  • 25G intraocular illumination aided scleral buckling for treatment of rhegmatogenous retinal detachment

    Objective To evaluate the effectiveness and safety of 25G illumination aided scleral buckling surgery for treatment of rhegmatogenous retinal detachment (RRD). Methods This is a retrospective case control study. Fifty-seven RRD patients (57 eyes) were enrolled in this study. There were 35 males (35 eyes) and 22 females (22 eyes). The patients were randomly divided into ophthalmoscope group (29 patients, 29 eyes) and illumination group (28 patients, 28 eyes). There was no differences in the data of gender, age, onset time, logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity(BCVA) and information of retinal tears between the two groups (P>0.050). The patients in the ophthalmoscope group received operation of conventional scleral buckling with binocular indirect ophthalmoscope. The patients in the illumination group received scleral buckling surgery with the aid of intraocular illumination and noncontact wide-angle viewing system. The follow-up was ranged from 6 to 12 months. The BCVA, intraocular pressure, fundus examination and complications were observed and recorded. Results The difference of operation time between two groups was significant (t=2.124, P=0.031). In the ophthalmoscope group, 26 eyes (89.7%) achieved retinal reattachment, 3 eyes (10.3%) failed in retinal reattachment. In the illumination group, 26 eyes (92.8%) achieved retinal reattachment, 2 eyes (7.2%) failed in retinal reattachment. There was no difference of retinal reattachment rate (P=1.000). Five eyes failed in retinal reattachment, 3 eyes received sclera buckling surgery, 2 eyes received vitrectomy with silicone oil tamponade. The final reattachment ratios were both 100%. BCVA increased in both groups compared with pre-surgery BCVA (t=4.529, 5.108; P<0.001). The difference of BCVA between two groups was not significant (t=0.559, P=0.458). There was no significant difference of intraocular pressure and complications before and after surgery in both two groups (t=−1.386, −1.437; P=0.163, 0.149). The difference of intraocular pressure between two groups was not significant (t=0.277, P=0.730). Subretinal hemorrhage occurred in 1 eye in the ophthalmoscope group. There was no iatrogenic retinal break,  choroidal hemorrhage and endophthalmitis in the two groups. Conclusion 25G intraocular illumination aided buckling surgery for treatment of RRD is fast, safe and effective.

  • Mission inheritance in petri dishes: exploration of course-based ideological and political education construction in clinical microbiology laboratory technology

    The teaching team of the Department of Laboratory Medicine, West China School of Medicine, Sichuan University takes scientific spirit, craftsmanship spirit, and medical humanities spirit as the goal, combines the core knowledge of clinical microbiology laboratory technology course with cases of coronavirus disease 2019 prevention and control, drug resistance monitoring, and scientists’ deeds, and adopts strategies such as hot debate and special report to achieve the integration of knowledge and value. The actual effectiveness of this model has been verified through the assessment of students’ abilities and values. This article introduces the course-based ideological and political education construction mentioned above, aiming to explore the integration path of course-based ideological and political education in the clinical microbiology laboratory technology, and construct a new teaching model that combines professional competence and value guidance.

  • 黄斑裂孔手术治疗中内界膜的处理

    黄斑裂孔手术中内界膜(internal limiting membrane,ILM)剥除的有效性尚有许多争议。目前,多数研究者提倡进行ILM的剥除。因ILM的剥除提高了黄斑裂孔手术的解剖成功率,并使视力明显提高,且缩短了手术后俯卧位的时间;但在手术适应证的选择上还存在分歧。文献报道的资料由于标准不同,难以进行统计学方面比较。只有前瞻、随机、双盲、足够病例的临床试验,进一步加强临床追踪以及随着黄斑裂孔手术方式、技巧的不断改进完善,进一步验证ILM剥除的利弊,才能对其做出全面客观的评价。 (中华眼底病杂志,2003,19:201-268)

  • Clinical study on the treatment of old retinal detachment by scleral buckling procedure

    Objective To observe the therapeutic effect of scleral buckling procedure on old retinal detachment. Methods The clinical data of 42 patients (46 eyes), including 24 males (27 eyes) and 18 females (19 eyes), with old retinal detachment treated by scleral buckling procedure in our department were retrospectively reviewed. The duration of the disease ranged from 1 month to 2 years. All the patients were with rhegmatogenous retinal detachment and combined with mainly predominantly-subretinal proliferative vitreoretinopathy (PVR) (stage C), including stage C1 of PVR in 16 eyes (34.8%), stage C2 in 19 eyes (41.3%), and stage C3 in 11 eyes (23.9%). Scleral buckling was performed on 13 eyes (28.3%) and cerclage combined buckling on 33 eyes (71.7%). Sterile air was injected into 36 eyes (78.3%) during the operation, and C 3F 8 was introvitreal injected into 7 eyes (15.2%) after the operation. Results The follow-up duration was from 6 months to 1 year (mean 7.3 months). Retina was completely reattached in 31 eyes (67.4%), and was alleviated obviously in 12 eyes (26.1%). The subretinal fluid increased after the operation with un-reattached retina and vitrectomy was performed in 2 eyes. One eye underwent vitrectomy due to the development of PVR. After the first operation, the curative ratio of retinal detachment was 67.4%, and effective ratio (cure and alleviation) was 93.5%. The visual acuity improved in 28 eyes (60.9%), kept no change in 11 eyes (23.9%), and decreased in 7 eyes (15.2%). Conclusion Reattachment of retina and improvement of visual acuity can be achieved in some degree in some patients with old retinal detachment who undergo simple scleral buckling procedure without vitrectomy.

  • The therapeutic effect of combined surgery of anterior and posterior segment and silicon oil tamponade on macular hole retinal detachment in eyes with high myopia

    Objective To observe the therapeutic effect of combined surgery of anterior and posterior segment and silicon oil tamponade on macular hole retinal detachment in eyes with high myopia.Methods The clinical data of 48 high myopia patients (48 eyes) with macular hole retinal detachment were retrospectively analyzed. Retinal detachment was mainly at the posterior pole; macular hole was confirmed by noncontact Hruby lens and optical coherence tomography (OCT). Phacoemulsification combined with pars plana vitrectomy and silicon oil tamponade were performed to all patients, of which 41 had undergone internal limiting membrane peeling, and 23 had intraocular lens implanting. The oil had been removed 3.5-48.0 months after the first surgery and OCT had been performed before the removal. The followup period after the removal of the silicon oil was more than 1 year.Results The edge of the macular hole could not be seen under the noncontact Hruby lens 1 week after the surgery in all but 5 patients, and the visual acuity improved. The silicon oil had been removed in all of the 48 patients; the OCT scan before the removal showed that the closed macular holes can be in U shape (8 eyes), V shape (6 eyes) or W shape (23 eyes). About 1338 months after the oil removal, retinal detachment recurred in 2 patients with the Wshaped holes. At the end of the followup period, 16 patients (33.3%) had U or Vshaped macular holes, and 32 patients (66.7%) had Wshaped macular holes. The rate of retinal reattachment was 100%.Conclusion Combined surgery of anterior and posterior segment and silicon oil tamponade is effective on macular hole retinal detachment in eyes with high myopia.
