Predictive factors of epiretinal membrane in complicated rhegmatogenous retinal detachment tamponaded with silicone oil

AIM:To determine the incidence and predictive factors for epiretinal membrane(ERM)formation in eyes with complicated primary rhegmatogenous retinal detachment(RRD)tamponaded with silicone oil(SO).METHODS:This retrospective case-control study included 141 consecutive patients with(51 eyes)and without(90 eyes)ERM formation after primary pars plana vitrectomy(PPV)and SO tamponade for complicated RRD.The risk factors for ERM were assessed using logistic regression analysis.RESULTS:The prevalence of postoperative ERM was 36.2%(51/141).Multivariate logistic regression analysis showed that the risk factors for ERM in SO-tamponaded eyes included preoperative proliferative vitreoretinopathy[PVR;odds ratio(OR),2.578;95%confidence interval(CI)1.580–4.205,P<0.001],preoperative choroidal detachment(OR,4.454;95%CI 1.369–14.498,P=0.013),and photocoagulation energy(OR,2.700;95%CI 1.047–6.962,P=0.040).The duration of the preoperative symptoms,intraocular SO tamponade time,giant retinal tear,preoperative vitreous hemorrhage,preoperative bestcorrected visual acuity,number of breaks,quadrants of RRD,axial length,and photocoagulation points were not predictive factors for ERM formation.CONCLUSION:Preoperative PVR,choroidal detachment,and photocoagulation energy are risk factors of ERM formation after complicated RRD repair.Better ophthalmic care as well as patient education are necessary for such patients with risk factors.

Anatomical and functional outcomes after Densiron 68 heavy silicone oil tamponade for complicated retinal detachment in Chinese eyes

AIM:To evaluate the safety and efficacy of Densiron 68 heavy silicone oil (HSO) tamponade for complicated retinal detachment(RD)in Chinese eyes.METHODS:Twenty-one eyes of 21 patients with complicated RD were included in this retrospective study.All patients underwent pars plana vitrectomy with an internal tamponade using Densiron 68 HSO.Anatomical and functional results and complications were evaluated,including retinal status,visual acuity(VA),intraocular pressure(IOP),intraocular inflammation,lens opacity,and HSO emulsification.RESULTS:Allthepatients were followed up for 3mo to1y(5.8±1.16mo).Retinal reattachment was achieved in 19of 21 patients(90.5%).VA improved in 18 of 21 patients(85.7%),from 1.93 logMAR(±0.48)to 1.52 logMAR(±0.45)(P=0.001).Postoperative complications included early dispersion of HSO in 7 eyes(38.8%),cataract in 10 of 18phakic eyes(55.5%),moderate postoperative inflammation reaction in 10 eyes(47.6%),and elevated IOP in 5 eyes(23.8%),all of which were controlled by medication or by surgery.CONCLUSION:Highanatomical and functional success rates can be achieved with primary vitrectomy for complicated RD by using Densiron 68 HSO;however,it should not be ignored that Densiron 68 HSO can cause some complications in the eye.

Evaluation of macular vessel density changes after vitrectomy with silicone oil tamponade in patients with rhegmatogenous retinal detachment

AIM:To evaluate macular microvasculature changes in eyes after pars plana vitrectomy(PPV)and intraocular silicone oil(SO)tamponade for macula-off rhegmatogenous retinal detachment(RRD)using optical coherence tomography angiography(OCTA).METHODS:Totally 19 eyes(19 patients)with maculaoff RRD who underwent PPV and intraocular SO tamponade were retrospectively reviewed.The parafoveal superficial capillary plexus(SCP)vessel density(VD),deep capillary plexus(DCP)VD,choriocapillaris plexus(CCP)VD,and foveal macular thickness were evaluated using OCTA throughout 16 wk postoperatively.The values of healthy fellow eyes were used as control.RESULTS:The parafoveal SCP,DCP,and CCP VDs were significant increased over time in RRD eyes during the 12 wk postoperatively,then decreased at 16 wk postoperatively(all P<0.01).The ratios of RRD eyes and fellow healthy eyes(r/f ratios)of the SCP and DCP VDs were lower than those of the CCP VD postoperatively(all P<0.05).There were not significant differences in the r/f ratios between SCP and DCP VDs postoperatively(all P>0.05).CONCLUSION:The parafoveal SCP,DCP,and CCP VDs gradually recover over time after PPV surgery with SO tamponade.Long-time SO tamponade might decrease postoperative macular VDs.Compared to parafoveal CCP VD,the parafoveal SCP and DCP VDs were more vulnerable in RRD eyes postoperatively.

