Patient Prefer Adherence 2023; 17:3307-3329. [PMID: 38106365 PMCID: PMC10725633 DOI: 10.2147/ppa.s427209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 12/06/2023] [Indexed: 12/19/2023] Open
Abstract
Diabetic macular edema (DME) is a common sight-threatening complication of diabetic retinopathy (DR) and the leading cause of severe visual impairment among the working-age population. Several therapeutic options are available for the management of DME, including intravitreal corticosteroids. They have been traditionally used as second-line treatment, due to the risk of intraocular pressure increase and cataract-related adverse events. However, attention has recently been focused on the primary or early use of intravitreal corticosteroids, due to growing evidence of the crucial role of inflammation in the pathogenesis of DME. Furthermore, intravitreal steroid implants offer the additional advantage of a longer duration of action compared to anti-vascular endothelial growth factor agents (anti-VEGF). This review aims to summarize the available evidence on the efficacy and safety profile of dexamethasone (DEX) intravitreal implant, with a specific focus on clinical scenarios in which it might be considered or even preferred as first-line treatment option by adequate selection of patients, considering both advantages and possible adverse events. Patients with contraindications to anti-VEGF, DME with high inflammatory OCT biomarkers, pseudophakic patients and phakic patients' candidates to cataract surgery as well as vitrectomized eyes may all benefit from first-line DEX implant. Additionally, DME not responders to anti-VEGF should be considered for a switch to DEX implant and a combination therapy of DEX implant and anti-VEGF could be a valid option in severe and persistent DME.

Abstract
Vitreous hemorrhage (VH) is the main complication of proliferative diabetic retinopathy and remains the primary indication for vitrectomy in diabetic patients. The objective of our study is to compare our medical and surgical management of VH with data from the literature and to report the functional results of our series. We studied a series of 284 cases collected over 2 years in two tertiary care centers. In our series, 90.1% of patients had type 2 diabetes, and 70% had glycosylated hemoglobin greater than 7.5%. On fundus examination, 35.2% presented with stage 1 VH, 42.6% with stage 2, 3.6% with stage 3 and 5.2% with stage 4. Ocular ultrasound performed when fundus exam was difficult diagnosed an associated tractional retinal detachment in 8.8% of patients. Medical treatment was sufficient in 77.8% of patients, while 22.2% of our patients underwent vitrectomy, argon laser endophotocoagulation and postoperative anti-VEGF injection. Peeling of tractional fibrovascular membranes and or associated epiretinal membranes was performed in 69.8% of cases. Iatrogenic tears were noted in 11.8% of patients. In this study, 31.5% of patients underwent intraocular gas tamponade, while 23.8% of cases underwent silicone oil tamponade. Postoperative visual acuity improved by at least 2 lines in 60% of our patients, and the VH recurred in 24.2% of cases after surgery.

Abstract
Purpose To assess the optimal time of intravitreal conbercept (IVC) treatment prior to pars plana vitrectomy (PPV) in patients with severe proliferative diabetic retinopathy (PDR). Method This study was exploratory in nature. Forty-eight consecutive patients (48 eyes) with PDR were divided into four groups according to different IVC times (0.5 mg/0.05 mL) before PPV: group A (3 days), group B (7 days), group C (14 days), and group D (non-IVC). Intraoperative and postoperative effectiveness were assessed, and vitreous VEGF concentrations were detected. Result For intraoperative effectiveness, groups A and D had a higher incidence of intraoperative bleeding than groups B and C (P = 0.041). Furthermore, groups A-C required less surgical time than group D (P < 0.05). For postoperative effectiveness, group B had a significantly higher proportion of visual acuity that improved or remained unchanged than group D (P = 0.014), and groups A-C had lower proportions of postoperative bleeding than group D. The vitreous VEGF concentration of group B (67.04 ± 47.24 pg/mL) was significantly lower than that of group D (178.29 ± 110.50 pg/mL) (P = 0.005). Conclusion IVC treatment that was administered 7 days preoperatively was associated with better effectiveness and a lower vitreous VEGF concentration than its administration at other time points.

A pilot study of viscoelastic agent to prevent recurrent vitreous hemorrhage after vitrectomy for proliferative diabetic retinopathy. BMC Ophthalmol 2022; 22:509. [PMID: 36550421 PMCID: PMC9783745 DOI: 10.1186/s12886-022-02666-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 11/01/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND To evaluate the possibilty of preventing recurrent vitreous hemorrhage (RVH) after vitrectomy in proliferative diabetic retinopathy (PDR) patients with unabsorbed vitreous hemorrhage (VH) by intravitreal injection of viscoelastic agent (VA) at the end of the surgery and compared its effect with triamcinolone acetonide (TA). METHODS This was a pilot prospective, observational study. PDR patients with VH who underwent vitrectomy were assigned to 3 groups according to the tamponade applicated at the end of the surgery, including VA group (intravitreally injected 1 ml VA if the retina was prone to bleed during the operation), TA group (intravitreally injected 2 mg TA when there was much exudates), or balanced salt solution (BSS) group (no tamponade). Then postoperative follow-up was performed routinely until 6 months after surgery. The primary outcome was the incidence of RVH, secondary outcome were the best-corrected visual acuity (BCVA) and introcular pressure (IOP). Cataract formation and other complication were also assessed. RESULTS A total of 68 eyes, from 68 patients, were included. 18,18,32 eyes were enrolled in the VA group, TA group and BSS group, respectively. The integral incidence of RVH after vitrectomy was 5.6%, 5.6% and 12.5% respectively (P = 0.602). There was no early RVH in VA or TA group, whereas 3 early RVHs were identified in BSS group, however there was no significant difference (P = 0.171). Every group had one late RVH case. In all groups, final BCVA showed significant improvement compared to baseline. BCVA at any postoperative visit showed no significant differences among 3 groups. Mean IOP was higher 1 week after surgery in VA group compared with the other groups; however, in other times the differences were not significant. No cataract formation and other complication was noted in 3 groups. CONCLUSION Intravitreal injection of VA or TA at the end of vitrectomy for PDR patients with unabsorbed VH tend to reduce the incidence of early RVH after vitrectomy similarly. As VA was preferred to applicate in the eyes that were prone to bleed, intravitreal injection of VA at the end of vitrectomy might be a promising method for preventing RVH in PDR patients.

