Purpoe To decribe the prevalence and incidence of lo of viual field among patient with birdhot chorioretinopathy (BCR) and to decribe the effect of therapy on uch field lo in thee patient. Deign Retropective cohort tudy. Method etting: ingle-center, academic practice. tudy population: Fifty-five patient with BCR evaluated from January 1984 through July 2006. procedure: Demographic, clinical, and viual field data were collected retropectively. outcome meaure: Viual field lo i defined a an abnormal viual field core on Goldmann perimetry within ix month of preentation and during follow-up; rate of viual field lo i defined a the number of degree lot per year. Reult Forty-eight eye of 24 patient had Goldmann viual field performed within ix month of preentation and of thee eye, 75% and 56% had abnormal field core for the I-4 and IV-4 iopter, repectively. Of the 28 eye of 14 patient that received immunouppreive drug therapy during the follow-up period, the rate of viual field “lo” prior to treatment wa 107 degree/year (95% confidence interval [CI]: 65, 148 degree/year) and 56 degree/year (95% CI: 5, 109 degree/year) for the I-4 and IV-4 iopter, repectively.
