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.
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.

ObjectiveTo investigate the therapeutic effects of scleral buckling operations on treating longstanding retinal detachment with subretinal proliferation.MethodsThe clinical data of 36 patients (40 eyes) with long-standing retinal detachment with subretinal proliferation who had undergone scleral buckling operation were retrospectively analyzed, and the clinical features, therapeutic methods and curative effects were summarized.ResultsThe diagnosis of long-standing retinal detachment mainly based on the examination of ocular fundus. The features of the affected eyes were: flat retinal detachment, thin and transparent retina, and formation of subretinal cords. In 40 eyes undergone scleral encircling and buclking, 36 (90%) had one-off successful operation, and the visual acuities over 0.05 were found in 77.5% of the whole eyes.ConclusionsScleral encircling and buckling procedures can be used to treat long-standing retinal detachment with subretinal proliferation with fairish cured rate.

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.

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.

ObjectiveTo observe the therapeutic effect of vitrectomy combined with single-layer inverted internal limiting membrane (ILM) flap covering technique for rhegmatogenous retinal detachment (RRD) complicated with macular hole (MH).MethodsA retrospective case analysis. From January 2015 to August 2019, 29 eyes of 29 patients with RRD and MH diagnosed in the First People's Hospital Affiliated to Shanghai Jiaotong University were included in this study. There were 16 males (16 eyes) and 13 females (13 eyes). All the eyes were peripheral RRD and involving the macular area, while complicated with MH and proliferative vitreoretinopathy in stage less than C. All the eyes were examined by BCVA and OCT. The BCVA examination was performed using the Snellen visual acuity chart, which was converted into logMAR visual acuity. Before 2017, 18 eyes were treated with vitrectomy combined with ILM peeling (ILM peeling group); after 2017, 11 eyes were treated with vitrectomy combined with single-layer inverted ILM flap covering technique (ILM inverted group). The differences of age (t=0.360), onset time (t=1.235), number of holes except MH (t=0.060), RRD range (t=1.232), gas filled eyes (χ2=0.324) between the two groups were not statistically significant (P＞0.05). The average follow-up time after surgery was 4.5 months. The BCVA, retinal reattachment and MH closure at the last follow-up in the two groups were comparatively observed. U-shaped or V-shaped retina was defined as MH closure.ResultsAt the last follow-up, retinal reattachments were achieved in all the eyes. In ILM peeling group, 5 eyes (27.8%, 5/18) were completely closed in typeⅠ. In ILM inverted group, 9 eyes (81.8%, 9/11) were completely closed in typeⅠ. There was a statistically significant difference of closure rate in type Ⅰ closure between the two groups (χ2=5.968, P=0.015). The mean logMAR BCVA in ILM peeling group and ILM inverted group were 1.24±0.28 and 0.97±0.39, respectively. The difference of logMAR BCVA between the two groups was statistically significant (t=2.179, P=0.038).ConclusionVitrectomy combined with single-layer inverted ILM flap covering technique can increase the BCVA and MH closure rates in RRD patients with MH.
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.

Methods
The clinical data of 15 eyes (13 patients) with tractive retinal detachment associated with uveitis who had undergone pars plana vitrectomy from our Department were retrospectively analyzed. The patients, 6 males and 7 females, aged from 19.0 to 70.0 years, with the average of 42.8 years. The duration of the disease history was 3-15 years with the average of 7 years. In the 15 affected eyes, the visual acuity was le;hand moving before the eye in 7 eyes, 0.01-0.1 in 7, and 0.2 in 1. Vitreous opacity, proliferative vitreoretinopathy, and tractive retinal detachment were found in all of the affected eyes. All the patients had been treated with oral and topical steroid. In addition, 3 of them received oral azathioprine meanwhile. Eye drops of 1% prednisolone acetate, 1% atropine, and tropicamide were used. The inactive duration of inflammation of uveitis was 0.5-4.5 months with the average of 2.0 months. After the inflammation became inactive, pars plana vitrectomy with membrane peeling, intraocular photocoagulati,filling with C3F8 or silicon oil were performed, including 7 eyes underwent lens excision. Glucocorticoid was given to the patients orally before the operation, and systemic and ocular medication of glucocorticoid were given continuously after the operation, in whom 3 were treated with oral azathioprine meanwhile. The postoperative follow-up duration ranged from 3 to 146 months with the average of 26 months.
Results
No recrudescence of uveitis, inflammation of ocular anterior segment, or vitreous inflammation was fund in the 15 eyes. The retina reattached successfully and the visual acuity improvement in 13 eyes (86.7%), inluding 2 eyes achieved the visual acuity increased from 0.2 to 0.8 and 0.03 to 0.6, 1 eye had unchanged visual acuity (6.7%)，and 1 eye decreased from hand moving to light perception (6.7%). In the follow-up duration, 4 eyes had cataract formation and underwent cataract extraction and intraocular lens (IOL) implantation, and the visual acuity improved after the operation. Iris neovascularization and secondary hyphema were found in 1 eye. Organization membrane on the surface of rtina and tractive retinal detachment recurred in another eye.
Conclusion
Pars plana vitrectomy is effective on uveitis associated with tractive retinal detachment. Operation timing and perioperational reasonable glucocorticoid application are essential for surgery success.
