Abstract
PURPOSE This study presents a novel sutureless closure approach for sclerotomies following pars plana vitrectomy (PPV) and assesses its efficacy and safety. METHODS A total of 142 eyes were included in the study. PPV procedures were performed using 23-gauge (23 G) or 25-gauge (25 G) systems. Preoperative characteristics, intraoperative findings, and postoperative outcomes were documented. RESULTS The cohort included 80 males and 62 females (mean age: 60.4 ± 12 years), primarily undergoing surgery for retinal detachment (59%). Among the patients, 87% underwent 25 G PPV (35% three-port, 52% four-port), while 13% underwent 23 G PPV (12% three-port, 1% four-port). Gas tamponade was administered in all cases, with perfluoropropane used in 45.7% of instances, sulfur hexafluoride in 29.5%, and air in 24.6%. Spontaneous closure was observed in 9.4% (47 of 501) of sclerotomies, autologous-fibrin induction approach successfully closed 75.8% (380 of 501) of the sclerotomies (83.7% of leaking sclerotomies) and 14.7% (74 of 501) of sclerotomies needed sutures. Visual acuity improved postoperatively, and first-day hypotony rate was 6.3%. Importantly, no serious complications such as choroidal detachment or endophthalmitis were observed during the postoperative period. CONCLUSION The autologous-fibrin induction offers a simple, cost-efficient, and reliable approach for sutureless sclerotomy closure in PPV, with promising outcomes.

Conjunctival Pigmentation Following Pars Plana Vitrectomy (PPV) for Rhegmatogenous Retinal Detachment: Risk Factors and Outcomes. Cureus 2023; 15:e36987. [PMID: 37012958 PMCID: PMC10066063 DOI: 10.7759/cureus.36987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/30/2023] [Indexed: 04/04/2023] Open
Abstract
Purpose: To investigate the incidence and the risk factors for conjunctival pigmentation at the sclerotomy sites following valved and non-valved cannula pars plana vitrectomy (PPV) performed by different surgical techniques. Methods: This is a prospective observational study which included 70 eyes of 70 patients who underwent PPV for rhegmatogenous retinal detachment with follow-up visits at 1, 3, 6, 12, and 24 months. Twenty-eight eyes were operated using 25G non-valved cannulas (Group A), 22 eyes using 25G non-valved cannulas (Group B), and 20 eyes using 25G valved cannulas (Group C). The evaluated clinical parameters include the surgical technique, the patients' age, the number of retinal tears, the tamponade agent, the presence of residual sub-retinal fluid (SRF), and the duration of postoperative posturing. Results: Group A was associated with significant conjunctival pigmentation at up to 6 months after PPV. Sulfur hexafluoride (SF6) gas tamponade was associated with less conjunctival pigmentation at 3 months follow-up visit [odds ratio, OR 0.09 (95% confidence interval, CI 0.01; 0.67)], whereas the presence of residual SRF was a significant risk factor for postoperative pigmentation at 1-year follow-up visit [OR 5.89 (95% CI 1.84; 23.12)]. The area of measured pigmentation was also positively correlated to the number of retinal tears at all follow-up visits over 2 years. Six patients presented with conjunctival pigmentation at 2 years follow-up visit. Conclusion: New vitrectomy techniques with valved cannulas prevent the postoperative appearance of conjunctival pigmentation. The number of retinal tears, the presence of SRF, and the use of long-standing tamponade agents were the most significant predisposing factors. The post-vitrectomy conjunctival pigmentation gradually reduces over time.

Effect of Changes in Surgical Strategies for the Treatment of Primary Rhegmatogenous Retinal Detachment on Functional and Anatomical Outcomes: A Retrospective Analysis of 812 Cases from the Years 2004 to 2012. J Clin Med 2023; 12:jcm12062278. [PMID: 36983279 PMCID: PMC10057392 DOI: 10.3390/jcm12062278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 03/09/2023] [Accepted: 03/13/2023] [Indexed: 03/17/2023] Open
Abstract
Background: At the Department of Ophthalmology and Optometry at the MUV surgical method (scleral buckling, vitrectomy, combined vitrectomy/scleral buckling) and timing (daytime, nighttime) for the treatment of primary rhegmatogenous retinal detachment (RRD) changed continuously in the years 2004 to 2012. This study aims to evaluate changes in surgical strategies over time including their impact on functional and anatomical outcomes. Methods: Retrospective evaluation of patients operated on primary RRD between the years 2004 and 2012. Baseline demographic data, month 3 best-corrected visual acuity (BCVA), surgical method, single success surgery, surgical timing, and intraoperative complications were analyzed. Results: Overall, 812 eyes of 812 patients with a mean (±SD) age of 58.1 ± 13.3 years were included. A total of 413 (51%) patients presented with macula-on and 359 (44%) with macula-off RRD. Month 3 BCVA increased over time, both in macula-on or macula-off groups (p < 0.001). The rate of complete retinal reattachment 3 months postoperatively increased significantly from 65% in 2004 to 83% in 2012 in both groups. Scleral buckling surgeries decreased continuously from 95% to 16% with an appropriate increase in vitrectomies as well as a decrease in surgeries during nighttime (68% in 2004, 6% in 2012) with equal or better visual and functional outcomes. Conclusion: Our data showed that improving functional and single-success surgery outcomes in patients operated on for primary RRD. In the years 2004 to 2012, surgical techniques shifted from scleral buckling to primary vitrectomy and were increasingly scheduled during the daytime.

