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.

Aims and Objective - The aim of the present study is to identify risk factors associated with different retinal vascular occlusive diseases (RVOD), such as central retinal artery occlusion (CRAO), hemi-retinal artery occlusion (HRAO), branch retinal artery occlusion (BRAO), cilioretinal artery occlusion (Cilio-RAO), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and hemi-retinal vein occlusion (HRVO). Patients and Method - A cross-sectional study on 114 consecutive subjects, aged 24-96 years who have attended at the outpatient department of ophthalmology at Shyam Shah Medical College, Rewa, MP, were included in the study. The Duration of study was January 2016 to December 2017. Only patients with CRAO, BRAO, HRAO, Cilio-RAO, CRVO, BRVO, and HRVO were included in the study. Other retinal vascular disorders such as diabetic vaso-occlusive disease, anterior and posterior ischemic and non-ischemic neuropathy, hypertensive retinopathy, sickle cell retinopathy, retinal telangiectasia, retinopathy of prematurity, were excluded from study. Results - We have included 114 patients, 64 cases (56.14%) males, 50 (43.85%) females, aged 56+/-8 years (range 24-96 years).  Bilateral retinal vascular occlusive disorders were seen in only 4 cases (3.5%). Two patients have bilateral CRVO followed by one case of bilateral BRVO and one case of bilateral CRAO.  Out of 114 patients, branch retinal vein occlusion was seen in 62 cases (54.38%), followed by central retinal vein occlusion in 36 cases (31.57%), CRAO in 8 cases (7.01%), and hemi- retinal vein occlusion in 4 cases (3.50%). Hypertension was the most common, (40 cases, 35.08%) risk factor identified for retinal vascular occlusive disorders followed by diabetes 24 cases (21.05%), combined diabetes and hypertension in 22 cases (19.29%), and atherosclerosis in 18 cases (15.78%). Conclusions - Retinal vascular occlusive diseases have systemic as well as ocular risk factors. Understanding of these risk factors is essential for proper treatment of RVOD. Timely identification of risk factors for RVOD may helpful in decreasing ocular and systemic morbidity in these patients.

Background. Ocular vascular occlusions following intraocular procedures are a rare complication. We report a case series of patients with retinal vascular occlusions or anterior ischemic optic neuropathy (AION) after anterior and posterior segment surgery and demonstrate possible risk factors. Methods. Observational case series. Results. In ten patients, vascular occlusions were observed within ten weeks after intraocular surgery: branch retinal arterial occlusion (BRAO) (n=2), central retinal artery occlusion (CRAO) (n=2), central retinal vein occlusion (CRVO) (n=1), branch retinal vein occlusion (BRVO) (n=1), anterior ischemic optic neuropathy (AION) (n=3), and combined central artery and vein occlusion (n=1). AION occurred later (27–69 d) than arterial occlusions (14–60 d) or venous occlusions (1-2 d). In all cases, either specific surgical manipulations or general vascular disorders were identified as risk factors. In addition to general cardiovascular risk factors (arterial hypertension n=6, diabetes mellitus n=4), internal workup disclosed bilateral stenosis of the carotid arteries (n=1) and myeloproliferative syndrome (n=1). Conclusion. Vascular occlusions after surgical ocular procedures seem to be more frequent when cardiovascular diseases coexist. Surgical maneuvers and intra- or postoperative pressure changes may act as a triggering mechanism in patients with underlying systemic cardiovascular disorders. Affected patients should undergo thorough internal examination to identify possible underlying diseases.
