    ASRS 2013 Annual Meeting

    Dr. Lihteh Wu shares a study he presented at the ASRS 2013 Annual Meeting showing choroidal thickness fluctuates significantly throughout the day. Using SD-OCT in normal subjects, he reports the pattern and magnitude of diurnal variation of macular choroidal volume, suggesting caution in using choroidal thickness as a surrogate for treatment response.
