Unfortunately, the cocaine test has drawbacks: (i) some clinicians find it difficult to obtain the drug owing to its scheduling status, and in some countries it is not available at all; (ii) cocaine inhibits the uptake of hydroxyamphetamine from the nerve terminal and the two tests therefore cannot be conducted on the same day; (iii) metabolites of cocaine may remain in urine for up to 2 days after an ophthalmological test, which has implications for patients who may be subjected to a drug-screening test of their urine; (5) (iv) sensitivity of the test is reduced in cases where the interruption of the sympathetic pathway is incomplete; and (v) the response in patients with dark irides may be extremely slow, and up to 3 hours should be allowed before interpreting the results.