A decrease in macular microvascular perfusion after retinal detachment repair with silicone oil

AIM:To observe whether silicone oil(SO)tamponade could decrease macular perfusion after retinal detachment repair.METHODS:A prospective observational case-control study.Patients diagnosed with primary macular off rhegmatogenous retinal detachment undergoing successful retinal repair surgery with vitrectomy were strictly selected.Optical coherence tomography angiography findings were compared between SO and air tamponade groups.Two postoperative visiting points were set(1 and 3 mo).RESULTS:Totally 29 patients(29 eyes)were enrolled.Twenty cases had SO tamponade while 9 cases were with air tamponade.At the first visiting point,superficial parafoveal vessel density(PFSVD)significantly decreased in the SO group(P=0.0403),especially in the superior quadrant or superior-hemi area(P=0.0089,0.0426,respectively).Parafoveal deep vessel density(PFDVD)had no difference between the two groups.At the second visiting point,all quadrants of PFSVD reduced significantly in the SO group(P=0.0256,0.0001,0.0031,<0.0001 in temporal,superior,nasal,and inferior area,respectively),but PFDVD remained no different.In the air group,all areas of PFSVD showed significantly improving from the first visit to the second one(P=0.0324,0.0001,0.0371,0.0026,in temporal,superior,nasal,and inferior area,respectively);however,almost all quadrants of PFDVD showed no changes during this period.In the SO group,both PFSVD and PFDVD showed no obvious changes between the two visiting points.Besides,parafoveal full retinal thickness in the SO group reduced significantly at both visiting points over the air tamponade,while the foveal avascular zone area showed no difference in the two groups.CONCLUSION:After retinal detachment surgery with vitrectomy and SO tamponade,superficial macular perfusion and full retinal thickness could decrease obviously when compared to air tamponade.This reduction process could persist throughout the tamponade period.

Vitrectomy, lensectomy and silicone oil tamponade in the management of retinal detachment associated with choroidal detachment

AIM: To report the results of combined vitrectomy, lensectomy and silicone oil (SO) tamponade in treating primary rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD). · METHODS: A retrospective, consecutive and case series study of 21 subjects with concurrent RRD associated with CD was conducted. All subjects underwent a standard three -port 20G pars plana vitrectomy (PPV) with lensectomy and silicone oil tamponade. Mean follow -up time was 8 months (rang from 4 to 19 months). The primary and final anatomic success rate, visual acuity and final intraocular pressure (IOP) were recorded and analyzed. ·RESULTS: Of 21 subjects, 8 were women and 13 were men. Age at presentation ranged from 22 to 75 years (mean 57.4 years). The presenting vision ranged from light perception to 0.15. The initial IOP ranged from 3mmHg to 12mmHg (mean 6.2mmHg). All eyes were phakic except one pseudophakic. No intraocular lens was implanted during the primary surgical intervention. Fifteen of 21 (71.4%) eyes had retina reattached after one operation. Six eyes had recurrent inferior retinal detachment due to proliferation. Five of them were successfully reattached after one or more additional operations. Mean IOP at final follow -up was 15.2mmHg (range from 8mmHg to 20mmHg). One case declined for further operation. The final reattachment rate was 95.2%. Visual acuity improved in 19 (90.5%) eyes, was unchanged in 1 (4.8%) eye and decreased in 1 (4.8%) eye.·CONCLUSION: Combination of vitrectomy, lensectomy and silicone tamponade is an effective method in treating RRD associated with CD, reducing the incidence of postoperative hypotony.

Comparison of Densiron 68 and 1 000 cSt silicone oil in the management of rhegmatogenous retinal detachment with inferior breaks

AIM:To compare success rates and complications of Densiron 68 and 1000cSt silicone oil (SO) in the management of rhegmatogenous retinal detachment (RRD) with inferior breaks (IBs). METHODS:Totally 61 eyes of 61 consecutive patients with RRD with IBs were assigned to pars plana vitrectomy (PPV) with Densiron (n =31) or PPV with SO (n=30) in order of presentation. SO and Densiron removal was performed 3 months after initial surgery. Follow up visits were terminated 6 months after SO removal. ·RESULTS:With a single operation, the Densiron group showed 84% and SO 74% reattachment. With further surgery, both groups showed 90% reattachment. Complications such as cataract, raised intraocular pressure (IOP), inflammatory reaction, macular epiretinal membranes, and emulsification of SO were seen in both groups. CONCLUSION:Densiron and SO are found to have similar success rates and complications.

