VALUE OF CLINICAL, LABORATORY PARAMETERS AND ANALYSIS OF RETINAL VASCULARIZATION IN PEDIATRIC PATIENTS WITH PORTAL HYPERTENSION

ABSTRACT BACKGROUND: Portal hypertension is one of the complications of cirrhosis and is associated with numerous systemic manifestations, including renal, brain, pulmonary, cardiac and vascular changes. In routine ophthalmological examinations performed at our service, we observed that some children diagnosed with portal hypertension had increased retinal vascular tortuosity. OBJECTIVE: 1. To evaluate the presence of retinal vascular abnormalities (vascular tortuosity) in children diagnosed with portal hypertension; 2. To investigate the association between retinal vascular tortuosity and the presence of gastroesophageal varices in these children; 3. To evaluate the use of clinical and laboratory parameters to predict the presence of gastroesophageal varices in children with portal hypertension. METHODS: This was a cross-sectional and observational study that included patients aged
