Enhancing Patient Understanding: The Impact Of Educational Videos On Ophthalmology Visits, Anna Zhao Mar 2024

Enhancing Patient Understanding: The Impact Of Educational Videos On Ophthalmology Visits, Anna Zhao

Medical Student Research Symposium

A major component of effective patient-centered care is the patient’s understanding of their health condition and treatments. Increased knowledge of medical conditions can positively modify health behaviors, such as more participation in cancer screening and better adherence to medications. However, the readability of educational materials often does not match the patients’ reading abilities. Instead, educational videos, which have gained prominence with the emergence of tele-visits following COVID-19, have shown promise in being beneficial to patients with lower literacy levels. For ocular pathologies, early identification and care are key in preventing vision loss. Tele-education in ophthalmology could increase patient awareness of …