Abstract
Purpose: To investigate the different tamponade effects of intravitreal silicone oil (SO) and perfluoropropane gas on the retinal structure and vasculature in proliferative diabetic retinopathy (PDR) patients. Methods: Thirty-eight eligible patients (47 eyes) with PDR requiring pars plana vitrectomy (PPV) were enrolled in the prospective observational study. Subjects were divided into two groups after PPV: SO group subjects underwent SO tamponade, whereas Gas group subjects underwent perfluoropropane gas tamponade. The primary outcomes of this study were longitudinal changes in retinal structure and vasculature between 10 and 90 days after the operation. Secondary outcomes were longitudinal changes in peripapillary retinal nerve fiber layer (pRNFL) thickness between 10 and 90 days after the operation in each sector. Results: Thirty-six eyes of 27 patients with a median age of 56.6 ± 9.8 years completed follow-up and were statistically analyzed. No significant difference in demographics or clinical characteristics was found between the two groups. Eyes in the SO group had a statistically significant decrease in pRNFL thickness at 90 days after PPV (p < 0.001), and there was a significant intergroup difference compared with the Gas group (p = 0.001), except for the temporal sector. Eyes in the Gas group had a statistically significant increase in parafoveal vessel density (VD) of the superficial vascular complex (SVC) at 90 days after PPV (p = 0.023), although there was no significant intergroup difference. The type of tamponade, changes in full retina thickness, and parafoveal SVC VD showed a significant correlation with changes in pRNFL thickness (all p < 0.05). Conclusion: SO tamponade resulted in a significantly greater decrease in pRNFL over 90 days than gas tamponade in patients with PDR. In addition, the change in the pRNFL was significantly correlated with changes in full retina thickness and SVC VD after the operation.

Abstract
PURPOSE Silicone oil intraocular retinal tamponade is a useful adjunct to pars plana vitrectomy (PPV) in the treatment of complex vitreoretinal conditions. Siluron2000, a modified silicone oil product containing an additional small, high molecular weight and low viscosity, very-long-chain silicone molecule, was developed to reduce post-operative silicone oil emulsification, a non-infrequent complication that occurs with low molecular weight silicone oil. This study was designed to assess the safety and efficacy of long-term Siluron2000. PATIENTS AND METHODS This was a single-center, retrospective, observational study. All consecutive patients undergoing PPV with intravitreal Siluron2000 injection between January 2017 and September 2019 with at least 6-month follow-up were identified based on billing codes. RESULTS A total of 57 eyes of 57 consecutive patients comprising 51 cases of proliferative vitreoretinopathy and 6 cases of recurrent full thickness macular hole were included. Median follow-up was 18 months. Emulsification occurred in 9 patients (15%). Retinal re-attachment was achieved in 47 patients (82%). The median time without silicone oil emulsification was 17 months. Of the cases with residual retinal detachment (RD) despite intravitreal Siluron2000, 4 (7%) were total RDs and 6 (10%) were inferior RDs with attached macula. The most common complications were glaucoma 12 (21%), cataract 11 (19%), and epiretinal membrane 2 (3.5%). There was no association between the duration of Siluron2000 and visual outcomes. CONCLUSION Siluron2000 is an effective long-term tamponade agent in the treatment of complex vitreoretinopathy. Visual and anatomical outcomes are similar to those reported with higher mw silicone oil tamponade agents but with a lower emulsification rate.

Abstract
PURPOSE Intraoperative subretinal anti-vascular endothelial growth factor (VEGF) injections have been used clinically in some case, but the pharmacokinetic characteristics have not yet been determined. In this pilot study, we investigate the pharmacokinetic parameters of anti-VEGF agents by intraoperative subretinal or intravitreal injection in silicone oil (SiO)-filled eyes of patients with proliferative diabetic retinopathy (PDR). METHODS Randomized controlled trial including 13 patients (16 eyes) with PDR underwent pars plana vitrectomy (PPV) with SiO tamponade and randomly received a subretinal (8 eyes) or intravitreal (8 eyes) conbercept injection (0.5 mg/0.05 ml) intraoperatively. Aqueous humour (AH) was obtained on the 1st, 3rd, 7th, 10th, 14th, 21st and 28th day after the injection. Drug concentrations in the AH were determined by enzyme-linked immunosorbent assay (ELISA). The last best-corrected visual acuity (BCVA) was examined 6 months postoperatively. RESULTS The clearance rate of anti-VEGF agents by subretinal injection was reduced in vitrectomized eyes with SiO tamponade (p < 0.05). With the same drug dose, subretinal injection (5.49 ± 6.11 μg/ml) resulted in higher drug concentrations in the AH when compared with intravitreal injection (0.42 ± 0.46 μg/ml, p = 0.001) 4 weeks after the treatment. The mean residence time last (MRT0-t ) by subretinal injection (11.57 ± 0.83 days) was significantly longer than the mean MRT0-t by intravitreal injection (7.10 ± 1.00 days, p < 0.001). A self-paired analysis showed that subretinal injection led to the BCVA improvement by +28.59 letters 6 months postoperatively (p = 0.028) while the BCVA did not improve significantly by intravitreal injection (p = 0.715). CONCLUSIONS The drug maintenance phase was prolonged by intraoperative subretinal injection in SiO-filled eyes of PDR. The results suggest that subretinal injection might be a valuable treatment option for the management of PDR.

