Purpose: To compare the visual outcome in patients of nucleus drop undergoing same day pars plana vitrectomy (PPV) versus delayed PPV. Methods: A prospective observational study was conducted on 50 eyes with posteriorly dislocated nucleus after cataract surgery who underwent PPV. Study variables included the time duration between nucleus drop and PPV, nal best-corrected visual acuity(BCVA), and complications after PPV. In 7(14%) eyes, PPV was performed on the same day of cataract surgery and in 43(86%) eyes, an elective PPV was performed after 1 week of cataract surgery. All our cases had intraocular lens(IOL) implanted at the end of PPV. Patients were followed up for 6 months with BCVA, intraocular pressure (IOP) measurement, indirect ophthalmoscopy and ocular coherence tomography(OCT).Results: Comparison was made between VA in patients who underwent PPV on same day (n=7) and those who underwent delayed PPV (n=43). In the same day group, 85.71% patients had BCVA ranged between 6/6 to 6/18, while only 14.29% had BCVA between 6/18 to 6/60 at the nal follow up. In the delayed PPV group , 60.47% had BCVA range between 6/6 to 6/18, 27.90% had BCVA ranged between 6/18 to 6/60 and only 11.63% patients had BCVA of <6/60- hand movements (HM) . Pvalue was 0.398 which was not statistically signicant.Conclusion: Majority of the patients obtain good VAafter PPVfor nucleus drop irrespective of the time. The visual outcome in both the groups was comparable, but slightly better results were obtained in the same day PPVgroup.

This report describes the first case of an ocular infection induced by Purpureocillium lilacinum in Poland. The patient was a 51-year-old immunocompetent contact lens user who suffered from subacute keratitis and progressive granulomatous uveitis. He underwent penetrating keratoplasty for corneal perforation, followed by cataract surgery due to rapid uveitic cataract. A few weeks later, intraocular lens removal and pars plana vitrectomy were necessary due to endophthalmitis. The patient was treated with topical, systemic, and intravitreal voriconazole with improvement; however, the visual outcome was poor. The pathogen was identified by MALDI-TOF MS.

Purpose is to review the pathogenic mechanism for ocular hypertension and glaucoma development after pars plana vitrectomy. Both acute and chronic causes are considered, and special attention is paid to the theories and clinical evidence on the risk of developing Open Angle Glaucoma (OAG) after Pars Plana Vitrectomy (PPV). Most existing scientific literature on the issue agree on the role of ascorbate as an oxygen scavenger within the vitreous chamber. Oxygen tension in the vitreous and anterior chamber is maximum inn proximity of the retinal surface and endothelium, respectively and steeply decreases toward the lens, on both sides, and trabecular meshwork. Vitreous removal and, to a lesser extent, liquefaction, greatly reduces oxygen tension gradient in vitreous chamber while cataract extraction has similar effects on anterior chamber oxygen gradients. Oxygen derivatives originated from the cornea and retina are actively reduced by the vitreous gel and/or the crystalline lens. Vitreous removal and cataract extraction reduce drastically this function. Most reported clinical series confirm this hypothesis although protocol difference and follow-up length greatly impact the reliability of results.

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.

Background: Endophthalmitis is one of the emergencies in ophthalmology and can cause blindness. The most common cause of endophthalmitis in intraocular surgery is cataract surgery. Immediate diagnosis and treatment can provide optimal final vision. This research aimed to describe the demographic data, and causative microorganisms, as well as the success rate of visual outcome after pars plana vitrectomy (PPV) in post-cataract surgery endophthalmitis in Cipto Mangunkusumo Hospital. Methods: A retrospective descriptive study of post-cataract surgery endophthalmitis underwent vitrectomy in Cipto Mangunkusumo Hospital, Indonesia, from January 2017 - June 2017. Results: There were twenty one cases of post-cataract surgery endophthalmitis undergoes PPV within the period of January 2017-June 2017. The most frequently identified causative microorganism was Staphylococcus (23%). There was an improvement of visual acuity after PPV procedure in 47,6% post-cataract surgery endophthalmitis. Conclusion: Immediate PPV is an effective treatment and leads to vision improvement in post-cataract surgery endophthalmitis.   Keywords: pars plana vitrectomy, endophthalmitis, cataract surgery

Purpose. To compare different methods of lens removal during vitreous surgery. Methods. We reviewed the data of 37 consecutive eye operations with combined surgery of the lens and vitreous in the Mülheim Eye Hospital between March ‘93 and September ‘94. Results. In 14 eyes a pars plana lensectomy was done, in 7 an ECCE (extra capsular cataract extraction), and in 16 phacoemulsification was combined with a regular threeport pars plana vitrectomy. Conclusions. The choice of procedure was mainly influenced by the hardness of the lens and whether an IOL implant was considered. If no IOL is planned and the lens is soft enough, the best way to remove it is by pars plana lensectomy. If the nucleus seems too hard, phacoemulsification should be performed, because of the risk of releasing the nucleus into the posterior segment. If an IOL is planned, the best method of lens removal is phacoemulsification via a scleral tunnel. In both cases if the nucleus is very hard ECCE should be performed because of the risk of corneal edema.

Purpose: To describe a case with an unusual presentation of Propionibacterium acnes ( P acnes) with ultimately a good visual outcome. Methods: A case report with review of approaches to P acnes endophthalmitis. Results: We describe a patient with an unusual presentation of P acnes of panuveitis with white, circular preretinal lesions without intracapsular deposits. Diagnosis was made from cultures from pars plana vitrectomy. Eventually, she was definitively managed with capsulectomy, repositioning of her intraocular lens via sutureless intrascleral fixation, and intravitreal vancomycin injection. Conclusion: This is a report of P acnes endophthalmitis presenting with discrete preretinal lesions where surgical and medical management lead to a complete resolution of uveitis and symptoms after a 3-year follow up where the patient’s final visual acuity was Snellen 20/20 OU.