Abstract
Rhegmatogenous retinal detachment (RRD) is the most common retinological emergency that can cause blindness without surgical treatment. RRD occurs when liquefied vitreous accumulates between the neurosensory retina and the retinal pigment epithelium via retinal breaks, which are caused by the separation of the vitreous from the retina with aging. Currently, the main treatment option is pars plana vitrectomy, which involves surgical removal of the vitreous and laser photocoagulation around retinal breaks to generate firm chorioretinal adhesion, as well as subsequent filling of the vitreous cavity with long-lasting substitutes (expansile gas or silocone oil) to prevent the connection between the subretinal space and the vitreous cavity via the breaks before the chorioretinal adhesion firm enough. However, the postoperative face-down position and the not very satisfactory first retinal reattachment rate place a heavy burden on patients. With the development of technology and materials engineering, researchers have developed biomaterials that can be used as a retinal patch to seal retinal breaks and prevent the connection of subretinal space and vitreous cavity via breaks, thus replacing the long-lasting vitreous substitutes and eliminating the postoperative face-down position. Preclinical studies have demonstrated that biomaterial sealants have enough biocompatibility and efficacy in the in vitro and in vivo experiments. Some sealants have been used in clinical trials on a small scale, and the results indicate promising application prospects of the biomaterial sealants as retinal patches in the repair of RRD. Herein, we review the recent advances in biomaterials as retinal patches for the repair of RRD, focusing on the biomaterial categories, methods, and procedures for sealing retinal breaks, as well as their biocompatibility and efficacy, current limitations, and development perspectives.

Abstract
(1) Background: The aim was to describe the rate and outcomes of cystoid macular edema (CME) after pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD) and to identify risk factors and imaging characteristics. (2) Methods: A retrospective consecutive case study was conducted over a 5-year period among adult patients who underwent PPV for primary RRD repair. The main outcome measure was the rate of CME at 12 months following PPV. (3) Results: Overall, 493 eyes were included. The CME rate was 28% (93 patients) at 12 months. In multivariate analysis, eyes with worse presenting visual acuity (VA) (odds ratio [OR], 1.55; 95% CI, 1.07–2.25; p = 0.02) and grade C proliferative vitreoretinopathy (PVR) (OR, 2.88; 95% CI, 1.04–8.16; p = 0.04) were more at risk of developing CME 1 year after PPV. Endolaser retinopexy was associated with a greater risk of CME than cryotherapy retinopexy (OR, 3.06; 95% CI, 1.33–7.84; p = 0.01). Eyes undergoing cataract surgery within 6 months of the initial RRD repair were more likely to develop CME at 12 months (OR, 1.96; 95% CI, 1.06–3.63; p = 0.03). (4) Conclusions: CME is a common complication after PPV for primary RRD repair. Eyes with worse presenting VA, severe PVR at initial presentation, endolaser retinopexy, and cataract surgery within 6 months of initial RRD repair were risk factors for postoperative CME at 12 months.

Biocompatibility and Efficacy of a Linearly Cross-Linked Sodium Hyaluronic Acid Hydrogel as a Retinal Patch in Rhegmatogenous Retinal Detachment Repairment. Front Bioeng Biotechnol 2022; 10:914675. [PMID: 35860332 PMCID: PMC9289194 DOI: 10.3389/fbioe.2022.914675] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 05/25/2022] [Indexed: 11/13/2022] Open
Abstract
To prevent the migration of retinal pigment epithelium (RPE) cells into the vitreous cavity through retinal breaks after the pars plana vitrectomy for the repair of rhegmatogenous retinal detachment (RRD), sealing retinal breaks with an appropriate material appears to be a logical approach. According to a review of ocular experiments or clinical trials, the procedure for covering retinal breaks with adhesives is complex. A commercially available cross-linked sodium hyaluronic acid (HA) hydrogel (Healaflow®) with the injectable property was demonstrated to be a perfect retinal patch in RRD clinical trials by our team. Based on the properties of Healaflow®, a linearly cross-linked sodium HA hydrogel (HA-engineered hydrogel) (Qisheng Biological Preparation Co. Ltd. Shanghai, China) with the injectable property was designed, whose cross-linker and cross-linking method was improved. The purpose of this study is to report the characteristics of an HA-engineered hydrogel using Healaflow® as a reference, and the biocompatibility and efficacy of the HA-engineered hydrogel as a retinal patch in the rabbit RRD model. The HA-engineered hydrogel exhibited similar dynamic viscosity and cohesiveness and G′ compared with Healaflow®. The G′ of the HA-engineered hydrogel varied from 80 to 160 Pa at 2% strain under 25°C, and remained constantly higher than G″ over the range of frequency from 0.1 to 10 Hz. In the animal experiment, clinical examinations, electroretinograms, and histology suggested no adverse effects of the HA-engineered hydrogel on retinal function and morphology, confirming its favorable biocompatibility. Simultaneously, our results demonstrated the efficacy of the HA-engineered hydrogel as a retinal patch in the RRD model of rabbit eyes, which can aid in the complete reattachment of the retina without the need for expansile gas or silicone oil endotamponade. The HA-engineered hydrogel could play the role of an ophthalmologic sealant due to its high viscosity and cohesiveness. This pilot study of a small series of RRD models with a short-term follow-up provides preliminary evidence to support the favorable biocompatibility and efficacy of the HA-engineered hydrogel as a promising retinal patch for sealing retinal breaks in retinal detachment repair. More cases and longer follow-up studies are needed to assess its safety and long-term effects.

