This is Why You Need Multifocal ERG if You Have Plaquenil Patients

Testing for Chloroquine and Hydroxychloroquine Retinopathy

Introduction:
Although the exact mechanism by which chloroquine (CQ) and hydroxychloroquine (HCQ - commonly known as Plaquenil) induce retinal toxicity is not well understood, but it is recognized as a serious ophthalmologic concern because it is not treatable.1 Guidelines from the American Academy of Ophthalmology (AAO) on screening for CQ and HCQ toxicity recommend that all patients starting therapy receive a baseline screening followed by annual follow-up visits beginning at 5 years after the start therapy—although some individuals with certain high risk factors might require closer monitoring.1 Above and beyond their role in screening, eye care professionals have a valuable role in educating patients and medical colleagues about safe dosing, risk factors, and the need for screening.

An Interview with William I. Bond, MD, FACS:

After over 40 years in practice, William I. Bond, MD has gotten fairly confident in his ability to evaluate a patient in the clinic and understand the health of the eye. 

The kind of knowledge that only comes from interacting with patients of all ages and vision disorders daily is a valuable tool when working with a new vision loss patient. It is what helps Dr. Bond look at a patient with a cataract, for example, and have an awareness that something else might be going on, perhaps something unseen that is affecting one or more parts of the complex human visual system. It may be that the degree of refractive change a patient is experiencing is more profound than what is suggested by the stage of the cataract. Yet, what that “something else” might be is not always obvious.

What do I see on this VEP?
A Quick Waveform Review

Posted by Diopsys, Inc. on September 28, 2016 at 4:00 PM

INTRODUCTION:

Visual Evoked Potential (VEP) has been used for over 50 years in the clinical management of patients with a variety of vision problems. It was not until the last 10 years, however, that visual electrophysiology devices were made consistently available to the office-based eye care professional.

VEP test results give ophthalmologists and optometrists objective, functional information about the entire vision system. These test results often have a few components. Here is a quick review of the most important section: the pattern-reversal VEP waveform.

Diopsys, Inc: Our ERG and VEP History

Posted by Diopsys, Inc. on September 28, 2016 at 3:21 PM

INTRODUCTION:

Diopsys introduced its first visual evoked potential (VEP) device at the American Academy of Pediatrics meeting in 2004, and has been leading the visual electrophysiology space ever since. Our Research and Development program is very important to the success of our vision testing devices, and our customers have benefited from our continuous product expansions. In addition to all of the clinical research done in the last 16 years, we currently have 15 studies running at several prestigious institutions, such as:

  • Wills Eye Hospital
  • Doheny Eye Institute
  • New York Eye and Ear Infirmary
  • University of Pittsburgh Medical Center (UPMC)
  • UCSF Medical Center

Take a look at our brief history below to see where we came from, and where we're headed.
