To describe and evaluate the prevalence of intensive sport practising among patients with earlyonset central retinal vein occlusion (CRVO).


Intensive sport practising was evaluated in a consecutive series of 10 patients with CRVO who were younger than 45 years of age (mean age, 37.2 years) from a total of 154 patients with CRVO. Data based on personal and familial history, sport habits, cardiovascular examination and biological analyses with coagulation check up have been retrospectively analyzed.


Five patients out of ten had a normal medical check up (no arterial hypertension, no hyperlipidemia, thrombophilia or hyperhomocysteinemia). Numerous similarities have been observed for these patients: 1) existence of visual eclips linked to sporting efforts in the month prior to the decrease of visual acuity secondary to CRVO ; 2) worsening of visual acuity lossafter hemodilution for the three patients to whom it was proposed ; 3) intensive practice of sports with violent efforts (squash, tennis) in two cases or running (marathon) in three cases; 4) spontaneous disappearance of all clinical signs of CRVO with an increase of visual acuity in four cases upon stopping sport practising.


A particular profile with intensive sport practising could be isolated in early-onset CRVOs without risk factors. The similarities found for these young patients allow us to consider a particular physiopathology for CRVO, probably linked to an intensive physical effort.
