Purpose.Ocular siderosis (OS) is a sight threatening complication of retained iron-containing Intraocular Foreign Body (IOFB). Successful localization of the IOFB and timely removal are crucial to its management. The purpose of this study was to review the presentation, management, and outcome of OS at our institution.Methods. A retrospective case series of eyes with OS that underwent IOFB removal from January 2009 to March 2015 at our institution.Results. OS was seen in 9 eyes of 9 patients during the study period. There were 8 males and 1 female with an age range of 31.6 years. An IOFB was in all the eyes. The most common features of siderosis were cataract and pigmentary retinopathy seen in 6 (67%) and 4 (44%) eyes, respectively. Electroretinogram (ERG) readings were reduced in the 9 eyes. The IOFB was removed by pars plana vitrectomy in all the cases with improvement in ERG amplitudes occurring postoperatively in 7 (78%) eyes.Conclusion.A retained iron-containing IOFB can manifest itself after several years with features of OS. A careful clinical and radiologic evaluation is imperative in patients with history suggestive of penetrating ocular injury to rule out retained or occult IOFB and thus prevent this catastrophic condition.

Introduction: Endophthalmitis following cataract surgery is a rare but devastating ocular complication where delay in treatment not only results in vision loss but also in difficulty to save the eye ball. Objective: To explore the clinical profile and visual outcome following pars plana vitrectomy (PPV) in acute endophthalmitis after cataract surgery. Materials and methods: This is a retrospective interventional case series study conducted at Tilganga Institute of Ophthalmology (TIO), Nepal. All consecutive cases of acute endophthalmitis following cataract surgery treated with PPV from January 2005 to August 2010 were included in the study. Results: There were a total of 34 cases (34 eyes) treated with PPV. The age range was 8 - 93 years with mean age of 56.9 ± 19.5 years. The mean duration of presentation and duration following cataract surgery was 7.7 ± 8.1days and 13 ± 11.6 days respectively. Small incision cataract surgery was done in 75 % of cases followed by phacoemulsification (15.6 %). The mean duration of the last follow -up was 4.3 months. Vision was improved in two-thirds of cases (67.67 %) with a good vision of 6/18 or better in 17.6 %. Among the available vitreous samples of 22 cases, 36.36 % had an abnormality in Gram and Giemsa stains and culture was positive in 13.6 % of cases. Conclusion: Despite the late presentation, the majority of eyes were salvaged with improvement of vision in 67.67 %, with a good vision of 6/18 or better in 17.6 4 % of cases following PPV in acute post operative endophthalmitis.

Abstract Background: This study aimed to determine the efficacy and complications of intravitreal chemotherapy-assisted endoresection for refractory International Classification of Retinoblastoma (ICRB) group D retinoblastoma in monocular patients.Methods: In this retrospective case series, intravitreal chemotherapy-assisted endoresection by pars plana vitrectomy was performed in 11 eyes with refractory ICRB group D retinoblastoma unresponsive to standard therapies in monocular patients.Results: Across a mean follow-up period of 42.7 months, globe salvage was attained in all 11 eyes (100%). There were no cases of extra-ocular tumour seeding or remote metastasis. In 9 eyes (81.8%), tumour control was achieved with one pars plana vitrectomy; in 2 cases (18.2%), repeated treatment, such as laser therapy, intravitreal chemotherapy or a second pars plana vitrectomy, was needed. Retinal reattachment was achieved in all 4 eyes (100%) with previous retinal detachment. Four eyes (36.4%) required subsequent cataract surgery due to secondary cataract. Ten eyes (90.9%) had improvement in best-corrected visual acuity at the last follow-up.Conclusion: Intravitreal chemotherapy-assisted endoresection appears to be a safe and effective globe-salvaging method for refractory group D retinoblastoma. It is a promising alternative to enucleation and a supplementary therapeutic strategy for those unresponsive to standard therapies, especially for the monocular retinoblastoma patients.

Abstract Sympathetic Ophthalmia (SO) is a rare disease that presents as a bilateral, diffuse, granulomatous panuveitis. Sympathetic Ophthalmia is a clinical diagnosis with history of penetrating ocular injury in the inciting eye and presence of panuveitis in the sympathizing eye. Though early enucleation is believed to minimize the risk, there have been reports of SO even after enucleation of inciting eyes. The possible association between vitrectomy and SO has been initially proposed by Gass [9] and later studied extensively in a large cohort in the UK with an estimated SO risk of 1 in 799 vitrectomies [11]. There have been several case series and reports of SO following vitrectomy, however only three documented cases of SO following vitrectomy without use of silicone oil. These cases demonstrated an onset of SO ranging between 4 weeks to 2 months. We present a patient with SO in the sympathizing eye presenting 16 days after an uncomplicated 23-gauge (23G) sutureless pars plana vitrectomy (PPV) without the use of silicone oil.

