Ophthalmologic Surveillance Program
Regular retinal imaging and examination to track changes in arterial-arteriolar morphology and assess cardiovascular risk implications. Serial photography helps detect progression or improvement in vascular changes.
Cardiovascular Risk Reduction
Systematic approach to blood pressure control, smoking cessation, and weight management to improve retinal vascular health. Lifestyle modifications address root causes of arterial-arteriolar changes.
Additional treatment options
Cardiovascular Diagnostic Workup
Comprehensive cardiac evaluation including echocardiography, stress testing, and vascular imaging to identify systemic contributors to retinal vascular abnormalities. Results guide multidisciplinary management.
procedureAntioxidant-Rich Nutrition Protocol
Dietary modifications emphasizing omega-3 fatty acids, leafy greens, and antioxidant-rich foods to support vascular health. Mediterranean-style dietary patterns have demonstrated benefits for retinal vascular function.
dietarySystemic Vascular Protective Therapy
Pharmacological management of underlying conditions such as hypertension, hyperlipidemia, or diabetes with vascular-protective agents. Tight glycemic and lipid control supports retinal vascular improvement.