Abstract
PURPOSE To describe and evaluate the efficacy of a novel technique, scleral needling (SN), for securing 23- and 25-gauge leaking sclerotomies in microincision vitrectomy surgery. METHODS A retrospective comparative review of consecutive cases of 23- and 25-gauge pars plana vitrectomy performed by a single vitreoretinal surgeon before the introduction of the SN technique (pre-SN; November 2016 to January 2017) and after the introduction of the SN technique (post-SN; November 2017 to January 2018) was conducted. The SN technique was implemented as an alternative to suturing, using a 30-gauge needle inserted perpendicularly through the full thickness of the sclera adjacent to the scleral opening, with the needle then immediately removed and sclerotomy closure confirmed. RESULTS A total of 203 eyes, 105 from pre-SN and 98 from post-SN, were included in the study. The number of eyes requiring suture closure was significantly reduced from 39% in the pre-SN group to 2% in the post-SN group (P < 0.001). The mean postoperative intraocular pressure and incidence of hypotony on Days 1 to 2, Days 3 to 20, and Days 21 to 50 was not significantly different between the pre-SN and post-SN groups. No major complications associated with the SN technique were noted during the study period. CONCLUSION The SN technique is a safe and simple method for effectively securing leaking sclerotomies in microincision vitrectomy surgery.

Efficacy and Safety of Vitrectomy without Using Perfluorocarbon Liquids and Drainage Retinotomy Associated with Postoperative Positioning Based on Residual Subretinal Fluid for Rhegmatogenous Retinal Detachment. J Ophthalmol 2021; 2021:5588479. [PMID: 33996150 PMCID: PMC8081592 DOI: 10.1155/2021/5588479] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 03/22/2021] [Accepted: 04/07/2021] [Indexed: 11/20/2022] Open
Abstract
Medical records of 75 eyes from 75 consecutive patients with uncomplicated rhegmatogenous retinal detachment (RRD) who underwent pars plana vitrectomy (PPV) were analyzed. Inclusion criteria were patients with RRD who underwent primary 23- or 25-gauge PPV with air, gas, or SiO tamponade and performed by a single surgeon, no use of perfluorocarbon liquids (PFCL) and drainage retinotomy, and follow-up ≥ six months. Exclusion criteria were patients who underwent previous vitreoretinal surgery, proliferative vitreoretinopathy (PVR) more than grade B, giant tears, and encircling band associated with PPV. The main endpoint was the anatomical retinal reattachment rate after a single surgical procedure. Secondary endpoints were best-corrected visual acuity (BCVA), postoperative retinal displacement, and intraoperative and/or postoperative complications. Primary anatomical success was achieved in 97.3% of cases using this modified surgical procedure. Retinal slippage occurred only in 28.2% of patients and it was not observed in all cases of macula-on RRD. The mean logMAR of the BCVA significantly improved in 92% of patients and no intraoperative complications were observed. The results suggest that complete subretinal liquid drainage is not mandatory for all RRD cases treated with PPV and that using PFCL and performing a drainage retinotomy are not essential in eyes with primary RRD and PVR less than grade B. Postoperative positioning after PPV for uncomplicated RRD based on the presence or absence of residual subretinal fluid at the end of surgery could limit the occurrence of postoperative retinal displacement, while promoting patient compliance.

Abstract
PURPOSE To assess and compare safety and effectiveness between 23-gauge and 25-gauge vitrectomy systems for the treatment of common vitreoretinal diseases in non-vitrectomized eyes. METHODS Retrospective evaluation of patients who underwent pars plana vitrectomy from April 2018 to December 2019 at the Department of Ophthalmology and Optometry at the Medical University of Vienna (MUV) for the following indications: macular epiretinal membrane, macular hole, macular lamellar hole, vitreous hemorrhage, vitreous opacities, vitreomacular traction syndrome and macular edema. RESULTS 201 eyes of 195 patients that underwent 23-gauge (n = 105 eyes) or 25-gauge (n = 96 eyes) vitrectomy were included in this study. The mean best-corrected visual acuity (BCVA) improved at 1-3 months postoperatively and beyond 3 months in both gauge groups. Risk of any complication within 1 month postoperatively was lower in the 25-gauge group, but the difference was statistically not significant (HR [95% CI]: 0.95 [0.53; 1.70], p = 0.85). Intraocular pressure less than 5 mmHg was observed in 2 eyes (2%) in the 23-gauge group at the first postoperative day. Intraocular pressure elevation over 25 mmHg occurred in 5 eyes (2 eyes, 2%, in 23-gauge and 3 eyes, 3%, in 25-gauge group) at postoperative day 1, between 7 and 28 days in 5 cases (2 eyes, 2%, in 23-gauge and 3 eyes, 3%, in 25-gauge group), and in 2 eyes (2%) of the 23-gauge group at postoperative day 145 and 61, respectively. Retinal detachment occurred in 1 eye (1%) in the 23-gauge and in 3 eyes (3%) in the 25-gauge group. We did not observe any cases of endophthalmitis. CONCLUSION Results in terms of safety, surgical success and visual outcomes for the treatment of common vitreoretinal surgery indications seem to be comparable between 23-gauge and 25-gauge vitrectomy systems, indicating that the two gauge systems can be used equally in the clinical routine.

