Abstract
PURPOSE OF REVIEW To compare outcomes of 27-gauge and 23-gauge pars plana vitrectomy (PPV) for treatment of vitreoretinal diseases. RECENT FINDINGS Sixty-eight patients undergoing microincisional PPV for treatment of vitreoretinal diseases were randomized 1 : 1 to 27-gauge or 23-gauge surgery with a 7500 cuts-per-minute vitrectomy probe. The most common reasons for vitrectomy were epiretinal membrane (49%) and vitreous hemorrhage (24%). Mean ± standard deviation (SD) changes from immediate preoperative to immediate postoperative intraocular pressure were -0.40 ± 6.60 mmHg in the 27-gauge and -3.05 ± 7.64 mmHg in the 23-gauge group (adjusted mean difference 2.42 mmHg, 95% lower confidence limit 0.64, P = 0.013), but these changes were not associated with primary reason for vitrectomy (P = 0.065). Mean ± SD conjunctival edema grades in the 27-gauge and 23-gauge groups 1 week after surgery were 0.02 ± 0.124 and 0.10 ± 0.246, respectively (least squares mean difference -0.09, 95% upper confidence limit -0.03, P = 0.004), and were 0.01 ± 0.122 and 0.12 ± 0.338, respectively, at the probe incision site. Conjunctival edema grades were similar in both groups at 1 and 3 months. Mean ± SD pain ratings on postoperative day 1 - an indicator of patient comfort - were similar in the two groups. SUMMARY Smaller diameter vitrectomy instruments are associated with smaller reductions in immediate postoperative intraocular pressure.

Abstract
PURPOSE To evaluate the incidence, characteristics and risk factors for rhegmatogenous complications of transconjunctival sutureless 23-gauge vitrectomy (TSV) in macular surgery. The results were correlated with those reported in the literature. METHODS Multicentric retrospective study of a cohort of patients undergoing macular surgery by 23-gauge TSV between January 2009 and June 2010. RESULTS Four hundred and seventy-four patients divided into: epiretinal membrane (MEM) (n=279), vitreomacular traction (n=65) and idiopathic macular hole n=130. Forty-three percent of patients were pseudophakic. Posterior vitreous detachment (PVD) was absent in 60% of cases and was therefore systematically performed intraoperatively. It was seen that 1.7% of patients developed retinal tears and 2.7% retinal detachment with a higher incidence in the vitreomacular traction (VMT) group and the group in which the PVD was performed intraoperatively. Rhegmatogenous lesions were localized mainly in the inferior retina in the macular hole group. DISCUSSION Results are consistent with the TSV literature. Their location does not appear to be related to the sclerotomies or handedness as in 20-gauge surgery, probably due to sclerotomy trocars. Localization of rhegmatogenous lesions in the inferior retina in macular hole surgery suggests a role of gas in this subgroup. In addition to instrument-retinal touch, the performance of a surgical PVD represents a major independent risk factor for retinal detachment (RD). CONCLUSION Even with limited macular surgery, it is essential to check the retinal periphery for 360 degrees, especially for VMT and intraoperative PVD, and especially inferiorly in the case of gas tamponnade.

Abstract
PURPOSE To study the safety of 20-gauge transconjunctival sutureless vitrectomy. METHODS Clinical data of patients who underwent 20-gauge transconjunctival sutureless vitrectomy for the first time, for various disorders, were reviewed retrospectively. The main outcome measures were the number of sclerotomies requiring suturing as well as the intra- and postoperative complications. RESULTS A total of 179 operations were performed. Indications for vitrectomy included 68 idiopathic epiretinal membranes, 26 macular holes, 23 phakic and 16 pseudophakic retinal detachments, and 46 various other, less common etiologies. Of these 179 operations, 166 (93%) were sutureless. Of the 537 sclerotomies created, 25 (5%) received a single transconjunctival-scleral suture. Intraoperative complications included premature dislodging of the cannulas in 2 sclerotomies and an iatrogenic horseshoe tear at 1 sclerotomy site. Postoperative complications comprised transient hypotony in 14 cases, subconjunctival gas in 2 cases, and choroidal effusion in 1 case. No serious complications (such as endophthalmitis) were observed. CONCLUSION 20-gauge transconjunctival sutureless vitrectomy can be considered safe, as the intra- and postoperative complications observed are neither numerous nor significant. Sclerotomies appear to be safe and relatively easy to perform, without compromising the advantages of sutureless surgery.

Abstract
AIM To report the effectiveness and safety of primary 23-Gauge (G) vitreoretinal surgery for rhegmatogenous retinal detachment (RRD). METHODS In this retrospective study, 49 eyes of 49 consecutive patients who underwent primary 23-G transconjunctival sutureless vitrectomy (TSV) for RRD between January 2007 and July 2009 at our institution were evaluated. RESULTS Mean follow-up time was 8.9±7.7 months (1-28 months). Retinal reattachment was achieved with a single operation in 47(95.9%) of 49 eyes. In two eyes (4.1%), retinal redetachment due to new breaks was successfully treated with reoperation using the 23-G TSV system. Mean logMAR visual acuity was 2.01±0.47 preoperatively and 1.3±0.5 postoperatively (P<0.001, Paired t-test). Mean preoperative intraocular pressure (IOP) was 14.1±2.8mmHg. Mean postoperative IOP was 12.3±3.6mmHg at 1 day, 13.1±2.1mmHg at 1 week, 14.3±2.2mmHg at 1 month. Iatrogenic peripheral retinal break was observed in 1 eye (2.0%) intraoperatively. No sutures were required to close the scleral or conjunctival openings, and no eyes required convertion of surgery to 20-G vitrectomy. CONCLUSION Primary 23-G TSV system was observed to be effective and safe in the treatment of RRD.