Abstract
Background We aimed to analyse multiple factors in the prediction of risk of postoperative recurrent vitreous haemorrhage (RVH) for non-clearing vitreous haemorrhage in patients with diabetic retinopathy (DR) who underwent sutureless vitrectomy with 23- (23G) or 25-gauge (25G) narrow-gauge systems. Methods A retrospective consecutive case series design was used. DR patients who underwent sutureless vitrectomy for non-clearing vitreous haemorrhage between June 2017 and October 2019 were enrolled. All operations were performed at a tertiary hospital. Patient demographics and risk factors, including age, gender, duration of diabetes, preoperative fasting blood sugar levels (FBSL), systolic blood pressure (SBP), serum creatinine (Cr), urea, triamcinolone acetonide (TA), electrical coagulation, air-fluid exchange, pan-retinal photocoagulation status (PRP), anti-vascular endothelial growth factor drug (anti-VEGF), and other factors, were recorded. Patients were divided into two groups based on the timing of their postoperative RVH: immediate postoperative RVH (within 2 weeks after operation) and delayed postoperative RVH (beyond 2 weeks after operation). Results Overall, 167 eyes (167patients) were enrolled. Seventy eyes were underwent 23G and 25G sutureless vitrectomy performed in 97 eyes, respectively. Postoperative RVH developed in 18 eyes (25.7%) in Group 23G and in 20 eyes (21.6%) in Group 25G (P = 0.540). Of these, 3 eyes (4.3%) had severed RVH in Group 23G compared with 5 eyes (5.2%) in Group 25G (P = 0.584). Delayed postoperative RVH occurred in 6 eyes (8.6%) in Group 23G and 8 eyes (8.2%) in Group 25G (P = 0.789). A binomial logistic regression analysis revealed that age, duration of diabetes, and Cr level were significantly associated with RVH in both Group 23G (P < 0.05) and Group 25G (P < 0.05). Conclusions The incidence and severity of RVH were 25.7 and 4.3%, respectively, in Group 23G and 21.6 and 5.2%, respectively, in Group 25G. Thus, the 23G sutureless vitrectomy approach was as safe as the 25G sutureless vitrectomy approach for treating vitreous haemorrhage in patients with DR. A younger age, shorter duration of diabetes, and higher Cr levels were risk factors for postoperative RVH in sutureless vitrectomy.

Abstract
AIM Main failure of diabetic tractional retinal detachment (TRD) surgery is the development of proliferative vitreoretinopathy (PVR), causing higher re-detachment rates. We investigated whether the use of dexamethasone (DEX) implant at the end of pars plana vitrectomy (PPV) with silicone oil tamponade might have an impact on these outcomes. DESIGN Comparative, nonrandomized, retrospective study. PARTICIPANTS A total of 148 eyes from 148 patients that underwent PPV with silicone oil tamponade for diabetic TRD (with DEX implant, n = 52; without DEX implant, n = 96). METHODS Consecutive patients' records were reviewed for time between TRD diagnosis and surgery; lens status before surgery and after 6, 12, and 24 months; retina attachment rate after primary PPV; change in postoperative PVR severity; rate of re-detachment at 6, 12, and 24 months; use of IOP lowering treatment after 6, 12, and 24 months; surgery details; intra- and postoperative complications. Correlations between outcome measures, postoperative PVR severity, and re-detachment rates were analyzed. MAIN OUTCOME MEASURES Change in postoperative PVR severity and retinal re-detachment rates with and without the adjuvant use of DEX implant. RESULTS Retinal re-detachment rates were significantly higher in the group of patients that did not receive DEX implant [11/96 (11.5%) vs. 0/52 (0%), p = 0.049; 11/84 (12.9%) vs. 4/52 (7.7%), p = 0.007; 14/71 (19.7%) vs. 5/52 (10%) p < 0.001 at 6, 12, and 24 months, respectively]. PVR severity correlated with retinal status at 12 and 24 months (p = 0.018 and p = 0.027, respectively). The difference in PVR severity between the two groups was statistically significant at 6, 12, and 24 months (p < 0.001). CONCLUSIONS DEX implant at the end of PPV in patients with diabetic TRD improves PVR severity and decreases re-detachment rates. This should be considered as an option in the customized treatment of TRD.

Abstract
PURPOSE To examine outcomes of 23-gauge (23G) pars plana vitrectomy (PPV) for complex diabetic tractional retinal detachment (TRD) in Chicago's Cook County Health and Hospitals System (CCHHS). MATERIALS AND METHODS This is a retrospective noncomparative study of diabetic TRD cases that underwent PPV at CCHHS. Primary retinal reattachment rate, visual function, and postoperative complications were analyzed. RESULTS Sixty nine consecutive cases were included. Primary reattachment and final attachment were achieved in 68/69 eyes (98.6%). Secondary retinal detachment was noted in 1 eye (1.4%). Vitreous hemorrhage requiring repeat PPV developed in 5 eyes (7.2%) and reoperation due to other complications was required in 4/69 eyes (5.8%). Perfluoropropane (C3F8) gas tamponade was used in 91.3% of eyes and silicone oil in 8.7% of eyes. Mean LogMAR visual acuity significantly improved from 1.84 ± 0.61 to 0.93 ± 0.66, (P<0.0001). Vision was stabilized or improved in 66 eyes (95.7%). Visual acuity of 20/200 or better was achieved in 49/69 eyes (71.0%) and 20/50 or better in 16/69 eyes (23.2%). CONCLUSIONS Even in patients with severe and advanced diabetic TRD pathology and unique demographics as seen in CCHHS, modern vitrectomy techniques can provide excellent anatomical and visual outcomes.

