Objective To probe the clinical feature and complications of extraction of silicon oil after operation of simple rhegmatogenous retinal detachment in child patients. Methods The clinical materials of 22 patients (22 eyes) of child patients (5~14 years old) and 11 cases (11 eyes) of adult patients with simple rhegmatogenous retinal detachment undergone surgical treatment and subsequent retraction of silicon oil tampon, were reviewed and analyzed retrospectively. The reasons of extraction silicon tampon, ocular complications of intrao cular silicon tamponade and the changes of visual acuity pre- and post-extraction of silicon tamponade in above 2 groups were explored. Results The main reason for the extraction and complications of silicon oil tamponade were similar in both groups. The rate of occurrence of the complications in either group rose as time went on . There was no significant difference in change of visual acuity between two groups after the extraction of silicon oil tampon. Conclusion The responses to silicon oil after the operation for simple rhegmatogenous retinal detachment is quite similar in either children or adult patients,and there is no obvious difference between child and adult patients in the results of silicon oil extraction.

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 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 noncontact 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 followup 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 noncontact 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 1338 months after the oil removal, retinal detachment recurred in 2 patients with the Wshaped holes. At the end of the followup period, 16 patients (33.3%) had U or Vshaped macular holes, and 32 patients (66.7%) had Wshaped 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.
ObjectiveTo analyze the clinical efficacy of scleral buckling surgery for rhegmatogenous retinal detachment (RRD) of 376 patients.MethodsA retrospective analysis was performed about 376 patients (391 eyes) who underwent scleral buckling surgery in Chengdu Aidi Eye Hospital from January 2018 to December 2019. There were 214 males (224 eyes) and 162 females (167 eyes). There were 15 binocular cases and 361 monocular cases. The average age was 37.16±16.36 years. The average course of disease was 3 months. There were 1 to more than 10 retina holes for all patients. Retinal breaks occur in all quadrants and at ora serrata. The preoperative average BCVA was 0.27 and the postoperative average BCVA was 0.41. Retinal detachment ranges was observed in 268 eyes in 1 quadrant, 97 eyes in 2-3 quadrants, 26 eyes in total, and 231 eyes with macular involvement. There were 376 eyes treated with scleral buckling, 9 eyes treated with scleral buckling combined with scleral encircling, 6 eyes treated with scleral encircling. The average follow-up time was 5 months. Postoperative follow-up was conducted to observe retinal reduction, BCVA, complications and patient compliance.ResultsAfter the first operation, retinal reattachmnents were successfully achieved in 375 eyes (95.91%); 16 eyes (4.09%) failed in retinal reattachmnents. Eight eyes were treated with scleral buckling again, 5 eyes were treated with vitrectomy silicone oil filling, and 3 eyes were treated with air injection. After the second operation, retinal reattachmnents were ultimately achieved in 16 eyes (100.00%). The average BCVA after operation was 0.15. Postoperative intraocular pressure increased by 45 eyes (11.51%). The intraocular pressure increased from the next day to 3 days after operation. The intraocular pressure was completely controlled 1-3 days after the treatment of topical medication and 20% mannitol. Vitreous and subretinal hemorrhage in 1 eye caused by drainage of the subscleral liquid. There was no cases withpostoperative infection.ConclusionThe retinal reattachment rate is 95.91% in 376 patients with RRD treated by scleral buckling surgery, and the visual acuity has significantly improved.
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.
