Purpose: To investigate outcomes and presenting characteristics for subjects undergoing pars plana vitrectomy for ocular trauma. Methods: Retrospective study of 113 patients who underwent pars plana vitrectomy for severe ocular trauma at [name deleted to maintain the integrity of the review process] between 1999 and 2018. Data were collected on age, gender, initial and final visual acuity (LogMAR), mode of injury, type of injury, number of surgeries performed, follow-up duration, type of tamponade, presence of phthisis, and retinal detachment. The Birmingham Eye Trauma Terminology System (BETTS) was employed. Results: We identified assault and contusion injuries to be the most common mode and type of ocular injury in our cohort. Furthermore, through follow-up we noted a varied number of operations required by patients presenting with ocular trauma and a statistically significant improvement in visual acuity from 1.73 (±0.86) LogMAR to 1.17 (±1.03; p <0.01) LogMAR. A statistically significant difference in final visual acuity was also noted between BETTS classified type of injury groups (p < 0.01). Notably, only 7.3% and 8.2% of patients developed phthisis or a persisting retinal detachment, respectively, during follow-up. Conclusion: Our study demonstrates that ocular trauma requiring pars plana vitrectomy can require a varied number of operations with a guarded visual prognosis. However, a small percentage will proceed to develop phthisis following intervention.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and needs further surgery. The purpose of this study is to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD.Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included the causative factors, visual outcomes of RD recurrence, and the perioperative factors most affecting the recurrence of RD.Results After retinal reattachment, we observed recurrence of RD after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most recurrence (69%) occurred within 6 months after surgery. Univariate analysis showed that the primary risk factor significantly associated with recurrent RD was the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C ( P = 0.003). Logistic regression analysis showed that a PVR ≥ Grade C (odds ration [OR]: 9.421, 95% confidence interval [CI]: 2.432 - 56.39; P =0.020) was a significant predictor for the development of recurrent RD. The recurrence of RD resulted in a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit compared with the reattachment group ( P =0.000). Eyes with PVR prior to primary surgery or at the diagnosis of re-detachment showed a worse final BCVA.Conclusions The presence of PVR ≥ Grade C was the predominant risk factor for the recurrence of RD. PVR prior to primary surgery, or at the diagnosis of re-detachment, limited the recovery of final visual acuity.

ABSTRACT Introduction Penetrating and perforating ocular trauma are often devastating and may lead to complete visual loss in the traumatized eye and subsequent compromise of the fellow eye. A significant proportion of traumatic injuries are complex, often requiring vitreoretinal intervention to preserve vision. A retrospective analysis at a level 1 trauma center was performed to evaluate the time course, incidence, and outcomes following pars plana vitrectomy (PPV) after traumatic ocular injury and initial globe repair. Materials and Methods Eyes that underwent open globe repair following ocular trauma at Brooke Army Medical Center, between January 1, 2014 and December 30, 2016 were analyzed. Specific factors evaluated include mechanism of injury, defect size and complexity, ocular trauma score, zone of injury, associated orbital trauma, and time from injury to surgical intervention. A subset analysis was conducted specifically on eyes requiring subsequent PPV for vision preservation because of vitreoretinal disease. Surgical outcomes, time to secondary intervention, and complication rates were then assessed. Results In total, 70 eyes requiring open globe repair were examined, with 43 having undergone PPV. Average and median time to vitrectomy were 18.8 and 8 days, respectively. Eyes that underwent PPV were more likely to have an afferent papillary defect, vitreous hemorrhage, intraocular foreign body, and retinal detachment at the time of initial injury (although the latter two factors were not statistically significant), and were more likely to receive penetrating keratoplasty. Proliferative vitreoretinopathy occurred in 37.2% of eyes that underwent PPV, versus 3.7% of those that did not (P = 0.0013). Timing of PPV (i.e., before or after 14 days) had no statistically significant effect on the rate of PVR (Table I). Eyes that underwent PPV showed an improvement of visual acuity from average 2.5 logMAR following initial injury to 1.5 logMAR 6 months after PPV, equivalent to 18.7 Early Treatment Diabetic Retinopathy Study (ETDRS) letters gained, versus 37.7 ETDRS letters gained in eyes without PPV. Among PPV eyes, early repair (&lt;14 days) was associated with greater improvement in visual acuity. Conclusion Overall, patients requiring PPV following open globe repair generally had more severe injuries and worse 6-month postoperative visual acuity. Patients who underwent more expedited vitrectomy showed greater improvement in visual acuity as measured by ETDRS letters gained.

