Journal of the Medical Association of Thailand Vol 94, No 3:MARCH 2011 (SUPPL.2) 0125-2208 94 3 2011 Mar Optic Disc Area and Diameter of the Central Retinal Vein Occlusion Fellow Eyes, Determined by Optical Coherence Tomography 76 EN Boonsong Wanichwecharungruang Phornpimol Jaksataphorn Kanokwan Yuttitham Sumeth Vanichvaranont Kitipong Harncharoen Original Article To investigate the diameters and disc area of central retinal vein occlusion fellow eyes (CRVO fellow eyes), whetherthere is any small diameter of the particular axis, which predisposing to central retinal vein occlusion (CRVO), or not. A prospective analytic study between 78 CRVO fellow eye patients and 102 healthy control subjectswas evaluated. Fast optic disc scan with Stratus OCT was obtained. Six axes of disc diameters, and disc area were not different between the groups. Analysis of the model excludingglaucoma within the study group (n = 59) revealed the similar outcome. Optic disc diameters and size in the CRVO fellow eyes were not different from normal subjects. Optic disc sizeappears not to be the pathogenesis of CRVO.