Abstract
PURPOSE To evaluate visual and anatomical outcomes of diabetic tractional retinal detachment repaired with pars plana vitrectomy. METHODS Operative records were used to retrospectively identify all patients with tractional retinal detachments secondary to proliferative diabetic retinopathy surgically repaired with pars plana vitrectomy between November 1, 2009, and January 1, 2015 at the LAC + USC (Los Angeles County + University of Southern California) Medical Center. RESULTS A total of 403 eyes with diabetic tractional retinal detachment in 359 patients were included. Successful reattachment of the retina was achieved in 87.6% of eyes after one surgery and 92.6% of eyes at the final follow-up. Best-corrected visual acuity at the final follow-up improved two or more lines in 56.3% of eyes, was stable in 23.8% of eyes, and decreased two or more lines in 19.9% of eyes. Eyes repaired with 23-gauge and 25-gauge vitrectomy systems had similar success rates as eyes treated with 20-gauge instrumentation (P = 0.73). Eyes receiving silicone oil tamponade had lower single-surgery reattachment rates (77.6% vs. 87.6%; P = 0.013), lower reattachment rates at the final follow-up (85.7% vs. 92.6%; P = 0.048), and higher rates of vision loss (34.7% vs. 19.9%; P < 0.0001) but were more likely to have concurrent rhegmatogenous detachment (47.0% vs. 21.3%; P < 0.0001) and macula involving detachment (74.5% vs. 60.0%; P < 0.0001). CONCLUSION In this large, single-center retrospective study of patients with advanced diabetic tractional retinal detachment, vitrectomy achieved excellent anatomical outcome and improved or stabilized vision in 80.1% of eyes. Smaller gauge vitrectomy systems were found to have similar outcomes to 20-gauge instrumentation.

Abstract
Tractional retinal detachment is an end-stage form of diabetic retinopathy that occurs when contractile forces in the vitreous and neovascular tissue lead to the detachment of the neurosensory retina. We review the literature related to the management of this disease. Preoperative planning includes appropriate patient selection, diagnostic and prognostic imaging, and medical optimization with reduction of systemic risk factors. Use of antivascular endothelial growth factor for preoperative treatment has had significant benefits for tractional retinal detachment repair in improving surgical efficiency and outcomes. Advances in microsurgical instrumentation are discussed, with attention to small-gauge vitrectomy with improved flow dynamics, viewing strategies, and lighting allowing bimanual surgery. Special emphasis is placed on bimanual surgical technique, choice of tamponade, and the avoidance of iatrogenic damage. Complications and special considerations are further explored. Based on our compilation of relevant literature, we propose a surgical algorithm for the management of these complex patients.

Abstract
Twenty-five percent of diabetes-related vision loss stems from complications of proliferative diabetic retinopathy (PDR). Panretinal photocoagulation has been the preferred treatment of high-risk PDR for decades and more recently intravitreal injections of drugs that inhibit the actions of vascular endothelial growth factor have become popular. But despite these treatments PDR may progress uncontrollably to advanced pathologies such as traction retinal detachments (TRDs), combined traction/rhegmatogenous retinal detachments (TRD/RRDs), vitreous hemorrhages, rubeosis iridis, and traction maculopathies, which produce mild-to-severe loss of vision. TDR have long been the most common indication for PDR-related vitreoretinal surgery. Vitrectomy surgery is indicated for recent (<6 months duration) TRD involving the macula, progressive TRD that threatens the macula, and recent data suggest that chronic macula-involving TRDs (>6 months duration) may also benefit. Combined TRD/RRD represents a particularly challenging surgical condition but advances in surgical instrumentation, dissection techniques, and post-operative tamponade have produced excellent success rates. The recent development of small-gauge vitrectomy systems has persuaded most surgeons to switch platforms since these appear to produce shorter surgical times and quicker post-operative recoveries. Pre-operative injections of bevacizumab are frequently administered for persistent neovascularization to facilitate surgical dissection of pre-retinal fibrosis and reduce the incidence of post-operative hemorrhages. Recent trends toward earlier surgical intervention and expanded indications are likely to continue as surgical instrumentation and techniques are further developed.

Abstract
PURPOSE To assess the risk and benefit of pars plana vitrectomy for diabetic macular edema. METHODS The authors conducted a systematic literature review using PubMed, EMBASE, Web of Science, and Cochrane Central Database of Controlled Trials until September 2014. The population was patients with diabetic macular edema, intervention vitrectomy, comparator macular laser or observation, and efficacy outcome visual acuity and central retinal thickness. Safety outcomes were intraoperative and postoperative surgical complications. The efficacy meta-analysis included only randomized controlled trials. The safety analysis included prospective, retrospective, controlled, and uncontrolled studies. RESULTS Five studies were eligible for the efficacy meta-analysis (n = 127 eyes) and 40 for the safety analysis (n = 1,562 eyes). Combining follow-up intervals from 6 to 12 months, the meta-analysis found a nonsignificant 2 letter visual acuity difference favoring vitrectomy, and a significant 102 μm greater reduction in central retinal thickness favoring vitrectomy, but a post hoc subgroup analysis found that a 6-month central retinal thickness benefit reversed by 12 months. The most frequent complications were retinal break (7.1%), elevated intraocular pressure (5.2%), epiretinal membrane (3.3%), and vitreous hemorrhage (2.4%). Cataract developed in 68.6% of 121 phakic eyes. CONCLUSION Vitrectomy produces structural and functional improvements in select eyes with diabetic macular edema, but the visual gains are not significantly better than with laser or observation. No major safety concerns were identified.

Abstract
PURPOSE: To compare the clinical outcomes and complications between 23-G and 25-G vitrectomy in patients with diabetic vitreous hemorrhage (VH). MATERIALS AND METHODS: A retrospective comparative study comprising 69 eyes (36 eyes in 23-G group and 33 eyes in 25-G group) of 65 patients who underwent vitrectomy with air tamponade for diabetic vitreous hemorrhage (VH) with at least 6 months of follow-up was conducted. RESULTS: There were no significant differences between the two groups in age, gender, bilaterality, type of diabetes, presence of hypertension, lens status, and previous argon laser photocoagulation state (P > 0.05). Best-corrected visual acuity (BCVA) of both groups at postoperative 1 month logarithm of the minimum angle of resolution (logMAR) (1.06 ± 0.99, 0.90 ± 0.96), 3 months logMAR (1.07 ± 0.93, 0.83 ± 0.85), and 6 months logMAR (1.03 ± 0.89, 0.83 ± 0.85) significantly improved from the preoperative BCVA logMAR (2.03 ± 0.83, 2.15 ± 0.99) for 23-G group, 25-G group, respectively (P < 0.0001). There was no significant difference in BCVA between the two groups preoperatively and at 1, 3, and 6 months postoperatively (P = 0.566, 0.506, 0.333, and 0.445, respectively), incidence of intraoperative wound suturing (21.4%, 15.2%), postoperative hypotony (0.0%, 0.0%), early postoperative VH (POVH) (11.1%, 15.2%), late POVH (5.6%, 0.0%), retinal detachment (2.8%, 6.1%), neovascular glaucoma (92.8%, 9.1%), and endophthalmitis (0.0%, 0.0%) for 23-G group, 25-G group, respectively (P > 0.05). CONCLUSION: 25-G vitrectomy is as effective for PDR as 23-G vitrectomy.

