgery for severe ocular trauma

    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)

  • Clinical observation on diode laser choroidotomy for drainage of subretinal fluid

    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. (Chin J Ocul Fundus Dis,1998,14:202-203)

  • SEVERAL ADVANCES IN PLASTIC SURGICAL TECHNIQUES IN THE TREATMENT OF POSTBUEN DEFORMITY

    Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.

  • Vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system under topical anesthesia

    Objective To evaluate the indications, effectiveness and complications of vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system (TSV25G) under the topical anesthesia. Methods The clinical and follow-up data of 22 eyes of 22 patients undergone vitreo-retinal surgery using TSV25G under the topical anesthesia were retrospectively analyzed. All of the patients were monocular sickened, including idiopathic macular hole in 10 eyes, idiopathic macular pucker in 6, vitreoretinal traction syndrome in 4, and vitreous hemorrhage associated with branch retinal vein occlusion in 2. Peeling of epiretinal membrane and/or internal limiting membrane, intra ocular laser coagulation, air-fluid exchange and tamponiding of C3F8 were performed according to the condition of diseases. The postoperative follow-up was 1-11 months, with the mean duration of 6.4 months. The effect of analgesia, cooperation with the patients, operative effect and complications in and after the surgery were observed. Results The operations finished successfully in all of the eyes under the topical anesthesia. The operation duration ranged from 20 to 25 minutes with average of 22 minutes. The patients cooperated with the doctor well without any discomfort. Two days after the surgery, edema of the wounded conjunctiva was found, and recovered 7 days later. A light pigment dot on the surface of the sclera could be seen at the first month. The complic ations included transient increasing of intraocular pressure in 2 eyes, feather-like opacity of lens in 5 eyes, vitreous hemorrhage in 1 eye, and air-bleb under conjunctiva in 2 eyes. No other complications related with the cut were fo und. The macular hole closed in 9 eyes with idiopathic macular hole, and the other 1 had the smaller but not closed hole. Idiopathic macular pucker, vitreoretinal traction syndrome, and vitreous hemorrhage associated with branch retinal vein occlusion were cured successfully. Conclusions Vitreoretinal surgery using the TSV25G under the topical anesthesia has many advantages such as simple procedure, short operation time, micro-invasion, less complications and rapid revovery, and mainly serves simple manipulation in some simple diseases such as idiopathic macular hole, vitreo-retinal traction syndrome, and simple hemorrhage.

  • MICROSURGICAL TREATMENT OF NEUROTMESIS OF POSTERIOR INTEROSSEOUS NERVE OF THE FOREARM

    Ten cases of neurotmesis of posterior interosseous nerve of the forearm were treated with mierosurgical technique from Aug, 1988 to Oct. 1990, of which, 4 cases by autogenous nerve graft and 6 cases by direct neurosuture. Eight cases have been followed-up from 4 months to 1 year after operation concerning with satisfactory results. Some questions the diagnosis, the points for attention in operation, and the relation of the results and the time when the operation done were discussed. The comparison of the results and the recovery time between the autogenous-nerve graft and direct neurosuture was made.

  • Cryoanalgesia on Intercostal Nerves for Post-Thoracotomy Pain: A Clinical Report

    Objective To investigate the effects of cryoanalgesia for post-thoracotomy pain on the intercostal nerves. Methods Two hundred and eight patients suffering from thoracotomy were divided into three groups, according to different analgesia received respectively. Cryoanalgesia group (n = 80): cryoanalgesia on the intercostal nerves, intercostals nerves was freezed at -55 ℃ for 90 seconds ; patient controlled analgesia by vein (PCA group, n= 80): patient controlled analgesia was practiced intravenously, and control group (n = 48): Dolantin given irregularly intra-muscularly and/or tramadol orally. Severity of pain was graded by visual analogue scale. Forced expiratory volume in one second(FEV1.0) was measured and pulmonary complication after operation was compared. Results There was a statistically significant improvement in postoperative pain scores and an improvement in respiratory function tests for patients in cryoanalgesia group(X2 = 74.93,15.04,P〈0. 05). FEV1.0 in cryoanalgesia group was significantly higher than that in control group(1. 97±0.27L vs. 1. 39±0. 14 L,P〈0. 05). Pulmonary complication in cryoanalgesia group after operation was lower than that in control group (6. 25% vs. 31. 25%, P〈0. 05 ), Conclusion Cryoanalgesia on post-thoracotomy pain is very effective and may improve the respiratory function after operation.
