3

Regular ophthalmologic examinations

Frequent eye exams including visual field testing and retinal photography to track progression of microvascular abnormalities and detect early complications.

monitoring

Additional treatment options

Intravitreal anti-VEGF therapy

Injection of vascular endothelial growth factor inhibitors into the eye to address abnormal neovascularization and reduce vascular leakage when present.

medication

Systemic health optimization

Management of underlying conditions such as hypertension, diabetes, and cardiovascular disease that may contribute to or worsen microvascular abnormalities.

lifestyle

Laser photocoagulation

Targeted laser treatment to ablate abnormal blood vessels and prevent progression of microvascular changes that threaten vision.