Abstract
BACKGROUND To compare outcomes and complications of pars plana vitrectomy (PPV) using a three-dimensional heads-up visualisation system (digitally assisted vitreoretinal system, DAVS) versus conventional analog microscope (CAM) in primary rhegmatogenous retinal detachment (RRD). METHODS This prospective interventional institutional study evaluated 60 eyes of 60 subjects with primary RRD undergoing PPV between September 2017 and February 2018. Subjects were randomly put into DAVS and CAM group and pre-operative ocular characteristics and final outcomes recorded at each visit. All subjects were followed up for a duration of 6 months. Main outcome measures recorded were post-operative retinal status, visual acuity (VA), intraocular pressure (IOP) and surgical complications. RESULTS Overall final retinal attachment at 6 months was 91.7% (90% in DAVS eyes and 93.3% in CAM eyes; p = 0.999). Final VA improved significantly from baseline in both groups (p < 0.001). Overall, VA improved to > = 20/40 in 18.3% eyes (6 DAVS, 5 CAM). Median duration of silicone oil endotamponade was 3.5 months (3.5 months in DAVS, 3 months in CAM). Redetachment rate in the series was 25% (20% in DAVS, 30% in CAM). Post-operative proliferative vitreoretinopathy grade C and more was present in 15% of eyes (10% in DAVS, 20% in CAM). Average duration of surgery was 37 ± 6.2 min in DAVS group and 39.8 ± 6.6 min in CAM group (p = 0.09). All steps of vitrectomy could be performed with relative ease and comfort with the DAVS platform. CONCLUSION Anatomical and functional outcomes of RRD were favourable with DAVS and comparable to that with conventional microscope surgery.

[PMID: 33406140 PMCID: PMC7787454 DOI: 10.1371/journal.pone.0244614] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Accepted: 12/11/2020] [Indexed: 01/06/2023] Open
Abstract
Purpose To assess the preoperative characteristics and surgical outcomes of using micro-incision vitrectomy surgery (MIVS) to treat RRD with posterior vitreous detachment (PVD) in an older and a younger patient group. Methods This retrospective cohort study included 407 eyes from 397 patients with primary RRD with PVD who were consecutively treated in our hospital from February 2016 to February 2020. PVD was diagnosed clinically by the presence of a Weiss ring, or was diagnosed morphologically via optical coherence tomography and subsequently confirmed during surgery. The main outcome measures were preoperative RRD characteristics, best-corrected visual acuity (BCVA), and postoperative complications. Results Data were analysed from 55 eyes in the elderly group (age 70 and older), and 352 eyes in the young group (age 69 and younger). There was no significant inter-group difference in the initial reattachment rate. Preoperative characteristics indicated that elderly patients had a significantly lower rate of phakic eyes, shorter mean axial length, lower lattice incidence, and longer time spans from onset to surgery. There were no significant between-group differences in the incidence of the following complications: fibrin formation, intraocular pressure elevation, epi-retinal membrane on the macula, intraocular lens optic capture, proliferative vitreoretinopathy, and vitreous haemorrhage. While the elderly patients had significant postoperative improvements in BCVA, these improvements were significantly lower than those of the younger patients. Conclusions This study highlighted the characteristics and surgical outcomes of MIVS in elderly patients with RRD. Although the time from onset to surgery was longer, MIVS still can be performed safely to improve older patients’ postoperative BCVA.

The comparison of the surgical outcome of 27-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment between air and SF6 gas tamponade. Eye (Lond) 2019; 34:299-306. [PMID: 31857712 DOI: 10.1038/s41433-019-0726-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 08/08/2019] [Accepted: 09/08/2019] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVES To compare the surgical results between air and 20% sulfur hexafluoride (SF6) tamponade in 27-gauge pars plana vitrectomy (27GPPV) for rhegmatogenous retinal detachment (RRD). METHODS A retrospective, observational, and consecutive study. All patients underwent 27GPPV for RRD were divided into two groups. Group A comprised patients who underwent 20% SF6 gas tamponade. Group B comprised patients who underwent air tamponade. The anatomical success rate, visual outcome, and the type and frequency of complications were investigated and compared between the groups. All patients were followed-up for 12 months after surgery. RESULTS Seventy eyes were enrolled (Group A: 35 eyes, Group B: 35 eyes). Seventeen eyes in Group A and 13 eyes in Group B had RRD with superior retinal breaks, while 14 eyes in Group A and 19 eyes in Group B had RRD with inferior retinal breaks. There was no statistically difference in preoperative demographic date between the groups. The initial and final anatomical success rates were 97.1% and 100% in Group A and 94.3% and 100% in Group B, respectively. The success rates between the groups were not statistically different (p = 1). The best corrected visual acuity (BCVA) (logMAR) at 12 months after surgery was -0.02 ± 0.14 in Group A and -0.03 ± 0.27 in Group B. The BCVA between the groups was not statistically different (p = 0.27). CONCLUSIONS The surgical results of air tamponade were not inferior to 20% SF6 tamponade in 27GPPV for RRD irrespective of retinal break locations in the present cohort.

Multicenter survey of sutureless 27-gauge vitrectomy for primary rhegmatogenous retinal detachment: a consecutive series of 410 cases. Graefes Arch Clin Exp Ophthalmol 2019; 257:2591-2600. [PMID: 31478083 DOI: 10.1007/s00417-019-04448-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 08/13/2019] [Accepted: 08/21/2019] [Indexed: 11/29/2022] Open
Abstract
PURPOSE To evaluate the surgical outcomes of the 27-gauge (G) vitrectomy system for the treatment of primary rhegmatogenous retinal detachment (RRD). METHODS This retrospective consecutive series multicenter study involved a total of 410 eyes of 406 patients who underwent 3-port transconjunctival 27G pars plana vitrectomy (PPV) for RRD between November 2014 and December 2016 and who were followed for a minimum of 3 months postoperative. The main outcome measure was primary reattachment, with the secondary outcome measures being final reattachment, improvement of visual acuity (VA), intraocular pressure (IOP), intraoperative and postoperative complications, and surgery time. RESULTS Of the 410 treated eyes, primary reattachment was achieved in 392 (95.6%) and final reattachment was achieved in 410 (100%). In 226 eyes (55.1%) with macula-on RRD, the mean logarithm of the minimum angle of resolution (logMAR) VA improved from 0.16 ± 0.51 pre-surgery to 0.02 ± 0.14 post-surgery (P = 0.11). In 184 eyes (44.9%) with macula-off RRD, logMAR VA improved from 1.06 ± 0.77 pre-surgery to 0.26 ± 0.35 post-surgery (P < 0.001). Following surgery, the mean IOP was highest at 1 day (15.7 ± 7.0 mmHg) postoperative. In all eyes, surgery was concluded without the use of sutures or the need of conversion to a larger-gauge instrument. Although hypotony was observed in 14 (3.4%) of the 410 treated eyes at 1 day postoperative, it spontaneously resolved within 1 week without additional surgical intervention. No postoperative complications such as infectious endophthalmitis were observed throughout the follow-up period. CONCLUSION Our findings show that 27G PPV is both safe and effective for the treatment of primary RRD.

