Leveraging OCT & Modern ERG: An Anti-VEGF Treatment Case Study

Posted by Diopsys, Inc. on December 11, 2019 at 5:36 PM

Methods for evaluating the visual health and care for patients with retinal disease have changed dramatically in the last hundred years, but evaluation still requires multiple tools to obtain a complete picture of visual health. Modern electroretinography (ERG) is a valuable method available today that eye care professionals can use in conjunction with existing methods to support confident care decision-making, but some are unaware of the reliable data it provides and the benefits it offers for in-office testing.

Dispelling Myths Surrounding ERG CPT Codes

Updated ERG CPT Codes Find a Place in Practice

In January of 2019, the American Medical Association announced three new CPT Codes for electroretinography (ERG) which caused quite a bit of confusion among doctors and billers. Here are the facts:

LIV-ing for High Quality Outcomes After Cataract Surgery

Posted by Mitchell A. Jackson, M.D. on March 17, 2019 at 5:35 PM

INTRODUCTION:

Anterior segment surgeons already do many things to ensure their patients have a good experience during their cataract surgery operation, including multiple steps designed to get as close to the intended refractive target as possible.

In recent years, the addition of femtosecond laser to cataract surgery has helped make lens ablation easier, streamlined making incisions, and has helped ensure a consistent capsulorrhexis is made in each surgery. But the addition of laser is only one example of how ophthalmology has embraced high technology to help make the entire process more accurate and predictable. One could easily look at the variety of diagnostic tools used during the preoperative evaluation to help guide decision making and surgical planning for any number of examples.

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

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.
