—Dr Brooks and colleagues1 raised the question as to whether the vitreoretinal relationship can be used as an indicator of the risk for progression in an eye with retinal branch vein occlusion (RBVO).We reported the vitreous findings in a group of 50 eyes with RBVO and compared these findings with those of an age-matched control group.2 As Brooks and coworkers suggest, our findings were similar to those reported later in our diabetic patients.3The incidence of partial vitreous detachment was significantly higher (22%) in the RBVO group than in the control group (2.2% ) (P <.01). The incidence of preretinal neovascularization was 22%. No new vessels formed in eyes with complete posterior vitreous detachment. Sixty-four percent of the eyes with preretinal neovascularization had partial posterior vitreous detachment, while 36% had no vitreous detachment. In the eyes without preretinal neovascularization, 90% had either no vitreous detachment
