Purpose: Hydroxychloroquine (HCQ) is an important medication for patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and other rheumatic diseases. Although it is well-tolerated and cost-effective, the risk of HCQ retinal toxicity is of increasing concern. The aim of this study is to re-examine the HCQ retinal toxicity incidence rate, risk factors and clinical course after discontinuation.

Purpose: To evaluate the efficacy and safety of early pars plana vitrectomy (PPV) for the treatment of acute infective endophthalmitis, and identify prognostic factors for better visual outcome.
Design: Retrospective cohort study.
Methods: Consecutive patients who underwent early PPV within 72 hours of presentation for the treatment of acute infective bacterial endophthalmitis and presented to a large tertiary referral center in New South Wales, Australia, between January 2009 and December 2013 were included.
Purpose: To determine if a new, single-sample device (ESwab; Copan Diagnostics, Inc) can simplify the traditional multi-sample approach to specimen collection in infectious keratitis.
Design: Prospective, diagnostic test evaluation.
Methods: In this institutional study, patients with suspected infectious keratitis meeting traditional criteria for diagnostic corneal specimen collection and culture were randomized to the order of first specimen collection method: ESwab or a sample directly plated for growth on chocolate agar.
Purpose: To evaluate the effects and safety of travel by land through high mountainous elevations after surgery in patients who have undergone pars plana vitrectomy with intraocular gas.
Methods: A retrospective cohort study of 75 patients post pars plana vitrectomy with intraocular gas who traveled by land through mountain elevations of up to 3895 feet above sea level within 1 day of surgery.
Results: The average rate of ascent through the mountains was 29 ft/min and the maximum theoretical ocular compensation was 0.
Objectives: To determine the incidence and clinical and cytologic diagnostic accuracy of vitreoretinal lymphoma (VRL) and to evaluate its clinical features, management, and outcomes in a cohort of patients who underwent diagnostic vitrectomy.
Methods: Retrospective medical record review of 463 diagnostic vitrectomy specimens from 430 patients collected from October 1, 1990, through December 31, 2010, from Vancouver General Hospital and the British Columbia Cancer Agency.
Results: A total of 22 patients were diagnosed as having VRL with a preoperative clinical diagnostic sensitivity of 77%, specificity of 73%, positive predictive value of 13%, and negative predictive value of 98%.
Purpose: The purpose of this study was to report a case of multifocal serous neurosensory retinal detachments associated with systemic differentiation syndrome (DS) (formerly known as all-trans retinoic acid [ATRA] syndrome) in a patient with acute promyelocytic leukemia.
Methods: In this observational case report, we identify a case of DS because of ATRA induction therapy with associated multiple focal serous neurosensory retinal detachments in a 39-year-old man with acute promyelocytic leukemia.
Results: While suffering from a rebound episode of DS secondary to ATRA therapy, the patient experienced deterioration of his vision bilaterally.
Purpose: To evaluate the effectiveness and safety of the heavy silicone oil Densiron-68 as an internal retinal tamponade after vitrectomy in patients with primary inferior rhegmatogenous retinal detachment.
Methods: A retrospective consecutive case series involving inferior rhegmatogenous retinal detachment in 42 patients recruited between 2007 and 2010 was completed. All patients underwent primary vitrectomy followed by injection of Densiron-68.
