An eye on how patients perceive their retinal diseases

A recent study identified a large disconnect between patients with neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME) who are treated with intravitreal injections. The survey results highlighted the significant treatment burden experienced by these patients and the need for targeted education and counseling to improve their satisfaction and outcomes.¹ Katie Robinson, PhD, and colleagues reported their findings in Clinical Ophthalmology. She is from the Office of Medical Affairs, Vindico Medical Education, Thorofare, NJ.

“From the patient perspective, the burden of anti-vascular endothelial growth factor treatment extends beyond the clinical setting,” the investigators stated.

These “logistical challenges” to the regular visits include barriers to transportation, absenteeism from work, the need for a caregiver,^2-4 side effects in about 50% of patients from the injections that require time off from daily activities and work to recover,² and significant fear and anxiety related to the injection procedure³. Additional emotional and psychological factors include fear of vision loss, depression, and anxiety about long-term disease management.^3,4 

In some cases, patients may need psychotherapy, support groups, and services for those with low vision^5,6 and experience a financial strain associated with the direct and indirect costs of their care.³

Patients also reported dissatisfaction with the injection frequency and the cumulative toll of ongoing treatment of AMD and DME.⁷ “These factors, combined with the physical discomfort and anxiety around the injection procedure itself, contribute to a multidimensional disease burden,”² the authors said.

On the flip side, physicians can underestimate the effects of these conditions on patient quality of life,^8,9 barriers that can result in nonadherence and undertreatment, contributing to suboptimal patient outcomes that are observed in real-world studies compared with the (VEGF) clinical trials.^3,10,11

Robinson and colleagues undertook this survey study to determine how patients with neovascular AMD or DME perceive their disease and its treatment and assess the degree of alignment between patient and clinician perceptions.

To that end, they developed three surveys: one tailored for patients with DME, one for patients with neovascular AMD, and one for clinicians who injected anti-VEGF agents to capture their data.

The surveys were completed by 101 patients, 50 with AMD and 51 with neovascular AMD in June 2024, and 100 ophthalmologists who treat these conditions.

What were the survey results of the AMD and DME patients?

The investigators reported the following key points:

1. 66% and 86% of patients with DME and neovascular AMD, respectively, reported receiving intravitreal injections at least once every 8 weeks.
2. 82% required a caregiver and/or public transportation to get to their appointments.
3. Vision loss over time and blurred or double vision were the most significant symptoms for patients with DME, and for those with neovascular AMD, poor night vision, seeing in low-light conditions, and blurred vision.
4. Dissatisfaction levels with education and counseling about their disease were higher for those with neovascular AMD, 31%, compared with DME (11%), which reached significance P< 0.01).
5. Ophthalmologists overestimated the extent to which patients perceived that injections were necessary and that patients experienced insurance barriers to receiving treatment (P < 0.01 for both comparisons).
6. They also overestimated the extent to which patients became less nervous with subsequent injections after the first injection and underestimated their difficulty of getting to appointments (P < 0.01 for both comparisons).

Robinson and colleagues concluded, “The findings of this survey study call attention to key barriers to effective treatment for patients and critical areas where patient and clinician perceptions of disease and treatment burdens are misaligned. Overall, these results underscore the large burden that patients face in undergoing treatment for neovascular AMD and DME. In the future, therapy that provides greater durability, fewer injections, and fewer clinic visits can help reduce the burden for patients, improve adherence, and facilitate better overall patient outcomes. Furthermore, optimal treatment will require greater understanding and communication between patients and clinicians.”
