CENTRAL RETINAL VEIN OCCLUSION IN YOUNG PATIENTS Clinical Characteristics and Prognostic Factors

摘要

Purpose: To investigate the clinical characteristics and prognostic factors of young patients with central retinal vein occlusion (CRVO). Methods: This retrospective cohort study involved treatment-naive patients with CRVO. Medical records regarding basic demographics, predisposing factors, ocular characteristics, and treatments were reviewed and compared according to age at CRVO onset. Results: We enrolled 263 patients, of whom 69 were younger patients. Younger patients had higher prevalence of nontraditional risk factors including physical or psychological stress (P = 0.032), hematologic abnormalities (P = 0.003), and better visual acuity at baseline and last visit (all P < 0.001) and were unlikely to undergo intravitreal injections (47.8 vs. 68.6%, P < 0.001) during follow-up. Younger patients had higher prevalence of paracentral acute middle maculopathy (28.1 vs. 4.7%, P < 0.001). Older age (odds ratio = 1.165, P = 0.028), male sex (odds ratio = 7.074, P = 0.034), coexisting renal disease (odds ratio = 7.845, P = 0.050), and poor baseline visual acuity (odds ratio = 16.069, P = 0.002) were significant risk factors for poor visual outcomes in young CRVO patients. Conclusion: Younger CRVO patients had a milder clinical course with fewer treatments and were more likely to have nontraditional risk factors than older patients.
