Criteria

Inclusion Criteria:

  • Clinically significant or progressive retinal disease
  • Other ocular pathology
  • Patients with recent use of high-dose (>1 gm daily) salicylate therapy
  • Recent, current, or anticipated treatment with any medication that augments adrenergic responses, or precludes use of an alpha-adrenergic agonist
