Popis: Background: To analyze the clinical profile, presentation, possible pathophysiology, and outcomes of central retinal artery occlusion (CRAO) following blunt trauma in pediatric subjects. Methodology: The medical charts of subjects aged 18 years or less with a diagnosis of CRAO following blunt ocular trauma were analyzed retrospectively for demography, details of the trauma, ocular findings, additional imaging reports if any, and final outcome. A Medline search was done (key words like central retinal artery occlusion, blunt trauma, children, pediatric subjects, and adolescents) to gather information available in the literature on the subject. Results: A total of 11 patients (11 eyes), mean age of 14.3 ± 3.4 years, and 100% male preponderance, with an average time duration from trauma to presentation to the hospital of 8.1 days were included. Visual acuity ranged from no light perception (four eyes) to finger count at a 1 m distance. Intraocular pressure was raised in three patients, of which two were suffering from sickle cell disease. In two eyes, the CRAO coexisted with optic nerve avulsion and the cilioretinal artery was spared. Disk pallor was seen in six eyes as early as 12 days from the trauma. None of the cases revealed any bony fracture in the CT scan. Conclusion: CRAO was observed to be an important primary or contributory cause of visual loss in children following blunt trauma, reflex vasospasm being the most common etiology. Early onset disk pallor could suggest an underlying vascular compromise of both retinal and optic disk circulation in addition to direct disk damage.
