Serous retinal detachments in thrombotic thrombocytopenic purpura
S. R. Lambert, K. A. High, E. Cotlier and E. J. Benz Jr
Serous retinal detachments are a rare ocular complication of thrombotic
thrombocytopenic purpura (TTP), with only six previous case reports in the
literature. We have recently observed two patients with relapsing TTP who
developed bilateral serous retinal detachments during acute exacerbations
of their disease. In contrast to all but one of the previously described
patients, both of our patients survived the episode during which retinal
detachments occurred. Hypertension appears to contribute to the development
of retinal detachments in TTP, and vigorous efforts at blood pressure
control are indicated. Serous retinal detachments may be a more frequent
component of chronic relapsing TTP than has been suspected.
