Scientific Challenges in Postmarketing Surveillance of Ocular Adverse Drug Reactions

Reports in peer-reviewed medical journals may be proven incorrect over time. For drug-induced adverse ocular events, there is little true science after the drug reaches the marketplace, so the percentage of incorrect conclusions may be high. Clinicians should be wary of reports of adverse ocular effects until data are confirmed by multiple authors over the long-term. Even so, spontaneous reports from postmarketing surveillance databases may be the first and only signal of an adverse ocular event.