Abstract
PURPOSE To determine the long-term outcome of patients operated with pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD) and to identify potential predictors for poor visual outcome. METHODS Prospective, observational 30-month study of patients operated for primary RRD with PPV. Examinations were performed preoperatively and after months 2, 6, and 30. RESULTS Eighty-four patients (84 eyes) were included and 73 (86.9%) participated at month 30. The macula was attached in 30 (35.7%) patients at primary operation. The majority of patients (n = 59, 80.8%) achieved a good final best corrected visual acuity (BCVA ≤0.3 logMAR, ≥0.5 Snellen) with a better outcome in patients with the macula attached than detached (0.02 vs. 0.17 logMAR, p = 0.007). Variables associated with poor visual outcome were baseline BCVA >0.3 logMAR (p = 0.03), female gender (p = 0.02), silicone oil (p = 0.03), and larger areas of retinal detachment (p = 0.01). In multivariable regression analysis, female gender (OR = 8.5 [95% CI 1.8-39.8]) was the strongest risk factor for poor visual outcome. CONCLUSION The majority of patients operated for primary RRD achieved a reasonable long-term visual outcome. Notably, female gender was associated with poor visual outcome, indicating a need for closer follow-up.

Abstract
PURPOSE To examine the effect of low-dose, oral isotretinoin in lowering the risk of proliferative vitreoretinopathy (PVR) following rhegmatogenous retinal detachment (RRD) repair. METHODS Prospective, open label, dual-cohort study with pathology-matched historical controls. The prospective experimental arms included two cohorts, composed of 51 eyes with recurrent PVR-related RRD and 58 eyes with primary RRD associated with high-risk features for developing PVR. Eyes in the experimental arms received 20 mg of isotretinoin by mouth once daily for 12 weeks starting the day after surgical repair. The primary outcome measure was single surgery anatomical success rate at 3 months following the study surgery. RESULTS The single surgery anatomic success rate was 78.4% versus 70.0% (p=0.358) in eyes with recurrent PVR-related retinal detachment exposed to isotretinoin versus historical controls, respectively. In eyes with RRD at high risk for developing PVR, the single surgery success rate was 84.5% versus 61.1% (p=0.005) for eyes exposed to isotretinoin versus historical controls, respectively. For eyes enrolled in the experimental arms, the most common isotretinoin-related side effects were dry skin/mucus membranes in 106 patients (97.2%), abnormal sleep/dreams in 4 patients (3.7%) and fatigue in 3 patients (2.8%). CONCLUSION The management and prevention of PVR is challenging and complex. At the dose and duration given in this study, oral istotretinoin may reduce the risk of PVR-associated recurrent retinal detachment in eyes with primary RRD at high risk of developing PVR.

Abstract
Purpose To compare the anatomic and functional outcomes of pars plana vitrectomy (PPV) for treating rhegmatogenous retinal detachments (RRDs) between two groups with and without postoperative prone positioning. Methods This retrospective cohort study included 142 eyes of 142 patients with a primary RRD. All patients underwent PPV with 20% sulfur hexafluoride gas tamponade and were divided into two groups: the groups that did and did not maintain a prone position postoperatively. All patients were followed for more than 3 months. The main outcome measures were the best-corrected visual acuity (BCVA), retinal reattachment rate, and postoperative complications. Results Sixty-five eyes were included in the prone position group and 77 eyes in the group without prone positioning; the respective initial reattachment rates were 83.1% and 96.1%, a difference that reach significance (p = 0.011). In the eyes with inferior breaks, the initial reattachment rate was 94.7% (18 eyes) without prone positioning, which was significantly (p = 0.036) better than the 60% (6 eyes) initial reattachment rate in the group with prone positioning. In the eyes without inferior breaks, there was no significant difference in the initial reattachment rates between the two groups. The BCVAs at the 3-month postoperative visit did not differ significantly between the two groups. An epiretinal membrane (ERM) was observed postoperatively in 10 (13.0%) eyes in the group without prone positioning; no ERMs were seen postoperatively in eyes in which the internal limiting membrane (ILM) was peeled during PPV. Conclusions PPV without postoperative prone positioning is associated with a higher reattachment rate in eyes with a RRD, especially those with inferior retinal breaks. PPV with postoperative supine and lateral positioning might be beneficial to manage RRDs associated with inferior retinal breaks if ILM peeling is performed intraoperatively.

Abstract
Purpose To investigate outcomes of vitrectomy for rhegmatogenous retinal detachment (RRD) using air exclusively as the gas tamponade. Methods This retrospective, interventional, consecutive case series involved reviewing medical records of patients that underwent vitrectomy and gas tamponade for RRD between January 2013 and December 2015. Patients whose eyes were treated exclusively with air tamponade since July 2014 were assigned to the air group, while those treated with heterogeneous gas agents before June 2014 were assigned to the control group. The primary outcome was the primary reattachment rate. Best-corrected visual acuity (BCVA) and duration to detect redetachments were assigned as the secondary outcomes. Results The air group and the control group included 71 and 72 eyes, respectively. The primary reattachment rate was 94.4% in the air group and there was no significant difference with 94.4% in the control group (p = 0.951). BCVA was significantly better in the air group at 1 month (p = 0.021) but not at 3 months postoperatively (p = 0.561). Redetachments were recognized earlier in the air group (9.3 ± 0.5 days) compared with those in the control group (21.3 ± 7.4 days) (p = 0.041). Conclusions In cases of simple RRD with sufficient removal of subretinal fluid, air could be considered for use as gas tamponade. This trial is registered with KCT0002358.

