Summary

This study is working on a tool to objectively measure pain and how well pain treatments work, especially for children and teens who may have trouble describing their pain. Researchers will use pupil responses to see how pain relievers affect nerve sensitivity. The study involves 120 participants aged 7 to 21 who are already receiving pain treatment at a clinic.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. The subject is 7 to 21 years of age 2. The subject is receiving an analgesic intervention in the Children's National Medical Center Pain Clinic 3. The subject is willing and able to provide written informed assent/parental consent to the study participation. Exclusion Criteria: 1. Eye pathology precluding pupillometry 2.
