Abstract Background: There is an increasing trend toward performing pars plana vitrectomy and simultaneous cataract extraction in the management of patients with intraocular foreign bodies and traumatic cataracts. Herein, we describe a case of good visual rehabilitation in a patient without traumatic cataract surgery after removal of a ferrous intravitreal foreign body (IVFB) using an external approach. Case presentation: A 44-year-old man presented to our ophthalmology department because of decreased visual acuity after a penetrating trauma to the left eye 2 days earlier. Best-corrected visual acuity (BCVA) was 20/200. An examination revealed a midperipheral self-sealing corneal penetrating wound at the 5 o’clock position, in addition to a mild inflammatory reaction in the anterior chamber. Pupil dilation revealed peripheral anterior and posterior capsular violations, with subcapsular opacity involving the visual axis. A small metallic-like foreign body suspended in the vitreous was confirmed by B-scan ultrasonography and orbital computed tomography. This IVFB was successfully removed by external magnetic extraction through a pars plana incision. At the 2-week follow-up, the traumatic cataract was partially resolved, and BCVA improved to 20/125. At the 3-month follow-up, the traumatic cataract was mostly resolved, the visual axis was clear under a normal pupil, and BCVA improved to 20/20. Peripheral localized lens opacity was found after pupil dilation, and a fundus examination revealed no obvious abnormality. Conclusions: The size and location of an intraocular foreign body and the location and extent of lenticular involvement and associated injuries should be considered in patients with intraocular foreign bodies and traumatic cataracts. In selected patients with a small ferrous IVFB and a localized traumatic cataract, a good visual outcome may be achieved with minimal surgery.

Purpose. To investigate transvitreal intraocular foreign body (IOFB) removal results, and to determine indications for this splinter removal approach. Materials and methods. A chart analysis of 35 cases with splinter eye trauma was carried out. In all patients, a pars plana vitreoretinal surgical procedure was performed to remove the IOFB. Results. The intraocular penetration of foreign body was accompanied by injuries of different eyeball structures, which presented as intravitreal hemorrhage, hyphema, subretinal bleeding, retinal detachment, traumatic cataract, iridocyclitis. Splitter removal was complemented by endolaser coagulation; scleroplastic component and gaz-fluid exchange. In 54.29% patients with trauma, a lensectomy had to be added to the vitrectomy with IOFB removal. As a result of treatment, visual acuity increased in 51.43% injured patients. In the late post-operative period, retinal detachment developed in 14.29% of cases. Conclusions. IOFB removal by transvitreal approach is recommended in intravitreal, pre- or intraretinal splitter position; in retro-equatorial foreign body localization; when intraoperative splitter visualization is possible; in posterior vitreous detachment formation.

Introduction. Penetrating injury is characterized by the existence of entry wound only, and it can be with or without an intraocular foreign body (IOFB). IOFB can lead to a mechanical injury of the eye and to cause infection or to manifest other toxic effects on intraocular structures. Iron and copper can dissolve and cause siderosis, i.e. chalcosis of the eye. Ocular siderosis is diagnosed by clinical and electroretinogram (ERG) findings. Outline of Cases. The first patient was a 37?year?old male who was injured by a metal foreign body. He presented at the Clinic two years after the injury. Visual acuity of the right eye (VOD) on admission was VOD=L+P+ (light projection). Pars plana phacovitrectomy with IOFB extraction was done. Visual acuity on discharge was VOD=3/60 cc + 7.50 Dsph=0.2. The second patient was a 55?year?old male who presented at the clinic 18 months after injury. On admission visual acuity in his left eye was VOS 1/60. Pars plana phacovitrectomy with IOFB extraction was done. Visual acuity on discharge was VOS=0.7 through the stenopeic slit. Conclusion. In penetrating injuries caused by a metal IOFB pars plana vitrectomy with IOFB extraction is indicated. In cases with IOFB, when visual acuity is preserved, the lens is transparent, while the eye is without signs of infection, urgent pars plana vitrectomy is not necessary. Such patients need regular follow?up with obligatory ERG findings.

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.

Introduction. We present a patient with perforative eye injury, a metal foreign body in the lens and traumatic cataract. The paper emphasises the importance of phacoemulsification in case of patients with a traumatic cataract and the presence of a metal foreign body. Case Outline. A 41-year-old patient had a perforative wound of the cornea caused by a metal foreign body that also perforated the anterior lens capsule and remained in the paracentral anterior part of the lens. The injury, which happened upon hitting of a hammer against a metal object, showed the presence of a tangential wound of the cornea adapted edges, and a formed anterior eye chamber. The presence of a metal spear-shaped foreign body was partly inside the anterior eye chamber and partly in the central area of the lens. The visual acuity of the injured eye was 0.2. The technique of removing the foreign body out of the lens and the phacoemulsification of the lens with the implantation of intraocular lens is presented. The paracentral wound on the cornea was not sutured because of well-adapted edges. On the first postoperative day there were no inflammatory signs, and best uncorrected visual acuity of 0.8. Conclusion. Posttraumatic cataracts with a metal foreign body in the lens require operative treatment in order to remove the foreign body, phacoemulsification and implantation of artificial lens. Because of anterior capsule lesion, special care should be taken in regard to anterior capsulorhexis and appropriate hydrodisection. Ocular hypotonia and possible damage of the posterior capsule in some cases can make phacoemulsification more difficult to perform.

Purpose: This work evaluates the role of combined phacoemulsification and vitrectomy surgery in the management of cataract associated with noninfectious uveitis. Methods: A retrospective chart review was conducted of all patients aged 7 years or older who underwent a combined surgical approach from 2005 to 2018. Results: Eighty-five eyes of 67 patients were included in the study; 10.7% of eyes had a best-corrected visual acuity (BCVA) of 20/40 or better at time of surgery. At 1-year follow-up, 63.4% of eyes had a BCVA 20/40 or better and 7.6% had a BCVA of 20/200 or worse. There was an overall decrease in cystoid macular edema after surgery compared with preoperatively (47.6% vs 34.5% presurgery and postsurgery, respectively). Complete inflammatory disease remission off immunomodulatory therapy and systemic steroids was achieved in 21.1% of patients. Conclusions: A combined surgical approach is effective in visual rehabilitation in patients with uveitic cataracts and may promote inflammatory disease remission specifically in intermediate uveitis.