Abstract
PURPOSE To describe a novel technique for securing sclerotomies after 20-gauge transconjunctival pars plana vitrectomy and determine the efficacy, and short-term safety in various vitreoretinal diseases. METHODS Retrospective chart review of consecutive cases that underwent 20-gauge transconjunctival pars plana vitrectomy with sclerotomy hydration was conducted. The main outcome measures included intraocular pressure, intraocular gas bubble size in postoperative Day 1, and early postoperative complications. Secondary outcomes included postoperative visual acuity at 1-month postoperative visit. RESULTS Five hundred and twenty-nine eyes were evaluated. Mean gas/air fill and mean intraocular pressure were 75.1% and 14.8 mmHg on postoperative Day 1. Seven eyes (1.32%) had hypotony (intraocular pressure <6 mmHg) on Day 1, which normalized in all eyes by Day 7 (P = 0.0083). On postoperative Day 7, mean intraocular pressure was 17.1 mmHg. Hypotony was associated with a preoperative diagnosis of retinal detachment (P = 0.022), and silicone oil tamponade (P = 0.017). Mean best corrected visual acuity was 20/320 preoperatively and 20/125 postoperatively at 1-month follow-up visit (P < 0.0001). Twenty-seven cases had intraoperative or postoperative complications (5.1%). Rate of complications was not associated with the type of tamponade (P = 0.076). CONCLUSION Twenty-gauge transconjunctival sutureless vitrectomy with sclerotomy hydration appears to be safe with a low rate of hypotony and complications, and good final visual outcome.

Abstract
PURPOSE To report anatomical and functional outcome of 20-gauge versus 25-gauge primary pars plana vitrectomy for management of complex rhegmatogenous retinal detachment in pseudophakic eyes. METHODS Prospective single-centre randomized comparative pilot trial. Fifty patients with retinal detachment (RD) not complicated by proliferative vitreoretinopathy grade B or C, who cannot be treated with a single meridional sponge, were randomized (1:1) from November 2006 to January 2010 to either 20-gauge or 25-gauge vitrectomy as first surgical intervention and followed up over a 12-month period, evaluating change in best-corrected visual acuity, anatomical success and intraocular pressure dysregulation. RESULTS Mean visual acuity improved by 0.88 (SD 0.67) from 1.22 logMAR (SD 0.63) to 0.34 logMAR (SD 0.31) in the 20-gauge group and by 0.53 (SD 0.91) from 0.86 logMAR (SD 0.73) to 0.34 logMAR (SD 0.46) in the 25-gauge group. Final anatomical success rate was 100% and primary success rate was 69% at 6 months of follow-up. In the 20-gauge group, the retina was attached after one single procedure in 18 eyes (72%) and in 21 eyes (84%) of the 25-gauge group. Two patients in the 25-gauge group had hypotony at the first postoperative day which normalized within 6 weeks. CONCLUSION In our series, transconjunctival sutureless 25-gauge and 20-gauge vitrectomy showed comparable results in pseudophakic RD not suitable for single sponge surgery with respect to visual outcome and retinal reattachment. Postoperative hypotony does not seem to be a significant problem of transconjunctival sutureless vitrectomy.

Abstract
Purpose: To review the characteristics and outcomes of patients who underwent pars plana vitrectomy (PPV) with scleral depressed vitreous shaving, 360 degree peripheral endolaser, and 14% C3F8 gas for rhegmatogenous retinal detachment (RRD). Materials and Methods: A retrospective review of a consecutive series of patients who underwent primary repair of RRD by PPV with scleral depressed vitreous shaving, 360 degree peripheral endolaser, and 14% perfluoropropane (C3F8) was conducted. Patients with less than 3 months follow-up, previous retinal surgery, and higher than grade B proliferative vitreoretinopathy were excluded. Results: Ninety-one eyes were included in the study. The mean age was 60.1 years. The mean follow-up was 13.7 months. The macula was detached in 63% (58/91) of the eyes. The reattachment rate after one surgical procedure was 95% (86/91) while overall reattachment rate was 100%. There was no statistically significant difference between reattachment rates of superior, nasal/temporal, or inferior RRDs. The mean final best corrected visual acuity (BCVA) was 20/40. Of all the patients, 66% of patients with macula-off RRDs had a final BCVA of 20/40 or better. Conclusions: PPV with scleral depressed vitreous shaving, 360 degree peripheral endolaser, and 14% C3F8 leads to successful anatomical reattachment with visual improvement in patients with primary RRD.

Abstract
BACKGROUND AND OBJECTIVE To compare outcomes of 25-gauge pars plana vitrectomy (PPV) and sulfur hexafluoride (SF6) gas for primary rhegmatogenous retinal detachment (RRD) associated with multiple-quadrant versus single-quadrant breaks. PATIENTS AND METHODS A retrospective study of patients with RRD who underwent 25-gauge PPV with breaks involving multiple quadrants (Group A) or versus a single quadrant (Group B). RESULTS One hundred eighteen eyes of 118 patients with a mean age of 60.4 years ± 11.8 years were reviewed, 27 with multiple-quadrant breaks and 91 with single-quadrant breaks. Single surgery anatomical success was achieved in 92.6% of Group A versus 93.4% of Group B patients (P = .88). The location and number of quadrants did not account for the variation in single surgery success or visual outcome. CONCLUSIONS RRD with multiple-quadrant breaks is not associated with worst outcomes than single-quadrant breaks when treated with 25-gauge PPV and SF6 gas.

