PURPOSE: Hydroxychloroquine (HCQ), the analog of chloroquine, augments the effect of chemotherapies and radiotherapy on various tumors identified in the current clinical trials. Meanwhile, the toxicity of HCQ retinopathy raises concern worldwide. Thus, the potent autophagy inhibitors are urgently needed. METHODS: A systematic review was related to 'hydroxychloroquine' or 'chloroquine' with 'clinical trials,' 'retinopathy' and 'new autophagy inhibitors.' This led to many cross-references involving HCQ, and these data have been incorporated into the following study...

OBJECTIVE: To study the incidences of and risk factors for chloroquine (CQ) and hydroxychloroquine (HCQ) retinopathy in Thai rheumatologic patients. METHODS: A retrospective cohort study of 234 rheumatologic patients receiving either CQ or HCQ was conducted. Patients were divided based on whether or not they developed retinopathy as retinopathy-positive or negative groups. Medical records giving details regarding age, gender, body weight, underlying diseases, daily doses, and cumulative doses of CQ or HCQ were reviewed...

PURPOSE: To quantify external limiting membrane (ELM) disruption and photoreceptor volume over time, using spectral domain optical coherence tomography in eyes with hydroxychloroquine (HCQ) toxic effects after discontinuation. METHODS: We performed a retrospective chart review of patients who were screened for toxic effects of HCQ between January 1, 2009 and August 31, 2014, and identified 10 patients diagnosed as having HCQ retinal toxic effects. Intact ELM and the Bruch membrane were manually traced using ImageJ software and their lengths from each scan of the spectral domain optical coherence tomography macular volume were summed...

PURPOSE: To report a case of bilateral panretinal degeneration in a patient with long-term hydroxychloroquine exposure and positive for a heterozygous mutation in the USH2A gene. METHODS: Retrospective case report. Multimodal imaging including spectral-domain optical coherence tomography, fundus autofluorescence, and fluorescein angiography was performed and the results are presented.

BACKGROUND: Throughout medicine, the cost of various treatments has been increasingly studied with the result that certain management guidelines might be reevaluated in their context. Cost-utility is a term referring to the expense of preventing the loss of quality of life, quantified in dollars per quality-adjusted life year. In 2002, the American Academy of Ophthalmology published hydroxychloroquine screening recommendations which were revised in 2011. The purpose of this report is to estimate the cost-utility of these recommendations...

The American Academy of Ophthalmology published in 2011 revised recommendations regarding screening for hydroxychloroquine (HCQ) toxicity. We aimed to assess implementation of these recommendations by rheumatologists and ophthalmologists. A questionnaire regarding screening practices for HCQ toxicity was distributed among all members of the Israeli societies of Rheumatology and Ophthalmology. A total of 128 physicians responded to the questionnaire (rheumatologists: 60, ophthalmologists: 68). Only 5% of the rheumatologists and 15% of the ophthalmologists are aware of ophthalmologic assessments recommended for baseline and follow-up evaluation...

Maria Dettoraki, Marilita M Moschos
Multifocal electroretinography (mfERG) is an objective, noninvasive examination for the assessment of visual function. It enables the stimulation of multiple retinal areas simultaneously and recording of each response independently, providing a topographic measure of retinal electrophysiological activity in the central 40-50° of the retina. A clinical application of mfERG represents the assessment of retinal toxicity associated with systemic medications. Drug-induced retinopathy represents a disease that, although not common, requires early recognition: if not detected early, it may progress and cause irreversible retinal dysfunction with subsequent visual impairment...

PURPOSE: To compare retinal layer volumes using spectral-domain optical coherence tomography between eyes with hydroxychloroquine (HCQ) toxicity and control eyes. METHODS: Using a previously validated algorithm, volumetric analysis from the macular cube scan of the ganglion cell layer, inner plexiform layer, inner nuclear layer, and outer retina (outer plexiform layer to retinal pigment epithelium) layers were compared in three sets of patients: patients with a clinical diagnosis of HCQ toxicity, age-matched patients taking HCQ but not manifesting overt toxicity, and age-matched control patients...

Retina is the part of the eye suffering most damage from pharmaceutical molecules. Drug-induced retinopathies have been described but data are scarce and sometimes conflicting especially concerning its potential seriousness. The aim of this study was to investigate potential associations between drugs and retinal disorders using the French Pharmacovigilance data. We used the case/non-case method in the French PharmacoVigilance Database (FPVD) to identify drugs able to induce retinopathies. Cases were reports of retinal disorders in the FPVD between January 2008 and December 2012...

REVIEW
Hephzibah Akpovwa
Viruses from the Filoviridae family, as many other virus families, require an acidic pH for successful infection and are therefore susceptible to the actions of 4-aminoquinolines, such as chloroquine. Although the mechanisms of action of chloroquine clearly indicate that it might inhibit filoviral infections, several clinical trials that attempted to use chloroquine in the treatment of other acute viral infections - including dengue and influenza A and B - caused by low pH-dependent viruses, have reported that chloroquine had no clinical efficacy, and these results demoted chloroquine from the potential treatments for other virus families requiring low pH for infectivity...

BACKGROUND: The American Academy of Ophthalmology recommendations on screening for chloroquine (CQ) and hydroxychloroquine (HCQ) retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. PATTERN OF RETINOPATHY: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. DOSE: We recommend a maximum daily HCQ use of ≤5...

Importance: Retinopathy is a known risk of long-term use of hydroxychloroquine sulfate. However, whether the inner as well as outer retina are involved before retinopathy develops and whether changes in the retina might signal impending toxic effects during screening remain unknown. Objective: To determine the degree of inner and outer retinal involvement in short- and long-term use of hydroxychloroquine before the development of retinopathy. Design, Setting, and Participants: This retrospective medical record review of spectral-domain optical coherence tomography (SD-OCT) findings was performed at an academic medical center...

Hydroxychloroquine (HCQ) is an antimalarial drug used extensively in treatment of autoimmune diseases such as rheumatoid arthritis. Retinal toxicity is the most important side effects of this drug. Even after the drug is discontinued, retinal degeneration from HCQ can continue to progress. Consequently, multiple ophthalmic screening tests have been developed to detect early retinopathy. The aim of the current study was to evaluate the value of central 2-10 perimetry method in early detection of retinal toxicity...
