The occurrence of a RVO in any patient warrants some degree of systemic workup. While many cases in elderly individuals occur in the presence of atherosclerotic risk factors and require minimal investigation, cases in younger patients (especially less than 50) warrant a more thorough investigation. The purpose of a systemic workup is to identify, treat, and optimize underlying medical conditions such as diabetes and hypertension to prevent non-ocular organ damage as well as the recurrence of a RVO. The occurrence of a RVO should be clearly communicated to the general practitioner so that he/she can take part in a systemic evaluation and assist in counselling the patient about risk factors.