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 incidence rates of cystoid macular edema (CME) and epiretinal membrane (ERM) formation after uncomplicated primary 23-G and 25-G retinal detachment (RD) repair and to identify risk factors associated with postoperative CME and ERM formation. METHODS This was a consecutive interventional case series of 587 eyes that underwent one RD repair with 23-G or 25-G pars plana vitrectomy (PPV) with scleral buckling. Epiretinal membrane and CME were confirmed by optical coherence tomography (OCT) and fluorescein angiography (FA). RESULTS A total of 587 eyes with a mean follow-up of 404 days had incidence rates of 35.1% for ERM and 15.2% for CME. The incidence of ERM after combined PPV and scleral buckling (48.4%) (n = 61) was greater (p<0.0001) compared to that after PPV alone (31.2%) (n = 144). CONCLUSIONS Epiretinal membrane and CME develop frequently after small-gauge RD repair. Pars plana vitrectomy combined with scleral buckling is associated with a higher incidence of ERM. Patients might benefit from increased use of OCT and FA to help rule out CME/ERM.

Abstract
PURPOSE This study was aimed to evaluate the efficacy and safety of 25-gauge sutureless vitrectomy in repairing primary rhegmatogenous retinal detachment (RRD) with air tamponade. DESIGN This is a prospective, clinic-based, case series. METHODS Twenty consecutive eyes of 20 patients with primary RRD caused by superior breaks of less than a month underwent transconjunctival sutureless 25-gauge vitrectomy with intraocular air tamponade. Patients who had a follow-up of less than 6 months were excluded. Outcome measures included best corrected visual acuity (BCVA), reattachment rate by a single procedure, final reattachment rate by additional procedures, and complications. RESULTS The mean follow-up was 10 months (range, 6-15 months). The proportion of eyes with BCVA of between 20/200 and 20/70 increased significantly from 15% at baseline to 65% on day 14 (P = 0.024). At final follow-up, 15%, 60%, and 25% had BCVA worse than 20/200, between 20/200 and 20/70, and better than 20/70, respectively. The mean BCVA was significantly better than baseline (logMAR, 1.4) by day 14 (logMAR, 0.87). The reattachment rate by a single procedure was 70%, and the final success rate was 100% after 1 additional procedure. The primary success rate increased to 77.8% after excluding 2 eyes with proliferative vitreoretinopathy grade C1. High myopia and large retinal break were 2 other conditions associated with failed primary reattachment. No postoperative complication was observed. CONCLUSIONS Selected eyes with primary RRD may gain the benefit of early visual recovery when treated with 25-gauge vitrectomy and air tamponade.

Abstract
AIM To assess the outcomes of combined 23-gauge sutureless vitrectomy and clear corneal phacoemulsification with intraocular lens implantation for rhegmatogenous retinal detachment (RRD) repair. METHODS This was a retrospective, consecutive, non-comparative, interventional case series of 30 eyes of 30 patients who underwent combined sutureless vitrectomy and clear corneal cataract surgery for the repair of RRD. The principal outcome measures were primary anatomical success rate, reasons for redetachment, final visual acuity, and surgical complications. RESULTS Primary reattachment was achieved in 27 eyes (90.0%). The reasons for redetachment (3 eyes, 10%) were incomplete laser retinopexy, persistent chronic subretinal fluid, and proliferative vitreoretinopathy, respectively. The logarithm of the minimum angle of resolution visual acuity (mean±SD) improved from 0.76±0.74 preoperatively to 0.21±0.37 6 months' postoperatively (P<0.0001). Postoperative hypotony was not detected, but 1 eye (3.3%) had increased intraocular pressure (30mmHg) with spontaneous resolution. No endophthalmitis developed during follow-up. Macular pucker was detected in 3 eyes (10.0%). CONCLUSION Combined 23-gauge sutureless vitrectomy and clear corneal phacoemulsification with intraocular lens implantation for RRD repair was proven safe and effective. It may provide not only the known advantages of conventional combined surgery, but also additional advantages such as less conjunctival fibrosis and the maintenance of stable intraocular pressure with low risks of postoperative hypotony and intraocular pressure elevation.

Abstract
PURPOSE This study compared clinical outcomes and complications between 23-gauge (23g) and 25-gauge (25g) transconjunctival sutureless vitrectomy in patients with proliferative diabetic retinopathy. STUDY DESIGN It was a retrospective study using data prospectively defined and collected. 80 eyes underwent 23g transconjunctival sutureless vitrectomy, and 80 eyes underwent 25g surgery using the same vitrectomy system by one surgeon. Primary outcome measures were best-corrected visual acuity, intraocular pressure (IOP), and incidence of intraoperative and postoperative complications. RESULTS Vision was significantly improved after intervention in both groups (p ≥ 0.0001). There was no significant difference in visual outcomes between the groups (p = 0.43) or in the type and frequency of retinal breaks occurring during surgery (p = 0.63). The 23g group had significantly more patients with a day 1 IOP of <6 mm Hg (p = 0.034) and significantly more patients requiring a sclerostomy suture postoperatively (p = 0.014). CONCLUSION AND MESSAGE Both gauges are equally effective for the treatment of proliferative diabetic retinopathy.

