Amsler Sign

Excerpt

Amsler sign (aka Amsler-Verrey sign) is present in Fuchs heterochromic uveitis (FHU). It is characterized by hemorrhage in the anterior chamber (hyphema) after anterior chamber paracentesis or entry with the microvitreoretinal blade during anterior segment surgeries, including cataract surgery or minor trauma. This hemorrhage is due to the presence of fine, fragile vessels in the angle of the anterior chamber. The sign got its name from Dr. Marc Amsler and Dr. Florian Verrey, who described it in 1946.
