Objective : To investigate the diameters and disc area of central retinal vein occlusion fellow eyes (CRVO fellow eyes), whether
there is any small diameter of the particular axis, which predisposing to central retinal vein occlusion (CRVO), or not.
Material and Method: A prospective analytic study between 78 CRVO fellow eye patients and 102 healthy control subjects
was evaluated. Fast optic disc scan with Stratus OCT was obtained.
Results : Six axes of disc diameters, and disc area were not different between the groups. Analysis of the model excluding
glaucoma within the study group (n = 59) revealed the similar outcome.
Conclusion : Optic disc diameters and size in the CRVO fellow eyes were not different from normal subjects. Optic disc size
appears not to be the pathogenesis of CRVO.
