Vitrectomy methotrexate

BACKGROUND: Intraocular lymphoma accounts for fewer than 1% of intraocular tumors. When the posterior segment is involved, it can be further classified as vitreoretinal or choroidal lymphoma. Vitreoretinal lymphoma (VRL) can rarely masquerade as an infectious retinitis making diagnosis and management challenging. RESULTS: A 73-year-old woman with a history of non-central nervous system (CNS) involving diffuse large B-cell lymphoma (DLBCL) was referred for worsening blurry vision-visual acuity of count figures at 2 ft-in her right eye for 8 months...

PURPOSE: To describe the ocular clinical features, histopathological findings, and treatment outcomes of lymphomas involving the ciliary body. METHODS: We demonstrate three cases of ciliary body involvement by lymphoma from 2013 to 2019 in Peking Union Medical College Hospital (PUMCH). All patients underwent examinations including best corrected visual acuity (BCVA), slit-lamp microscopy, indirect ophthalmoscope, ultrasound biomicroscopy (UBM), and diagnostic vitrectomy...

Objective The objective of this pilot study was to evaluate the efficacy and safety of per-operative intravitreal methotrexate (MTX) infusion during vitrectomy in patients of retinal detachment (RD) with advanced grade proliferative vitreoretinopathy (PVR). Methods In this prospective interventional case series, we included patients with Grade C PVR, recurrent RD, and open globe trauma. All patients underwent standard single surgeon operated 23-gauge pars plana vitrectomy (PPV) with 80mg of MTX in 1000mL of irrigation fluid...

PURPOSE: Post-transplant lymphoproliferative disorder (PTLD) represents a spectrum of disorders associated with Epstein Barr Virus infection in up to 80% of cases in the setting of pharmacologic immunosuppression following hematopoietic stem cell or solid organ transplantation. Ocular involvement is a rare finding in PTLD. OBSERVATION: We report the case of a 38-year-old man who presented with unilateral retinal infiltrates as first manifestation of PTLD relapse...

PURPOSE: To assess the anatomical and functional outcomes of intravitreal infusion of methotrexate (MTX) during pars plana vitrectomy (PPV) for proliferative vitreoretinopathy (PVR) associated with rhegmatogenous retinal detachment (RRD). METHODS: Comparative interventional nonrandomized study including consecutive patients who had vitrectomy for RRD. The study included six groups. Groups I (established PVR), II (high risk of PVR), and III (no risk of PVR) comprised prospectively recruited study eyes, which received PPV and adjuvant intravitreal MTX infusion equivalent to 400  μ g/0...

PURPOSE: The purpose of this study was to evaluate the corneal toxicity of intravitreal methotrexate used for the prevention of proliferative vitreoretinopathy (PVR). METHODS: In this retrospective case series, eyes with recurrent retinal detachment secondary to PVR were treated with intravitreal injections of 400 μg methotrexate at an average frequency of every 7 days after vitrectomy with silicone oil tamponade. Corneas were examined for corneal epitheliopathy by slit-lamp biomicroscopy before each injection...

We describe the electroretinographic findings of a case of primary intraocular lymphoma (PIOL) wherein the patient received intravitreal injections of methotrexate (ivMTX). A 62-year-old man developed blurred vision and complained of decreased visual acuity (VA) in his right eye. Fundus examination showed vitreous opacity and multiple subretinal yellowish lesions. Optical coherence tomography (OCT) revealed subretinal and intraretinal infiltrations. The full-field electroretinogram (ffERG) showed subnormal combined rod-cone response and multifocal electroretinogram (mfERG) recorded using skin electrodes showed severe attenuation of the response compared with the other eye...

AIM: To investigate the clinical manifestations, diagnostic approaches, treatments, and outcomes of intraocular lymphoma. METHODS: In this retrospective study, 16 patients (28 eyes) with intraocular lymphoma were recruited in the Department of Ophthalmology, Peking Union Medical College Hospital, from 2004 to 2019. All patients underwent comprehensive ophthalmic examinations. Vitreous specimens of 13 patients were sent for cytopathology examination and other adjunctive diagnostic procedures...

While innovations in the surgical management of retinal detachment (RD) with proliferative vitreoretinopathy (PVR) have significantly improved anatomic and visual outcomes over the years, recurrent RD due to PVR remains the major limitation to success. There are currently no medical therapies proven to be effective against PVR in humans. Increased understanding of the pathophysiology and risk factors for PVR have helped guide investigations for molecular targets. Drugs that counteract inflammation, proliferation, and growth factors are the leading candidates for treatment of PVR...

A 69-year-old female presented with right vitreous cells and cystoid macular oedema (CMO). One year previously, she had received two cycles of attenuated methotrexate-based chemotherapy for primary central nervous system (CNS) lymphoma, abandoned due to toxicity. There was no past ocular history of note aside from mild cataract. Due to her history of previous CNS lymphoma, we suspected vitreoretinal lymphoma (VRL), but the presence of the CMO made this unlikely. She underwent a diagnostic vitrectomy. Histology and immunohistochemistry showed the presence of a high-grade B-cell VRL...