Abstract
PURPOSE To evaluate the short- and long-term surgical and clinical outcomes in eyes with diabetic tractional retinal detachment (TRD) undergoing 25-G+ pars-plana vitrectomy (PPV). METHODS A total of 238 patients were reviewed for inclusion in this study. A retrospective cohort study of 109 eyes of 73 patients operated on for diabetic TRD were included. All eyes received intraocular tamponade of air, sulfur hexafluoride, octofluropropane or silicone oil. All patients were followed up for a minimum period of one year. RESULTS The mean age of all patients at surgery was 53.9 years ± 9.2, while the mean duration of diabetes was 18.7 ± 10.4 years. The mean length of follow-up was 923 ± 87 days after surgery (range, 432-1792 days). Thirty-two cases (29.3 %) had an associated rhegmatogenous component. Mean BCVA improved from logarithm minimum angle of resolution (logMAR) 1.17 (20/300) to 0.812 (20/130) (p < 0.05). All eyes underwent intraoperative laser photocoagulation. Primary, single-surgery anatomic reattachment was achieved in 99 eyes (91 %). Final anatomic attachment was achieved in 107 eyes (98 %). There was no statistically significant difference in primary or secondary re-attachment rate in terms of type of tamponade agent used. There were five cases of post-operative hypotony (≤5 mmHg) on postoperative day 1, while 11 eyes had IOP ≥ 30 mmHg. There were no cases of endophthalmitis in our cohort. CONCLUSIONS 25G+ PPV provides for safe and effective repair of diabetic TRDs. Patients experienced positive functional and anatomic outcomes, with no significant intraoperative complications and minimal postoperative sequelae.

Abstract
Objective: To study the outcomes of passive removal of silicone oil by 23 Gauge Transconjunctival Sutureless Vitrectomy System. Methods: This prospective, consecutive case series study was conducted at Ophthalmology Department Unit I, Dow University of Health Sciences, Civil Hospital Karachi from January 2011 to December 2014. Only psuedophakic eyes with silicone oil temponade were selected. Main outcome measures were intra ocular pressure, time taken for removal of silicone oil, per operative and post operative complications. Pre and post operative IOP was compared by using two-tailed paired t-test and mean values with standard deviation were computed using difference of 95% confidence interval. Chi square test was applied for correlation of different variables. P-value of less than 0.05 was considered statistically significant. Results: Out of 79 patients who underwent passive ROSO, 38 (48.1%) were males. Mean age of patients was 47.5±7.1 (sd) years. Mean time taken for passive ROSO was 7.31±2.41 (sd) minutes. Pre and post operative intra ocular pressure shows statistically significant (p=0.000) decrease in IOP. Retinal redetachment found in 13 (16.5%) cases during follow up period. Conclusion: Passive removal of silicone oil with 23 G suture less vitrectomy system is safe and effective in terms of less per operative and post operative complications. In this simple technique, there is less tissue trauma and little time consumed so it provides more comfort to patients and surgeons as well.

Abstract
Silicone oils that are easier to inject and remove with smaller-gauge instruments, and in surplus have a reduced propensity for emulsification, offer great potential in vitreoretinal procedures. Safety and efficacy of Siluron2000 silicone oil in treatment of full-thickness macular hole were compared with those of Siluron5000 oil. We also assessed the efficacy of perfluorobutylpentane in removing emulsified oil droplets from the eye using ultrasound imaging. To evaluate safety and efficacy of using Siluron2000 silicone oil in the treatment of full-thickness macular hole by comparing its propensity to emulsify with emulsification of the “gold standard” Siluron5000, and to assess safety and efficacy of F4H5 (perfluorobutylpentane) in removing emulsified oil droplets from the eye.

Abstract
Aim To evaluate the effectiveness and safety of high-speed (5,000 cuts per minute) 23 G transconjunctival sutureless vitrectomy (TSV) in severe diabetic fibrovascular proliferation (DFVP). Patients and methods In this retrospective consecutive case series, patients who underwent 23 G TSV for severe DFVP between October 2011 and March 2014 at our institution were evaluated. 23 G TSV was performed with a high-speed (5,000 cuts per minute) cutter without a chandelier light. Results The mean follow-up period was 8 months (range: 4–23 months). Of the 27 eyes of 27 patients, 14 eyes (52%) underwent concomitant phacoemulsification with posterior chamber intraocular lens implantation, nine eyes (33%) were pseudophakic, and four eyes were phakic (15%). DFVP was removed with ease in all, and visual acuity was improved in 18 (67%) eyes. Iatrogenic retinal tear was observed in four eyes (15%) and treated successfully during surgery. Suture placement to a single sclerotomy was performed in eight eyes (30%). Postoperative intraocular hemorrhage was observed in five eyes (18%). Cataract formation was observed in two of the four phakic eyes. Three (11%) patients had postoperative intraocular pressure rise. Postoperative hypotony (≤6 mmHg) and endophthalmitis were not observed in any eye. Conclusion The segmentation and removal of fibrovascular membranes with high-speed 23 G TSV seems to be a safe and easy method in severe diabetic eye disease.

