This study was a long term follow-up of 11 young adults aged 15-45 with central retinal vein occlusion (CRVO). Seven patients classified as the ischemic type of CRVO showed a poor visual acuity at the first examination and did not improve throughout the study. In addition, systemic diseases were found in all these patients. Four patients classified as venous stasis retinopathy type of CRVO, had, in contrast, fairly good visual acuity at the first examination and showed additional improvement during the follow-up period. No systemic diseases were detected. Physical examinations are recommended periodically for young adults with ischemic type of central retinal vein occlusion.