Abstract
Background The purpose of this study was to evaluate the outcome of 25-gauge vitrectomy for repair of rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy (PVR). Methods Twenty-seven eyes of 27 patients who had undergone 25-gauge vitrectomy for grade C PVR were investigated retrospectively. The surgical procedures, anatomic success, and best-corrected visual acuity were assessed. Results The mean number of operations was 1.4 (range 1–4). During the 25-gauge vitrectomy, 20-gauge instruments were needed in eleven eyes (40.7%) to remove resilient fibrous preretinal membranes, to extract subretinal proliferations, or to remove or infuse silicone oil. The retina was reattached in 21 eyes (77.8%) after the initial vitrectomy and in 25 eyes (92.6%) at the final examination. The mean best-corrected visual acuity in logarithm of the minimal angle of resolution units was 1.36 ± 0.81 before vitrectomy and 0.79 ± 0.71 at one month, 0.73 ± 0.72 at 3 months, 0.73 ± 0.75 at 6 months, and 0.75 ± 0.78 at 12 months after vitrectomy. The best-corrected visual acuities were significantly improved compared with the preoperative ones at all postoperative assessments (P<0.001). Conclusion Twenty-five gauge vitrectomy is a relatively safe and efficacious method of treating RRD with PVR, although combined use of 20-gauge instruments may be needed for certain surgical procedures.

Abstract
PURPOSE To investigate the role of intravitreal injection of triamcinolone acetonide (IVTA) in preventing photoreceptor apoptosis in eyes with rhegmatogenous retinal detachment (RRD) by measuring cytokine levels in the aqueous humor before and after IVTA. DESIGN Prospective, nonrandomized, interventional case series. METHODS setting: Institutional. patients: Nineteen eyes of 19 consecutive patients with RRD. intervention: All 19 eyes underwent IVTA 1 day before 25-gauge vitrectomy. Seventeen eyes free of retinal vascular disease served as controls. main outcome measure: Both baseline and 1 day post-IVTA measurements were made of the relative concentrations of 15 soluble factors (3 cytokines, 7 chemokines, and 5 growth factors). The associations with clinical findings, including macular status, were then analyzed. RESULTS Elevated monocyte chemotactic protein 1 (MCP-1), macrophage inflammatory protein 1β (MIP-1β), and interferon γ-induced protein 10 (IP-10) in eyes with RRD were significantly reduced after IVTA. MCP-1 levels were significantly correlated with MIP-1β and IP-10 before and after IVTA. The decreases in MCP-1, MIP-1β, and IP-10 were also closely correlated to each other. Both before and after IVTA, MCP-1 was higher in eyes with macula-off RRD than in eyes with macula-on RRD. CONCLUSIONS IVTA suppressed elevated levels of intraocular MCP-1, MIP-1β, and IP-10 in eyes with RRD. The decrease in the aqueous levels of each of these factors was significantly correlated with the others. In addition to MCP-1, MIP-1β and IP-10 might potentially be additional target molecules for RRD therapy.

Abstract
Background and methods We compared surgical procedures and outcomes, including duration of recovery period, in eyes with proliferative diabetic retinopathy that underwent 25-gauge microincision vitrectomy surgery with those that underwent 20-gauge vitrectomy. Seventy-two eyes from 53 patients that underwent 20-gauge vitrectomy in 2006 and 87 eyes from 55 patients that underwent 25-gauge vitrectomy in 2010 were studied. The surgical procedures, ie, number of vitreous procedures, operating time, and ratio of type of intraocular tamponade were compared between the two groups. In addition, the outcomes, ie, postoperative complications, anatomical success, postoperative best-corrected visual acuity (BCVA), and duration of hospitalization as an indicator of the postoperative recovery period were also compared. Results There were no significant differences in surgical procedures or ratio of cases with postoperative complications between cases with 20-gauge and 25-gauge vitrectomy. The final anatomical success rate was 100% in the two groups. BCVA at 6 months after the final vitrectomy was significantly better than the preoperative BCVA for both types of vitrectomy (P < 0.05), and was not significantly different between the two groups. The average duration of hospitalization was 19.5 days after 20-gauge vitrectomy, which was significantly longer than the 11.0 days after 25-gauge vitrectomy (P < 0.001). Conclusion These results indicate that the anatomical and functional improvements after 25-gauge microincision vitrectomy surgery are not significantly different from those after 20-gauge vitrectomy in eyes with proliferative diabetic retinopathy. However, the significantly shorter recovery period after 25-gauge microincision vitrectomy surgery suggests that it is less traumatic than 20-gauge vitrectomy.

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
AIM To investigate cases with conjunctival pigmentation originating from sclerotomy sites after 23-gauge microincisional vitrectomy surgery (MIVS). METHODS This is a retrospective study comprised of 185 eyes from 185 consecutive patients who underwent 23-gauge MIVS. The authors investigated the incidence and the clinical factors associated with conjunctival pigmentation, including indication of vitrectomy and surgical procedures. RESULTS Eight eyes (4.3%) from 185 eyes showed conjunctival pigmentation after surgery within 7 days postoperatively. Light microscopic examination of excised tissue showed infiltration of abundant dark brownish colored melanophages with surrounding scattered, finely granular, melanin pigments. C3F8 gas tamponade (OR, 9.4; 95% CI, 1.9-44.5; P=0.005) was significantly associated with conjunctival pigmentation. The mean surface area (21.26±2.21 mm(2)) of three eyes with C3F8 tamponade was significantly larger than that of five eyes (2.51±0.73 mm(2)) without tamponade (P=0.025). Neither leakage nor hypotony was found. CONCLUSIONS Intraocular melanin pigments could prolapse through the sclerotomy site and cause conjunctival pigmentation after 23-gauge MIVS. Thus, preoperative warning is necessary in patients with 23-gauge MIVS.

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.