Abstract
Background The role of pars plana vitrectomy (PPV) for endophthalmitis has evolved over recent decades but the literature is lacking on comparisons between small-gauge and 20-gauge vitrectomy. Objective To evaluate evolving etiological and microbiological trends in patients undergoing vitrectomy for endophthalmitis and to compare culture-positive rates and visual outcomes between small-gauge (23- and 25-gauge) and 20-gauge instrumentation during vitrectomy for endophthalmitis. Methods Ten-year retrospective comparative case series and prospective laboratory in vitro testing. Tertiary care academic referral center. Patients who underwent PPV for endophthalmitis between 2003 and 2013. Vitreous biopsies were obtained in all cases. The effect of vitrectomy gauge (20-, 23-, and 25-gauge) and vitreous cutting rate (1,500 and 5,000 cuts per minute) on the viability of bacterial culture was evaluated in an in vitro prospective laboratory investigation. Main outcome measures Comparison of etiology, microbiology culture-positive rates, and visual outcomes between small-gauge and 20-gauge instrumentation in patients undergoing PPV for infectious endophthalmitis. Results A total of 61 cases of vitrectomy for endophthalmitis were identified over a 10-year period; of these, 34 were treated with small-gauge (23- and 25-gauge) vitrectomy and 27 were treated with 20-gauge vitrectomy. In the small-gauge group, 12 cases (35.3%) yielded culture-positive results versus 20 cases (74.1%) with culture positivity in the 20-gauge cohort (P=0.002). The most common cause of endophthalmitis was cataract surgery and the most frequently identified organism was coagulase-negative Staphylococci in both groups. There was no significant difference in mean postoperative visual acuities between groups (P=0.33). Etiological trends indicate an increase in endophthalmitis due to intravitreal injection in the small-gauge group (n=9) compared to the 20-gauge group (n=3) (P=0.001). In vitro laboratory testing revealed no significant difference in rates of culture growth for different vitrectomy gauge sizes or vitreous cutting speeds. Conclusion and relevance Small-gauge vitrectomy for endophthalmitis yields final visual outcomes comparable to 20-gauge instrumentation. A significant difference in culture-positive rates was observed between small-gauge and 20-gauge instrumentation for vitrectomy in endophthalmitis; however, laboratory testing indicates this is not related to either vitreous gauge size or cutter speed. Intravitreal injections are emerging as a common etiology of vitrectomy for endophthalmitis.

[PMID: 26746595 DOI: 10.1016/j.ophtha.2015.11.001] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2015] [Revised: 10/16/2015] [Accepted: 11/01/2015] [Indexed: 02/06/2023] Open
Abstract
PURPOSE To determine whether vitrectomy surgery rates have changed over the past decade and factors affecting the odds of undergoing this procedure. DESIGN Retrospective, longitudinal cohort study. PARTICIPANTS All enrollees 21 years of age or older between 2001 and 2012 in a United States managed care network. METHODS Claims data from a managed care network were analyzed to identify all enrollees who underwent 1 vitrectomy or more each year from 2001 through 2012. Rates of vitrectomy per 1000 enrollees were computed each year from 2001 through 2012 for the entire group and separately for patients with and without diabetes mellitus. Multivariate logistic regression assessed factors affecting the odds of undergoing vitrectomy surgery. MAIN OUTCOME MEASURES Annual rates of vitrectomy surgery from 2001 through 2012 and odds ratios (ORs) of undergoing a vitrectomy with 95% confidence intervals (CIs). RESULTS Among the 11 161 907 eligible enrollees, 40 892 (0.4%) underwent vitrectomy over the 12-year period. The average age of those undergoing vitrectomy was 57±13 years. Overall vitrectomy rates increased 31% from 2001 to 2012 (from 1.47 to 1.92 per 1000 patients). During this same period, the vitrectomy rate among persons with diabetes mellitus decreased by 43% (from 5.84 to 3.31 per 1000 patients with diabetes). Women had 24% decreased odds of undergoing vitrectomy (adjusted odds ratio [OR], 0.76; 95% confidence interval [CI], 0.72-0.79). The odds of undergoing a vitrectomy were 17% greater for black persons (adjusted OR, 1.17; 95% CI, 1.07-1.27) and 7% higher for persons with diabetes (adjusted OR, 1.07; 95% CI, 1.01-1.14). CONCLUSIONS Overall, we observed an increase in the vitrectomy rates per 1000 enrollees in this large managed care network over the course of the past decade. However, among persons with diabetes mellitus, vitrectomy rates declined substantially over this period. These changes may be explained, in part, by advances in surgical instrumentation and imaging methods to detect retinal diseases changing indications for surgery, improvements in diabetes care, and alternative treatment options for managing retinal conditions. These results may be useful for future planning of manpower needs and highlight the need for aggressive prevention of complications in black persons with diabetes.

Abstract
Purpose To evaluate the outcomes and complications of patients with diabetic tractional retinal detachment (TRD) treated with pars plana vitrectomy (PPV). Patients and methods We retrospectively studied a case series of 24 eyes of 21 patients at a single tertiary, university-affiliated medical center. A review was carried out on patients who underwent PPV for the management of TRD due to proliferative diabetic retinopathy from October 2011 to November 2013. Preoperative and final visual outcomes, intraoperative and postoperative complications, and medical background were evaluated. Results A 23 G instrumentation was used in 23 eyes (95.8%), and a 25 G instrumentation in one (4.2%). Mean postoperative follow-up time was 13.3 months (4–30 months). Visual acuity significantly improved from logarithm of the minimum angle of resolution (LogMAR) 1.48 to LogMAR 1.05 (P<0.05). Visual acuity improved by ≥3 lines in 75% of patients. Intraoperative complications included iatrogenic retinal breaks in seven eyes (22.9%) and vitreal hemorrhage in nine eyes (37.5%). In two eyes, one sclerotomy was enlarged to 20 G (8.3%). Postoperative complications included reoperation in five eyes (20.8%) due to persistent subretinal fluid (n=3), vitreous hemorrhage (n=1), and dislocated intraocular lens (n=1). Thirteen patients (54.2%) had postoperative vitreous hemorrhage that cleared spontaneously, five patients (20.8%) required antiglaucoma medications for increased intraocular pressure, seven patients (29.2%) developed an epiretinal membrane, and two patients (8.3%) developed a macular hole. Conclusion Patients with diabetic TRD can benefit from PPV surgery. Intraoperative and postoperative complications can be attributed to the complexity of this disease.

