Straightforward and Actionable Vision Test Results: Diopsys® ffERG/Flicker Reports


INTRODUCTION:

One of the perceived barriers associated with visual electrophysiology is that testing is complicated, and interpretation of the results requires the input of a neurophysiologist. While this may be true of older devices, the electrophysiology testing on Diopsys platforms are specifically designed to be much friendlier – both for the patient and for the clinician.

There are a few key parameters on the Diopsys® ffERG/Flicker reports that clinicians need to understand for this testing to provide actionable information for clinical decision making. Once understood, these vision test results will improve the ability to understand the health of the retina for enhanced patient management.

The Gold Standard for Uveitis Treatment Management

Posted by William Ayliffe, FRCS, PHD on December 3, 2018 at 2:02 PM

INTRODUCTION:

Broadly speaking, uveitis is inflammation affecting the uveal tract, although management and prognosis for vision loss differs significantly according to what part of the eye is affected (i.e., anterior, posterior, intermediate, or panuveitis). Thus, prompt identification and localizing of inflammation is critically important, even though early indicators of active disease are often subtle and may not be apparent on clinical examination or on imaging.

For patients with uveitis and suspected retinal involvement, results from a flicker electroretinogram (flicker ERG) are extremely useful for making a diagnosis and monitoring disease activity. Clinicians can identify retinal dysfunction early then see functional improvement on the flicker ERG after the introduction of anti-inflammatory treatment with steroids or immunomodulatory therapy. An improvement in retinal function can indicate the plausibility of tapering the drug dosage.

Tips for Building a Social Media Presence for your Eye Care Practice

“A brand is no longer what we tell the consumer it is – it is what consumers tell each other it is.” – Scott Cook, Founder, Intuit

INTRODUCTION:

Social media has significantly changed the rules for engaging patients. From Fortune 500 companies to mom-and-pop enterprises, companies of all shapes and sizes are increasingly harnessing the power of platforms like Facebook, Instagram, LinkedIn, and Twitter to generate discussion and build their brand. Virtually every sector of business, healthcare included, is feeling the impact of social media.

The Evolution of Objective, Functional Testing in Ophthalmic Practices

Posted by Diopsys, Inc. on September 22, 2018 at 3:29 PM


Diopsys Turns 20!

INTRODUCTION:

Twenty years ago, visual electrophysiology testing was not widely used in the eye care office, and its importance to routine clinical practice was poorly understood. Diopsys has changed all that.

The early experience with visual electrophysiology is hardly reflective of how this testing is used in modern eye care today, especially with the advent of smaller platforms and streamlined protocols. Even as new diagnostic technology has entered the eye care space, electrophysiology testing has gained a more prominent role in evaluating patients, precisely because no other testing modality can deliver both objective and functional information about the health of retinal cells. For eye care specialists, that kind of data is indispensable for deciding who to treat and how to treat.

“It's another tool in the toolbox,” said Mark Latina, MD, “We think we understand a lot of diseases, we think we know what we are doing, but this testing gives us an objective functional approach to patients, and that is a huge benefit.”

Light Induced Visual-response (LIV)

Introduction:

Light Induced Visual-response (LIV) measures the electrical responses of cells within the eye upon stimulation by a light source. Various stimuli can be used to target different cells within the visual pathway to gain objective information regarding their function, thus allowing clinicians to detect even subtle changes in cell health and viability. But what is the real value of LIV?

With objective, functional data, Light Induced Visual-response allows for tailored treatment and more precise disease management.

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.

Ophthalmology Spotlight: How Patients Benefit from ERG Vision Testing

Posted by Diopsys, Inc. on March 29, 2018 at 8:49 AM

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.

Retina Focus: How Do You Know if Treatment is Working?

Posted by William Ayliffe, FRCS, PHD on March 5, 2018 at 3:43 PM

The utility of objective, quantitative metrics for making treatment decisions.

INTRODUCTION:

Determining the effectiveness of treatment in a patient with suspected retinal pathology can be challenging. While visual acuity can serve as a benchmark, vision gains do not necessarily correlate with improvement in structure or global function. Despite the array of diagnostic modalities available to the eye care expert, very few of them deliver actionable information that is helpful in deciding if treatment is working, when to change course, or perhaps even when to cease treatment because risks outweigh the potential benefits.

Diabetic Retinopathy Management: An Advanced Approach

Posted by Alberto González García, M.D., Chief Medical Officer, Diopsys on February 1, 2018 at 9:43 AM

INTRODUCTION:

Patients with diabetic retinopathy can present difficult clinical questions, even to the most experienced experts. Whether and when to administer treatment and how to gauge effectiveness are topics that have been front and center in eye care for a long time. More fundamentally, understanding precisely how the disease is affecting the health of the eye has proven challenging, because while measurements like vision loss signify disease progression, visual acuity recovery after treatment does not necessarily correlate with improvement in underlying structure and function.

The Reason This Ophthalmologist Uses Flicker ERG

Posted by Mitchell A. Jackson, M.D. on December 9, 2016 at 3:09 AM

INTRODUCTION:

All of us anterior segment surgeons have coached our patients through the cataract surgery procedure and what type of vision they can expect when fully healed. The potential for diagnosing an existing retinopathy in patients with mild cataracts prior to surgery is relatively high. But predicting retinopathies and setting the proper patient expectations become more difficult when a dense cataract prohibits me from getting a reliable OCT or fundus photo. So what do I tell these patients? 

Now I have a reliable, objective test of retinal function that I can perform pre-operatively to give me an idea of what's going on behind the cataract. Flicker ERG has helped me ensure that these patients are accurately prepared for the outcome of their surgery.