A 64-year-old Caucasian woman was referred to our hospital after referring vision loss; she had been previously diagnosed with systemic diffuse large B-cell lymphoma. Retinal and optic nerve involvement were found in her right eye, and iris and vitreous involvement were found in her left eye. Vitreoretinal lymphomas (VRL) are rare in medical literature, hence there is a lack of standardised studies regarding therapeutic options in these patients. In our patient, we decided to add intravitreal injections of rituximab and methotrexate to systemic chemotherapy, and to perform pars plana vitrectomy...

Juvenile idiopathic arthritis-associated uveitis is rare in the Japanese population. In this article, we report a child whose macular edema was controlled for years after cataract surgery with adalimumab, and reviewed 26 Japanese patients in the literature. In this case report, a 4-year-old boy developed band keratopathy, posterior iris synechiae, and complicated cataract in both eyes. Oral prednisolone prescribed at another hospital was discontinued due to high intraocular pressure in both eyes as a steroid responder...

BACKGROUND: Intravitreal methotrexate has been proven to be an effective treatment method for vitreoretinal lymphoma. However, keratopathy occurs as the major side effect during treatment in most cases. The purpose of this study is to describe the characteristics of primary central nervous system lymphoma (PCNSL) with intraocular involvement and to attempt to reduce the incidence of keratopathy caused by intravitreal methotrexate. METHODS: The medical records of 22 PCNSL patients with intraocular involvement (33 eyes) were reviewed...

Purpose: To highlight the surgical and medical management used in an extensive globe penetrating injury caused by an acupuncture needle. Observations: We report on a case of acupuncture treatment error resulting in needle penetration of the eye, retinal detachment, and progressive post-traumatic proliferative vitreoretinopathy (PVR). This patient required aggressive surgical management with multiple vitrectomies along with adjunctive intravitreal methotrexate to control ongoing PVR...

PURPOSE: To study and compare the efficacy of different therapeutic options for the treatment of central serous chorioretinopathy (CSCR). METHODS: This is a nonrandomized, international multicentre study on 1719 patients (1861 eyes) diagnosed with CSCR, from 63 centres (24 countries). Reported data included different methods of treatment and both results of diagnostic examinations [fluorescein angiography and/or optical coherent tomography (OCT)] and best-corrected visual acuity (BCVA) before and after therapy...

Background: Primary vitreoretinal lymphoma (VRL) is a rare disease with 30-380 new cases in the United States per year. Its insidious process and spread to the central nervous system (CNS) leads to a mean 5-year survival rate from 41.4 to 71%. Medical treatment of VRL has been summarized extensively in the literature and involves intraocular rituximab and methotrexate as first line agents in unilateral VRL, with systemic chemotherapy to be considered in bilateral or CNS-involving disease...

BACKGROUND/OBJECTIVES: To evaluate retinal lymphoma treatment at the University of California San Francisco. SUBJECTS/METHODS: Prospective observational audit. Patients were treated systemically, usually with: methotrexate, temozolomide, and rituximab induction; etoposide consolidation; and maintenance with lenalidomide or another immunomodulatory agent. Persistent disease was treated initially by ocular radiotherapy or intravitreal melphalan and latterly by vitrectomy...

PURPOSE: To evaluate the effects of repeated intra-silicone oil (SO) injections of methotrexate (MTX) on the outcomes of surgery for rhegmatogenous retinal detachment (RRD) with grade C proliferative vitreoretinopathy (PVR-C). METHODS: In this prospective pilot case series, eyes with RRD and PVR-C underwent pars plana vitrectomy and intraocular injection of SO. At the conclusion of the procedure, 250 µg of MTX was injected into the SO-filled vitreous cavity. Intra-SO injection was repeated at weeks 3 and 6; the minimum follow-up period was 6 months...

Purpose : To evaluate the role of intrasilicone oil injection of methotrexate (MTX) at the end of vitrectomy surgery for rhegmatogenous retinal detachment (RRD) associated with proliferative vitreoretinopathy (PVR). Methods : In this prospective comparative study, pars plana vitrectomy and retinal reattachment were performed for eyes with RRD with grade C PVR. In the MTX group, 250 µg MTX was injected into the silicone oil at the end of surgery. The rate of retinal redetachment associated with PVR was assessed...

PURPOSE: Posterior scleritis is the least frequent form of scleritis accounting for around 2%-8% of all scleritis cases. We aim to present the 6-year clinical course of a 62-year-old female patient with bilateral progressive necrotizing posterior scleritis who suffered from concurrent active psoriasis and psoriatic arthritis. METHODS: Descriptive case report. RESULTS: A middle-aged female patient was referred to our clinic because of left eye peripheral progressively enlarging white retinochoroidal lesions...