The reattachment rate, macular hole (MH) closure rate, visual acuity improvement and re-detachment rate of MH retinal detachment (MHRD) of high myopia are not satisfactory owing to long axis oculi, posterior scleral staphyloma and macular atrophy. At present, minimally invasive vitrectomy surgery combined with the internal limiting membrane flap technique has become popular in the treatment of MHRD, as it can promote MH closure, and significantly improve the outcome of MHRD. However if this method can improve the postoperative visual function is still controversial. The advantage of this technique is that the loosened internal limiting membrane is applied to cover the MH surface to form a scaffold structure similar to the basement membrane. It can stimulate Müller cell gliosis more effectively, and promote tissue filling in the MH which results in MH closure. It can also promote retinal reattachment and reduce the likelihood of retinal re-detachment. This technique is expected to be a standard surgical method for the treatment of MHRD of high myopia in the future. The inserted internal limiting membrane flap technique is relatively easy to perform, induces stable flaps by simple procedures, and can be an essential complement procedure of the inverted internal limiting membrane flap technique. In order to reduce the recurrence rate in the future, it is necessary to further define the indications of different surgical methods and the predictive effects of MH healing mode on the success rate and visual function recovery.
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.

Objective To observe the clinical effect of minimally invasive vitreoretinal (MIV) surgery combined with a modified suprachoroidal drainage surgery for retinal detachment associated with choroidal detachment (RRDCD). Methods A prospective clinical study. A total of 27 patients (27eyes) diagnosed as RRDCD were recruited in this study. There were 16 males and 11 females, with an average of (53.67±14.82) years. The mean intraocular pressure (IOP) was (8.2±2.1) mmHg (1 mmHg=0.133 kPa) and best corrected visual acuity (BCVA) of minimum resolution angle logarithm (logMAR) was 1.87±0.58. All subjects underwent 23G MIV combined a modified suprachoroidal drainage surgery, which 23G stab knife and 1 ml syringe needle were used for surgery. The visual outcome, IOP, rate of retinal reattachment and complications were comparatively analyzed preoperatively and postoperatively. Results At 1 day, 10 days, 1 month and 3 months after surgery, the average of logMAR BCVA were 1.62±0.67, 1.51±0.63, 1.39±0.54, 1.32±0.56 and the mean of IOP were (13.47±5.06), (14.43±4.09), (14.89±4.30), (15.38±3.37) mmHg, respectively. There were significant differences of logMAR BCVA and IOP between before and after surgery (F=6.19, 15.21; P＜0.05). Retinal reattachments were achieved in 27 eyes (100%) at 1 day and 10 days after surgery. At 1 month and 3 months after surgery, the rate of retinal reattachment were 88.89% (24 eyes) and 85.19% (23 eyes), respectively. No severe complications such as endophthalmitis and choroidal hemorrhage were found at follow-up visits. Conclusion MIV combined with a modified suprachoroidal drainage surgery is an effective and safe treatment for RRDCD, which can promote retina tear closure, improve visual acuity.
Objective To evaluate the therapeutic effect of vitrectomy on bullous retinal detachment. Methods The clinical data of 7 patients (9 eyes) with bullous retinal detachment who had undergone vitrectomy due to useless photocoagulation were retrospectively analyzed. Bullous retinal detachment of the patients had been diagnosed by examination of slit-lamp microscope, three-mirror gonioscope, indirect ophthalmoscope, B-mode ultrasound, and fundus fluorescein angiography. All of the affected eyes underwent vitrectomy with closed triple incisions through the pars plana after release of subretinal liquid under the local anaesthesia. The cortex of vitreous body was taken out, and exsuction of subretinal liquid was carried out via retinal incision. Photocoagulation closed the incision and the effusion area of the retina, and intraocular filling matter was injected after exchange of air and liquid. The follow-up period lasted 3 months to 8 years with the average period of 47 months. Results Reattached retina was found in all of the affected eyes during the follow-up period. One eye underwent a second vitrectomy due to local retinal redetachment caused by a new retinal hole formed by the pull of pre-retinal proliferative membrane and a silicon vesicle entered the subretinal space, but the retina reattached after 1-year follow-up examination. The visual acuity impr oved in different degree after the operation in 8 eyes, but remained unchanged in 1 eye. Conclusion Vitrectomy for terminal bullous retinal detachment may promote the reattachment of retina safely and effectively, and save partial visual acuity of the affected eyes.