Abstract
PURPOSE To evaluate the outcomes and complications of 25-gauge (G) pars plana vitrectomy (PPV) for repair of diabetic tractional retinal detachment (TRD). METHODS Retrospective review of consecutive, single-surgeon 25-G PPV cases between July 2007 and July 2014. Seventy eyes from 55 patients were operated on for diabetic TRD; all eyes were tamponaded with sulfur hexafluoride, octofluoropropane, silicone oil, or balanced salt solution. Mean age at surgery was 47.7 years (range 23-76 years), and mean length of follow-up was 713 days (range 90-2368 days; median 671 days). Primary outcomes included best-corrected visual acuity (BCVA), intraocular pressure (IOP), anatomic success, redetachment, and endophthalmitis. RESULTS Preoperatively, 49 eyes (70%) had a concurrent rhegmatogenous component (8 of which also had proliferative vitreoretinopathy (PVR)). Mean BCVA improved from logarithm of the minimal angle of resolution 1.59 (20/800, SD 0.88) to 0.68 postoperatively (20/100, 0.77), P-value<0.001. Mean IOP increased from 15.9 to 20 mm Hg 1 day after surgery. Elevated postoperative IOP (≥ 22 mm Hg) occurred in 25 eyes, and low IOP (≤ 5 mm Hg) occurred in 2 eyes. Primary reattachment was achieved in 63 eyes (90%), and final anatomical success occurred in 69 eyes (99%). There were no cases of endophthalmitis. CONCLUSIONS Twenty-five-G PPV repair was safe and effective in the repair of diabetic TRD, including eyes with a combined rhegmatogenous detachment or PVR. Gas, silicone oil, and balanced salt solution tamponading agents all proved to be efficacious in this surgical population.

Abstract
Surgery for late complications of proliferative diabetic retinopathy remains the cornerstone of management even in patients who have received optimal laser photocoagulation and medical therapy. With improvisation in the surgical techniques and development of micro-incision surgical techniques for vitrectomy, the indications for surgical intervention are expanding to include diabetic macular edema with a greater number of patients undergoing early intervention. This review describes the current indications, surgical techniques, adjunctive anti-vascular endothelial growth factor therapy, surgical outcomes, and postoperative complications of pars plana vitrectomy for proliferative diabetic retinopathy and macular edema.

Abstract
BACKGROUND Endophthalmitis is a rare but severe complication of vitrectomy. CLINICAL RELEVANCE Post-surgical endophthalmitis is suspected to be more frequent after microincisional (23- and 25-gauge) compared with standard (20-gauge) vitrectomy. METHODS We conducted a systematic review of studies that compared microincisional and standard vitrectomy by searching MEDLINE and EMBASE up to November 2012. We used the Bayesian meta-analysis method to compute the odds ratio (OR) of endophthalmitis. We conducted subgroup analyses to compare the effect of different incision types and use of perioperative antibiotics. RESULTS We identified 3 small randomized and 18 nonrandomized studies that reported 68 cases of endophthalmitis in 148 643 participants. The overall OR of endophthalmitis for microincisional versus standard vitrectomy was 2.3 (95% credible interval [CrI], 0.8-5.8). We found an increased risk of endophthalmitis using a microincisional straight approach compared with standard vitrectomy (OR, 15.1; 95% CrI, 2.01-179), but not for a beveled approach (OR, 0.82; 95% CrI, 0.23-2.28). The OR of studies that reported on mixed microincision was between these 2 values (OR, 4.4; 95% CrI, 1.32-14.3). We estimated that the overall rate of endophthalmitis with 20-gauge vitrectomy was 3 cases in 10 000 procedures, and the probability that a beveled microincision increases the rate of endophthalmitis to more than 6 or 9 events was small (no more than 5% or 1%, respectively). CONCLUSIONS We did not find an increased risk of endophthalmitis for microincisional vitrectomy compared with standard vitrectomy. The beveled approach seems to be safer than a straight approach, supporting the current recommendation of its adoption in microincisional vitrectomy. However, these findings must be interpreted cautiously because of the small number of endophthalmitis events reported from included studies.

Abstract
PURPOSE To report the efficacy of 23-gauge (G) pars plana vitrectomy with silicone oil injection in rhegmatogenous retinal detachment. METHODS Retrospective chart review of consecutive patients with retinal detachment who underwent pars plana vitrectomy by one of two surgeons using distinct and consistent methods. All patients undergoing 23-G pars plana vitrectomy did not have scleral buckling, whereas all patients undergoing surgery by 20-G pars plana vitrectomy had additional 240-band encircling scleral buckle. All patients received silicone oil tamponade. Patients with proliferative vitreoretinopathy Grade D, previous retinal detachment surgery, and penetrating eye injury were excluded. The main outcome measure was the final anatomical reattachment rate. The secondary outcome measures were the improvement in visual acuity and recurrence rate of retinal detachment after primary surgery. RESULTS Eighteen patients in the 23-G group and 21 patients in the 20-G group were analyzed. The mean age of the patients was 48.05 ± 10.37 years and 42.57 ± 17.84 years in the 23-G and 20-G groups, respectively. The mean follow-up duration was 5.9 months (range, 2-12 months) and 6.2 months (range, 4-9 months) in the 23-G and 20-G groups, respectively. The primary reattachment rate was 83.3% (95% confidence interval, 66.11%-100%) in the 23-G group and 86.8% (95% confidence interval, 67.81%-100%); P = 1.00) in 20-G group. The mean preoperative logarithm of the minimum angle of resolution visual acuity was 1.30 ± 0.57 (Snellen equivalent 20/400) in the 23-G group and 1.27 ± 0.70 (Snellen equivalent 20/400) in the 20-G group (P = 0.80). The mean logarithm of the minimum angle of resolution visual acuity at 1 month after the surgery was 0.66 ± 0.25 (Snellen equivalent 20/100) in the 23-G group and 0.77 ± 0.50 (Snellen equivalent 20/120; P = 0.46) in the 20-G group. The visual acuity at the last visit was 0.80 ± 0.52 (20/125) versus 0.65 ± 0.44 (20/100) in the 23-G and 20-G, respectively (P = 0.32). CONCLUSION Silicone oil injection with 23-G system is possible and is associated with favorable anatomical success in cases of rhegmatogenous retinal detachment.

