Nine patients had birdshot retinochoroidopathy. Associated ophthalmologic
findings included rhegmatogenous retinal detachment, rubeosis iridis,
glaucoma, and a high incidence of disciform macular degeneration. Four
patterns of birdshot spot distribution were noted on fundus examination.
Immunologic studies showed a significantly elevated percentage of EA
rosettes and an elevated C4 complement level. Electroretinograms showed
b-wave amplitude reduction, with a disproportionate implicit time
prolongation. The etiology of this syndrome remains unknown.
