Before intravitreal injection music intervention: These patients received the standard treatment and listened to music for a period of 15 minutes 30 minutes before the injection.

During-intravitreal injection music intervention:These patients received the standard treatment and listened to music during the injection (approximately 5 minutes).

The music intervention was not conducted with the patients in the control group. These patients received the standard treatment.

The patients in the Before-IVTI group listened to music for a period of 15 minutes 30 minutes before the injection.

VAS-A is a measurement tool, in which 0 represents feeling "no anxiety" while 10 represents "I feel extremely anxious".29 An increase in score indicates an increase in the anxiety experienced by the patient. This indicates that VAS-A is a reliable and accurate measurement tool despite its brevity. The VAS-A scale was applied to patients before, immediately after, and 15 minutes after the injection.

VAS scale is a single-dimensional scale that is commonly used to evaluate pain severity. According to the VAS, pain severity is rated from 0 (no pain) to 10 (the greatest imaginable pain). Any score under 3 on the scale is considered "mild pain", scores between 3 and 6 are "moderate pain" and any score above 6 is "severe pain". The VAS was applied both immediately after the injection and 15 minutes afterwards in order to determine the severity of the pain that the patients felt during the injection.

Numeric Rating Scale (NRS) was used. This scale allows for a score of between 0 and 10 points.A score of 0 indicates that the patient was totally noncompliant with the surgeon's instructions and a score of 10 indicates that the patient was totally compliant. The NRS was used by the surgeon for each patient immediately after the conclusion of the injection.