Abstract
PURPOSE To determine if a difference in intraocular pressure (IOP) exists after small-gauge pars plana vitrectomy randomized to fluid versus 80% sterile air fill. METHODS Ninety-two eyes undergoing 23-gauge and 25-gauge transconjunctival pars plana vitrectomy were randomized to fluid versus air fill, and IOP was measured at 5 different time points. RESULTS There is no difference in the mean IOP for eyes undergoing small-gauge pars plana vitrectomy randomized to fluid versus air fill after vitrectomy. Using 23-gauge instrumentation, the mean immediate and 2-hour postoperative IOPs were statistically lower than the mean preoperative IOP. The mean Postoperative Day 1 and Week 1 IOPs were statistically higher than the mean immediate postoperative IOP. Using 25-gauge instrumentation, the mean IOP was not statistically different at any time points in the 2 groups. When comparing 23-gauge with 25-gauge instrumentation, the immediate postoperative IOP was statistically lower and the rate of suture closure for sclerotomies was higher for 23-gauge vitrectomy. CONCLUSION When performing 23-gauge or 25-gauge pars plana vitrectomy, there was no difference in mean IOP for fluid- versus air-filled eyes. However, the mean IOP in the immediate postoperative period was statistically lower, and there was a higher rate of suture closure for 23-gauge compared with 25-gauge instrumentation.

Abstract
PURPOSE To address the incidence, clinical course, and risk factors for postoperative vitreous hemorrhage (PVH) after a 25-gauge transconjunctival sutureless vitrectomy for proliferative diabetic retinopathy. METHODS A consecutive series of eyes underwent 25-gauge transconjunctival sutureless vitrectomies for proliferative diabetic retinopathy. The best-corrected visual acuities and intraocular pressures were measured, and the complications were prospectively evaluated 1 day, 1 week, 1 month, and 3 months postoperatively, then as needed. RESULTS The mean postoperative follow-up was 11.0 ± 6.3 months (range, 6-28 months). Of 93 eyes, 42 had PVH on Day 1 (immediate PVH) but the presence and degree of PVH did not affect visual recovery and only 4 eyes did not clear for 1 month (persistent PVH). Recurrent PVH occurred in 11 eyes. Eight eyes had hypotony on Day 1, and patients who experienced postoperative hypotony had an 11.20-fold increased risk of immediate PVH > Grade 2. In the cases that needed intravitreal tamponade, the risk of recurrent PVH was 3.03-fold higher. CONCLUSION After 25-gauge transconjunctival sutureless vitrectomies for proliferative diabetic retinopathy, postoperative hypotony and the need for tamponade increased the rates of immediate and recurrent PVH, respectively. Immediate PVH occurred in 45.2% of the patients but did not affect early visual recovery. A 25-gauge transconjunctival sutureless vitrectomy resulted in a favorable incidence of recurrent PVH (11.8%) during the first 6 months.

Abstract
Small gauge vitrectomy utilizing 23- and 25-gauge instrumentation has definite advantages, but also limitations, due to the physics of smaller instruments and sutureless surgery. Higher infusion and aspiration pressures are needed to remove the vitreous using 23- and 25-gauge probes. The advantages include decreased surgical times, less tissue manipulation, reduced inflammation and pain postoperatively with more rapid visual recovery. A disadvantage is greater instrument flexion than 20-gauge probes, making small gauge vitrectomy more appropriate for indications such as vitreous opacities, epiretinal membranes, macular holes, and simple retinal detachments. There are also some increased complications related to small gauge vitrectomy, including dislocation of cannulas intraoperatively, early postoperative hypotony, choroidal detachment, and possibly an increased risk of infectious endophthalmitis.

Abstract
PURPOSE The purpose of this study was to report the outcomes and complications of 25-gauge pars plana vitrectomy for the management of retained lens fragments after complicated cataract surgery. METHODS This is a retrospective consecutive case series of 17 patients who presented with retained lens fragments, ranging from mostly cortex to the entire lens, which were managed using only 25-gauge instrumentation. RESULTS Eight men and 9 women (mean age, 73.1 years) were followed for a mean of 4.5 months after 25-gauge vitrectomy for removal of retained lens fragments. Mean preoperative visual acuity was 20/427 and mean final postoperative visual acuity was 20/62. Mean surgical operating time was 48.5 minutes. Mean preoperative intraocular pressure was 24.5 mmHg and mean 1-day postoperative intraocular pressure was 17.9 mmHg. No cases required the use of a phacofragmatome, no sutures were required to close the sclerotomies, and there were no cases of postoperative hypotony. Cystoid macular edema and glaucoma developed postoperatively in 29.4% and 5.9% of eyes, respectively. There were no cases of postoperative retinal detachment or endophthalmitis. CONCLUSION A 25-gauge vitrectomy technique, without the use of a phacofragmatome, may be a suitable alternative to 20-gauge vitreous surgery using a phacofragmatome in the management of retained lens fragments after complicated cataract surgery. Clinical outcomes and complication rates are comparable to those found in the literature for 20-gauge surgery.