Episcleral macular buckling for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole

AIM: To evaluate anatomical and visual outcomes of episcleral macular buckling (EMB) for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole.METHODS: Five cases of EMB for initial failure of retinal reattachment after internal limiting membrane (ILM) peeling and silicone oil tamponade caused by myopic macular hole were retrospectively reviewed. A silicone sponge sutured directly across the macular region was performed on the silicone oil filled eyes. Silicone oil was removed no sooner than 1 month post- EMB. The duration of follow -up time after removal of silicone oil was more than 3 months.RESULTS: Retinas of five eyes were all reattached at the last follow-up. The postoperative vision ranged from counting fingers to 0.08.CONCLUSION: Anatomical results improved after EBM for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole, which was not evident for visual outcome.

Final anatomic and visual outcomes appear independent of duration of silicone oil intraocular tamponade in complex retinal detachment surgery

AIM： To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. METHODS： We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher＇s exact test and unpaired two-tailed t-test. RESULTS： One hundred and six patients（76.2%） had undergone silicone oil removal at the time of review with 96 patients（90.6%） showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity（BCVA）. Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade（P=0.0001, 〈0.0001 respectively）. CONCLUSION： Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.

Densiron 68 heavy silicone oil in the management of inferior retinal detachment recurrence: analysis on functional and anatomical outcomes and complications

AIM: To assess the efficacy and safety of a heavy silicone oil(Densiron 68) in the management of inferior retinal detachment recurrence.METHODS: A retrospective non-comparative consecutive case series study. Forty-nine cases of complex inferior retinal detachment were treated using Densiron 68 heavy silicone oil(HSO) as the endotamponade. Our main purpose was anatomic reattachment following Densiron 68 removal. Functional outcomes, rate of recurrences, the presence of inflammatory complications and intraocular pressure alterations were evaluated. RESULTS: Forty-nine patients affected by complex retinal re-detachment were recruited. The mean follow-up was 7.6(±1.5) mo. The mean best corrected visual acuity after Densiron 68 removal was 0.95 log MAR, standard error(SE: 0.068). Retinal reattachment was 61.2% after first surgery and 81.6% after second surgery. Nineteen cases(38.8%) had recurrences when intraocular heavy silicon oil was in situ, 26.3%(5 cases) of which involved the inferior retina. CONCLUSION: Densiron 68 efficiently fills the inferior retinal periphery and might lower the risk of inferior proliferative vitreoretinopathy development, in particular after a standard silicon oil tamponade that reduces the proliferative process in the upper quadrants of the retina.

Spontaneous resolution of macular edema after silicone oil removal

AIM: To investigate the macular changes in eyes filled with silicone oil(SO) and course of these changes after SO removal. METHODS: A retrospective optical coherence tomography scan review was conducted for twenty-four patients who underwent uncomplicated pars plana vitrectomy with SO tamponade for complex retinal detachments were detected with optical coherence tomography before, and one week, one month and three months after SO removal.RESULTS: Mean duration of SO tamponade was 3.6±1.0mo(range 3-7mo). Cystoid macular edema(CME) was detected in 3 eyes before SO removal. Submacular fluid was represented in 1 eye before silicone SO removal.Resolution of CME and submacular fluid was achieved1 mo after SO removal in all eyes. Mean best corrected visual acuity(BCVA) was 1.15 ±0.65(range, hand movement to 0.2) before SO removal in the eyes without macular changes. After SO removal, the mean BCVA values at 1wk and 1 and 3mo, and 0.82 ±0.23, 0.76 ±0.21,and 0.70 ±0.19, all of which were significantly better than baseline(P =0.030, 0.017, 0.006 respectively). In the eyes with macular CME and subretinal fluid the mean BCVA was significantly improved at 3mo after SO removal compared with baseline(P =0.037).CONCLUSION: Decreased visual acuity in eyes filled with SO could be caused by macular complications due to SO. CME and subretinal fluid may resolve without any additional macular surgery after SO removal.
