Purpose: To describe the clinical history and histopathologic findings of 2 cases of retinoinvasive uveal melanoma. Methods: The medical records and pathology specimens of 2 patients with retinoinvasive uveal melanoma were reviewed. Results: The first patient had an iris/ciliary body melanoma that was treated and the second patient had suspected iridocorneal endothelial syndrome. Both patients developed a blind, painful eye; the first patient's right eye was enucleated and the left eye of the second patient underwent evisceration...

Background and purpose The purpose of this article is to estimate the distribution of superselective intra-arterial chemotherapy (IAC) delivery to ocular target tissue using quantitative digital subtraction angiography (qDSA). Materials and methods From March 2010 to January 2016, 50 ophthalmic artery contrast DSAs obtained immediately prior to IAC infusions in 22 patients were analyzed. This study was conducted under a retrospective review IRB (no. 10-01862). Parametric color-coded DSAs (iFlow, Siemens Medical) were post-processed (MATLAB, The Mathworks Inc...

METHODS: Patients with stage IV metastatic melanoma and BRAF V600E mutations (n = 11, 31-68 years of age) were included. Treatment was with oral dabrafenib, 150 mg bid, trametinib, 2 mg/day, and HCQ, 400 mg to 600 mg bid.

REVIEW
Milton Packer
A primary goal of the treatment of type 2 mellitus is the prevention of morbidity and mortality due to cardiovascular disease. However, antihyperglycemic drugs have the capacity to cause deleterious effects on the circulation, a risk that is not adequately reflected by the endpoints selected for emphasis in large-scale clinical trials that are designed to evaluate cardiovascular safety. The primary endpoint of the large-scale studies mandated by regulatory authorities focuses only on 3-4 events that depict only a limited view of the circulatory system...

Importance: Anti-vascular endothelial growth factor (VEGF) therapies are a novel treatment option in retinopathy of prematurity (ROP). Data on dosing, efficacy, and safety are insufficient. Objective: To investigate lower doses of anti-VEGF therapy with ranibizumab, a substance with a significantly shorter systemic half-life than the standard treatment, bevacizumab. Design, Setting, and Participants: This randomized, multicenter, double-blind, investigator-initiated trial at 9 academic medical centers in Germany compared ranibizumab doses of 0...

BACKGROUND: The increasing incidence of medical retinal diseases has created capacity issues across UK. In this study, we describe the implementation and outcomes of virtual medical retina clinics (VMRCs) at Moorfields Eye Hospital, South Division, London. It represents a promising solution to ensure that patients are seen and treated in a timely fashion METHODS: First attendances in the VMRC (September 2016-May 2017) were included. It was open to non-urgent external referrals and to existing patients in a face-to-face clinic (F2FC)...

A 58-year-old man with end-stage retinitis pigmentosa (RP) and visual acuity of light perception in both eyes received simultaneous phacoemulsification with intraocular lens implantation and implantation of the Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA) to his right eye 1 year ago. He accomplished the fitting and rehabilitation sessions, and no extraocular or intraocular complications were encountered perioperatively, postoperatively, or during the follow-up. The patient used the prosthesis actively for 2...

BACKGROUND AND OBJECTIVE: Previous literature assessing ocular hemorrhagic complications of anticoagulant/antiplatelet medications in routine clinical practice is limited. This study evaluates the prevalence of spontaneous ocular hemorrhagic events associated with anticoagulation/antiplatelet therapy. PATIENTS AND METHODS: A retrospective study was performed to identify patients taking anticoagulants (rivaroxaban [Xarelto; Janssen Pharmaceuticals, Beerse, Belgium], bivalirudin [Angiomax; The Medicines Company, Parsippany, NJ], lepirudin [Refludan; Bayer HealthCare Pharmaceuticals, Berlin, Germany], dabigatran [Pradaxa; Boehringer Ingelheim, Ingelheim am Rhein, Germany], and argatroban) and antiplatelet agents (clopidogrel [Plavix; Bristol-Myers Squibb, New York City, NY], prasugrel [Effient; Lilly Medical, Indianapolis, IN], and ticagrelor [Brilinta; AstraZeneca, Cambridge, UK]) who presented for an eye examination...

The advent of intravitreal anti-vascular endothelial growth factor (anti-VEGF) medications has revolutionized the treatment of diabetic eye diseases. Herein, we report the outcomes of clinical studies carried out by the Pan-American Collaborative Retina Study Group (PACORES), with a specific focus on the efficacy of intravitreal bevacizumab in the management of diabetic macular edema and proliferative diabetic retinopathy. We will also discuss the use of intravitreal bevacizumab as a preoperative, adjuvant therapy before vitrectomy for proliferative diabetic retinopathy...

Endogenous fungal endophthalmitis (EFE) caused by disseminated fusariosis is a rare condition that generally has a poor outcome, even with intensive therapy. Here, we describe a case in which this type of EFE was diagnosed with vitreous sampling and was successfully treated with 25-gauge vitrectomy and antifungals, including liposomal amphotericin B and voriconazole. A 16-year-old male patient undergoing treatment for acute myeloid leukemia complained of eye pain and blurred vision in his right eye. Treatment was initiated for a vitreous opacity, possibly associated with herpetic retinitis, but the patient worsened and he was referred to us...

BACKGROUND: Prior optical coherence tomography (OCT) studies of schizophrenia have identified thinning of retinal layers. However, findings have varied across reports, and most studies have had serious methodological limitations. To address unresolved issues, we determined whether: (1) retinal thinning in schizophrenia occurs independently of comorbid medical conditions that affect the retina; (2) thinning is independent of antipsychotic medication dose; (3) optic nerve parameters are abnormal in schizophrenia; and (4) OCT indices are related to visual and cognitive impairments common in schizophrenia...

PURPOSE: To report the outcome of scleral buckling using a non-contact wide-angle viewing system with a 25-gauge chandelier endoilluminator. METHODS: Retrospective analyses of medical records were performed for 17 eyes of 16 patients with primary rhegmatogenous retinal detachment (RRD) without proliferative vitreoretinopathy who had undergone conventional scleral buckling with cryoretinopexy using the combination of a non-contact wide-angle viewing system and chandelier endoillumination...

Introduction: Retinoblastoma is a primary malignant intraocular neoplasm that arise from immature retinoblasts with in developing retina. The commonest presenting sign in developing country is proptosis which is the late presenting sign. We report presenting signs of retinoblastoma in Ethiopian children seen at a tertiary level teaching hospitals in Ethiopia. Methods: Prospective case series study was done on children who presented with retinoblastoma between May 1, 2005 and September 1, 2006...

PURPOSE: To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. METHODS: Case report. RESULTS: Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year...