Recent reports suggest that the use of an outpatient-based procedure (pneumatic retinopexy, PR) for retinal detachment repair should be encouraged within the UK, especially in light of Covid-19 and possible restrictions/competing demands on access to operating theatres. It is therefore essential that patients receive comprehensive information about the risks and benefits of this approach compared with a formal surgical repair either by pars plana vitrectomy (PPV) and/or scleral buckling (SB). We report a retrospective case series of retinal detachments (RD) satisfying the strict selection criteria for PR but who were managed with formal surgery. Single-operation success rate for PPV/SB at six months follow-up was 93.8% in our study, higher than published primary success rates for PR (60–80%). When counselling patients for possible PR, the ease, speed and potentially reduced co-morbidity of an outpatient-based procedure needs to be balanced against its significantly higher failure rate in comparison with primary PPV/SB.

AbstractWe aimed to investigate the efficacy and safety of primary retropupillary iris claw intraocular lens (R-IOL) implantation in patients with complete intraocular lens (IOL) dislocation. In this single-center retrospective case series, we reviewed the medical records of patients who underwent R-IOL implantation surgery with pars plana vitrectomy for the treatment of IOL dislocation between September 2014 and July 2019. The primary outcome was change in visual acuity (VA) up to 24 months postoperatively. The secondary outcomes included changes in intraocular pressure (IOP), refractive errors, and endothelial cell count (ECC) over the same period. Data of 103 eyes (98 patients) were analyzed. The mean uncorrected VA was significantly improved at one month postoperatively (− 0.69 logMAR, P < 0.001), compared to the preoperative value. IOP (− 2.3 mmHg, P = 0.008) and ECC (− 333.4 cells/mm2, P = 0.027) significantly decreased one month post-surgery and remained stable thereafter. Postoperative mean spherical equivalents were similar to the prediction error throughout the follow-up period. IOP elevation (n = 8, 7.8%), cystoid macular edema (n = 4, 3.9%), and dislocation of the R-IOL (n = 10, 9.7%) were managed successfully. Overall, primary R-IOL implantation with pars plana vitrectomy is effective and safe for correcting IOL dislocation due to various causes.

Purpose: This article evaluates our experience at a retina-only private practice with small-gauge pars plana vitrectomy (PPV) for visually significant vitreous floaters. We review the surgical outcomes, complication rates, and percentage of second-eye surgery for the same indication. Methods: A retrospective, interventional case series was conducted of consecutive patients undergoing PPV for significant vitreous floaters from September 2014 to December 2018 at a high-volume vitreoretinal surgery practice. Preoperative visual acuity (VA), complication rates, and visual outcome following surgery were evaluated. Results: A total of 104 eyes in 81 patients underwent PPV for visually significant floaters; 35 (43.2%) patients had PPV in both eyes. Mean preoperative VA was 0.16 ± 0.17 logMAR (∼20/29 Snellen equivalent) and improved to 0.12 ± 0.15 logMAR (∼20/26 Snellen; Wilcoxon test, P = .008) at the last follow-up after PPV. All patients had improvement in VA at the final postoperative visit, with a VA of 20/40 or better achieved in 93.3% of cases. The complication rate of vitreous hemorrhage postoperatively was 0.96%. There were no cases of postoperative retinal tears, breaks, or endophthalmitis. Conclusions: Small-gauge PPV in the carefully selected patient is an effective and safe procedure to eliminate symptoms. VA following PPV for vitreous floaters significantly improved. Nearly half of the patients studied (43.2%) underwent PPV in the other eye.

Abstract Purpose: To report a retrospective case series of patients with chronic post operative endophthalmitis (CPE) after uneventful phacoemulsification (PKE) with intraocular lens (IOL) implantation. Methods: this study was conducted between January 2011 and June 2020, including patients with delayed-onset endopthalmitis occurring at least 2 weeks after uneventful PKE+IOL. Diagnosis was based on typical clinical features associated or not to proven sample culture. Treatment was based on step-by-step management, depending on results of microbiology and response of treatment. It consisted in first line medical treatment with a two-approach intraocular and systemic antiobiotics, followed, if necessary, by a second line conservative-IOL surgical treatment with pars plana vitrectomy (PPV), and a third line non-conservative-IOL surgical treatment with re-PPV associated to IOL explantation. Results: Seven patients were included with a mean age of 62,5 years. Mean duration interval between cataract surgery and diagnosis of CPE was 31,3 weeks. All patients presented a decrease of visual acuity with white intracapsular plaques. Only one patient had positive IOL culture. Medical treatment was sufficient in three cases. In the four other cases, PPV with IOL explantation and total capsular bag removal was conducted. Mean final BCVA was 20/160 with a gain of 4 lines and was ≥ 20/40 in 4 cases. Conclusion: The diagnosis of CPE is still challenging especially for difficulties in isolating microorganisms. It should always be considered in cases of recurrent ocular inflammation resistant to conventional treatment in operated eyes. Non-conservative IOL surgical treatment may be directly necessary in severe cases.

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.
