 AB    PURPOSE: A previous dose-ranging study of foscarnet maintenance therapy
       for cytomegalovirus retinopathy showed a positive relationship between
       dose and survival but could not confirm a relationship between dose and
       time to first progression. This retrospective analysis of data from that
       study was undertaken to determine whether there was a relationship
       between dose and progression rates, which reflects the amount of retina
       destroyed when progression occurs. METHODS: Patients were randomly given
       one of two foscarnet maintenance therapy doses (90 mg/kg of body
       weight/day [FOS-90 group] or 120 mg/kg of body weight/day [FOS-120
       group] after induction therapy. Using baseline and follow-up photographs
       and pre-established definitions and methodology in a masked analysis,
       posterior progression rates and foveal proximity rates for individual
       lesions, selected by prospectively defined criteria, were calculated in
       each patient. Rates were compared between groups. RESULTS: The following
       median rates were greater for the FOS-90 group (N = 8) than for the
       FOS-120 group (N = 10): greatest maximum rate at which lesions enlarged
       in a posterior direction (43.5 vs 12.5 microns/day; P = .002); posterior
       progression rate for lesions closest to the fovea (42.8 vs 5.5
       microns/day; P = .010); and maximum foveal proximity rate for either eye
       (32.3 vs 3.4 microns/day; P = .031). CONCLUSION: Patients receiving
       higher doses of foscarnet have slower rates of progression and therefore
       less retinal tissue damage during maintenance therapy. A foscarnet
       maintenance therapy dose of 120 mg/kg of body weight/day instead of 90
       mg/kg of body weight/day may help to preserve vision in patients with
       cytomegalovirus retinopathy.