Purpose. To identify the incidence of endophthalmitis and visual outcomes in eyes with Boston type 1 keratoprosthesis combined with pars plana vitrectomy and silicone oil insertion (KPro + PPV + SOI) as compared to eyes receiving Boston type 1 keratoprosthesis (KPro) alone. Patients and Methods. Retrospective chart review of 29 eyes of 27 patients with KPro having at least 12-month follow-up. Thirteen of these eyes had hypotony and/or retinal detachment in addition to corneal pathology and thus received KPro + PPV + SOI. Polymyxin-trimethoprim with a quinolone was used as chronic topical antibiotic prophylaxis in both groups after the first postoperative month. Outcome measures recorded at the 1-, 3-, 6-, 12-, and 24-month follow-up visits included best-corrected visual acuity (BCVA) and rates of postoperative complications. Results. All the patients had completed 24-month follow-up except one case in the KPro group who lost to follow-up after 12-month visit. In the KPro + PPV + SOI group, no eyes had developed endophthalmitis by the 24-month follow-up visit versus 5 eyes of 5 patients in the uncombined KPro group (P=0.048). The 2-year cumulative endophthalmitis incidence was 31.2% in the KPro group versus zero in the KPro + PPV + SOI group (P=0.030). Four of these 5 eyes had vitreous taps with positive cultures; 2 were positive with Staphylococcus aureus, 1 with coagulase-negative staphylococci, and 1 with Streptococcus pneumoniae. Other complications included KPro extrusion (1 in each group), retinal detachment (2 in the KPro and 1 in the KPro + PPV + SOI group), newly developed glaucoma (2 in each group), and retroprosthetic membrane (9 in the KPro and 5 in the KPro + PPV + SOI group). The KPro group had better average preoperative BCVA compared to those of the KPro + PPV + SOI group (−2.29 ± 0.72 LogMAR, versus −2.95 ± 0.30 LogMAR; P=0.004). No statistically significant difference in BCVA was noted in subsequent follow-up visits. Conclusion. The addition of PPV and SOI to the KPro implantation in the eyes with corneal pathology, as well as hypotony and/or retinal detachment, is a safe and effective procedure for visual rehabilitation. Pars plana vitrectomy and silicone oil insertion may have a protective effect against the development of postoperative endophthalmitis in eyes receiving KPro.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and requires further surgery. The purpose of this study was to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD. Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included causative factors, visual outcomes related to the recurrence of RD, and the perioperative factors most affecting the recurrence of RD. Results After retinal reattachment, we observed RD recurrence after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most causes of recurrence (69%) occurred within 6 months of surgery. Univariate analysis showed that the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C was significantly associated with recurrent RD (P = 0.003). Logistic regression analysis further showed that a PVR ≥ Grade C (odds ratio [OR]: 9.421; 95% confidence interval [CI]: 2.432 - 56.39; P = 0.020) was a significant predictor for the development of recurrent RD. Compared with the reattachment group, the recurrence group exhibited a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit (P = 0.000). Eyes with PVR prior to primary surgery, or at the diagnosis of re-detachment, showed a worse final BCVA. Conclusions Our analysis shows that the predominant risk factor for the recurrence of RD is a PVR ≥ Grade C. PVR prior to primary surgery, or at the diagnosis of re-detachment, was also shown to limit the recovery of final visual acuity.

AIM: To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis. METHODS: Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy (PPV) combined with scleral shortening were reviewed. Axial length (AL), the height of macular retinoschisis, the height of retinal detachment if existed, the diameter of macular hole if existed and best corrected visual acuity (BCVA) were obtained. The preoperative and postoperative parameters were compared. RESULTS: At postoperative 24mo, the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51 μm (t=8.064, P<0.0001; Z=-5.086, P<0.0001) respectively. In addition, the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38 μm and 183.68 μm (Z=-4.457, P=0.000008; Z=-2.983, P=0.003) respectively. Meanwhile, the postoperative BCVA was improved markedly (Z=-2.126, P=0.033). CONCLUSION: Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis, whether or not macular hole and retinal detachment are present.

Aim. To compare the anatomic and visual outcomes of 25-gauge (25G), and 27-gauge (27G) transconjunctival sutureless pars plana vitrectomy (TSV) for the management of primary rhegmatogeneous retinal detachment (RRD).Design. A retrospective nonrandomized clinical trial.Methods. A retrospective comparative analysis of 62 consecutive eyes from 62 patients with 6 months of follow-up was performed.Results. Thirty-two patients underwent 25G TSV, and 30 patients underwent 27G TSV for the treatment of primary RRD. There was no significant difference in baseline demographic and preoperative ocular characteristics between the two groups. The initial and final anatomical success rates were 93.8% and 100% in 25G TSV and 96.7% and 100% in 27G TSV, respectively (p=1andp=1, resp.). Preoperative best-corrected visual acuity (BCVA) (logMAR) was 0.44 ± 0.69 and 0.38 ± 0.61 for 25G and 27G TSV, respectively (p=0.73). The final follow-up BCVA was 0.07 ± 0.25 and −0.02 ± 0.17 for 25G and 27G TSV, respectively (p=0.16). The final BCVA was significantly better than the preoperative BCVA in both groups (p=0.02andp=0.002, resp.). Preoperative intraocular pressure (IOP) (mmHg) was 13.0 ± 3.5 in 25G TSV and 14.3 ± 2.8 in 27G TSV (p=0.11). IOP did not statistically significantly change in both groups during the follow-up period (p=0.63andp=0.21, resp.).Conclusion. The 27G TSV system is safe and useful for RRD treatment as 25G TSV.

