Risk factors for central retinal vein occlusion in young adults

Abstract

Purpose: Several risk factors have been identified for central retinal vein occlusion (CRVO) in older population. CRVO in young is uncommon, and the risk factors for this group are unclear. This large retrospective, cross-sectional study used the National Inpatient Sample (NIS) database to evaluate the risk factors for CRVO in patients 18 to 40 years of age. Methods: The 2002 to 2014 NIS database was used. All patients 18 to 40 years of age with a primary diagnosis of CRVO were identified. Age- and gender-matched non-CRVO controls were randomly selected. The primary outcome was identification of risk factors for CRVO. Chi-square analysis and Firth logistic regression were performed with IBM SPSS 23 and R packages versions 3.4.3, respectively. p < 0.05 was considered significant. Results: A total of 95 weighted young CRVO patients were identified. The average age was 31.44 ± 6.41 years with no gender predilection. Systemic and ocular conditions found to have statistically significant associations with CRVO included primary open-angle glaucoma (POAG) (OR 836.72, p < 0.001), retinal vasculitis (OR 705.82, p < 0.001), pseudotumor cerebri (OR 35.94, p < 0.001), hypercoagulable state (OR 25.25, p < 0.001), history of deep vein thrombosis/pulmonary embolism (DVT/PE) (OR 21.88, p < 0.001), and hyperlipidemia (OR 3.60, p = 0.003). Conclusion: The most significant risk factors for CRVO in young adults were POAG, retinal vasculitis, and pseudotumor cerebri. Hypercoagulable states and DVT/PE were also associated with CRVO in this population. Systemic inflammatory conditions were not associated with CRVO. Traditional risk factors such as hypertension and diabetes did not pose significant risks, whereas hyperlipidemia was deemed a significant risk factor.

Review: The Development of Risk Factors and Cytokines in Retinal Vein Occlusion

“…Instead of glaucoma, there are other diseases which might be risk factors of RVO. Retinal vasculitis may be a more relevant risk factor in young CRVO patients ( 124 ). Central Serous Chorioretinopathy (CSCR) is idiopathic and often recurs.…”

Hemi- and Central Retinal Vein Occlusion Associated with COVID-19 Infection in Young Patients without Known Risk Factors

“…In a series of 95 patients diagnosed with CRVO between 18 and 40 years of age, Chen et al identified that statistically significant (p<0.001) risk factors for CRVO in young adults included primary open angle glaucoma, retinal vasculitis, pseudotumor cerebri, hypercoagulable state, hyperlipidemia, and a prior history of venous thromboembolic disease. 54 , 55 Other studies have identified that CRVO in young adults may be linked to smoking, migraine headaches, collagen vascular disease, medications (oral contraceptives, diuretics, sympathomimetics), and thrombophilia. 49 , 55 , 56 , 57 , 58 , 59 , 60 Young adults presenting with RVO may need a hypercoagulability workup to exclude systemic coagulopathies requiring anticoagulation, such as protein C and S deficiency, Factor V Leiden mutation, hyperhomocysteinemia, antiphospholipid antibody syndrome, prothrombin gene mutation, antithrombin deficiency, hyperviscosity syndrome, amongst others.…”

Clinical Features of Central Retinal Vein Occlusion in Young Patients

“…Currently, the literature defines CRVO cases in patients \ 50 years old as CRVO in the young [1][2][3][4][5][6]. However, some studies have defined CRVO in the young as that occurring in patients either \ 40 [7] or \ 55 [8] years old. Regardless, no age limit has been set to define CRVO in the young.…”