Abstract
BACKGROUND The surgery of the idiopathic epimacular membrane has gained from the advent of 25-gauge transconjunctival vitrectomy (TSV) initiated by Fujii in 2002. PATIENTS AND METHODS In this retrospective study, we tested 50 patients operated on for epimacular membrane with 25-gauge TSV at the Quinze-Vingts National Ophthalmology Hospital in Paris from December 2004 to June 2006. RESULTS No postoperative endophthalmitis, major hypotonia, or sclerotomy leakage were observed. However, two cases (4%) of retinal detachment and 47% postoperative cataract were noted at 3 months. After evolving 3 months later, distant and close visual acuity were significantly improved. CONCLUSION TSV appears to be a useful method for epimacular membrane ablation.

Abstract
PURPOSE The purpose of this study was to evaluate the incidence of retinal detachment (RD) after a small-incision, sutureless vitrectomy compared with conventional 20-gauge vitrectomy in macular hole and epiretinal membrane surgery and to investigate the clinical features and possible causative agents. METHODS The authors performed a computerized database analysis to retrospectively identify all patients who underwent vitrectomy at our institution between March 2001 and March 2009 for epiretinal membrane and macular hole. The authors further investigated the clinical features of patients who showed RD within 6 months postoperatively in the study eye. The incidence rate and clinical features of the affected eyes were analyzed. RESULTS During the study period, 2,432 vitrectomies were performed for epiretinal membrane and macular hole. The incidence of RD was 1.7% (31 of 1,862) after sutureless 25- or 23-gauge vitrectomy and 1.2% (7 of 570) after conventional 20-gauge vitrectomy. The difference was not statistically significant. Moreover, the difference between 25-gauge surgery (28 of 1,580) and 23-gauge surgery (3 of 282) was not statistically significant. In 9 of 38 cases (24%), the RD was probably attributable to the underlying pathology (e.g., an unclosed macular hole and reopening of preexisting retinal tears). Twenty-one eyes (76%) presented new retinal tears that were not related to the sclerotomies in both groups. CONCLUSION The incidence of RD after macular surgery is not increased in small-gauge, sutureless vitrectomy compared with the standard 20-gauge procedure. In most cases, the RD is not caused by the surgical technique itself but caused by new retinal breaks.

Abstract
BACKGROUND AND PURPOSE To identify possible agents causing retinal detachment following small-incision, sutureless vitrectomy. METHODS Computer-based, retrospective analysis to identify all patients who had undergone small-incision sutureless vitrectomy and presented retinal detachment (RD) in the study eye within 6 months postoperatively. The clinical charts of these patients were reviewed. RESULTS The investigation involved 2,598 small-incision, sutureless vitrectomies. Thirty-seven eyes presented subsequent RD. Indications for sutureless vitrectomy were idiopathic epiretinal membrane (n = 15), idiopathic macular hole (n = 15), recurrent macular hole (n = 1), rhegmatogenous retinal detachment (n = 5) and vitreous haemorrhage due to proliferative diabetic retinopathy (PDR) (n = 1). The median time between sutureless vitrectomy and RD presentation was 51 days (range 11-173 days); mean 59 days (SD 46.5). In 14 eyes (38%), the RD was most likely due to the underlying pathology (e.g., unclosed macular hole, reopening of pre-existing retinal tears, worsening of PDR). Twenty-three eyes (62%) presented with new retinal tears that were not in the proximity of the sclerotomies. CONCLUSION In most cases, the RD was not caused by the sutureless technique itself, but was most likely due to the underlying pathology, or due to new retinal tears that were not in the proximity of the sclerotomies.

Abstract
OBJECTIVES To assess the complication rates of pars plana vitrectomy (PPV) among older Americans and to determine whether rates of adverse events and additional operations have changed during the past decade. METHODS Claims data were reviewed to identify all adults aged 68 years or older in the 5% Medicare sample who underwent their first PPV during 1994-1995, 1999-2000, and 2004-2005. One-year rates of severe complications (endophthalmitis, suprachoroidal hemorrhage, or retinal detachment), less severe complications, receipt of an additional operation, and blindness were calculated and compared among the 3 groups using Cox regression. Analyses were adjusted for prior adverse events (during the previous 3 years), demographic characteristics, and comorbid conditions. RESULTS The 1994-1995, 1999-2000, and 2004-2005 cohorts had 3263, 5064, and 5263 patients, respectively. The 1-year severe complication rates did not differ among the 3 groups (range, 4.8%-5.5%). The hazard of a less severe complication or an additional operation was higher in the 2004-2005 cohort than in the earlier cohorts (P < .05 for all comparisons). The hazard of endophthalmitis was higher in black individuals (P = .07) and those of other races (P = .02) than in white patients. CONCLUSIONS During the past decade, rates of severe complications after PPV remained stable, but rates of less severe complications and subsequent operations increased. Future studies should explore the potential factors that explain these changes and the alarming elevated incidence of post-PPV endophthalmitis among nonwhite individuals.

Abstract
The formation of epiretinal membranes associated with proliferative vitreoretinopathy is known to be a complication of Terson syndrome. We report the first case of a 25-Gauge transconjunctival sutureless vitrectomy performed in one eye as treatment for an epiretinal membrane secondary to a case of Terson syndrome (most probably due to a history of subdural hematoma in childhood). Following a review of the current literature on the subject we report the physiopathologic mechanisms of Terson syndrome and the explanation for the proliferative vitreoretinopathy formation.
