Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 131 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 17 manufacturers reported payments, led by Regeneron Healthcare Solutions, Inc. at 36.8% of the total. Among optometrist clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 131 payments — averaging $35.98 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