Abstract Purpose The purpose of this study is to report the safety and efficacy of pars plana glaucoma drainage devices with pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement in patients with refractory glaucoma. Methods Retrospective case series of 28 eyes of 28 patients who underwent combined pars plana glaucoma drainage device and pars plana vitrectomy between November 2016 and September 2019 at Massachusetts Eye and Ear. Main outcome measures were intraocular pressure (IOP), glaucoma medication burden, best corrected visual acuity, and complications. Statistical tests were performed with R and included Kaplan-Meier analyses, Wilcoxon paired signed-rank tests, and Fisher tests. Results Mean IOP decreased from 22.8 mmHg to 11.8 mmHg at 1.5 years (p = 0.002), and mean medication burden decreased from 4.3 to 2.1 at 1.5 years (p = 0.004). Both IOP and medication burden were significantly lower at all follow-up time points. The probability of achieving 5 < IOP ≤ 18 mmHg with at least 20% IOP reduction from preoperative levels was 86.4% at 1 year and 59.8% at 1.5 years. At their last visit, three eyes (10.7%) achieved complete success with IOP reduction as above without medications, and 14 eyes (50.0%) achieved qualified success with medications. Hypotony was observed in 1 eye (3.6%) prior to 3 months postoperatively and 0 eyes after 3 months. Visual acuity was unchanged or improved in 23 eyes (82.1%) at their last follow-up. Two patients had a visual acuity decrease of > 2 lines. Two eyes required subsequent pars plana vitrectomies for tube obstruction, and one eye had transient hypotony. Conclusions The results of pars plana glaucoma drainage device and pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement are promising, resulting in significant IOP and medication-burden reductions through postoperative year 1.5 without additional risk of postoperative complications. Inserting glaucoma drainage devices into an existing vitrectomy sclerotomy site may potentially save surgical time by obviating the need to create another sclerotomy for tube placement and suture one of the vitrectomy ports.

Purpose. To quantify the frequency of visual loss after successful retinal detachment (RD) surgery in macula-on patients in a multicentric, prospective series of RD.Methods. Clinical variables from consecutive macula-on RD patients were collected in a prospective multicentric study. Visual loss was defined as at least a reduction in one line in best corrected visual acuity (VA) with Snellen chart. The series were divided into 4 subgroups: (1) all macula-on eyes (n=357); (2) macula-on patients with visual loss at the third month of follow-up (n=53) which were further subdivided in (3) phakic eyes (n=39); and (4) pseudophakic eyes (n=14).Results. Fifty-three eyes (14.9%) had visual loss three months after surgery (n=39phakic eyes;n=14pseudophakic eyes). There were no statistically significant differences between them regarding their clinical characteristics. Pars plana vitrectomy (PPV) was used in 67.2% of cases, scleral buckle in 57.7%, and scleral explant in 11.9% (36.1% were combined procedures).Conclusions. Around 15% of macula-on RD eyes lose VA after successful surgery. Development of cataracts may be one cause in phakic eyes, but vision loss in pseudophakic eyes could have other explanations such as the effect of released factors produced by retinal ischemia on the macula area. Further investigations are necessary to elucidate this hypothesis.

Purpose. We aimed at reminding that X-linked retinoschisis may also be seen in female patients and share our vitreoretinal surgical experience. Methods. The patient underwent pars plana vitrectomy including the closure of the macular holes with inverted ILM flap technique bilaterally. Lens extractions were performed by phacoemulsification during the removal of silicone oil endotamponade. Patient. An 18-year-old girl with X-linked retinoschisis and large macular holes in both eyes presented to the clinic of ophthalmology. It was confirmed that the patient had RS1 mutation Results. Nine-month-follow-up was uneventful for retinal findings. Significant improvement in visual acuity was achieved, and macular holes were remained closed. Conclusion. In cases with large macular holes due to XLR, an inverted ILM flap technique might be safe and effective. Four-month-silicone-endotamponade might be sufficient.

Purpose.To determine the efficacy and safety of preoperative intravitreal conbercept (IVC) injection before vitrectomy for proliferative diabetic retinopathy (PDR).Methods.107 eyes of 88 patients that underwent pars plana vitrectomy (PPV) for active PDR were enrolled. All patients were assigned randomly to either preoperative IVC group or control group. Follow-up examinations were performed for three months after surgery. The primary bioactivity measures were severity of intraoperative bleeding, incidence of early and late recurrent VH, vitreous clear-up time, and best-corrected visual acuity (BCVA) levels. The secondary safety measures included intraocular pressure, endophthalmitis, rubeosis, tractional retinal detachment, and systemic adverse events.Results.The incidence and severity of intraoperative bleeding were significantly lower in IVC group than in the control group. The average vitreous clear-up time of early recurrent VH was significantly shorter in IVC group compared with that in control group. There was no significant difference in vitreous clear-up time of late recurrent VH between the two groups. Patients that received pretreatment of conbercept had much better BCVA at 3 days, 1 week, and 1 month after surgery than control group. Moreover, both patients with improved BCVA were greater in IVC group than in control group at each follow-up.Conclusions.Conbercept pretreatment could be an effective adjunct to vitrectomy in accelerating postoperative vitreous clear-up and acquiring stable visual acuity restoration for PDR.
