简要总结
This study is evaluating the pupil dilation of Horner's Patients who have ever taken an alpha blocker such as Tamsulosin. Patients will undergo eye dilation as would occur at a yearly eye examination, but their pupil dilation measurements will be recorded.
详细描述
This study will enroll 10 participants who have a unilateral Horner's Syndrome AND have a history of taking an alpha blocker such as Tamsulosin. Participants will be recruited based on those two enrollment criteria, and after consenting they will undergo pupil dilation with 10% phenylephrine. Once fully dilated the pupil size will be measured. Pupil dilation size of the eye affected by the Horner's Syndrome will be compared to the eye not affected by Horner's. Primary study outcome is the comparative dilation size of the Horner's affected eye to the non affected eye in all subjects.
