El Dr. Fraunfelder revisó registros de la OMS, la FDA y el National Registry of Drug-Induced Ocular Side Effectes. Halló 263 casos de problemas oculares relacionados con suplementos. Tras revisar la literatura médica mundial, descubrió otros 60 casos más.
Por ejemplo, originados por la cantaxantina, el Dr. Fraunfelder halló 30 casos de problemas oculares, especialmente relacionados con la retina, incluyendo depósitos de cristales. Siete casos de irritaciones y conjuntivitis grave habían sido causados por baños de manzanilla. También la Echinacea purpurea se asoció a irritaciones oculares y conjuntivitis. El consumo de regaliz, en siete casos, se relacionó con pérdida temporal de visión y pseudoaldosteronismo. La niacina fue asociada a disminución de la visión, edema macular cistoide, ojo seco y queratitis punctata superficial. En cuando a la vitamina A, en dosis alta, fue responsable de hemorragias retinianas y de presión intracraneal.
