[Additional ultrasonographic criteria in the differential diagnosis of congestive and pseudocongestive optic disks].
Patients with congestive and pseudocongestive optic disks (OD) at the stages of early and completely developed edema, pseudocongestive OD, and control group patients were examined to study the possibilities of a comprehensive ultrasound study in the differential diagnosis of these conditions. As additional criteria in the differential diagnosis, the author proposes a 30 degrees negative test in pseudocongestive OD, a positive test in half the patients with congestive OD, the presence of drusens in most patients with pseudocongestive OD, the decrease in all blood flow velocity values in the central retinal artery, which is characteristic of patients with congestive OD, the increase in all blood flow velocity values in the ophthalmic artery, which is characteristic of patients with pseudocongestive OD.
