Insights
Choroidal neovascular membrane (CNVM)-associated macular hemorrhage increased during the COVID-19 lockdown due to delayed care. Identifying high-risk patients and improving communication can mitigate future risks.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Macular Degeneration
Background:
- The COVID-19 pandemic and associated lockdowns disrupted routine medical care, potentially impacting patients with chronic conditions.
- Choroidal neovascular membrane (CNVM)-associated macular hemorrhage is a serious complication of age-related macular degeneration, requiring timely treatment.
Observation:
- A retrospective case series analyzed 14 patients presenting with macular hemorrhage during the NYC COVID-19 lockdown (March-August 2020).
- The majority of patients (86%) had COVID-19 risk factors, and most (93%) delayed seeking care without physician consultation.
- Many patients had a history of prior hemorrhage (73%) or were on antiplatelet/anticoagulation therapy (57%).
Findings:
- Patients experienced significant delays in follow-up appointments, extending from an average of 50.4 days to 125 days.
- A high percentage of patients (71%) presented with symptoms lasting over a week, indicating delayed presentation.
- Pre-existing CNVM signs on optical coherence tomography were present in 86% of patients.
Implications:
- Documenting hemorrhage risks and COVID-19 factors can improve triage during future public health crises.
- Direct physician communication is crucial for high-risk patients to manage anxiety and understand vision loss risks.
- Proactive management strategies are needed to prevent vision loss in patients with CNVM during healthcare disruptions.
Purpose:
This work reviews ocular, systemic, and demographic factors contributing to presentation of choroidal neovascular membrane (CNVM)-associated macular hemorrhage after the New York City coronavirus disease 2019 (COVID-19) lockdown.
Methods:
A retrospective, consecutive case series was conducted of all established patients presenting with macular hemorrhage between March 22, 2020, and August 10, 2020.
Results:
Fourteen patients (mean age 82.2 years) were evaluated. Ten patients had active CNVMs, 1 had an inactive lesion that was last injected 2 years prior, and 3 had new conversions from nonexudative age-related macular degeneration. In the actively treated CNVM group there was a delay in expected follow-up from 50.4 days to 125 days. Eight patients with previously active CNVM (73%) had a history of prior macular hemorrhage. Eight patients (57%) were on some form of antiplatelet or anticoagulation therapy. Twelve patients (86%) had COVID-19-specific risk factors besides age, and all but 1 patient (93%) delayed care without discussion with a physician. Ten patients (71%) had more than 1 week of symptoms prior to presentation. Twelve patients (86%) had signs of CNVM on prior optical coherence tomography.
Conclusions:
Adequate documentation of potential risks for hemorrhage (particularly prior hemorrhage or presence of subclinical type 1 CNVM), as well as COVID-19-specific risk factors, would aid triage of clinic appointments in future lockdowns. High-risk patients would likely benefit from direct physician communication discussing their individual risk profiles to alleviate anxiety over clinic visits and communicate their risk of severe vision loss.
