GLP-1 and Its Impact on Health: Pearls and Pitfalls for Eye Care Professionals

03/14/25 • 46 min

In this episode of the Eye – Q Podcast, Dr. Rudrani Banik welcomes Ashley Koff, a renowned registered dietitian and founder of the Better Nutrition Program, to discuss the pivotal role of GLP-1 medications in managing diabetes, weight loss, and metabolic health. With her extensive experience in personalized nutrition, Ashley delves into how GLP-1 receptor agonists like semaglutide (Ozempic, Wegovy) are transforming diabetes management, and why eye care professionals should consider these medications’ effects on overall health, including eye health. The conversation explores how these treatments work, their potential impact on ocular health, and how nutrition and lifestyle choices can optimize their benefits.

Understanding GLP-1: The Metabolic Switch

GLP-1 (glucagon-like peptide-1) is an incretin hormone that plays a critical role in regulating insulin and glucose metabolism. In healthy individuals, GLP-1 is released after food consumption, particularly in response to proteins and fats, signaling satiety and stimulating insulin secretion. However, in many patients, especially those with diabetes, GLP-1 signaling can be dysfunctional or delayed.

Dr. Rudrani Banik, an integrative neuro-ophthalmologist, explains, “The GLP-1 hormone acts like a switch, activating a cascade of metabolic processes that regulate hunger, insulin production, and blood sugar control. Unfortunately, for many people, that switch is either delayed or suppressed due to diet, genetics, or environmental factors.”

The Role of GLP-1 Medications in Diabetes Management

GLP-1 receptor agonists are synthetic versions of the naturally occurring GLP-1 hormone. These medications work by mimicking the effects of GLP-1 in the body, leading to enhanced insulin secretion, reduced glucagon production, and increased satiety, thereby improving blood sugar control and promoting weight loss. This is particularly beneficial for individuals with Type 2 diabetes, who often struggle with insulin resistance.

Ashley Koff, a registered dietitian and founder of the Better Nutrition Program, shares, “GLP-1 medications are essentially a 24/7 supply of the GLP-1 hormone. While the body’s natural release of GLP-1 occurs briefly and only when food is present, these medications flood the system, leading to sustained metabolic effects. This is why people experience weight loss and improved blood sugar control.”

However, as Dr. Banik points out, “The flood of GLP-1 signaling can sometimes overwhelm the body, leading to side effects such as gastrointestinal distress or even delayed gastric emptying. For some patients, this can also affect nutrient absorption, which is crucial for eye health.” This brings us to the importance of considering the full range of effects GLP-1 medications can have on patient health, particularly in managing chronic conditions such as diabetic retinopathy.

GLP-1 and Ocular Health: Benefits and Considerations

One of the primary concerns with poorly managed diabetes is its impact on the eyes, particularly in the development of diabetic retinopathy. High blood sugar levels lead to blood vessel damage in the retina, which can result in vision loss. GLP-1 receptor agonists help lower blood glucose levels, which can directly benefit patients with diabetic retinopathy by reducing the likelihood of further damage to the retinal blood vessels.

However, there is emerging research suggesting potential risks associated with GLP-1 medications. For example, a recent study indicated a possible link between GLP-1 use and an increased risk of an eye stroke, or optic neuropathy, especially in individuals with pre-existing anatomical risk factors such as a crowded optic nerve. This study, published in a large Massachusetts database, highlights the need for eye care professionals to be vigilant when treating patients on GLP-1 medications.

Dr. Banik notes, “While GLP-1 medications can improve glycemic control and reduce the progression of diabetic retinopathy, there is emerging evidence that they may be associated with a type of eye stroke. It’s crucial...

Top 3 Branding Tips for Eye Care Professionals: Insights from Dr. Angelica Cifuentes

Branding is more than just logos and slogans; it’s about sharing a story that resonates with patients on a deeper level. In a recent episode of Defocus Media, Dr. Darryl Glover spoke with Dr. Angelica Cifuentes, an optometrist known worldwide for her authentic and impactful personal brand. Dr. Cifuentes shared her top three branding tips that every eye care professional should embrace to build a powerful and authentic brand. These tips focus on the power of storytelling, the importance of social media, and the unmatched value of authenticity.

Tip #1: Share Your Story Tip #2: Leverage Social Media Effectively Tip #3: Be Authentic – It’s Your Superpower

In this article, Defocus Media dives into these top three tips, providing actionable strategies for eye care professionals looking to elevate their brand.

Tip #1: Share Your Story

According to Dr. Cifuentes, one of the most powerful tools in branding is personal storytelling. Patients connect not just with the services offered but with the journey behind those services. Sharing your story helps humanize your brand, making it relatable and trustworthy.

To effectively share your story, start by reflecting on the pivotal moments that defined your career in optometry. Maybe it was a challenging case that reignited your passion or a personal experience that emphasized the importance of vision care. By weaving these stories into your social media posts, blog articles, or patient interactions, you can create an emotional connection that sets your brand apart.

Dr. Cifuentes also emphasized that every story is unique, and that uniqueness is a brand’s greatest asset. Eye care professionals should embrace their individual journeys without the pressure of appearing perfect. Authenticity in storytelling not only attracts patients but also strengthens their loyalty to your brand.

Key Takeaway: Share personal experiences that highlight your journey in optometry. Authentic stories build trust and make your brand more relatable.

Tip #2: Leverage Social Media Effectively

In today’s digital age, having a strong social media presence is essential for brand growth. Dr. Cifuentes highlighted the power of platforms like Instagram, Facebook, and LinkedIn for reaching a broader audience. Social media isn’t just a place to share updates—it’s a tool to educate, engage, and build credibility.

Consistency is crucial. Maintaining a regular posting schedule helps keep your audience engaged and positions you as an active and reliable source of information. Eye care professionals should focus on a mix of content, including educational tips, patient success stories, and behind-the-scenes glimpses into their practice.

Dr. Cifuentes also stressed the importance of video content. Instagram Reels, LinkedIn videos, and YouTube are powerful platforms for sharing quick tips, explaining eye care procedures, or showcasing patient transformations. Videos create a more personal connection and are proven to increase engagement.

Addressing common patient concerns is another effective strategy. Creating short, informative posts about managing dry eyes, the importance of routine eye exams, or tips for choosing the right lenses can position you as an expert in the field. This approach not only educates your audience but also builds trust.

Key Takeaway: Use social media consistently to educate and engage your audience. Video content, regular posts, and addressing common patient questions can significantly enhance your brand’s credibility.

Tip #3: Be Authentic – It’s Your Superpower

Authenticity was at the core of Dr. Cifuentes’ branding advice. In a world where patients can often detect inauthenticity instantly, being genuine is a powerful advantage. Authentic branding isn’t about showcasing a perfect image but embracing both your strengths and imperfections.

Eye care professionals can showcase authenticity by sharing real-life experiences, patient success stories, and even the challenges of running a practice. Dr. Cifuentes emphasized that being transparent about both the ups and downs of the profession not only humanizes your brand but also makes it more relatable.

Language is also key to authenticity. Speaking in a simple, relatable tone instead of medical jargon helps bridge the gap between professionals and patients. This approach makes information more accessible and builds stronger connections.
