We experienced an atypical endophthalmitis occurring post consecutively performed in-office procedures; an intravitreal injection (IVI) of ranibizumab followed by an anterior chamber (AC) paracentesis performed twice in an eye with neovascular glaucoma (NVG). A 52-year-old diabetic male who was asymptomatic developed signs of endophthalmitis and decreased vision without pain in his left eye a few days post-IVI and AC paracentesis. The condition worsened after an initial vitreous tap and injection of antibiotics. Cultures of vitreous and aqueous samples were negative. Complete resolution occurred after a pars plana vitrectomy with IVI of antibiotics and steroid with removal of a dense “yellowish-brown” fibrinous plaque. The absence of pain, presence of a peculiar colored fibrin, mild-to-moderate vitritis without retinitis, negative cultures, and complete recovery despite the fulminant presentation; favor a diagnosis of inflammation over infection. We hypothesize that a micro-leak from a 26-gauge AC tap tract might have served as an entry port for 5% povidone-iodine from the ocular surface thus inciting inflammation. However, an exuberant inflammatory response that can be typically seen in NVG eyes after intraocular procedures cannot be excluded. Various causes of inflammation post-procedures, both toxic and nontoxic should be considered in atypical culture-negative fulminant endophthalmitis cases with good outcome posttreatment. Any minor ocular procedure may carry a risk of such complication. Patient counseling and care must be exercised in performing these procedures.

Introduction: Vitrectorhexis is an alternative for manual continuous curvilinear capsulorhexis originally developed for paediatric cataract surgery. The aim of our study was the evaluation of the technique in adult patients with penetrating ocular injury and traumatic cataracts. Methods: Eight eyes of 8 patients (23–41 years, all males) had penetrating mechanical corneal trauma. Anterior lens capsule was penetrated in all cases and additional posterior capsule defect in five cases. Intraocular foreign body was detected in one case in the crystalline lens and in two cases in the posterior segment. Standard 23G infusion cannula and vitreous cutter were applied to perform anterior capsule opening, removal of lens material, anterior vitrectomy and pars plana vitrectomy if needed. No phacoemulsification or irrigation/aspiration probe was used. Results: Vitrectorhexis could be performed in 7 out of 8 cases with the preservation of peripheral anterior capsule; primary implantation of posterior chamber intraocular lens was possible in all cases (in the bag in three eyes and into the sulcus in five eyes). Anterior chamber was stable in all cases intraoperatively, and no dropped nucleus or lens fragment loss was observed. Surgery was combined with pars plana vitrectomy in three cases, with foreign body removal (when necessary). No postoperative complication occurred. Conclusion: Vitrectorhexis was found to be an effective and safe alternative method in the management of complex anterior segment trauma cases. With its use, traditional cataract surgical devices can be substituted and additional benefits of vitreous cutter can be utilized in selected cases, especially in young adults.

Objective:  To report our experience with 27 gauge (27G) pars plana vitrectomy (PPV) system for a variety of simple to complex posterior segment disorders Methods: Single center, Retrospective, Cohort study. Data of 665 eyes of 574 patients that underwent 27G PPV for a variety of indications from July 2015 to June 2019 at a tertiary care hospital was analyzed. Results: Common surgical indications included; Diabetic tractional retinal detachment (196, 29.5%), vitreous haemorrhage (191, 28.7%), full thickness macular hole (80, 12%), epiretinal membrane (66, 9.9%), endophthalmitis (26, 3.9%), tractional diabetic macular edema (14, 2.1%), ectopia lentis (11, 1.7%), dropped lens matter (13, 2%) and others (68, 10.2%). Mean operating time was 62 ± 37 minutes. With the exception of 2 cases where 20G fragmatome was utilized, no case required conversion to 20 gauge system while a 25G trocar was used for the silicon oil injection. Per-operative complications included; iatrogenic retinal tear (2 eyes, 0.3%) and supra choroidal silicon oil migration (1 eye, 0.15%). Post-operative complications were raised IOP (7 eyes, 1%), endophthalmitis (1 eye, 0.15%), hemorrhagic occlusive retinal vasculitis (1 eye, 0.15%) and retinal detachment (2 eyes, 0.3%). Mean Visual Acuity improved from 1.62 ± 0.68 logarithm of minimum angle of resolution (logMAR) to 0.4 ± 0.38 logMAR (P <0.001). Conclusion: With 3 months follow up time, 27 G PPV has proved to be a safe and effective system for both simpler and complex retinal pathologies requiring significant surgical manipulation.

AbstractA 57-year-old otherwise healthy male presented to our department seven days following uneventful pars-plana vitrectomy with gas tamponade for a superior bullous retinal detachment in the left eye. Ophthalmic examination revealed anterior segment inflammation with hypopyon and fibrinous exudate. Intra-ocular pressure was 28 mmHg. Posterior segment evaluation was difficult to assess due to the presence of anterior capsule opacification and gas bubble. A Toxic Anterior Segment Syndrome was suspected, and the patient was treated with topical and oral corticosteroid medication in combination with anti-glaucomatous therapy. On follow-up, anterior segment inflammation and ocular hypertension improved. On day ten post-operatively, ocular ultrasonography demonstrated lens material inferiorly with attached retina. The final diagnosis of posterior lens nucleus dislocation with lens-induced uveitis was retained. The patient underwent an uneventful second vitrectomy with aspiration of the dislocated lens nucleus and sulcus three piece-lens implantation. On last follow-up, visual acuity was 20/50 with no relapsing of ocular inflammation and the retina remained reattached.
