Clinical Features and Visual Prognosis of Retinal Vein Occlusion in Those under 50 Years Old

Purpose: To analyze the clinical features and visual prognosis of retinal vein occlusion (RVO) in patients under 50 years of age.Methods: A retrospective analysis of medical records of 36 patients under 50 years of age diagnosed with RVO from January 2016 to October 2021.Results: The mean age was 39.53 ± 9.98 years and 50%, 44.4%, and 5.6% had branch, central, and hemi-central RVO, respectively. Before the RVO diagnosis, systemic disease had been diagnosed in 38.9%. Further, 13.89% of the cases had a new systemic disease diagnosed after the diagnosis of RVO. Hypercholesterolemia was observed in 47.6%. The initial visual acuity (VA), best corrected visual acuity (BCVA), and central subfield thickness (CST) showed significant correlations with the final VA, BCVA, and CST.Conclusions: In patients with RVO under the age of 50 years, the initial VA and CST can be used as indicators to determine whether treatment is necessary by reflecting the final VA and CST. The initial VA and CST can also be used to predict the visual prognosis. Even at a young age, if complications occur, the visual prognosis of RVO may be poor, so an evaluation of the patient’s general condition is essential, especially the blood cholesterol level.
